Great place! The food is excellent as well as the beer. Is there really anything else to say? My only gripe is that they only accept local checks or cash.

Being vegetarian, I tried to find a veggie-friendly restaurant that would please both me and my carnivorous family. This restaurant fit the bill! I had the veggie burrito and the black bean burger, both incredibly delicious. They got one of the sides wrong, but they immediately apologized and removed it from the check! Amazing service, great food, and short wait-time.

This was our first stop in Boulder and a memorable one at that. Awesome vibes and service. So damn peaceful. Great microbrewed craft beer - those stouts are nuts. At one point in the meal I just leaned back, took a look around and said something to the effect of "so this is Boulder, eh?" Felt like I had arrived. Part of me wishes I had never left.

If you love beer and friendly workers, you'll love this place. This is every hippie's dream cafe. A must stop whenever you are in town!

Sassy Jackson was our server. He's like a 50's superman. He collects tea cup poodles and poses with them. He wears a scarlet begonia in his hair, because he's a huge grateful dead fan, but he only likes that song. Btdubbs, he's too sexy for his job.

Food's good, staff's great, standard beers are pretty good, guest taps are hit and miss. It can be a little pricey though and honestly, not a huge fan of their fries.

Epic beer selection. I've been going here for years and I have never been disappointed. Consistent and great food is what you will find here. The portions are large and they nail it in terms of pub style food. Their IPA selection is diverse and interesting. They also always seem to have a good number of stouts and porters on tap too which I appreciate. At the bar they are very generous with sampling and bartenders have a plethora of beer knowledge. This is the place in Boulder to out and grab a beer. Mountain sun blows all other breweries in Boulder out of the water.

Good appetizers; super noisy in the way more and more places seem to be nowadays - it seems younger folks like this, but I don't get it...

Sure, the burgers are good and service is pretty nice, but they don't take credit cards. If this was reflected in their pricing it would be one thing, but it's not. The diner charging $5 for a burger doesn't take credit cards (understandably); the bar charging $3 for a micro brew doesn't take credit cards (understandably); but a restaurant at this price point? Pretty much inexcusable. Most folk just don't walk around with wads of cash in 2014, and some folk never use an ATM.

We had to wait nearly 30 minutes to get in to eat here and when we did i was less than pleased with the ambiance. it's a cross between a college dorm cafeteria and my great aunt's kitchen. i ordered the daily special sandwich that I REALLY didn't care for. it was essentially inedible. it had beets and goat cheese, but basically tasted like goat cheese smeared on white bread. It was dry and not at all seasoned well. I took one bite. Not only did the waitress not take it off my bill, but she never came back in time for me to order something else. I had to scrounge off everyone else's scraps. Ew. F.

Pretty good place! I had the grilled cheese and tomato bisque with the raspberry wheat beer and it was pretty good! The SO got the Rueben but didn't understand it was a tempeh Ruben aka soy product so he wasn't a fan. Overall good atmosphere and good food. Decent prices too!
(5)
Liz S.

I wasn't impressed with this place. Sure, the waitress didn't charge me for tasting all of their beers while trying to find one I wanted to drink with my meal, but I had to taste all of their beers while trying to find one I wanted to drink with my meal! Mediocre beer at best. Burger was tiny. Fries were oily. Good thing we brought cash.

If you are looking for mouthwatering food to go with your craft beer go to Mountain Sun. The #1 IPA (I think IPA, some sort of ale) is a must try. Flowery, slightly citrusy, and crisp it is everything I look for in an ale. Dangerous drinking these because they go down so nicely and have a beefy ABV. I suggest getting a flight of beers and sampling as many as you can as the price is great. Friendly service from multiple servers. The whole staff seemed pretty stoked to be working there. We even got a beer on the house just because it was our first time there! Last thing, the food. Simple, cheap, and yet of the highest quality. Burritos are bomb here. Go treat yourself!

Loved our visit to Mountain Sun! You know you are in a good place when they give you free samples of beer and free fries while you wit for your table. All the servers were so friendly and they all worked well together. All the food was excellent too!

Super casual with great beer. The wait can be daunting but it's very kid-friendly with board games and consistently good food. I wavered between 3 and 4 stars because of the wait and inconsistent service but if you're looking for great beer and good food to pair with the beer, this is the place to go. Be sure to remember that they don't take credit cards which is inconvenient but keeps the prices reasonable.

Weird, but I liked it. I can best describe this place as a dive, diner, brew pub???? I would try it again.

Very reasonably priced for craft beer--just $5 for a pint. They're known for their stouts and they deliver. I ordered the our gang stout. It was made with ingredients from Australia. My friends got a java stout and a nitro oatmeal porter. We were all satisfied but all agreed I made the best choice. :)

Probably one of the best burgers I have ever eaten. Service was outstanding and the craft beer was very good. I will definitely hit this place again when we visit Boulder

The food is really not so good. The burgers are frozen patties and best and the famous fries were quite soggy. The service was ok and the beer, was what was expected for an IPA.

Awesome little place. Good beer. Get the f.y.i.p.a. or the Java porter. Great deal on flights. Only got nachos for food and they were good.

The best burgers in Boulder, fresh cut fries, lots of great beer made on site. What's not to love about Mountain Sun? Be warned, if you come here on a busy night there will be a long queue. The loud, loose atmosphere may put you off if you're looking for anything close to an intimate dinner. Come for lunch if you want to avoid the crowds. You can sample any or all of the beers to find something you like, and you can even have a look in the back to see where it's made. The Date Night Burger is amazing and something you are not likely to find anywhere else. It has a sweet nutty flavor from the dates and nice smoky spicy kick from the grilled poblano peppers. Perfect medium rare both times I have ordered it, really delicious. The fries are excellent, cut fresh and perfectly crispy. Another place I'll miss back in Vegas.

Service here is top notch. The servers go above and beyond to help you choose just the right beer. The selection is diverse. I'm not a beer connoisseur, so I need some help. I was given 5 suggestions and little samples of each one. Awesome. Also had the reuben sammy which did not disappoint! Fun, casual vibe with a bit of street side patio as well.

Hanneke F.

So friendly, excellent brew, very generous with samples and recommendations. Good people watching in the outdoor space. Went here after trying out their sister pub on Vine Street in Denver (where thy actually brew in-house, so you can take a growler of your favorite home!). Thank you for the delicious birthday beer, Mountain Sun!

Rainey N.

This is an updated review. Since my first post, Mountain Sun staff has made a much more convincing effort to help me find something to eat that won't make me sick (dairy allergy). Last visit, I enjoyed a custom sandwich with dairy-free bread... and it was tasty! Plus we got some free fries and free beer. The manager was very attentive and helpful. The beer is still delicious, and now I can say the food and service are pretty good too. I'll go back. ;)

Damn it Yelp! You got us again! My boyfriend is a beer snob. So based on all of the yelpers raving about the porter and stuff. I dragged him to this place. It was totally not worth the hour wait. And no, the free taste of beer does not help. (The hostess will ask you if giving you a free tasting of beer will help make the wait more bearable.) Food - I had the fish tacos, the fish was breaded and served on a hard corn taco shell. I didn't like it at all. My boyfriend had the burger and fries. The fries were soggy and the patty was tasteless. Beer - "meh, it was okay" Service - The waiter took our order and since it was so busy, he didn't check on us or refilled our beverages.

A friendly fun place. The service is always top notch. The food is delicious and they even have some great vegetarian options. The beer is crisp and they'll let you sample a few to decide. Can be crowded during peak times, but waiting at the bar is also a treat to chat with the servers. After a long day of climbing the beer is a fabulous treat. Remember to bring cash because they don't accept credit cards.

This place makes me wish I could drink beer (I can't because I am allergic to gluten, not because I'm some kind of snob). Sadface. We went there for happy hour and every piece of food was delicious. The atmosphere is super cozy and the waitstaff were all very nice. Definitely a nice place for hanging out with friends.

Everything was great!!!! The food, the beers, and the SERVICE was great! We went as a group of 8 that included 4 kids (8-14). I called ahead and they put us on the list because it was a large group. We arrived and upon going in, I have to admit I wasn't sure it would be a good option with the kids. It is not very big and a bit loud. But at this point we would have a wait anywhere. We waited about 20 minutes after arrival, which was no big deal. We walked around pearl st. Watching the street performers and they called my cell when our table was ready. After being seated, we could sample any of the beers we wanted before ordering. The kids got board games from the bookcase and stayed entertained. And despite the noise level we were all still able to talk to each other and it not feel overpowered. The server who greeted us when we sat down said they all work as a team and any of them can help us. That was evident! Every time something was brought to us a different person was involved with our main server always checking in! They were all super friendly, personable, provided great service And were kid-friendly!! The food was great! Everybody loved the fries, Which we ordered to tide us over. We all commented with an air of surprise - these are REALLY good! Burgers, buffalo chicken, quesadilla, and the daily special - the Jerusalem plate were all good!! There were also gluten free options. They take cash only but there are ATMs inside and nearby. We will be back the next time we are in Boulder!!

I've been resisting reviewing the Mountain Sun for as long as I've been on Yelp because I haven't been able to think of any words to describe this piece of heaven. I still haven't thought of any, so please excuse me, but I just couldn't stand to not say something. I moved to Boulder in 2005, back when I thought of myself as a beer snob because I drank Heineken and Corona. One of the first restaurants I attended was the Mountain Sun. Obviously the food and drinks were amazing, but you probably already know that. What blew my mind was what happened when the check came. My partner and I discovered that the place was cash only and we had none of it; nor did we have an ATM card or checkbook, only a Visa. I thought we would be stuck washing dishes or have to promise them our first born. Instead, when I informed our server, I was told "Oh don't worry about it, you can get us next time." Say what? Even if the food and beer weren't the best on the planet, I would have returned simply for their style of doing business. Since that day I have been to the Sun (including Southern, Under the, and Vine Street Pub) hundreds of times and have never been disappointed. I leave Boulder often, but whenever I come back (and I always come back) the first thing I do is head to Mountain Sun and order myself an FYIPA and either a burger or the relatively new Speakeasy Steak sandwich. Just typing that makes my pants get a little tight.

Stopped in based on some yelp reviews I read--looks like the best burger in Boulder. We walked into an hour wait, but the hostess was nice enough to take my cell number and call me when it was ready, which afforded me the time to walk down Pearl. A gentleman called me and very enthusiastically told me our table was ready about 35 minutes later, which set a very positive tone for the meal. My friend and I sat down, and noticed that they didn't accept credit cards. We got up to leave, and our waiter and another gentleman working there practically begged us to stay, offering the ATM in the restaurant, or, my favorite part, offering to send our bill home with us along with a self address stamped envelope so we could pay later. He even brought out the envelope to show us. Class act, for sure. Our waitress was incredibly friendly and professional. Sorry to say I don't remember her name, but she had dark curly hair and some sweet boots on. On my way in, I had seen a patron eating fries with some sort of green sauce. I asked her if she by chance knew what it was, and she advised probably the vegetarian green chile. I ordered some to go with my burger, the Junk burger. The place was jumping and our waitress was super busy, so another waitress (some blonde girl) brought our food. She was not friendly at all. I remarked that the green chile was not what I had seen, and she stated 'did you order it?', and then left after I replied yes, stunned. I never got the green sauce I was looking for and we all wondered at my table why that girl was in customer service.... The burger was really good, moist and done medium rare just as requested. Fries were good as well--gotta say I loved the part on the menu where they state if your fries aren't up to par, they will replace them. The waitress came by specifically to check on our fries, which was nice. I would go back...but if I got that waitress who gave us our food, I would either leave or ask to be reseated. Their customer service was so good other than her.

Seriously, this place is totally amazing and worth all the great reviews here. This is hand-down some of the best beer I've ever had in my life. Their food was pretty darn delicious as well. The first person to greet us came over to ask about our tastes in beer, then brought us four samples he thought we would enjoy. Since my partner and I have different tastes, it was like we got to sample 8 different beers. It was love at first drink for me with the Annapura Amber - this is by far the smoothest amber ale I've ever drank - and the Raspberry Wheat. My partner greatly enjoyed the Kolsch and the Chazz Cat Rye. I sampled the Java Porter, the Chocolate Stout, and the Brown Ale. These were all good well. We decided to split the avocado and cheese sandwich to have something to snack on. Holy cow, this sandwich was amazing! The avocado tasted really fresh and I loved the flavor combinations. I highly recommend this place if you're in the area.

A lot of variety on the menu. I wanted to try about 10 different items. The fries are some of the best I have had. The Date Night Burger was amazing. Will definitely stop here again.

Billy R.

Where the locals go for pub food and fantastic micro brews. I've been eating (and drinking!) here regularly for years. I don't think I can recommend any other restaurant more highly if you're looking for an authentic Boulder experience and don't need the exorbitant prices or the pomp, but still want great food and beer. The only negative thing I can say is it is almost always packed because they're so awesome.

On the way back from hiking to Emerald Lake in the Rocky Mountain Nat'l Park, my son suggested we stop here -- it was 3 PM and we had to wait 10-15 minutes. It was packed. The hostess suggested we wait at the bar and have some free (free?) micro-brew beer tastings. What a great variety. They brew them all either at this location or at their Denver locations. The menu was typical bar food, but my quesadilla was stuffed with veggies and very tasty. My husband loved his burger. We didn't realize it was cash only, but it wasn't a problem.

Courtney B.

Long wait, but the burger I got was worth it! It had a fig jam and chilies on it and I got it on gluten free bread. So damn yummy! Hubby enjoyed his meal too. The service was decent once we were seated and things moved along OK from the kitchen. NOTE: this place is CASH ONLY and they conveniently have an ATM inside if you feel like getting raped in fees. :)

This place could easily charge double or triple there prices and it would still be well worth it. Great vibe and the outdoor patio is perfect for people watching on Pearl St!

Great beers, decent bar food. The catch is that they refuse to take credit cards and charge a fee on the atm that they make you use to pay them. The waiters also always refuse to split up the bill because 'it's too difficult'.

First brew pub I visited in Boulder, cash only was interesting but they had a ATM so it wasn't an issue. Very unique community table "walk in" seating if your friendly enough to mingle with others. Staff is very friendly & willing to help, most likely because it's a tip share economy for the workers there, which is very nice for the customers. Awesome beers & a very good food menu for a little bar. I have been going here & to their sister restaurants since I moved to Colorado & there is a cool rumor they made their name grilling cheeses at Grateful Dead concerts. Not sure if this is true but would make sense after seeing all the different art & great live music they display for their customers. I live across the street from the southern sun & I believe both restaurants will do take out. So I normally call ahead, if they are busy I'll order food & then grab a beer at the bar there while they prepare it. They are normally very quick in the kitchen for such high volumes, tasty beer while you wait. both have outdoor seating, community tables, board games. NO TV's! :~) which is a good thing here

If you are not into the packed-house, loose your voice just talking to the person next to you thing; you might want to try the main brewery, Southern Sun. I like the Mountain sun for the amazing beer but it's rare to find a place to sit with a group of four. I dig their tempeh reuben and definitely try as many beers as you can. They are my favorite brewery as far as beer quality goes in Boulder, fo sho!

I can't say much for the food, but as far as service goes - this place absolutely blew me away! My fiance and I stopped here for a couple beers yesterday after a full day of hiking around Boulder and because we were first timers our server comped TWO of our beers! Another server also came by with a free basket of fries for us to enjoy (they were delicious! but we didn't order any other food). They knew we were visiting from DC, and even though it's likely we won't be back in the area again for a long time they made it a point to take extra care of us. Clearly, they have enough business that they really didn't need to win over two more out-of-towners... so it definitely says a lot about their management and their time to treat us like that. Thanks Mountain Sun - we'll recommend you to all and definitely be back some day! :)

Beer sampler is awesome and we liked 5 of the 6 beers, which is rare for us as we are quite picky beer drinkers. Java Porter, raspberry wheat, Kolsch, white ale were all excellent. And the food, incredible food for the money! Great burger on wheat and wife had unbelievable vegan Reuben (how'd they do that!) We both loved out salads and left stunned at such an incredible price for the whole meal and beer sampling. Only downside is it can be a bit loud and crowded, but to be expected!

FANTASTIC! We travelled to Boulder from Ohio for a college visit. Our waitress gave us our first round of beers on the house as a welcome gift. And those beers were delicious. I ordered an IPA, my mom ordered a wheat beer. Their portion sizes were just what I'd expect for the price, but it wasn't so overwhelming that you couldn't walk around and enjoy Pearl Street after eating. I ordered a sandwich with mushrooms and various other vegetables. Honestly, I've never liked mayo in my entire life, but I decided to give theirs a shot (it's homemade) and I was so surprised! Nice and light, but a little bit tangy to counter the richness of the grilled veggies. This was the best meal I could have asked for after a stressful morning. The staff were just incredible and I felt so welcome. Our server was even just in her first round of training and she had such great control of her section. Can't wait to visit again!

Had dinner here last night. Very quick, friendly service. Had the raspberry wheat beer and it was outstanding! I had the winter chicken dinner. Shredded chicken cooked with thyme had a wonderful flavor, but the meat was a little dry. The Brussels sprouts, new potatoes and salad were very tasty. The place is very noisy and conversation can be difficult. They don't take credit cards. Very inexpensive. I look forward to going back next time I am in Boulder.

This place is an awesome local spot. Great food, good atmosphere, pretty fast service even when it's busy, and the employees actually care about keeping you happy without seeming like they're trying super hard. They're all just a chill bunch of people who are happy to serve you some good food and cold beer.

Awesome. Yummy beer and we happened upon free fries. Service was fast and friendly, can't speak to the other food menu. (Probably a place to drink more than eat)

The atmosphere is loud and fun, and surprisingly appropriate for both college students and families! And I love stout month every February! I hope they consider adding another stout month to the year as I always find amazing new beers that I probably wouldn't have found otherwise.

From the exterior, it seemed like the perfect place to have a beer and hang out seeing everyone taking in the perfect afternoon. On the interior, it was smaller than I thought but much more like a restaurant than I expected. There is really not much of a bar at all, which is a little surprising to me. Nonetheless, I squeezed in and the bartenders were all very attentive and helpful! Unfortunately, I can't say I'm a big fan of their beers with one huge exception: King Crimson. I've never had an Imperial IRA but this one knocked it out. It's worth the visit just for this. I didn't get a chance to eat here but I'd like to get back here and sit outside and have a beer and grub sometime.

The first time we passed this place my sister called it a Boulder institution, so I had to stop for a quick 8oz while the family shopped. I liked the first one a lot and might have stayed for another but the bar is really a counter with no stools so I decided to just come another time to try food. So Sunday night we arrived at 9:15 to find that the kitchen had closed and only late night stuff like chips and salsa was available. So we ate chips and tried several good beers, the most interesting one that I want to clone was a Java Porter. The real reason for the 3 stars vs four was the lousy service. They have an amazingly dumb system where no staff member has a title such as server, busboy, line chef, etc. and everyone rotates positions. As a server I can see why this is an attractive offer and makes work less boring, but in our case it also left me with the worst waitress in Boulder. We all know that waitering is not rocket science but practice does help and this chick must be a hell of a chef if she can be that bad of a server and keep a job. Ultimately my sister's use of the phrase "Boulder institution" seems accurate in that only here could you have a restaurant with lots of potential to be great but instead chooses to be crunchy and homey.

Great food and good beers... The best part is the service. The people who work here are amazing!!! Our server comped our first round since it was our first time in... He also chased out outside to give us our sunglasses that we left. All in all- great experience. We loved it!!!

Diana F.

Yummy food (is that a culinary term?). I opted for the eggplant Parmesan sliders just to try something different--I wasn't disappointed. The watermelon salad was a nice complement to the strong flavors on the sliders. Paired with the Annapurna Amber Ale, the entire lunch was enjoyable. The venue itself is a bit on the noisy side, but servers are accommodating.

Such great service and friendly wait staff! We were traveling through Boulder and only had a few hours to spare and Mountain Sun couldn't have been more welcoming! Lots of sampler beers and our first round on the house for being out of towners! Great atmosphere, would definitely go back.

We did some tastings while we waited for a table for lunch. Not the best beers I've ever had but good efforts and super friendly staff! Food was just eh for me, i got half&half the portobello sandwich was ok, had much better sandwich at murphys. The tomato bisque salty. I couldn't finish it My husbands fish and chips were to die for!! I was very jealous I didn't get them. The atmosphere was open, inviting, staff attentive and friendly. Wait not long.

We had such a great experience at Mountain Sun. Our young daughter was diagnosed with celiac a few months ago, and going out to eat can be a little stressful. She gets sick if she eats even a trace of gluten. We found Mountain Sun on a list of Boulder restaurants with gluten free menus. The hostess and our server could not have been more friendly and helpful. They immediately understood her restriction, and made several trips to the kitchen to make sure her meal was reliably gluten free. She had a burger with a gluten free bun and loved it. What we loved was the friendliness and helpfulness. We still feel self-conscious at restaurants with this new gluten free thing. The staff at Mountain Sun made us feel welcome, and they really went out of their way to ensure that we had a great dining experience. It meant a lot to a young girl who just wants to feel normal at a restaurant. It's worth the drive from Denver to Boulder to come back!

Popped in here for a burger and a brew while I was in Boulder. It's a lively friendly place at the start of the Pearl Street pedestrian area. The clientele run the gamut from students to crunchies to tourists so it's kind of a fun place to come in people watch. They are cash only so hit the ATM before coming in. The burgers are A-OK especially when washed down with a glass of Amber. I also love their spinach salad , a HUGE half salad was under $5 so that was a steal. The service is really friendly and everyone working there takes the time to make sure you're looked after and happy.

I ordered the Java Porter and was given the option of CO2 or Nitrogen to dispense my beer. That alone sets this place apart. The food too was excellent. I ordered the S.O.B. Burger and I would have to say that it ranks in the top three burgers I have eaten in Colorado. The staff was friendly, the environment was relaxed, and the price is reasonable; what more can you ask for?

I stopped here one day to pick up some growler before an afternoon BBQ and realized they only take cash, which I never carry. So after realizing I only had enough to cover one of the two growers I ordered, the waitress gave me a Karma Envelope, which allowed me to send in a check for my whole order to send back when I got home. I loved this! Only in Boulder can you get a Karma Envelope to pay later. No name was taken and they just wrote the price inside the envelope. Their beer is pretty good, but their growlers are just giant Mason jars, which make for a difficult pour.

Christine R.

I f'ing love this place. No joke. Been here once, going back again. Tonight. First of all, the vibe, the friendly staff, the restaurant's philosophy - they all add to the experience. And the food. OMFG YUM. My bf ordered the Date burger = this thing is famous. In addition to my bf, two other people raved about this burger unsolicited. That is what greatness is. What really won us over, however, was when the waitress asked if our burgers were cooked to our desired temperature (med. rare), we kindly responded that it was a little overdone, but no worries - they were still delicious and we really weren't complaining. Next thing we know, our waitress comes back to let us know that they are covering our drinks for the burger not being done to our specs. WHO DOES THAT? This place does, that's who. Seriously, this place is a blast - board games, good beer, good food, GREAT STAFF. Can't really ask for much else. Oh yeah, and the prices are very reasonable. I may just move to Boulder and when I do - this place is going to be my second home.

After a hike in Boulder we were really wanting an amazing local place to eat and grab a drink. My friend found this place in lonely planet so we headed over. Right away we were impressed with the customer service and the food! Extremely friendly and funny. They work as a team and it feels more like a family! They went above and beyond any typical restaurant. I personally never write reviews on the Internet but had such an amazing exerience that we felt compelled to share! We refused to leave the table until this review was written! If you are in Boulder you HAVE to stop by for a drink and some amazing food!

Been here many a time, drank many a beer. All brews on tap are their own with a good selection of everything from pale ales to porters to Belgians. Food is solid with huge props going to the dang jalapeÃ±o mayo dip for the French fries. Holy crap I wanna take a shower in it. The wait staff will be all over you, askin if you'd like ANOTHER beer or some MORE mayo dip and before you know it you're drunk and fat and starin at the hippie tapestries draping the walls and wondering why you haven't gone to a Phish concert or String Cheese Incident show in 10 years and how is Trey able to jam as hard as he does on that Languedoc 6-string for like eight hours at a time!! Man oh man. I forget to bring cash with me more often than not cause I'm super into technology and debit cards which is the one downside of this place: they only take cash. They do have this busted lookin ATM in the back but it only reads my card 50% of the time especially when all I want is another dang Annapurna Ale!! Overall the majority of their beers hit the sweet spot, the food will fill your gullet nicely (with daily rotating specials), and the wait staff will take care of you. They do not disappoint. I know the quality I'm getting when I go here and I always leave satisfied.

I arrived during the dinner rush. During the summer, it's hard to get a seat, but usually I don't have a problem in the winter. The wait list was short, and it gave me an opportunity to try a few beer tasters at the bar. I ended up getting a Cat Burglar, which was being poured as my table was called. It came in a snifter, which is always a good sign. It was high in alcohol content, but that's okay, because it tasted great. While waiting for my friends to arrive, I got some french fries to munch on. I didn't get the cheese on them, but they were delicious anyways. I can only imagine how good they would be if I had decided on the cheese. Mmmm. I was working on my second Cat Burglar when my friends arrived. I had already decided on the pulled pork burger. It was one of their daily specials, which means it probably won't be on the menu anymore. However, their daily specials are always good and I highly recommend all of them. The pulled pork burger was no exception. My friends and I stayed and talked over another beer before heading home.

On a group lunch with other co-workers. The ordering process was clean,simple and efficient. The order time was good and the meal was satisfactory. I find its lack of accepting credit cards a little odd and out of place, especially in this modern digital age. But Boulder is an eclectic town with its own special unique charm.

Come for the beer. Stay for more beer. Hands down this was my favorite place in Colorado for eating and drinking. I had a great meal that consisted of a juicy burger and fries. They probably have the best fries in the history of fries. However, their delicious food was overshadowed by there amazing beer. I drank the XXX Pale Ale, which will is one of the best beers ever brewed. They were also very generous with the beer samples. Whenever my travels lead me back to Colorado, Mountain Sun will be my first stop. They have a neat decor that reminded me of a really nice head shop. The service is sometimes confusing because it seems like everybody there is your waiter. So you're constantly looking for your waiter/waitress, but you apparently can get service from everyone. Once again I'll say that there beer is amazing. If you love beer this is definitely the spot for you. I wish that they would open up a Mountain Sun in Chicago. If they did I probably could single handily keep that place in business. I hope Mountain Sun reads this and opens a location in my city. If not, I'll just buy a one-way ticket.

Decided to visit Boulder and found that this was a high rated place so stopped by. Simply INCREDIBLE customer service. Everyone from the bar to waiters to the bussers were amazingly nice. Tried multiple samples of beers that were all delicious. Ordered the Raspberry Wheat in the end and a friend ordered the Colorado Kind Ale. Both were amazing! I was really impressed with all the employees and their knowledge of the drafts. The order of large fries is HUGE, definitely big enough to share between 4 or 5 people. The junk burgers were delicious. Shout out to Jon and Christine for some world class service. Definitely will recommend to friends and would visit again if I'm in Boulder!

Edit: The proprietor of Mountain Sun sent me an e-mail through yelp to apologize for the experience I had during my first visit to the pub. His email was so gracious, as was his email invitation to return, that I am inclined to think that my visit was just on an off-day, which can happen anywhere. I'm boosting my rating to A-OK for now and hope to update my review when I get a chance to return. --------------------------------------------------Â---------------------- Original review I don't get too upset when a restaurant makes mistakes; what does bother me, however, is when that restaurant puts the burden on the customer to fix the mistakes. I went to Mountain Sun for lunch recently. I ordered the half-sandwich/ soup combo. Apparently, the restaurant ran out of the soup I had ordered. Instead of letting me know BEFORE bringing my meal, the waitress brought out the soup I did not order with a casual, "Yeah, I just found out that we don't have the corn soup anymore. This is chicken noodle." After I gave her a blank look (because I don't like chicken noodle soup), she said, "Oh. Is that okay? Do you want it?" Not really, I said and asked if I could change my order to the salad (the other option for a half-sandwich combo). She said yes and then asked me to pick up the half sandwich from the plate and put it on a tiny butter plate in the meantime. I really didn't want to handle the sandwich right at the moment and make the messy move between plates, but whatever. After she left, I discovered that the avocado and cheese sandwich I ordered didn't have cheese. I found a server and told him about the mistake. "Oh. Uh. Do you want me to take this in the back and put some cheese in?" No, actually, I did not want what, a fourth person? handling the sandwich. I asked if he could make another. "Oh, uhh, okay, and I'll send the manager over." Maybe the woman who brought out my new sandwich was the manager, but I wouldn't know that since all she said was, "I just found out we were out of the soup of the day, too." After we had run out of things to mess up here, the order was still on our bill--most restaurants would have comped it. And the sandwich was kind of what the British would call "manky." I could have gotten a better one at Safeway. Way overrated.

All I wanted for dinner when I was in Boulder was a burger, and this place got the best reviews...So I tried it out. It was really busy on a Saturday evening, and I was dining alone, but they were kind enough to give me a table all to myself anyways. Good on them. I don't recall which burger I ordered, but they did a fine job cooking it to my medium rare specification. It was really a respectable burger, and accomplished exactly what I had in mind for it. The service was excellent; everybody working there was just the right amount of weird, and very friendly. This place definitely has a hip type of vibe to it. When it comes down to it, the food didn't blow me away, but exceeded what my expectations for a brewpub usually are. For that, it deserves a shot.

Great atmosphere, although the wait on a Sunday night was a bit much with no seats at the bar. The food was well worth the wait, and the beer selection was awesome. A lot of local breweries and a variety on the menu so a great selection for everyone's taste.

I have been here so many times and just realized I have never left them a review!! So, obviously I like this place, as I said, I come here often. First: Yes, they may get busy, so they may not be able to be shoved straight up your ass during the whole meal (who would want that anyway!?) but they are always so friendly, attentive, and just love to chat with you about local food, music, art, whatever. Plus (added bonus) everyone who is employed here is terribly good looking ;) Second: I have never gotten a burger here. I got the burrito once, and have never been able to switch off. Their vegetarian green chili is to die for, or they have one that has beef in it. That one is a red sauce and is pretty spicy, but also yummy. Also, I am big fan of their fries. I like to get cheese on mine. Third: The place is so cool and quirky. Cash only, but they will allow you to mail your check back to them!!! It is so weird, but they totally believe in humanity and karma, talk about a breath of fresh air! Also, if someone sends something back, or if something wasn't made right, instead of them throwing the food out, they will offer the food (as samples) to people sitting around the bar. They also always offer free samples of beer (and pretty much anything else). Fourth: Beer. Oh my, the beer. DELICIOUS. They have an amazing selection that is brewed in house and the selection will change seasonally. Also, moderately priced. We bring anyone visiting us from out of town here to sample the lovely beer, eat fresh, local food, and to see a restaurant that truly captures the essence and feel of Boulder!

Dare I say, I had the best burger I've had in Colorado here? Yes, I dare. Mountain Sun is so friggin hippielicious that I felt like I channeled the Grateful Dead just by sitting in there for an hour. We came here spontaneously on a Saturday afternoon with 15+ people and they were accommodating right off the bat. I couldn't have asked for better service and our server was giving us suggestions left and right on what to order food and drink wise. I've never been here before my visit this wknd but have been to Vine Street here in Denver and I felt like I was at the same place only a smaller location. Colors aside, a cool thing I love about Mountain Sun is that they let you sample beers until you "decide" on what beer you want. So, if you're ever looking for a place where you can explore different beers for free, Mountain Sun is the place! I tried a few IPA's until I decided on one that suited my taste and was in hoppy heaven with their FYIPA. In lieu of it being Cinco de Mayo, I chose to celebrate via food and ordered the Cinco de May burger. I've had some good burgers in my time in Colorado. Some have been mouthwatering, others more meh and these hippies make a mean burger. Simply put it-it was heaven in the form of a burger. Like anything good in life, it had a little bit of everything with a perfect balance: quality meat, cheese, PESTO (excited a little? Yes.) roasted peppers and squash. I wanted to moan at the table but didn't want to be a freak but it was definitely mouthgasm league. Kudos hippies and your burger and beer making abilities.

Great beer! Attentive waiter was nice and personable. I had the basil blue hamburger. It was good though it was still pinkish. This might bother some people. I ate all of it. When I finished it I realized I didn't remember tasting any of the blue cheese the menu described. The fries are not crispy. Cash only policy is bizarre in this day & age. Other reviewers are right: there is nothing to alert you to that payment policy until you see smallish print on the menu. This is a LOUD restaurant. I had to raise my voice the whole time to be heard. I would go again.

This is very trendy, normally not my scene but I needed to tell people how awesome the service is here. Best I've had in the states and I travel a lot. To the main bartender (maybe manager) he really knows how to set a scene and was amazing. Keep up the good work.

I have loved the sun since day one, almost 10 years ago. There used to be a sense of community and a desire to interact with local customers. It seems to me, since the expansion from 2 pubs to 5 they have lost their ability to give good service and appreciate those in the local community. I understand that capitalism is about the mighty dollar, but the sun used to be one of the quintessential boulder destinations. Now it is only a business that is concerned about money over community. I know that times change and so does the market. It would just be nice for someone to have 1 minute for a bar guest that doesn't want a table. The sun has some of the best beers In town, but since they can't keep up with production for 5 pubs with 3 breweries they can't keep their core beers on. I have always been impressed with the beer and it is the only thing that makes me return. The owners and the managers have accosted me at the bar based on my opinions of bands and my choice of clothing. I just want a friendly place to drink good beer that hasn't forgotten about the people that actually live in Boulder. Oh well I guess I can look forward to the day where their production is great enough to drink their beer at a place with better ambiance and service.

Service was good with a good attitude. They don't except credit card but if you don't pay they have something called a karma envelope and you can put the money in there to be mailed at a later time. What an original concept! If you don't know about they will let you try them. Centrally located on Pearl Street so it is a great place to grab a bite and walk around. Their raspberry beer was delicious flavorful and light.

Before you are shocked at my "only" 4 star review, know that I'm not really a beer drinker NOR do I eat much red meat. So, the two primary reasons you'd go here (beer and burgers) aren't things that interest me. Knowing this, four stars is actually pretty impressive! I did try the java porter and amber and both were excellent (5 star, ok?) for beer. My wife had a ginger beer and really liked it. Also, our server was awesome. 5 stars for him hands down. I had the pollo asado burrito - 3.5 stars. it was good and all, but nothing special. The kids shared a quesadilla which was your average quesadilla. We tried the fries because they were raved about by yelpers. They were 4 star. Good but not the best I've had. Also, get there early. I expected a big place and this place is pretty small for how popular it is If you're in Boulder, definitely worth a stop!

Although you can technically call this restaurant a "brewpub" by definition, what really defines this place is its flamboyant ode to nature and artistic expression. This place is far more than the purpose it serves as a business, or how it might be categorized in an internet search engine. One visit to this place and I knew it was special, unique and worthy of its own self-expressed definition. We arrived on a warm Saturday afternoon and business was busy as there tends to be a virtual parade of people on Pearl St during the summer. Mountain Sun, if you've read any reviews on the place, has garnered countless accolades by those that make this their food destination. As a brewery, they have covered an entire wall with medals earned in commercial brewing competitions. Clearly, they have been doing something right. We were told that there would be a brief 10 minute wait for a table, which is nothing to complain about on such a beautiful day. Eventually we were led to our table and I noticed that every table had something unique about it. There was custom artwork displayed in almost every observable space where one could imagine an artist finding enough room to move a paintbrush. It reminded me of Avogadro's Number in Ft. Collins, which is quite the spectacle in the same way. Visually, the restaurant engages the senses. I felt a sense of appreciation for those artists that took the time to share their artistic vision and made my experience more enjoyable. Our server was very impressive. In fact, the entire staff was terrific and I had no issues with any part of their service whatsoever. I was actually helped by several members of their staff and every one of them was seemed to genuinely care about our experience. We ordered samples of most of their beers on tap. All of which were tasty. The Colorado Kind Amber Ale was a more bitter version from others in the style, but quite good. We tried their trippel and saison which both had excellent esters and flavor balance. My favorite was their hybrid Belgian-American Pale Ale. This beer was the perfect choice for a summer afternoon with its refreshing blend of American hops and fruity Belgian yeast. The have a few versions of American IPAs, which were all subtly different in their bitterness and hop forward flavor profile but mostly about the same in alcohol content. I enjoyed those as well. Overall, they may not be on par with the more commercial production breweries in terms of quality, but for a brewpub I think they are excellent and worthy of their awarded recognition. The food was good, but not great. At the time they had a few special menu items. We had McMountain tacos and McMurray sandwich dishes. The tacos were seasoned well with a delicious combination of fresh ingredients, yet it was quite greasy (my plate was covered by the end of the meal with that coppery, shiny slime). My wife enjoyed the sandwich but didn't provide any criticism. I pecked at her Cajun seasoned fries and was disappointed due to the burnt charcoal like flavor that stood out more then the seasoning, not to mention they were fairly cold and quite limp and soggy. Overall, I give this place 4 stars, maybe 3 if I wasn't so impressed by their service and the general ambiance and dÃ©cor. I would definitely recommend this place!

Whenever I have visitors from out of town, I take them to Mountain Sun. The food is just a step above pub grub, the beers are AMAZING (and a plentiful selection, too), and the staff are all a bunch of hipster-like sweethearts. Honestly, it's just such a good, down-to-earth pub and brewery that you can't go wrong. The only thing holding me back from giving it 5 stars is that it's super small for the crowd that is always there. Expect a 30 minute wait for dinnertime and to share a brew with new friends made at the bar while you're waiting.

Management was very professional and offered compensation for lack of service during our visit after my review was posted. Although we no longer live in state, it's the thought that counts.

This place is great! The BOOM BOOM Sandwich really hit the spot, and I've been dreaming of it ever since... I also had a Java Porter on nitro stout that was amazing. The next time I'm in Boulder I'll be returning to Mountain Sun and likely ordering the exact same thing.

I love this place! One of my favorite stand-bys when I want good service, a friendly atmosphere, and delicious food. Would definitely recommend it! Just a quick note about a complaint made earlier about being cash only--they do have a sign outside noting that this is their system, and it is written on their menus as a reminder too.

Went to Mountain Sun for lunch on a family vacation and no one was disappointed. Everyone loved the food, and they even had options for vegetarians, which was nice. Beer was fantastic and the staff really friendly.

$13.25 for a pitcher of beer? I love this state. Mountain Sun Pub was the first place I sat down and had a beer in Colorado - and I'm sure glad we did. The menu is simple - very easy going and reasonably priced. The beer selection is pretty incredible (and also very reasonably priced). Place was jumping on a Wednesday afternoon when we strolled on in. No problem getting a seat though and our waitress was attentive, but not annoying. I washed my beer down with a simple grilled cheese with bacon. Perfect start to an incredible week in that great state. Both sad and glad I didn't go to college in Boulder, because if I had I would have spent a lot of money in this place. I mean... they have board games!!!!

Went here hoping for some pub food and good beer and it met my expectations with flying colors. They asked if we had been there before and when we said no, the waiter asked what types of beers we liked and promptly brought over 4 samples to aid in our decision. It was a difficult decision since they were all really good, but I ended up with the Black IPA and my wife had the Raspberry Wheat. Then came time for the food. There were a number of burgers and other meals that sounded good. I got the special wrap for the day and my wife got a burger and chips. Burger was cooked medium well just like she ordered and the wrap was very tasty. I would definitely recommend Mountain Sun for when you're craving some pub food or just looking for a place to go have some really good beers. The one thing to be aware of is that it is cash only, which caught me off guard. Luckily I had some cash on me.

Mountain Sun is Boulder! You cannot visit one without the other. The staff is awesome, the vibe is friendly and comfortable, and the food is great. Not to mention they brew their own beer and have an amazing selection on tap. Mountain Sun has great specials every day, ranging from the daily hummus to an entree they change up daily. The standard menu is great and I've always felt the ingredients here are fresh.

Brian K.

The staff was excellent. They were both informative, professional, and accommodating. The food just was not that great. Disclaimer: I ordered out of my palette range of comfort. The atmosphere is so loud, but the artwork and feel of the place is great. May try again when in Boulder with something else on the menu. Update: I had a thoughtful response from the owner, and I am changing my rating to 4 stars from 3 stars. Again, this staff is excellent.

This place is excellent. It's the kind of place where your waiter crouches down to talk to you and his name is Toyko and, for like two hours, you guys are (kinda) friends. They really know the beer they serve, and the beer -- most of the stuff I tried, at least -- is really excellent. In fact, I was ordering some beer for my sampler and my waiter was really nice and steered me toward some great brews. Love every IPA I tried there. I also had their signature steak sandwich, which was amazing and made from local, humanely treated cows. It was seriously strange how nice and helpful the staff here was, and it's always so pleasant when the food and the drinks and the service is equally great. Also, the place is very affordable, especially given Boulder standards. The one thing that made me pause when giving this place five stars was the pretty ridiculous no credit cards thing. This is 2014. Credit cards are the present and the future. It doesn't make much sense not to have them, and it's an inconvenience for the customer. I paid for my drinks and dinner with a check, which was definitely a lifetime first.

This was the best experience I've ever had at a brewery. I was in Boulder for a night visiting a friend after a work trip to Denver, and now that I'm back in NY I am having major Colorado beer withdrawal. The menu had an incredible list of beers that I've never seen before, which is great because I love trying new things. Even better, they give out free samples of all their varieties, no need to pay for flights to taste everything! I ended up with the Ciel Lumineux which was unlike any beer I've had before, fragrant almost like champagne, while my friend had a dark colored IPA that was also delicious. We were also given a brief tour of the brewery when I asked a question about the process. We were then informed that since it was our first time to the place, our drinks were on the house! Since we had to drive back, we unfortunately didn't get more, but I will make sure to stop by here if I ever come back. Everything about this experience was exceptional, and I wholeheartedly recommend this place

Connor W.

I'm not sure which I enjoyed more, the beer or the incredible service. The healing power of an FYIPA and a Date Night burger should not be underestimated. Restaurants like the Mountain Sun are a rare breed, and are always worth another visit.

Mark H.

Well this place is obviously awesome. A brewpub with tons of different kinds of beers (I had a very yummy IPA and a Rye-PA) and decent food (black bean soup, kinda bland, unfortunately) with the Williamsburg (i.e. Brooklyn) cast of characters? My friend and I ordered 3 beers and a cup of soup and it was 18, that's EIGHTEEN, dollars. That's insanely cheap for good craft beers. As my 4-stars say, Yay! I'm a fan.

Christian E.

What a great place... Almost 20 house made brews, whth no fewer than six were porters/stouts when I visited (the selection rotates) ( am partial to dark beers). They offer 8oz pours for only USD 2.80, a great way to try several beers and not worry about driving. (Of course, they will let you have taste samples) 16oz glasses are only USD4.75. Food is very good, don;t miss the basil bleu cheese burger. Super friendly staff, too. A couple of oddities: No sit down bar (there is a small stand up one), so less easy to chat with other patrons. Would have given five stars if they did. Also, cash only.

The food is so, so good. And the beer too, of course! Been going here for years. I love their creative brews/seasonals, always such a treat and fun. Amazing service!

Loved it! Beer was great, fries were great. We had the chicken quesadilla and the steak sandwich and they were both tasty. Service was great (we had Joshua!) even though they were packed on a Saturday night. Just note - they don't take cards! Cash only $$ so come prepared. They do have an ATM in the back, though, just in case you're a newbie.

Absolutely loved this place. Came here with a group of 10 and we all got our food and drinks quick and we were out of there in record time. I got the Java Porter and it might be my favorite beer I've ever tried. I was told it has caffeine in it as well, but it definitely didn't help with the food coma haha. The atmosphere is real hippie esque and casual. For my entree I got the Chicken asada burrito. I was expecting a chipotle sized burrito, but this huuuge sauce covered enchilda type burrito comes out. It was covered in a red hot sauce and really made the burrito taste amazing.. If you're torn between the burrito and something else.. get the burrito. Overall this place is exactly what you want in a casual sit down restaurant. The wait staff is incredibly helpful and nice and the food is amazing.

Stopped in here while brewery hopping around the area for a beer and some food. The food was awesome!!! Their nachos are maybe the best i have ever had!! All the food we had was great and they have a good beer selection. The decor was simple yet kinda cool, the staff was very good and it was a college crowd but, was wasn't filled with drunk retards. All in all it was a great experience and i cant wait to go back!!!

A great place to stumble into on a warm summers evening. I was strolling through Boulder for the first time in 30 years. I'm pretty sure I saw some of the same hippies from 30 years ago hanging out on Pearl St. I saw good reviews on Yelp for the Mountain Sun and got a random recommendation from the bike shop sales person..... good confirmation! It was busy but one of the waiters quickly greeted me, took my name for a table and offered me a beer. I told him what I like and he gave me a great recommendation for their Belgian Trippel. It was excellent. The beer was excellent. The menu has some really interesting pub grub. All of it with something unique. I chose the "Date Night Burger". It was served on a perfect roll with feta cheese and an incredible date puree. The hand cut fries were excellent. Great service, great beer, great food - that's a hat trick! Highly recommended.

Graham L.

Loved it all. I got the burrito in a bowl, which was plenty filling, cheap, and spicy. My friend's had some beers and burgers that they ranted and raved about also. The atmosphere was fun, and there were some quick community seating options if you're in a rush.

Ate their after ironman boulder. Beer is great and food is pretty good but our waitress jordyn (the Jordan who is blonde who likes to climb) is probably one of the nicest and most friendly waitresses I have ever met. I would not really go for the food but for loud fun atmosphere and jordyn being so friendly I would.

I've always had a certain affinity to Mountain Sun because it was the first restaurant I ever went to in Boulder and it was AWESOME. I've been back multiple times and have always had great beers and delicious food. The actual food is a little hippy at times, but it's definitely my style and I really enjoy it. I recently had a taster sample of their beers and was delighted by the plethora of different beers they serve. Be forewarned if you do order a sampler it is a set of 6 8oz pours... this definitely could be a bit daunting for the average boozer. The Raspberry Wheat is great starter for light drinkers, but the xxx IPA is a little more what I was looking for. My personal favorite is The Colorado Kind Ale this is a delicious beer that hits on all notes. I highly recommend anyone in the Boulder area to hit this place up. For the Denver peeps, The Vine Street Pub is close, but I still always rather go back to the original.

Poor environment. Been here twice and both times were lackluster. Loud, always too warm, don't accept CC, debit or mobile payments and we are in 2013. Staff is over stretched and non engaging. Food isn't good enough to have the ego they have.

Great outdoor counter seating for people watching. Food was delicious! Our party of three each got different entrees and were very pleased with everything. Update: 4/21/13 The food again was delicious but each time we come, I leave more and more disappointed in the service. The restaurant seems unorganized, servers are all over the place, no order. Today, after sitting down our waitress introduced herself the told us she would be bring water by since she couldn't take our drink order then. She soon returned to take drink orders, water never came. When she returned with our ordered drinks, we were told that our food order couldn't be taken because she would be yelled at for taking two orders together. 5 minutes later, she was ready to take our order. After getting our food we did not see our waitress again until we flagged her down (after a number of unsuccessful attempts) for drink refills. Not a big deal if it had not been 10 minutes without a drink eating a spicy meal. I did however notice that she had an opportunity to serve HERSELF a taster beer from the wall of taps. Glad someone's thirst was quenched at least. What a disappointment. Update: July 2013 Proprietor Kevin reached out to us via email and offered us the opportunity to be his guests to a complimentary dinner. Really appreciate how professional he was responding. unfortunately we haven't had a chance to take him up on his offer yet but plan to in the near future.

This place is phenomenal. The service and staff is some of the best I've ever experienced in my life. All of the staff seemed to love their work, and their performance reflected this. While we were waiting for our table, my friends and I just enjoyed watching the choreography of the waiters, bartenders, and busboys as they worked their tails off with smiles on their faces. The beer was excellent, with the Java Porter and the honey (ale) (i think it was an ale) were by far my favorites. I ordered a flight of 6 6oz samples, and they were all delicious. The food was pretty good, but after being so impressed by the staff and beer, I honestly wasn't even paying attention to the food...I would have had to get food poisoning to give this place only 4 stars.

Ryan W.

I've been to this place several times and have tried to convince myself that its worth the squeeze. Reasons I like it: Its a little cool, they have a decent selection of OK beers, and its easy for anyone to find something they can eat on the menu. Now, reasons I've come to dislike this place: They only take cash or check. Seriously? I see no reason for this other than tax fraud...or pure laziness. You're losing a lot of business by not accepting credit/debit cards. Get with the times. Second, this place is way too pretentious, especially SOME of their wait staff who seriously think they're the coolest people to walk the Earth. Finally, most of their servers don't know anything about the beer they're serving or how to even pronounce the names of the styles, not surprisingly. If you're going to work at a place that considers itself a brewery, you should probably know a good amount about beer. If not, please go back to your hippie tapestry filled apartment and smoke a bowl.

This has got to be one of my favorite places of all time. I almost didn't walk in because they didn't have a traditional bar area. You stand in front of the taps where all employees, cooks, cashier, wait staff, bartender, and bus people are busily working in front and around you. If you read their story, everyone does every job at the establishment. They are all friendly and work as an amazingly cohesive team, which also provides wonderful service! One staff member saw me taking a pic of the taps and told me to go behind the bar and pull my own beer and he'd take a picture. Awesome! Their beer....PHENOMENAL! The Jah Mon Ginger was amazingly refreshing and flavorful. Their Nitro Java Stout was another favorite. I tried almost all of them and I never encountered liking every single beer I tried at any microbrewery! We left to go walk around Pearl street but came back because we couldn't stay away. I'm in love with Mountain Sun. I want to marry it.

Holy hamburger goodness!!! As everyoene can make a decent burger slap cheese on it but if you are looking for a unique experience in a burger with unique tastes this is the place. So even with all of the reviews even with the hype this place did not dissapoint. First off if not from the Boulder area this is CASH ONLY, ATM in the back of restaurant. Secondly the parking is a little difficult as on Pearl St. and gets busy. As others have mentioned get there early as this place will fill up just to allow for extra time. As to the food...amazing. Started out with the French onion soup for appetizer as was hungry and didn't want to get nachos or fries. It was good nothing absolutely amazing but quality. Then with dinner I ordered a Oatmeal stout that was perfect exactly what I was expecting. Now as to the best part the burgers - I got the Date Night burger and my girl got a special burger with pears arrugala and basalmic reduction. They were both absoultely delicious. My date night was such a unique burger with goat cheese and date spread with bacon and jalapenos - I mean if that doesn't get you going then you need to check your pulse! Highly suggest this place. Also live music on Sunday nights starting at 10 pm.

BEST SERVICE. This place is super cute. Came here with a large group of friends under advisement of a co-worker. The food was really delicious, pretty much all the beer was great except for the one I ordered (champagne lady or something I don't know it was too sweet and was not really beer-like), but most of all the server was so so so helpful. He answered all my annoying questions with enthusiasm and honesty, he split the check without hesitation and made sure everyone was happy at all times without being hover-y. The portabello sandwich is fantastic and I can't wait to try their wraps and amazing sounding grilled cheeses.

Mountain Sun has a great "Boulder" atmosphere, with goofy tapestries on the walls, carpeted floors, and big wooden chairs and tables. The beer is amazing (with an amazingly high abv usually!) and while you wait for a table they often bring around samples of their delicious quesadilla. My favorite meun item: the basil blue burger. It's to die for. I always order a side of basil blue sauce to dip my fries in. Their quesadilla is also great, they have a good vegetarian ruben, and good chili. I am pretty sure everything on the meun is good. Only drawbacks: it's LOUD. Be prepared to loose your voice if you actually want to talk to the person you're with. They don't accept credit cards. They have an atm in the back that only costs $1 to draw from, so its not so bad, but it still can be a pain.

Daniel P.

This review is based upon ~25 visits, hopefully it presents a good cross section. Things you have to know: 1) They are ALWAYS BUSY, so plan accordingly 2) They do not accept cash, but there is an ATM in the back 3) Almost always extremely loud! (Most consider this a plus for atmosphere, but don't bring a date you are trying to get to know if you expect to be able to converse with them) 4) The Mountain Sun and Southern Sun have their specific, Mountain Sun way of doing things, and if you come in expecting a restaurant experience like any of the other restaurants in town, it is not that. It is its own scene and that is one of the things that makes it good, if not different. The Food: I will start with the food because it is my favorite part of this place. The spicy pollo asada burrito is my favorite, I get it "x-mas style" (red and green chili). It is always excellent, I usually fail to show up in time to account for the wait, so sometimes cannot wait the 30-60 minutes required to get a table during busy times. However, if you are willing to wait for the food, it is definitely worth it. The burgers are excellent, as is the chicken quesedilla, and the specials are always worth looking at as well. Everything is also very well priced for the amount of food you get, and the quality is great. Don't ever expect to walk in and be seated right away though, so if you are especially hungry show up early enough to get in, or try another time. The Beer: They have a constant rotating selection of beer, so the variety is a plus in and of itself. Some beers are definitely better then others, its a saying among Mountain Sun employees "friends don't let friends drink Colorado Kind" (so, might want to not). I would say if you are a beer lover you should definitely try the FY-IPA, Java Porter, and Drop Kick Irish Stout (on Nitro if its available). They also have excellent guest brews on tap, if there is anything by Russian River jump on it. The staff is extremely helpful when it comes to explaining beer, and will always give you a taste of anything you ask for, and an educated explanation. The scene at the bar can get a little bit crazy on busy nights, so if you are trying to yell at someone to order its try and identify what you want before you have to shout across 5 rows of people to order. The fact they brew so many of their own beers is awesome in my opinion though, and their beers compete with any of the best microbrewries in both Boulder and Fort Collins (such as Avery and Odell). The Servce: As addressed above, very friendly and helpful. Often they are super busy, but this is understandable, and hopefully something that you should already know before you walk in and expect dedicated, devoted service. The management does a great job of identifying good employees though, and even though I usually always see a few new faces, each of them provides the level of service I have come to associate with the Mountain Sun. One slight con, they have "seat yourself" policy, and I walked in with some friends who have not been before, and requested a specific server, Brian, who is excellent. The AGM Chris (who called himself the general manager, which is in fact not true), told me when I asked to be seated with Brian, "No, you can't do that, because we have SECTIONS". He did not offer to let us move, even though it was one of the incredibly rare not busy times, or offer an explanation of how to get a specific server in the future. However, as I mentioned in the start of this review, I have been to the Mountain Sun tons of times, and this is the only thing close to a service Snafu I have experienced, so it does not detract from my rating. Overall: 4 stars due to excellent beer variety, great food, and a cool atmosphere. Minus 1 star because it is too crowded to get in when you have a craving for their excellent food, and sometimes you just get tired of hearing "BEER, Who needs a beeeeeeeeeerr!" Absolute must try if you are new to Boulder though, and I definitely recommend it to anyone.

First visit to this mountain city, came to Mountain Sun based on reviews. I have to say they went way beyond my expectations. My friend and I split a burger, bacon & bleu to be exact, hand cut fries were a nice touch to my beer consumption. Our waitress was very helpful in our beer selections, also giving us samples of various beers served there. Which free beer is always nice, the communal tables kinda wierded me out also, however we found a two-seater so it wasn't so bad. There beer selection consists of the usual spread, light pilsners to a hearty stout. They did have a ginger beer that had a smooth mellowness when paired with the blackberry beer. Didn't try the IPA, even though it was a top seller. Also, it was the first time I had "Nitro-beer." Couldn't really tell the difference, perhaps I haven't been here long enough to figure it out. If there was a downfall, it would be bring CASH or CHECK, luckily my friend had some green or I would have been scrubbing dishes to pay off my tab. Still PINTS UP for this establishment, good food, good beer, & great atmosphere.

While walking by yesterday I noticed they just added a patio!! Tasty micro brew you can't get any where, but Mnt Sun, Southern Sun & Vine street pub. The burgers are my favorite in Boulder. Beware though this place is cash only. There is an ATM in the back by the restrooms.

Dan M.

After touring many CO breweries, I was running out of new ones to try. I found Mountain Sun and thought I would try it out. I was skeptical at first, as it looked mostly like a restaurant, and less like a brewery. But we braved it out and went up to the bar to sample some of their brews and were pleasantly surprised. One of the bartenders was quite knowledgeable about their brews, and let us sample several of them before settling on the ones we liked best. I enjoyed the Cleveland Brown, Pater Brown and Smoke Screen Porter. Also tried the Annapurna Amber and FYIPA.... both very good. I would return to this place. They are affiliated with the Vine Street Pub in downtown (near City Park), so if you want to try their brews while in downtown, head there instead.... great burgers.

IF STARBUCKS MADE BEER It would taste like Mountain Sun's Java Porter. What a nice surprise! Beer brewed with coffee can all too often end up weak and timid with just a hint of coffee aroma. Not so with the Java Porter. This beer has bold, assertive coffee flavor, nice body, strong roasted notes, and a delicate hoppy finish at the end. Honorable mention: The milk stout is also a standout.

Allison M.

We first had burgers here after a long hike and the burgers were so good! I tried the date night burger--which I have gone back for twice now--and it was an amazing combo of flavors on a perfectly cooked medium burger. I do agree with other reviewers that the buns could be improved, they are a little too soft and flavorless. The specials always sound/look so good but I haven't managed to pull myself away from the burgers yet, maybe next time. I like their beer selection and the fact that you can get free samples; this is especially nice if there is a wait so you can try beers before you sit down to order. They have pretty good beers at decent prices as well. Oh and the service has been consistently good, they are all team players and seem genuinely friendly. Nice, casual place but be warned it is cash only (there is an ATM onsite) and there is usually a wait to sit (we've experienced 10-30 minute wait but the food comes out quickly.)

Yeah its ok. Great for kids with all the games. Go for the beer and know what to expect for the food. Get the cajun seasoning for the fries or they taste like oily cardboard.

Love this place, Boulder casual with great food and beer. The entire staff was amazing and went out of their way to please. I was undecided on which beer to order, our waiter (Andrew) brought out 4 samples and was ready to bring out more (at no charge of course). The other nice part is that it is REASONABLE and unpretentious unlike some other Boulder eateries that are a bit, shall we say, full of themselves. I will definitely be going back!

Great beer, ok burgers and fries. The beer here is really good and if that was all I'd had, I'd probably return often, but I get hungry...and their burgers are...well, just OK. I've eaten 3 of their burgers and they are all solid good burgers, but not fantastic...and the fries, well they are fresh cut, but if you can't cook fresh cut fries and make em crispy and not limp as wilted lettuce, just buy the bagged ones. I know that's poor form, but really, who likes limp fries? Now the beer is really good and honestly almost makes this a 4 star place, but not quite.

Excellent service, and the staff here really know their beer. It was crowded when we arrived and while waiting for our table, one of the bartenders gave me a sampling of 4 of their beers, after questioning me extensively as to my tastes. He even drew a diagram so that I would remember which beer was which. Once at our table, service was prompt and friendly even though the place was uber crowded. I had the chicken burrito and it was delish. Really spicy and flavorful and great washed down with a local brew. Tons of options on the menu, which makes me want to go back and try them all!

Justin M.

This place feels different than a lot of restaurants you encounter. Just walking in the door, I got a different vibe. I want to say earthy, but also spacey, which is completely contradictory. Anyway... Their variety of beer is great. I love that they have a sampler you can order and they actually give you options as to what you want instead of saying "this is the sampler, take it or leave it." Another perk on the sampler is that the glasses are a decent size, you don't feel like you get 3 swigs and that's it. You get a nice feel for each beer and get enough drinks from the glass to determine what you really do and do not enjoy. The beers range from superlight and easy to superdark and roasty, so there's something for everyone. The food was a solid B. Everyone in my party enjoyed their meal. The menu seems to be bar food with an organic twist that makes the dish unique. The service setup here is a bit strange, where there's no single person as your waiter/waitress. I remember reading something on the menu about how the manager could be the cook today, a waiter tomorrow, a busboy the next day, and the manager the day after. It's a bit jarring at first, but in the end I liked it because I didn't feel like a jerk asking random waitpeople for something. They've also got loads of board games here that you can play while you wait or while you drink, which is an interesting touch that seemed pretty popular. I'm going to come here again, that's for sure. I think they have a few other locations that I'm going to check out as well (though from what I gather they're all pretty similar.)

This was our first stop on our Honeymoon of Colorado & Wyoming. We had gotten of the plane and driven from Denver, so we were starving. I had half an avocado & cheese sandwich and salad, nice and refreshing. My husband had a Colorado grass-fed beef burger, and a beer. The burger had big flavor. Beer was nice too. Service has a "team" atmosphere. The owner stopped by a few times and made some delivery.

This place is awesome. Delicious food and great service. We did have a small issue when our bill came out (we were charged for a beer we didn't order), but they apologized and fixed it without much trouble. We ordered the Boom Boom Sandwich with Mushroom soup and the Carne Chicken burrito, highly recommend both!

I have not been back to Boulder since I have been 21 so I can't review the beers, but I dream and drool about the food. The french fries with malt vinegar are so good - I don't usually enjoy mushy fries but these were delicious, especially since they were fresh. Soups and salads are good, and I dream about the avocado and cheese sandwich mostly. I cannot wait to go back.

If you want to go to a burger joint / micro brewery that is the essence of Boulder, CO, this is the place for you! It does smell a little funny (which, I've been informed, is due to all the patron-spilled alcohol)... but the beer and the burgers will wow you. This place is *packed* every night, so the service gets a little hectic sometimes and seating after 6pm will require a short wait on Thurs-Sat nights. It's well worth it though. My personal favorites, *Beer: Raspberry Wheat, *Burger: Basil Blue Cheeseburger Oh, and they have an "Express Lunch" menu if you want to do take-out during the week.

What is there left to say about Mtn Sun that hasn't been said? There's a reason you'll wait for a table for an hour- it's worth it! Service is consistently better than you would expect for a place that is reduced to standing-room-only EVERY night. The beer is incredible, and the food is above average. I recommend whatever is on the specials list- it's always amazing, and the reason it's the special is because it's always made from what they can get, fresh. It's definitely my go-to place when I ask myself where to go to dinner. Highly recommended.

A true gem of boulder, this little pub almost encompasses everything about boulder in one little building. Its a small little hippy pub that offers tons of home made craft beers, all of which i've had are amazing. They have a ton of unique beers and of course the standards (IPA, pale, amber, ect...). I probably wouldn't come here just for the bar though, because: The food is amazing. I usually get whatever's on special the day i go and haven't been disappointed. I mean its not super expensive french meals from the future, but it is probably the best bar food ever. I also like that most of the food here seems generally healthy. i believe all of the ingredients are organic if I'm not mistaken. The Staff here from what I've seen is super friendly and on top of things. The only thing that's a little wacky is this pub is CASH ONLY. I didn't realize this when i walked in and ordered and after i ate i found this out, But the staff was super accommodating for allowing me to get money for the meal. A trip to boulder wouldn't be complete without a stop in this eccentric pub.

The beer is good, the food is great, and the people here are amazing creating a fun, laid-back, welcoming vibe! So far, this is one of my favorite places in Boulder.

While I'm not happy to stumble across a spot that is cash only AND serves beer, I still managed to bust out my math skills and make a $20 bill go a lot further than I thought it would for two people. First off, raspberry IPA? Check. And it was GOOD. Sweeter than many beers, but it was refreshing after a long day. Secondly, BIG PORTIONS. As in VERY big. My veggie sandwich was loaded with lettuce, tomatoes, avocado... Mmm. Incredibly tasty, and somehow it survived a day and still tasted fabulous for breakfast. Heaven on a plate. The boy got the pulled pork sandwich special and that was equally as delicious as my non-meat meal. The pork was tender, moist, flavorful... it didn't need the bbq sauce, which in the South is a Big Deal. If your pork doesn't need sauce, you know it's incredible. Even with the sauce it was amazing, and the fries were fresh, hot, and tasted good solo or also dipped in that saucy goodness. Our server was very friendly and sweet, even offering to split a pint three ways so we could share a smaller amount and stay within our budgets. Oh, and did I mention board games?! That's right. THEY HAVE BOARD GAMES. That's an automatic win in case you didn't know. Know that this place gets packed and specials can run out. In fact, my boy got the last plate of bbq pork (making it even more amazing that it was the last plate and still tasted so good). The cash only thing is a bit of a drag, but if you don't mind the service fees, there is an ATM on site you can use. Hands down this was my favorite meal out of all the places we went to in Boulder. I'm a bit sad to have left it behind, actually...
(5)
Liz D.

They make their own beer and offer it in sizes as small as eight ounces, awesome for lunch! Plus, friendly service, good food (including veggie options), board games to play at the table, and a great location right off the Pearl St. Mall, what's not to love?

Tim M.

Pluses: It's soooo good. Sooo good. Some of the best beer around for sure. I don't think a person has been born who wouldn't love the beer and the food here. It's really what's for dinner. Minuses: 1. It's small and full of the stereotypical Boulder crowd, and can sometimes be next to impossible to get a seat. 2. They don't take credit cards. I understand they don't want to pay however-much in service fees to the stupid credit card companies that we all hate but are never-the-less all obliged to serve, but it's just a pain in the ass to have to walk back to the seedy ATM in the back and pay service fees. Call me biased but I see that as kind of disrespectful to the customer. I mean, we're still using credit cards because seriously who carries cash now adays? Might as well not make the customer have to pay for the fees. But that's just my own jaded opinion. No matter the hastle, this is the one place I'm willing to sacrifice a little comfort for. However the negatives definitely inhibit me from making the transition from the occasional customer to the dirty hippie sitting in the corner reading the newspaper.

Mountain Sun has lots of vegetarian options and a lot of things can be made vegan. Our waiter was very friendly and ran down the entire menu with me and informed me as to what was (or could be made) vegan. I was in sandwich mode, so I opted for the hummus and veggie sandwich and had avocados added. The sandwich was huge, but it was so good that I ate the entire thing. I also noticed MS has vegan 1,000 island dressing, so I may just throw that on the sandwich too next time. There are definitely some options if your vegan, a lot more if you're vegetarian. Overall we had a good experience here and we'll definitely go back - be mindful that you'll likely have to wait during lunch or dinner, this place gets super packed!

clare b.

Hmmm, I honestly thought it would be better. I'm willing to come back and give it another shot because all the food at the tables around me looked good. My daughter really liked her meal. I ordered a Cobb salad which probably wasn't the best choice. The lettuce leaves were whole, not chopped up or anything, which made it difficult to eat. The burgers and fries at other tables looked delicious. Their house-made root beer was very good. We split a piece of cake for dessert, but it was dry.

JP S.

The food was decent, and the beer options were satisfying, but the noise was unbearable. Conversation was close to impossible without yelling. We all left with headaches. After our meal, stepping out into the relative quiet of Pearl St was refreshing. I want to like this place, but until they do something about their acoustics, I won't be returning.

This was one of my favorite places on our trip through Colorado. Service was great and quick, even though it was really crowded (even though it was a Tuesday night.) We had to wait about 10 minutes for a table, so they gave us some free fries while we perused the beer menu. We got a sampler of six beers and while they were all good, the java porter was by far my favorite. I was happy there was a good selection of vegetarian food. We got the hummus of the day (green chili honey) which was amazing and completely different... but in a good way. Also got a grilled cheese with pesto, which was delicious. On top of the great food and beer, there are no tvs, so while it was pretty loud, it wasn't as obnoxious as any other bar I've been to. So, to sum up, 5+ stars for Mountain Sun.

Today I had an excellent Labor Day wrap for lunch! Tempeh, couscous, romaine lettuce and onion in a tortilla. Here are some reasons why I LOVE Mountain Sun: *Romaine lettuce in their side salad accompanied by fresh tomatoes, shredded carrot, cucumber, onion, green pepper, and the best balsamic vinegarette dressing EVER! *All the waitstaff stop by to help, so you're never waiting for 'your' server. *Amazing beer- today I had Jah-mon Ginger and whoa. It was amazing! (then again I love Ginger). *Consistently delicious food. *Although they don't accept credit cards, there is an ATM conveniently placed next to the restrooms which only charges a $1.00 ATM fee. *Beautiful artwork painted on the walls *Nice location near the pearl street mall *Reasonably priced beer!!

After writing my first review for this restaurant the owner actually sent me a message apologizing for everything and he stated that he has his staff currently working on rectifying the problems that we experienced, he then invited us to come back for a dinner on him. When we went back I got the chicken Quesadilla and my husband got the steak sandwich. I did order fries again to see if they were better and they were! I loved my quesadilla and the steak sandwich was great according to my husband. The fries actually had salt on them and they were crispier this time, which I prefer, some people may like softer fries. My husband absolutely loves their beer, so he wanted to let everyone know, so we got some to go as well. The service was great and they went out of their way to let us know that they cared about us and our opinion on the restaurant. We had a manager come to our table and apologize for our last visit and he made sure to check in on us while we were there. We had a new waitress who did very well, so I was much happier this time around. Maybe we caught them on an off day the first time, but I'm so glad the owner reached out to us, that is just excellent customer service and a good way of doing business! Try this place out!

There's something comforting about this place that I just can't quite put my finger on. I have so many fond memories of coming here with friends when I lived in Boulder. The food is delicious and the beer tastes amazing. It's a very warm, communal place and I consider it to be far more iconic to Boulder than the tourist-traps, of which this is not one.
(5)
Angelica M.

The service and staff here is undoubtedly hard-working, friendly and COOL. Like...you wish you were their friends and had their haircut/leggings. Standing at the counter taste-testing beers, you can tell they work as a team to move the process along, get patrons seated and get their food and libations to them quickly. My man and I stopped in on a Sunday around 1pm and had to wait a little bit--It was a sunny Boulder day, so everyone wanted some crisp beer. My boyfriend ordered his fave beer there Alnapurna. We ordered the special of the day, the Seitan Wrap. Although I'm a vegetarian, Seitan weirds me out. And although they were going for the BBQ chicken Seitan feel, the flavor just needed a smidgen of an extra flavor boost/zing. The salad was fresh, and I love homemade dressings. But the showstopper was the Olive-Feta Hummus! SOOOOOOO DELISH. They give you SO much and it's hard to stop eating it. mm mmm mm

One of my friends and I have decided that over the next year, we are going to visit all of the breweries and brewpubs in Colorado. Apparently there are 152. Mostly we have been focusing on breweries, as this was the first brewpub to which we have gone. It's on the south end of Pearl Street mall, which means there is an eclectic crowd, and they employ a bunch of 20-something hippies. They have really nice, attentive service, though, so I am by no means insulting them. They have a very appealing menu, with lots of veggie options, but I went for a black and blue burger. It was a nice size- normal, not some monstrosity- with hand cut fries for $1 more. They were a little limp, but again, I am a fry snob. The burger was amazing, cooked perfectly, lots of blue cheese, nice roll and good, fresh looking veggies. We also got beer sampler, where you get 6 half pints for $10.50... really a good deal if you think about it. We got a blackberry wheat beer, which I will be craving when summer rolls around. They also have a java porter which tasted like an iced coffee. We had a few other beers, all really good but slipping my mind... I had a kind of boozy, rambunctious weekend.

For good bier and good pub food, this is the place to go. I have always had fabulous service and great food. I have never had a dish I did not like. the bier here is good quality. They have a wide variety for all bier drinkers around. The staff knows about the biers and will happily help you choose a beverage for you taste. The food is quality American style food, great sandwiches and burgers. The place does not accept credit cards but there is an ATM by the restrooms. They also have games for your enjoyment. It is a wonderful place to go for a group or just two people. Never had a bad experience at this wonderful pub.

Yoyo T.

This is right around the corner from my place, but I'd come here anyways because this place is delicious. If you're looking for a good beer, excellent food and games then this is the place to be. There's usually a wait of around 20 minutes, so don't expect to get seated right away. But grab a beer and the wait will be over quick. They have a huge selection of beers, with my favorite being the Java Porter. The food also comes out fairly quickly with huge portions of fries and burger. I've tried a few things on the menu with nothing ever disappointing me. The burgers are good, the burrito is big and the desserts are delicious. Oh so good. Ok...I have to stop writing before I get a pregnant woman's craving for this place tonight.

I'm 31 years old, and I've lived in Boulder for my entire life. I know food and restaurants around here. This is absolutely the best food, the best beer, the best prices, and the best service you can hope to find around town. There's usually a really long wait before you're seated (up to an hour), but it is absolutely worth it - especially because it means you get to drink more beer :) I recommend everything. Even the veggie entrees are amazing. Eat and drink in bliss!

I was in Boulder visiting a friend and after a long day of snow shoeing in the hills we needed a GOOD meal. And Mountain Sun did not disappoint! I ordered a cheeseburger with fries and their Blackberry wheat beer. My friends ordered the "Junk Burger" which was loaded with bacon, avocado and cheese, and a "Basil Burger" with this deletable basil and blue cheese puree sauce. The verdict at the end of our silent meal (as we were all too busy shoveling into our mouths) was... "mmmmmm.....tasty MEAT". It must be the beef on Colorado, but the burger was well made with fresh veggies (lettuce, tomato and red onions) and a basket of crispy fries (extra $1 as they give you tortilla chips as a standard). The feel of the restaurant was casual, homey, and fun. The servers were attentive and helpful. Ours even offered my friend a tasting of beers when they didn't have anything she wanted immediately. He brought 4 to her that he thought she would be into, and he was right on. So if you're in Boulder and coming back from a full day on the slopes and want a good burger with even tastier beers I recommend Mountain Sun to everyone.

This place is one of my faves in Boulder. It has amazing food and an amazing Bouldery atmosphere that's great for people watching. They also brew their own beer and have an awesome selection. If you like IPA try the FYIPA there. If you like less hoppy beer go for the Quin's or Bombshell Blonde. The burgers are really good there and the special is always super good too. You can make pretty much everything there vegetarian too if you want. The veggie patty they make is tasty. The service here is excellent too. 5 stars hands down.

Great place. Arrived on a Saturday at 11:00 am as they were opening. By noon they were packed. Our waitress could not have been better. Allowed multiple tastings. As many as we wanted. Eggplant sliders were EGGCELLENT! French fries great. Burrito was huge. We are so glad we stopped here on our visit through Boulder. Beat the crowd!!!

So we walked into Mountain Sun Pub & Brewery around 5:00 on a Saturday - the place was packed. It's located just east of Pearl Street Mall. There's this little sign that instructs us to go put our name in at the bar located at the back of the pub if we want to get a table. Given that the wait at the bar was three people deep, I was sure it would take forever to get someone's attention to get our name on a list, as it didn't appear that there was a host performing this specific task. Half way to the bar, I considered for a split second just turning around and going down the street to dine elsewhere. However, prior to our arrival at Mountain Sun, we were at a local brewery and asked for recommendations on a place in Boulder that served really good burgers. More than a couple of people chimed in and said this was the place to go. So I quickly rechanneled my energy into making it toward the bar. I'm so glad I did. With about 15 feet to go, a guy behind the bar made eye contact with me and waved me on to head his way. He introduced himself as Will, and asked for my name and then took our drink order. We ordered a couple of Mountain Sun's signature brews and stood at the bar, visiting with the people working behind the bar. This place was crazy busy, the people behind the bar working at a very fast pace, but they remained very attentive, happy to answer any questions, serve up a taster, and hand out free samples of beer. I was so impressed with the service, I left a tip on the bar equivalent to the price of our two brews. Will picked it up, thanked me and put the tip into a big pitcher sitting on the bar. After waiting at the bar for 30 minutes or so (the time flew) another guy came up to me and said that our table was ready. He introduced himself as Matt, walked us to our table, and told us that if we needed anything during our time there that we should just ask him. A young woman came to the table, introduced herself - Elizabeth - and asked if we had any questions about the menu. She told us to take our time in reviewing the menu and making a decision on our order. Our burgers arrived, cooked exactly as we ordered them. As we enjoyed our burgers, Will, Matt and Elizabeth all checked in with us at some point and asked if they could get us anything. I've only written about the service because it was so extraordinarily refreshing - happy, helpful, extremely attentive people working there - every single one of them! Then BF pointed out to me a short paragraph on the front of the menu and everything made sense: "Welcome to the Mountain Sun Pub & Brewery. We believe our approach to the service industry is unique and worth noticing. Your server today may be cooking your food tomorrow, or even managing. Each employee does every job here. Our 'team system' also means that we take initiative to bus each other's tables, run food, do dishes, help you to a beer at the bar, or put your name on the wait list. As a result of this team approach, when you leave a tip, your generosity is shared among various members of the team. So feel free to ask any of us how the food is prepared, your estimated wait time, or where to find Yahtzee." Oh yeah, the food - delicious! Grass-fed beef burger, juicy and grilled just the way I like it.. Fresh LTO and pickles to top the burger. The fresh cut fries were crispy on the outside, perfectly cooked on the inside. And my new favorite local brew - Nitro Kind - a smooth finish that is unique to nitrogen beers. I will definitely be visiting Mountain Sun again not only for the great food, but for the amazing overall experience.

This little Boulder hotspot not only serves great beer and food, but is a huge bang for the buck! At 2:20p.m. there was still 25 minute wait! Their beer taster is a great deal! My husband and I shared the Brewery Taster package which is $10 for SIX selections of 8 oz drinks! Helloooo cheap! As we prefer dark and strongly flavored beers (Guiness lovers), WHAT WE LIKED: -The Java Porter is excellent - my favorite at this microbrewery - with real coffee and balanced flavors with a kick. Has a creamy finish with kind of a barley hoppy finish. - Old School Stout reminds me of Guiiness with a slightly more chocolately flavor to it. - Annapurna Amber is like Killians Red - Smooth, medium bodied, basic and simple...very nice. WHAT WAS JUST OK: - Colorado Kind Ale - definitely a hoppy ale, refreshing but not my style. Has a kick with a strong flavor! EWWW: -The Jahmon Ginger was weird! Tasted like chinese cold soup that you drink when you're sick. -Hmm, although the FYIPA is their most popular beer apparently, i can''t comment on it cuz IPA makes me cringe -this was like over the top citrusy hoppy. In terms of food, I had the Avocado and cheese sandwich- this was a refreshing Veggie sandwich - they should probabaly add sauce to it though - could use a bit more flavor. The service is great and helpful too! By the way, it's CASH ONLY. I know, weird!

Mountain Sun for life! This is hands down, my favorite place in Boulder..solo, on a date, with a group, or entertaining out of town company. The beer is not only incredibly original, it is consistently GREAT. The menu is diverse and is very accommodating to dietary specifics (gluten free, vegan) which is a HUGE part of why I support them diligently. Absolutely anyone is welcome here, and the friendly vibe permeates everything. You can tell that the staff likes each other, and the customer service is seamless. It makes me happy to spend time here. Add board games ready to be played to the mix, and you have a pretty good afternoon/night in store. If for no other reason.. stop in for a pint of their FYIPA. Killer.

I don't know why I keep coming back to mountain sun every time I'm in Boulder but I just can't seem to stay away. Maybe it's the set of six 7 oz tasters that got me hooked (fave beer so far: XXX ipa), or perhaps it's the clean and not so greasy tasting pub fare. Or maybe it's because it reminds me of McMenamins in Portland (the menu layout and design look eerily similar). Or it might be that I find a place that doesn't accept credit cards in this day and age to be quite endearing. No matter what, I'll prolly keep comin'.

We had dinner there last night and it was great. If you are looking for a lively atmosphere with excellent beer and burgers this is the place. Any beer lover will find a few different ones to enjoy and the burgers my son and I had were the best. A hard act to follow for pub food. My wife had the steak sandwich and loved the taste, but thought there was too much bread for the amount of meat (that's why it's 4 stars and not 5). Great staff - very attentive, friendly & helpful. Provided free fries while we waited for our table. We'll visit it again next time we are in Boulder.

My favorite place on earth...they actually have a Phish poster on the wall and Grateful Dead stickers with tapestries all over. They were playing Phish off of someone's iPod. All I can say is this is Heaven on Earth. You just don't get places like this in DC area or most of the east coast. Maybe in the Carolina's or up in the north eastern parts but I have looked high and low and the closest thing to "hippie" in DC would have to be Lost Dog or maybe Grog and Tankard but that is a stretch of the imagination compared to Mountain Sun. I had the Kind Ale and the vegan Tempeh Reuben and it was awesome! I have made it at home once before but this was definitely better. Great crowd, great music, beer and food. If I only I could convince my husband to move to Boulder but I may have to settle for the occasional visit.

Absolutely terrible! Service was fair and the food sucked... Looks like a cool hippie bar so I had to try it. However when I got in there it looked like the only hippie-ish people were the servers. Management looked like a bunch of death metal heads. Not my scene. Never again!

Beer: Yum! They have a huge selection on tap and lots of specials with crazy stuff on nitro. It is always an adventure in beer. I LOVE the beer with the hints of ginger and the wheats with ever changing fruits. For those who like it hoppy they have those too, I just don't love hops. Food: Try the specials! I've never been disappointed. We had a wonderful jasmine rice and black bean burrito with sweet potatoes and goat cheese topped with mango salsa. OH heaven opened up and angels sang, it was stunning. A main dish will set you back about 10.00 but the food is worth it.I do agree the fries are limp, but so many other things make up for the fries. If you have a group and are there to drink some beer grab a plate of nachos to share. Vibe: Laid back, but almost always busy. It is worth the wait. Stand at the bar and have a few free tasters as you decide on which to order. The whole staff helps out so you are never stuck waiting for your server or a refill. Even when they are busy 3 or 4 employees will stop and check on you. Overall: One of my regular favorites. Good for lunch or a snack and beer before strolling Pearl street mall. Great beer, food and people. Great for groups of 4ish not a lot of places for large groups.

Colorado Kind! Need I say more. Best handcut fries in Colorado. My last meal request would be a Junk Burger and Fries. Always a bit of a wait, but the service will knock you off your feet.

The Mountain Sun and its sibling establishments are quintessentially Colorado. Good pub food, great beers (although sometimes I question how often they clean their keg lines based on how I feel the next day). The service is usually good with an occasional lapse. The fries are great if you like them with skin and fresh out of the deep-fryer. Stout Month (February) is a great tradition. Burger & a beer night (Mondays) was also a favorite time to come in. Cash (or check) only. For the three years I lived two blocks away my checkbook had two primary entrants in the register: my landlord & Mountain Sun. Chalkboard art that you'll remember long after you leave.

Holy crap, awesome beer. My boyfriend and I did a 15 brewery tour of the area and this ended up being our favorite. Just by chance we ended up sitting down for lunch right next to the brewer.

The beer is great, but my burger contained a used band-aid from the dirty hippies in the kitchen.....They refused to replace or comp the meal, and were very rude about the incident. As you can imagine, I wasn't hungry after I found the bloody stump in my food, but at least don't charge me and buy me a beer. Put some gloves on, and take care of your patrons.

I really can't add to what everyone else has written. Just concur that the beer is awesome, they have a great selection of their own and guest pours, including a nice sample on nitro.

The Mountain Sun Pub & Brewery was my introduction to Boulder, CO. It's a very unusual brewpub, in that the place in clean, light, airy, and serves healthy food. This was completely new territory! No stale smell of beer and faint echoes of cigarette smoke...where is the grime? I ordered the avocado & cheese sandwich; it was full of vegetables but was filling and delicious in spite of that. Service was prompt & friendly; I didn't see a sour face in the place. Boulder is weird, but the weirdness made for a great brewpub.

Matt S.

If you want good craft beer in Boulder, this place does not disappoint. There is a reason a place gets 4 stars from 232 (at the time) reviews. The beers are great with Mountain Sun boasting three fermenters in the back and 15+ taps. The food is something my coworker said he used to see at Phish concerts (?), but it hit the spot! Staff are phenomenal. There is a super good vibe in this diner-like cafe.

I came here looking for a place to eat (with internet) between house hunting appointments. The waitstaff was super nice and cleared off a table that was being used by the general manager working on accounts. He was very nice and came over to chat about what I was doing in Boulder, etc. Cool guy for sure. I got myself online, read the menu and realized it was Cash Only. I must have looked too sad, because as I was packing up the manager came by and said "don't worry, I'm putting you on the don't worry about it plan. Have a seat." Intrigued I sat down and the nice waiter came by and the manager said "she's on the don't worry about it plan". Turns out, they hand you an envelope, stamped no less, with their address on it. Apparently just send them the money. Well, I'm not sure if they size you up first, or since I was moving there, they figured I was good for the money, but there are NO don't worry about it plans where I come from. I must have been living in the big bad city too long. So I ordered a delicious wheat beer (they gave me 3 different kinds to try first) and a buger with fries. The meat is grass fed from Colorado, and I could really taste the flavor. Here in California, we often get New Zealand grass fed which is decidedly one note. The beef was really really good and excellent with my local brewed beer. Delicious. Anyway, after I finished my beer, my burger, and my internet browsing. I found an ATM and promptly gave them the unused envelope, my cash for my bill and a 30% tip. Yea! I heart this place so much.

Great beer, awesome food and the friendliest servers!! If you're in Boulder, eat and drink here. You will not be disappointed! I enjoyed the raspberry wheat beer. They only take cash but an ATM is available there.

Two of us went for lunch on a Sunday at noon. The service was slow, causing our meal to take 1.5 hours for 2 burgers. The food was unremarkable - burgers (one SOB burger and one buffalo) were over cooked despite requests for medium rare, and the side salad was an uninspired pile of lettuce, three tomato slices, and two onion slices (also indistinguishable from the burger toppings...). They also messed up one order slightly, but did correct the blunder. Will not be going here again. I guess people must go just for the beer.

One of the best brewpubs I've ever entered. The food is inexpensive, and like you'd hope for in a pub. It's small, crowded, young, and on the loud side (even on a Tuesday night). I ordered a mushroom, swiss and onion burger with extra mushrooms and onions. They delivered: sloppy, savory, and delicious. Excellent burger. The corn chowder was peppery and filling. The beer list varies slightly between the menu, daily specials card, and chalkboard (which features a drawing of a woman with a long ribbon in front of a a sky filled with zeppelins). They have a full spectrum of brews, including some on nitro tap and a rotating guest beer. Most beers are $4.20 per pint, and they're excellent. Companions got buzzed off of their pale ales, and my Java Porter was one of the best I've ever had. They gave me two samples of stouts for free, and I'd highly recommend them for beer snobs. Their FYIPA has a solid "A" on beer advocate, and it's a very good brewery overall. No credit cards.

This is by far my personal most favorite place to eat in Boulder. I went to CU and live in Boulder county and have been to all the inexpensive and pricey burger joints in around. Hands down MSB is ALWAYS hit the target. And WILL satisfy any burger craving! I had the junk burger - grass fed beefy ambrosia with Swiss, sauteed shrooms and onions and the usual veggie suspects with extra pickle. This was- past tense because I absorbed it- the best burger I've had all year. Nom nom!

Great little brewery. The staff is very friendly and the beer is very tasty. I haven't eaten here yet but I plan to soon.

Last night my best friend and I went out with a mutual college friend of ours who is a professor out at UCSF/CA, and we pondered for a few days beforehand where to go. We all went to CU, and had great Boulder memories, and it had been a while since my companions had spent any significant time there, so I fled to Yelp and threw out a few choices in Boulder. Narrowed it down to 2 places, Avery Brewing on E Arapahoe and Mountain Sun on Pearl. I leaned towards the Mountain Sun because that area of Boulder is just *fun*. Also, scanning Avery's website -- no food there? Bwa? I had that mostly confirmed by my manager today, they don't seem to have food at Avery Brewing! The college prof said "there will be more women at the Mountain Sun", which was an *excellent* point and eliminated any discord. =) So off we drove to the Mountain Sun. Good karma surrounded us, because a block to the north of there is an area where it's *free* parking. Near Pearl Street? On a non-Sunday? Cha-*ching*! We went in about 7:30-ish, and the place was about a 7-8 on a 1-10 busy scale - we were put on a wait list for about 15 minutes. People everywhere, animatedly discussing things, playing Trivial Pursuit, on dates, out with their family and young babies, or just commingling. It was a "good vibe" atmosphere all over! I immediately felt relaxed and back "at home". This place is not pretentious at all; it's *friendly*. I will say though, that the waitresses are busy and get busier as the night goes on, it's like a marginally-controlled chaos storm there. We were seated at a table for 4 and brought our beers from the ale counter that we'd ordered upon entering - there are about 15 beers that they brew and you can sample any one or multiple ones, before you decide what you'd like. 2 of us started with the delicious Raspberry Wheat ale; sort of looks like White Zin. Very crisp beer, light, smooth and a very mild tartness to it that left one thirsting for more. The Prof started off with the Belgian Dip Chocolate Stout, which was extremely yummy -- people who like Guinness would *looove* this stuff, it's actually made with Belgian chocolate! 2nd round was another Raspberry Wheat for my friend, I moved onto the Annapurna Amber, a very tasty medium thickness dark gold brew, and the Prof had the Colorado Kind Ale. (You know, like kind bud. Uhmmmmmm... only in beer form. [looks around edgily for cops] And without the THC, but with other tasty substances involved ^_^) All these beers were about 6% ABV, but there are stronger ones there as well if you'd like to get buzzed more quickly. All of us were starving by now, so we ordered munchables and were not disappointed. My friend had the Junk Burger (piled with a lot of tasty things) and the Prof and I each ordered the burrito - black beans, rice, green peppers, tomato, onion, monterey jack and cheddar cheese, garnished with salsa, guacamole [maybe 2-3 tbsp, a LOT] on the side, sour cream and sprinkled with diced jalapenos. It was heavenly!! We also managed to "inherit" an Isadore Java Porter that was mistakenly poured for someone and passed it around the table. It basically tastes like a rich dark porter mixed with a few shots of rich dark coffee! The 2 tastes mingle nicely - again, probably something Guinness drinkers would love. I'd *swear* it woke us up some. Was there that much coffee in there? Only the servers know for sure. The constant chatter of background noise and bustle was halted twice by cute waitresses bellowing that it was so-and-so's birthday and what their greeting wishes were; the entire bar joined in singing Happy Birthday to 1 person, and just bellowed out "Hey Matt!" for the 2nd person. You couldn't get an entire bar to stop cold and join in wishing someone Happy Birthday in most places [there are SOME exceptions] in LoDo, or South Denver...but in Boulder it just seems like second nature. It was an *awesome* expedition and I can't wait to go back again. Read the other reviews here, especially Anthony K's from 5/27 and all his hints. They DON'T TAKE PLASTIC HERE!!! *But*, they have an ATM in the back that only charges a $1 fee - a steal considering some ATMs are up to $3-4 now. If you're in central Boulder frequently, you *may* just want to make this your preferred ATM outlet -- whether you imbibe on your way out the door or not is up to you :) 3 people escaped, with full dinner platters and about 3 beers a piece, for $45-ish before tip, if my eyes focused on the bill correctly. If the platters were about $7.50 a piece, that makes our beers about $2.50-3 a piece. Really? For beers of this quality? F**king amazing. 4.5/5 stars (if there had been no wait, a straight 5 -- but hey, weird thing about great places -- they tend to be *busy* places. Also knocked 1/4 off for the greater accessibility of the wait staff/bettter acoustics so you can actually hear your companions at their sister pub, the Vine St Pub at 17th & Vine in Denver.)

Everything about this place made my heart happy. SUPER friendly and helpful staff. Excellent, juicy burger, cooked exactly as ordered (medium rare) Heaping (small) side of tasty guac Six HUGE "samples" of fantastic beer for less than $10 Games to play at your table Free samples of beer and food given out to people who were waiting Totally reminded me of McMenamin's in Seattle, which I loved Didn't hustle us out as we finished our beers, despite the line Grilled cheese w/fries, burger with chips, guac side, cup of chili and beer sampler total: $26 The only minor inconvenience - it's cash only.

Usually I go here so I can beat my boyfriend at checkers... He gets so caught up in his beer and burger that it allows me the opportunity to cheat without him even noticing. All of a sudden, he will come back to the game and he will realize that he is losing... He will scrunch his eyes, take another swig and blame the beer... Little does he know.... Unless he reads this posting. The big community wood tables, board games and beer galore, make this a great place for a a couple different groups of people: 1) Friends (Especially out-of-town guests who care more about beer than food) 2) Family (Young families are often in there in the earlier part of dinner-time hours... So time your night accordingly 3) A date where you don't really want to or have a conversation (See, you wont even have to think of an excuse) 4) The Single Parana... A great place to meet the usually boozed up male... Or hot tom-boy girl hanging out with the guys I have never waited that long for a table, as the service is fast and the patrons are extremely hungry for some reason... hmmm, I wonder why? Other postings scream about the food, I don't feel the same way... I never find the food to be that great and I am always a little unsatisfied. On the wellness note, there are healthy sandwich options and decent vegetarian soup picks... Which temporarily keep you away from the fries. * Star one is a great urban location right on Pearl Street ** Score star two goes to MS for their sometimes free fries while you wait by the bar *** Community garden star number three is for nice large tables good for groups or meeting new friends **** Our final and last star is for having awesome brewed beer and being a guy magnet... This place can easily be a singles scene as much as a date or family scene... With groups of boys here, Mountain Sun is an ideal place to use that seductive lick of ketchup off of your lipstick that you have been practicing in the mirror lately. He, competition is tough these days, gotta differentiate yourself right?

This was one of the best meals we had all vacation. We hit many cities and this place was the stand out. I had the veggie Rubin made with Tempe and a side of french fries made in-house. We hit this place early and got the happy hour prices. We took advantage of the happy hour and tried as many local beers as we could. We tried the XXX Pale, Colorado Kind, FYIPA, Illusion Dweller IPA, and the Oatmeal Stout on my favorite nitrogen pull. I could have eaten there every night of our vacation if we stayed in Boulder.

Best beer in town. I mix the Blackberry Wheat and Java Porter together-I am that complicated-order what's not on the menu type of person. But they grin and smile and happily bring me my beer, and then another, and another, and another. I love their nachos and get major cravings for the huge pile of chips, cheese, black beans, salsa and sourcream. It's one humongus pile of goodness that's sure to leave less than 4 people stifled at how to finish the plate off. Vegetarians need not worry-there are plenty of options for veggie heads on the pub style menu including a black bean veggie burger, hummus plates and sandwiches, black bean soup, burritos, salads etc. And should you need to up the competiveness in your relationship try playing one of their games available. Currently, I am in a losing series of Connect 4-but I swear that many more Mountain Sun beers in the future will help me win!

After dinner and walking around downtown for a bit, my husband and I stopped in Mountain Sun for a drink to end the night. It was a popular choice on Saturday night because most of the tables were full. The crowd was young (mostly mid to late 20s), so we felt right at home. Service was quick and very friendly. My husband tried their amber beer which he really enjoyed. I tried one of the IPAs (unfortunately the name escapes me now - darn wine and margaritas from earlier in the night), but it was quite hoppy which doesn't bother me at all. If you are not a fan of hoppy beer, I wouldn't recommend the IPA I had, but I am fine with a hoppy beer. When I saw the handwritten bill and $5.50, I assumed that meant each beer was $5.50 which wouldn't be unreasonable in my book. Boy was I wrong! Our two beers total were $5.50. Mountain Sun is a great casual place to enjoy some beers and hang out. Again, I'm glad we listened to the recommendation of some of my husband's co-workers because we really enjoyed Mountain Sun.

eating here and not being able to drink their amazing beers because it is during the work day sucks! love the food .. never had a bad item. Fish and chips are excellent. person with me had complained about not being able to find decent F&Cs in CO and these changed their mind.

Great lunch and dinner menu, with lots of options. Delicious, healthy pub food, and decent service. Always great beers on tap. I love the nacho's and grilled cheese with tomatoes, pesto, and avocados. It gets pretty busy on weekend nights, but the appreciates you waiting, and sometimes hands out some food to keep your grumbling stomach from making too much noise. All in all, great food for the price you pay, always a place i bring out of town visitors.

Calvin F.

Went here on the recommendation of a local. The location is great, and it was super-busy. You have to go up to the bar and put your name on the list if you want a table, but you can start ordering beers while you're waiting, and they'll even attach the tab to your table when it arrives. The beer was actually rather disappointing. It was decent, sure, but nothing to write home about, especially from someplace in Boulder that bills itself as a brewery. The food was excellent, though (I had a special spicy veggie wrap with a lot of flavor), and the service was excellent; everybody was super-nice and attentive, even in spite of the place being really crowded. I could go with either a three or four on this one. Overall, it seemed like a good local hangout, but maybe not the first place to check out in town.

Meg W.

Have held up the bar here numerous times! Love the beers, the atmosphere and the friendly girls/guys behind the bar. Can only comment on the beer here and I love how you can sample each beer before committing to a pint or two. Their IPA is great, the chocolately stout and the raspberry wheat, which I usually drink in that order. Haven't tried the food here as usually I'm a happy camper after said pints (stout is like a meal in itself, isn't it?), but I've heard its good.

Carlton N.

Great beer and very friendly service. This was my second trip and I really enjoyed the experience this time (not that the last time was bad). On this visit, I tried a beer flight and put my fate in the hand's of my waitress - she did such a good job of selecting interesting beers that go together and matched what I was looking for. While the beers and service are great, the food is just OK. I would categorize it as high-end pub food with a heavy representation of vegetarian fare. Everything I was served was quality, but it was not adventurous or daring.

Shaun D.

Great beer (love the nitro options), great food, and awesome service! We've eaten here twice already since our one week stint in Boulder and love it. Try any of their chili + corn bread, Christmas style burrito, and the date night burger. Also the vegan Ruben was bangin'!

Dave S.

The beer says it all! Across the board they have tons of beers that are top notch. I may have tried more samples then actually beers I ordered. The problem started when I couldn't decide what beer to get. The food was very good as well. When you sit back and have a drink and food in front of you, look around and watch the whole staff smile, laugh, and goof around and realize this place is fun!

Anthony K.

Okay, the Mountain Sun has amazing food and beer. Here are some things to keep in mind to get the most out of the dining experience: 1) Take a look at the specials on the chalk board right when you walk in. They are creative and very tasty. 2) Go to the bar (at the back) to put your name on the wait list. Anyone at the bar will be glad to put you on the list. 3) Although this place is often crowded, don't be intimidated when it comes to choosing a beer. The staff has always been more than happy to let me take my time tasting beers to find the one I want before ordering a pint. 4) Every staff member can, and is expected to, work every role in the place, from chef to bar tender to server, so they are extremely knowledgeable about the menu and what's on tap. Don't hesitate to ask them for a recommendation! 5) Remember it's cash only. But, they do have an ATM in the back that only charges $1 service fee. Have fun!

A burger from Mountain Sun would be my last meal. I would give it 5 stars but it's so noisy in there from lack of sound proofing that sometimes it's difficult to hold a conversation. Seems like an easy enough fix and maybe someone will read this and do something about the noise. It would be perfect then. Get the Junk with cheddar and fries, you have to get the fries!

Devon P.

I took out of town family to Mountain Sun and everyone is super friendly. They offer free Avery beer tasting while you wait which was nice. I ordered the build your own grilled cheese which was very affordable. They were a little disorganized, the fries came out 10 minutes before the sandwiches so I ate all my fries before I got the rest of my food and my cousin's fries were cold by the time her food arrived. My husband had the burrito and it was tasty and reasonably priced. We would go back.

People love this place and I do not know why. The beer is basically good homebrew -- it is often not brewed to completion and is not filtered. The result is a hurting gut and head the following day (or even the same night on some occasions). The only food I will order is a grilled cheese or rarely, a burger (the fries are disgusting so order it with chips). I have two positive things to say about the Mountain Sun: 1) Good atmosphere (though small and quickly gets crowded) and 2) Nice, helpful employees for the most part. If you are a beer-lover and doing the beer tour thing, I highly recommend one of Boulder's other amazing breweries (particularly Avery, Boulder Beer, and Twisted Pine). If you want a chill and affordable place to relax while you're downtown (and it is not uber-crowded), stop in and have a beer but I wouldn't stay for two.

The room was great, the service stellar, and the attitude of the place is laid back and inviting. We showed up at 8:30 on a Thursday night, and there was a 30-minute wait. It wasn't a big deal, as we were able to have a pint at the bar and take a look at the tanks, as they make many of the beers that they offer in-house. When we were able to get a seat, I wasn't sure what route to take on the beer selection, so the server was kind enough to bring me a few samples based upon the direction that I was leaning. I settled on the Cleveland Brown, and at $11/pitcher I thought it was a steal, as it was a really tasty microbrew. We split a basket of fries as an appetizer, and I ordered the Black Bean Burger. My friend ordered the Grilled Cheese with sauteed mushrooms and onions. Both sandwiches were accompanied by chips, but substitutions are an option no problem. Credit Cards are not accepted, so be sure to bring cash. The black bean burger was tasty, but it was messy! I might not get it again next time for this reason, but all in all I definitely don't regret the order. I'm really glad that I stumbled upon Mountain Sun. If you don't mind a bit of a wait, it's worth it. Check it out. You'll be glad that you did.

Stopped in for lunch and a pitcher of beer. I'm a bit of a beer geek and the FYIPA did not disappoint. The food and service were both excellent. Had a steak sandwich that was on special, it was wonderfully spicy with just the right amount of heat. Thanks to Annie our wonderful server for a fantastic experience. My only negative is around the policy not to accept credit cards. A bit of a hassle.

Mountain sun has amazing burgers and beer. The staff is fast, friendly and well in tune with their customers. They brew their bear on site and I got an awesome tour from the manager. Their menu has just about anything you could ask for from a pub - including vegetarian options. The portions were large, taste shows a clear dedication to quality ingredients. The fries are unreal and thankfully not salted so you can put on what you want. I ate there with my 3 year old son and 74 year old father and both were very happy with their food! The beer is cheap and has real flavor. Bottom line: Great service, food & beer and a LOW cost.

Sherri K.

I love this place. I feel really lucky that I got to re-introduce myself to the Pearl Street Mall via this brewery. The crowd was a delightful mix of students, locals, tourists and all around beer lovers. I am not usually a fan of the dark, sandwich-in-a-glass beer, but the selection was so vast and there were too many flavors not to at least try. The chocolate was surprisingly exceptional. Lucky for me to be with such a connoisseur of the heavy beers. Although it was packed, the hostess went out of her way to find us a table and as loud as it was, the cozy 2-tops were perfect for intimate conversations and light flirting. Not that I ever flirt. The nachos were fantastic, and good thing because big beers + no food = Bad Sherri. The cheese was melty and good, and it was a heaping mound of pure late-night goodness. Our server was cool, and helpful in making choices and keeping us abreast of really important things like when the kitchen was closing and/or when HH was ending. Oh yeah they have a 4 hour HH. Bonus. I can't wait to get back~

Great Boulder experience, highly recommended. I had dinner here with family back in June 2009. This was one of my best dining experiences in Boulder this year. Sorry my review is a little light, I ate/drank at Mountain Sun five months ago and am only now getting around to yelping it. Better late than never, though.

Order the tasting flight of beers. You'll experience an adventure & a buzz. The CU sandwich was awesome. The veg chili was tasty too. The place was packed at 2 pm, so I can just imagine the crowd at prime time. The wait staff sport smiles. They gave free beer samples while we waited for a table & then served us extra French fries just because they had an abundance and were hot. Great place if you can get a table.

Jenna C.

On a weekend trip in Boulder, we stumbled into this spot for lunch. It was packed, so we waited at the standup bar and had a few beers. Really awesome beer - unique types and flavors. I had a raspberry beer which I thoroughly enjoyed. We were seated after about 15 minutes, and we ordered sandwiches for lunch. My pesto grilled cheese sandwich really hit the spot. My boyfriend had some variety of a chicken sandwich - also good. The food was great, the beer was better, and it was good value for the money spent. Also right on Pearl Street - a plus for a tourist who is walking the Pearl Street strip. I would recommend to tourists and locals alike!

This lovely pub is worth 5 stars in terms of their staff and service which is top-notch, homey, welcoming, and warm. Their beer is worth a million stars in my opinion. They have every range and style of beer imaginable and they rotate a lot! I'm giving 4 stars only because they are a cash-only place and that bugs me a bit. The first time I went in here I was a bit overwhelmed because the place is always busy and there are no seats at the bar. The bartender was very kind and offered me tasters of almost everything. Instead of me having to ask him to try some, he just kept bringing me tasters of brews he thought I would like based off the types of beers I told him I enjoyed. After trying about 8 beers, I finally settled on a fantastic summer saison. Since he knew it was my first time here, he gave me my beer for free! Amazing hospitality! Sunday nights they have live bands, and the place just has this great, inviting feeling. The color and decÃ³r is hip and very fitting to Boulder's personality. I heard their sister pubs in south Boulder and Denver are amazing as well. I can't wait to try them out!

We went three times in two days! Best of both worlds for me and husband -- very tasty, healthy-ish, and inexpensive food for me, and outstanding beers for him. Dunno what they put in their chicken but it's awesome compared to boring dry stuff at most places. Great vibe and we loved the board games.

You have redeemed yourself, Over, and over, and over again, it has taken me a while to update this review, because we wanted to dine here quite a few more times.

My husband and I drove up to Boulder to hang out on our day off. We wandered around the pearl st. mall and asked a few people for recommendations and Mountain Sun kept being mentioned. It has been a while but I do remember we both loved our food. We had the Junk burger, with no mushrooms for me. Of course we had their fries and we even asked for some garlic mayo on the side to dip. We split a beer sampler of 6 beers. It included Quinns Golden Ale, Isadores Java Porter, XXX Pale Ale, some sort of Lemongrass spearmint beer that was a limited time offereing. I really liked Quinns Golden Ale. I was excited to try the Raspberry Wheat, but they were all out. I plan on trying their new Denver location. I am already looking forward to the fries and Raspbery Wheat.

We stopped by Mountain Sun for a bite to eat on the way to Avery brewing. Got to hang out with the brewer, Nate who was very Kind to take time and talk about their beer and the business and show me around the brewery. Nate was so generous he even offered to buy us a round. I had a F.Y.I.P.A and Basil Blue Cheeseburger and what a sublime pairing that is. The Vietnamese sandwich was delicious too! Hat tip to everyone at Mountain Sun Brewery. Cant' wait to go back to Boulder!

Gretchen W.

This review holds true for both the Mountain Sun and Southern Sun, so you will see it posted at both. What the Mountain/Southern Sun gets right the others just don't seem to get: just be authentic, unassuming and unpretentious. Be consistent, be friendly, and don't try to upsell or push appetizers or desserts. The Suns hit the mark on quality, and they don't seem to try to do anything more. And why would they, when they're succeeding at what they do best. I believe the quality of the beer and food and the friendliness of the staff and commitment of the management team shines through to reflect the spontaneous community ethic advertised in the pub decor homage to touring jam bands like the Grateful Dead (whose following was, by all reports, a friendly and communal atmosphere). Many restaurant chains and "concepts" try to imitate this subtle feeling through decor and advertising, but they're just imitating. The Suns are the authentic item, the real deal. 5 stars for the beer: easily the best beers I've had at any microbrewery in the State of Colorado; far surpassing those of any brewery in the Boulder area. The waitstaff have been, in my experience, extremely knowledgeable and helpful when it comes to picking out the right beer to suit my tastes for the evening. They know a lot about what's on tap, and how it compares to beers of similar class made by other breweries small and large. Beer is a fine art at the Mountain Sun! It's worth your time and liver to sample as many as you can. 5 stars for the nachos: served piping hot with real cheese, whole black beans and excellent salsa. A whole order is a perfect filling split between 4 when paired with a pitcher. 4 stars overall for the food: it's very consistent and always good. It's so much better than any other pub fare in Boulder. Places like the Walnut Brewery try to be "classier" but end up falling on their faces when it comes to consistency. Conner O'Neil's tries to have that Irish Pub atmosphere but feels fake and the food is rarely of the caliber to stand up to their standard imported beers. The Suns have figured out how to make consistently good food and are sticking with it. I recommend coming in for the specials, such as fish&chips night. 3 stars for the atmosphere -- pure Boulder -- crowded, noisy, and people hanging around for a long time over books and games. The interior hand-painted and hand-chalked art is wonderful in a summer concert jam band traveler sort of way. People who frequent the Suns are friendly types, usually kind and polite, not jostling and rude and creepy as it can be at similarly crowded places (The Med). While it's loud, it's not frat-boy loud nor sports-bar loud --it's just loud because everyone is conversing and trying to hear/be heard. And I'm really glad there are no TVs. Whoever needs an electronic feed should seek elsewhere. Again, the Suns focus on doing what they do best, not trying to be like everyone else. 3 stars for the service: I've been coming to the Mountain Sun at odd intervals throughout the year for 5 years, and the service is consistently friendly every time. It has also recently improved to be more prompt, even during the busy times. I do have some friends who've received poor/unfriendly service, however, and due to that simply refuse to join me at the Mountain Sun. This is sad because part of the appeal of the Mountain Sun is that it's a friendly place to hang out with friends and share a pitcher. So, while my experience is always good, I am concerned about my friends. I think this is an area that could still use some investigation, but the improvement in the past year is noteworthy. Many reviewers complain that the Suns are cash-only. I know that there's a very high cost involved with using credit cards at a business--a significant percentage of each transaction. Usually, this cost is passed onto the customer in higher prices. I appreciate that the Suns are keeping customer costs down at the expense of a tiny inconvenience. Really folks, is it so hard to stop at your bank's ATM for cash on the way, or to use the ATM in each Sun location?

Nachos are of legend status here. Really good its nearly a fourteener they are piled so high. They use real cheese and not that liquid queso crap. Also had a salad, which was decent. I would have preferred something more tossed instead of big chunks of veggies on top of lettuce. But, they were fresh veggies...I'll give them that. -1 point for not taking credit cards. +2 points for giving me a self-addressed stamped envelope and told me to just send them a check in the mail instead of paying the outrageous ATM fee. They almost deserve 5 stars for that ridiculously high level of customer service.

I'm still not exactly sure what having beer "on nitrogen" means or if it makes things better, but that option is available here. I enjoyed their beverages thoroughly. The cheese fries were a welcome side dish as well to accompany beer consumption. Played a few games of Connect 4. Was disappointed that they didn't have a deck of Uno cards though. Articles cut out from The Onion graced the walls of the men's bathroom. However, a bathing hippie graced the sink as well. But its Boulder, after all, so that was to be expected...

A pretty chill place that we started the night off at for my friend's birthday. They had a good selection of beer and a decent bar menu. The whole vibe of the place was pretty chill and fun. My friend brought a boardgame for us to place while we drank our first rounds. The java beer was pretty intense. The manager/guy in charge and our waitress was pretty awesome, because my friend's party kept on growing and he totally hooked us up with another table and was super accomodating. The entire bar sang happy birthday to my friend too! Definitely a fun place to taste a whole lot of beers.

Great beer, food and service! Just a fun, good food place to eat and hang with friends. Everything we orderd was great from burgers, nachos to veggie chilli. Cash only.

I hope my star-rating doesn't confuse anyone. I'm a huge fan of Mountain Sun for what they offer- amazing micro brews and decent food for cheap. I however dislike sun due to the rude waitstaff and frequently pretentious clientele. I find this to be contradictory- don't pretentious people like good service? Maybe they are regulars or something and actually get good service. I don't know. In short, go for the great beer (4 stars), cheap and decent food (3 stars) and don't expect much from the employees. Also expect to wait for at least an hour on Thursday, Friday and Saturday nights.

Seriously LOUD and seriously good beer. Try the Dropkick Stout mixed with Blackberry Wheat or the XXX Ale. Damn good dark beers. Service was slow but it was Memorial Day so I cut them some slack. Vegetarian chili is tasty and the pulled pork special had a strong mustard flavor but was delicious. The table next to us ordered a burger that wasn't cooked exactly how the diner wanted it, and the manager did not hesitate to recook another burger for him and comp it. Nicely done. And I have to give a shout out to big man behind the bar. You know who you are--big, muscular dude with the beard. Woo wee.

This place is "like" TOTALLY Boulder. For all you Dead Heads--they have lots of Grateful Dead memorabilia. The beer is brewed on-site. They also have homemade root beer (with no high fructose corn syrup). This is what I had and it was really delicious. This is a fun place with inexpensive and GOOD food located on Pearl Street Mall. I feel like I'm in a time warp from the sixties!

Cheap, cash only and good beer. This is the same as the Vine Street Pub in Denver.

Absolutely great food. It's a brewery for sure, but specialized in wonderful creations. Good veggie options. Their burgers are stellar. Get in on this... if you are drinking try the FYIPA.

Great microbrews and chill atmosphere. After a day of hiking and chowing down at another place down the street we were looking for a local spot to taste where the locals go. It's cash only, but I heard that they'll give you an envelope with a stamp to send cash back if you don't have it on you. Not sure if that's true, but seriously friendly way of doing business. They have music on Sundays, which we didn't get a chance to experience, but got to see them rearrange the room by physically lifting people already in chairs and moving them. It was quite a scene.

Ten years ago I was a regular at Mountain Sun, which to my mind reflects all the best that Boulder has to offer. I'm happy to report that nothing essential has changed in the past 10 years, this place continues to be the gastronomical beating heart of Boulder. Everything here is good, and beware: when you order a full plate of the nachos, a mountain of cheese and chips will arrive at your table.

So I really wanted to be vindictive and give the place a two-star rating at most after my experience yesterday. I took a long shower this morning though and mulled over what exactly the Mountain Sun is and how I should actually approach this review. Certain establishments should be rated on different scales; you couldn't possibly, or at least fairly, compare Red Robin to a place like L'atelier right? With that same thought in mind, I can't reasonably compare my experience at the Mountain Sun with my subsequent experience at The Boulder Cafe. Went to happy hour right around 4pm on Friday with my buddy Jon and were really baffled by the service we received. One of the servers impatiently asked if we knew what we wanted just as we began to consult the menu. Not quick enough on the draw, she left to fetch us some water, as we sat trying to decide what kind of beer we wanted. Here's the thing: the water never came. Server 1 saunters off and up comes server 2. I ask if they have any happy hour food specials to which she kind of chuckles and says no. Well, that's fine, we'll just get some beer for now. Server 2 goes off for a while, server 1 comes back and is slightly baffled that we don't have waters yet. I am baffled as well, even more so when she disappears again never to return with water. Server 2 eventually comes with our beer, leaving Jon and I to wonder what the hell is going on. In retrospect, I don't think anything was going on. I realize I have failed to convey the weird, ambiguous attitude we received from our servers; other yelpers seem to interpret this as "laid back" and "casual" service, which I can understand now. What I think happens here is a "Tragedy of the Commons" in a restaurant setting, the servers are continuously rotating tables so there is little incentive to try and be somewhat friendly to patrons. But enough of that. The beer here is great, brewed in house, and reasonably priced. I assume the burgers and vegetarian chili are tasty as well, since this is a sister pub to the Southern Sun (a place I have frequented more than a few times). Perhaps my friend and I just arrived at the wrong time, as this place definitely seems more hoppin' in the latter hours of the night. I will certainly give the Mountain Sun another try, albeit with my chin up and a stiff upper lip to boot.

Top notch experience at Mountain Sun Pub & Brewery. The people here are super nice. The beer we had was delicious. We are hop-heads, and they had more than a few choices to fullfill that need. We had a hard time deciding what to eat, as everything on the menu sounded so delicious. I had the burito with chicken - mouth watering, savory, spicy red chili sauce, absolutely delicious. My husband had the fish and chips and he was all smiles. It was really good. All around, this place is a must go to if you like tasty beer and food. Hopefully we'll head home with a growler of the FYIPA, or the Resinous Rye. (Their Growlers look like giant mason jars!)

Laid back, hippy-esque brewpub. The beer was good, and the sampler is generous, I definitely recommend it. The staff was incredibly helpful in selecting and recommending beers. Food-wise, they have a veggie selection, and the hummus sandwich is good, but not great. Apparently the staff is on a total rotation, so you might have different waiters throughout your meal. This just adds to the laid-back atmosphere, and along with the various board games to choose from, makes you feel welcome and not rushed.

aha...just what the Mountain Sun on Pearl in Boulder needs...another Yelp review. Such a variety of perceptions...I simply must throw in my 2 cents worth, for whatever it's worth....the first correct answer wins a prize!! It's the plethora of choices of grilled cheese that have made me love this place. I have not tried the grilled cheese at the other location(s) just here. Always good. Verrry cheap. Nice to play a board game here, and I like the friendly service. When it is crowded at dinner time, it is sometimes a little daunting to make one's way through the gauntlet of the entire length of the restaurant to put one's name on a waiting list. But the upside of this process is that sometimes you can meet a new friend or two while making the pilgrim's progress up to the bar to get on the wait list. Still, it's a relief to successfully happen in during an uncrowded time. This is rare. Such is success in the restaurant world. I love you, Mountain Sun, because grilled cheese sandwiches with real cheese, on whole grain fresh bread, at a reasonable price, are just what I need sometimes, along with your tasty root beer that I enjoy and your many beers 'most everyone else enjoys, and your beautiful absence of TV, which I appreciate greatly.

Sarah S.

I'd heard my bro & sis-in-law rave about this place -- it's true. They served a free burrito at the bar while we waited. The avocado veg sandwich was really tasty and their red wine was decent. Run here if you like beer (I don't). They've got a great selection of their own brews and a few "visiting" brews.

Mitchell F.

Immediately after finishing our dinner at Mountain Sun's sister restaurant, Southern Sun (see that review as well), we met a friend here for another pint. After getting a taste of the great brew earlier in the night, we had to get some more. While Southern Sun was getting quiet when we left, Mountain Sun was just picking up when we arrived. A local band was setting up, and the place was packed. ...Maybe a little TOO packed. We had a hard time having much of a conversation, and the crowd around the bar made getting another beer quite a challenge. I think this place is definitely worth a second try, however, and the setting might have been perfect if we were just looking to groove to a great local band.

Danielle K.

This used to be one of my fav stops on Pearl Street. ( I left boulder about a year ago). The pitchers are cheap, the beer is SOOOO good, and for a bar I really like the food. I love the raspberry beer ( a theme in my brewery visits). It even has a nice pink hue to it which i found interesting. I also really like the chocolate stout... but only to taste. I don't think I could drink a whole glass. Same with the espresso stout. I love how they basically will let you sample 3 or 4 beers for free ( i think they are supposed to charge you, but I was never charged). I always got the blackbean veggie burger (so Boulder) and I was never disappointed. I love it. The price is right and it goes great with beer! Perfect! Then you can stay, chill, listen to some music, chat with your friends and drink more beer! Other than the fact that it is always crowded and its VERY loud, if you get a table, keep it and enjoy yourself. Great local vibe and food and drinks.

JT S.

Tho we don't live in Boulder we visit friends here sometimes. Tho the Mountain Sun is not our favorite place to eat, and it is always so crowded and you have to navigate through the crowds to the back to get on the waiting list in order to get seated, we still like to eat here because of good beer, good music, and good cheap grub. I've gotta say something about what Sarah M. mentioned...the people who eat at Mountain Sun are generally outdoorsy super health nuts who have probably just been out mountain biking, mountain climbing, jogging, or one of their other triathlete pursuits. This is probably why Sarah did not like the smell of real, active, athletic humans who stop in to get a bite to eat before going home to shower. We've always had casual and laid-back but passable service. No place pleases everyone, but I'd rather that a place smell like humans than chemical disinfectants. Sterility is what I loathe. 'nuff said.

Jonathan K.

I like this place and I like their beer. This is the place you go when you want dinner to revolve more around drinking, than eating. Don't get me wrong they have good burgers and sandwiches as well, but their beer is king here. Four things the Mountain Sun should do though: 1. Tell the table wiper person to water-down the damn Chlorox before wiping all the tables before lunch. Seriously, ever wonder what the Chlorox factory smells like? Step inside their doors between the hours of 11:30 am and 1 pm. It smells like someone shot Chlorox out of a water canon into the restaurant. 2. Stop putting an entire industrial-sized-can of black beans on your nachos! Look...black beans are good and I like them but having nearly 400 of the little suckers on your nachos is not cool! 3. Have live music more than one night a week. 4. Whoever keeps stealing the damn Connect Four pieces out of the box on the game shelf, please put them back! Kinda hard to play Connect Four when you have 7 black pieces and 9 red ones. Know what happens??? No one can win the game. Perhaps that is the point.

I am writing off my first experience here as a one-time bad day because since then I have had the most exceptional service I think I've ever encountered since moving here. Last night, we were handed free nitro samples at the front while waiting for our table, then we ordered a pitcher, and then arrived three more full sample glasses of another beer we had been debating. We all loved the Pearl Street Porter pitcher and the Rye-PA samples equally. FYI that Rye-PA is going away soon, they only made a few kegs of it, darn. Since my vegetarian little brother is in town, I knew he would dig the menu and the beer-baked tempeh reuben made him a happy camper. The tempeh was a different, darker color than when I tried it before, and it tasted much better. My husband inhaled the pulled pork-ham-bacon sandwich but for the first time maybe in my entire life, I finished my burger before him. It was topped with a basil-blue cheese puree and freaking delicious. I would have sucked up that sauce with a straw, however there wasn't any left on my plate because I had already dipped all my fries in it. We chased down every hand-cut salty crispy fry from all three plates. During this rapid food shoveling, we had numerous friendly servers stopping by our table every few minutes asking if we needed anything, refilling our waters, making sure the food was good...similar to our last experience at Vine Street Pub. This was what I pictured in my head on my first visit to Boulder...an idyllic pub filled with happy high-on-life people, tasty fresh inexpensive food and a long list of delicious beers. The only complaint is that they don't serve wings like Vine Street and Southern Sun, because they are the best wings I've ever had. PS you can get cheap pints during happy hour 4-6pm.

Predictable heady chill brewpub in Boulder. Their beer was excellent. On their menu it says something about how there are no "jobs" at Mountain Sun, that everyone that works there does every job, from cooking to waiting tables to cleaning. This results in disjointed service, which usually benefits you - there's several people waiting on you and they're not all doing the best job of keeping track of what you order, so you get free beer pretty frequently. They're all nice kids, though. As for the food, it's alright. I see this place has plenty of other reviews that probably go into the food issue in more depth than I will - but for the record, whoever described the vegetarian black bean burger as "so Boulder" is a fucking idiot. You, madam, is a dumb bitch. Overall, their food is so-so. There's a major gap between quality of beer versus quality of food. Solid college town brewpub.

Matt Q.

I almost walked away because of a wait list but a waiter stopped me and quickly made a table available (that's service). A ordered a quesadilla the turned out to be 8 inches wide and generous portions of sour cream, salsa and guacamole, and regretted having to polish off a whole basket of fries. The beer selection was excellent. The atmosphere lively and on the hippie side but not obnoxiously so. It's ideal location on Pearl Street means that afterward there is always a street performer for a cheap show. It is cash only with no ATM on site, however if you can't pay they give you a "Karma Envelope" with the bill and you can mail in. Okay a little obnoxious and I don't believe in Karma but I imagine most people pay out in reciprocation of trust.

This review is a bit late as I went there a few weeks ago for some brews and grub after a day of hiking and went back again just this past weekend. As before it was a full house and very loud. I found it hard to hear and be heard by the person in front of me but the beer is good. Had the java porter and it was smooth and rich and full of good chocolate flavor. I ordered the half order of nachos after being warned how large it was and it was good typical pub food. Being the weekend I parked in the parking structure across the street for free. Not sure if I'd go back. Like the beer but don't care for the noise.

Every few months I crave a delicious, juicy burger and this is where I go. It's a spiritual experience for me. I have to close my eyes and savor the delicious moment (and thank that cow.) I'm also quite smitten with their chicken burrito. A perfect blend of textures and flavors. Atmosphere-wise, I like that it's friendly and lively in here. This has the downside of sometimes being too loud for my mood. The wait-staff is friendly, and come to think of it, they seem to always be in a good mood. They are team-oriented so you may have several people attending to you, which (usually) makes for good service. And though they are a brewery, I am not much of a drinker, so can't say much about their beer, but I know their selection is loved by many.

Jenny L.

This place has amazing food for a restaurant, not to mention a pub! Everything I've ever eaten here has been amazing. They also have a million different things on tap and will let you taste whatever you like. And the wait staff is really friendly. If it weren't for the following downsides, I would probably want to come here every day: It gets pretty loud in there, and it can get really packed, even on a weeknight. And while I admit that those qualities have deterred me a couple times, I still love this place.

Emily C.

Mountain sun has great beer and a great atmosphere. The food is decent, nothing spectacular but is what I would expect from a little brewery. We got there early enough to get a table, but it can get very packed later at night. Our table was too big for us, so they asked us to move. It was no problem for us, but they comped some of our beer anyway! Mountain Sun is for sure worth checking out.

I really like it here. Great location and does a wonderful job of epitomizing Boulder. Unfortunately it's often very busy, but it says a lot about it's reputation and popularity. The only complaint I have about the place is that it does not accept credit cards. However, there is an ATM provided on site. I have yet to try their beer but I know it's a great hit and one of the many reasons people frequent the pub. The vibe is incredible. Welcoming, homey, earthy, happy, casual, and (as odd as it may sound) accepting. The restaurant has a humble approach to waitressing (the story is described on the menu). It's a very shared job here. If a waitress notices that a table is in need, she or he will assist that table. Another personal favorite about this place is the trivial pursuit cards they have on hand. They provide a few games and entrainment pieces for their customers. I come here with my parents when they visit at school and we love it here.

Jimie D.

Mountain Sun has delicious food, great atmosphere, very friendly employees, and free samples of beer upon request. Sometimes it is impossible to get a table because this place is so busy. I have put my name on the wait-list and waited at the bar for an hour or more. The beer they brew here is superb and the food is great. Some of my favorite things have been the build your own grilled cheese, and bratwurst. I dislike their salsa - however, I hear many love it.

I loved everything about this place. The food was tasty, the beer was unique and delicious (with plenty of choices), and the servers were the friendliest I've ever encountered. They even handed out free quesadilla slices to people waiting for tables to become available. If you're ever in Boulder you have to come here.

Awesome selection of veggie bar food- I had the tempeh reuben, but it was a tough choice...there were so many other awesome looking options: veggie chili, veggie burritos, wraps, quesadillas, burgers, sandwiches, etc. All under $10. Great beer too, and friendly service. The beers were almost $4 a pint which seems a bit steep to me...and the Yahtzee had no dice and no score cards, just the cups. Now what kind of Yahtzee is that?? Oh, I wish they had outdoor seating...

This restaurant's atmosphere is wonderful; fun and lively. They decorate the walls with Grateful Dead posters, rugs from South America(?) and sculptures. The placed is loud and lively. There were lots of people here for a friendly good time. Mountain Sun Pub and Brew even have a shelf for board games. Good times with friends are found here. Their staff are very helpful. They stop by very often. In fact, I say that because three different individuals came and checked with our group to ensure everything is OK. Now, let talk about the food. Attention mushroom lovers, go straight for the Boom Boom Sandwich. Its a tasty portabello with zesty balsamic sauce. The bread is unique crunchy and perfectly warm. The Gooney Bird Turkey Sandwich is fine. Not the best, but still good. Their fries are extra crispy. If you're a fan of crispy fries, then definitely get the fries. But you're probably here for the beer, and the beer does not disappoint. Awesome selection, and each one of these the waiter took his time to explain their complexities. Hoppy or light? Strong dark taste? He'll tell each of them to you. I went for their sampler. Ginger flavor in beer? Wow, interesting in deed. One thing that they miss in today's modern, high tech, fast pace world. What do you mean cash only? I have trouble imagining that money only works in the form of paper!

Scott G.

Wife and I had lunch at Mtn. Sun and we are now fans. She had the basil blue cheeseburger and absolutely loved it! Said it was a 10 of 10s. I had the blackened chicken sandwich and really enjoyed it (perhaps an 8 out of 10). Noticed many in the Pub were ordering burgers in our general area of seating. Service was outstanding-servers constantly checking to see if our drinks were full and that we were happy with the food prep. Place was packed. Its a very noisy place but the food and servers made the lunch worth it all. Would describe ambiance as a bit like the 60s and 70s-not great but ok. Worth the money....cannot speak to the alcoholic drinks as we had unsweetened raspberry ice teas and we loved those. Biggest negative: They do not accept credit cards so bring cash....or a check if its a local patron.

Thurein P.

The home of my favorite beers in Boulder. Their FYI IPA & Java Porter rival any brew I've ever had the good fortune of drinking. The food is excellent to decent but very well priced. I would suggest the basil blue cheese burger or the enormous mound of nachos. Unfortunately the delicious chicken wings that are available at the more family-oriented sister establishment, the Southern Sun, are not available here. The nights to come to the Mountain Sun are Tuesdays and Sundays. On Tuesdays, one can enjoy happy hour priced pints ($2.25!) of their fantastic brews all night long if you're wearing one of their T-shirts/apparel. Don't have a T-shirt ? Well, buy one! They have great designs on them and you'll get a free beer with that purchase! T-shirt Tuesdays do tend to be very crowded and loud, and you may rub shoulders with some of the hippier patrons. For a more relaxing evening, Sunday nights feature live local music (tends towards folk/blue grass) and a less rowdy crowd. Although there are always people to dance with.

This is my first review as a Boulderite. I used to live here for many years, but I moved to the Bay Area to get my graduate degree in food snobbery. Now I'm back and I'm ready to tell it like it is. Went on a Friday night and had to wait about 20 minutes for a 2 top, which was expected. This place is somewhat legendary in Boulder and is very popular, with waits typical all week long (the south Boulder location is even worse). The crowd was mostly college-aged, with a few 30s and up sprinkled in. Had a pint of the Quinns Golden ale, which is one of their lighter beers - very delicious. While waiting for our table at the bar, a server passed around some quesadilla slices. Nice touch. Once seated, the wife and I decided to split a burger with fries, plus I ordered a grilled cheese while she got a cup of chili. They serve grass-fed beef there, which is appreciated, but we really miss the buffalo burgers that used to be available in the olden days. I gotta say, the burger was cooked perfectly medium-rare, and the grilled cheese was pretty damn good. Washed down with another beer, and I was pretty happy. On the downside, the chili was just "eh," and the fries were too soggy for my taste, although we did eat them all. For a Colorado burger joint, this place has everything you could want, from the jam-band concert posters on the wall to the tattooed wait staff to the top-notch microbrews. I only knocked off a star for the gooey fries and the weak chili. Service was fantastic, although the place was a bit loud.

Michelle S.

No reservations, but they are very friendly and will help you at the bar to get a table ASAP. We tried some beers while we were up there and I found my beer of the night, the ginger beer. I could smell the ginger every time I was about to take a sip, so yum! Being a non-meat eater, I ordered the black bean burger and oh, have I been dreaming about it ever since. The b/f got the regular hamburger and he loved every bit of it. Prices are reasonable and the staff is very friendly. We were even asked if it were ok for them to seat a quiet baby next to us (yes, the parents were with it). If I am in the area again, this will be a must on my list of places to visit.

Love this place! Super friendly and helpful staff. They will encourage you to have samples of all of their brews, which by the way are delicious. Very reasonably priced and the food was great. Would give 4 1/2 stars, with the only deduction being they do not take debit/credit cards.

Andrea G.

My husband had the Junk Burger and I had a regular cheeseburger. The burgers were tasty, but not quite as seasoned/juicy as I was expecting. The hand cut fries were a treat. They have a pretty good selection of beers, and the staff is all very friendly. We arrived about 5:30 on Thursday and the wait was about 20 minutes, but you're able to grab a beer while you wait, and the servers walk around with samples of the appetizers. Will definitely be returning in the future.
(4)
Elaine E.

Didn't get to sample any of their food, but it looked pretty damn good. I was there strictly for the beer. I had some kind of speciality brew - lemongrass something something (super helpful, huh?) - that was down right amazing. We didn't stay long (we were touring 4 other breweries) but one of the servers agreed to give us a tour even though they were absolutely hopping. Of course, that was after they did their staff bar slam (not sure what the shot was...) Would definitely go back to try the food. Was also slightly alarmed at the smell of BO around me. I think it was just some of the trustafarians but not something that I'd like to encounter while eating.

Trixie D.

I went here on a beautiful Friday afternoon and was able to get a table right away. My husband and I came to grab a beer and an appetizer, but decided to have lunch when we saw that they had vegetarian green chili on the menu. I started the meal out with a Colorado Kind Pale Ale on nitro. It was a bit of a wait (nitro takes longer to our and the keg happened to run out while mine was being poured). It was pretty good, but I would suggest getting a regular one on CO2. As far as food, I went with a garden burger topped with Swiss, mushrooms, and onions. I upgraded to fries ($1 up charge). My husband got the vegetarian burrito smothered with green chili - this was by far better than my meal, but kinda heavy for lunch. I had an Oaklord Oatmeal Stout next, which was divine. I'm not sure if I would wait an hour for a table since there isn't really a good place to wait, but I would definitely return the next time I am in Boulder.

Mountain Sun is like Southern Sun, but worse in several ways: first, it is more cramped, which means the loud music and the loud talk make this place especially susceptible to...noise.....; second, the service here is spottier than at Southern Sun. Why this is, I'm not exactly sure....but the difference was pretty stark; third, it is on Pearl Street which makes parking pretty obnoxious; and fourth and finally, they played some of the worst prog. rock/stoner rock I've ever heard in my life there the last time I was there. Dissonance just isn't cool at a restaurant, especially for 2 hours. Anyway, go to Southern Sun instead...better service, easier to get to, and less annoying in the noise department. From what I could tell, the food and beer were naturally the same: good and excellent respectively.

Donald H.

This place is so cool! I went in with a few people during a business trip, mainly looking for some good beer, and was extremely happy we ended up here. I had an amber brew and two blondes which were all pretty good. The blondes reminded me of some fine Belgian beers, closely resembling Delirium Tremins. I had a Vietnamese sandwich on Ciabatta which was different in a good way. Overall, great place for a beer and food.

A friend of mine was driving his newly purchased '81 Westfalia from SLC to Pennsylvania and stopped through Denver on the way. I love when friends come into town. JDubbs and I usually have a routine of doing laundry and catching up. I know. Weird. After laundry and a thorough butt kicking at the pinball machines at 3 Kings, I suggested we go up to Red Rocks.....of course. But JDubbs said he'd never been to Boulder. So off we went at 3pm to soak in the Boulder 'culture.' We walked up and down Pearl Street when I remembered I hadn't been in the Mountain Sun brewery in years. So, we stopped in for the start of our Boulder beer tour. And...................4 hours later still standing at the bar......... JDubbs and I tried the Colorado Kind Ale (10 stars!!) and the IPA and some other beers which I can't quite remember right now because we had a lot of beer. We were even privy to try to Creeper ( I think because, well, I had a fantastic buzz happening) which was a mix of the Kind and the IPA. The bar staff passed around some quesadilla to sample and even gave JDubbs and me a grilled cheese on the house. And it was cheap to boot!!! And what would top off a trip to Boulder but a deep philosophical discussion about Religion at the bar. That and the fact that JDubbs hit on a lesbian his Boulder experience was complete.

This is the best beer pub in Boulder and rivals anything in any other state I have been in. These guys brew everything in the back of the house and I am quite fond of the Colorado Kind and any Porter or Stout they have on tap (and if they have it on Nitro you absolutely must order whatever it is)! They have a late night happy hour which is a steal. The five stars are for the beer cuz the food is just so so. But seriously their beer turns anything you are eating into gold. Their beer has the Midas Touch.

I have been going to this pub since its inception. They have opened another south of town with very consistent results. Since moving from Boulder I have been hard pressed to find similarly tasty, hoppy brew (and nachos that equal theirs). In my search for tasty, quality, hoppy stuff, a close second in quality, color and flavor in my opinion has been the Standing Stone Brewery in Ashland, Oregon. At the Mountain Sun, I have to say I love the nachos. A small order is more like a "large medium." Their fearless use of black beans and fresh salsa has made me an addict. Staff: their baseline service is decent but can be inconsistent in terms of how fast they round on you. On the other hand, they rotate the staff in all positions which gives the place more of a family business vibe. Beer selection: HOPPY, flavorful, broad spectrum within the hoppy bandwidth... Fact is, because I don't visit Boulder frequently enough I typically crawl into a pitcher of the nitro Kind and/or Triple X and am quite satisfied.

This is my favorite restaurant in Boulder. Order a Junk Burger and an FYIPA and shut the hell up about the hippy service and cash only. Welcome to Boulder. The real Boulder.

Delicious beer of all sorts, great food, fun atmosphere (colorful decor instead of TVs). Juicy, ethically raised burgers, super fresh salads, and an interesting assortment of other foods for both vegetarians and meat-eaters. If the green chili stew is available, order it! Count on waiting for a table if you show up in the evening, as it's nearly always packed. Don't go if you are claustrophobic or if you are looking for peace and quiet. Also, be forewarned that they don't accept credit cards (although they have an ATM on site). The service is consistently excellent, friendly and attentive without seeming forced. This place makes you feel welcome.

My first restaurant visit in this fine city of Boulder CO! Blackened chicken sandwich was delicious and it was def. worth the extra buck for french fries. They have a Monday lunch special where a beer is only 2 bucks with an entree. Will be back for sure. Love the vibe and funny names for the beer and food. I see many nights here in my future... Just remember, they only take cash.

Rating: 1 Star * Although this is a huge favorite of locals here, remember that I am only rating this on how gluten free friendly and tasty a restaurant is. The staff is uneducated and not familiar with gluten at all. Even when the manager comes out to try and help, the only thing that I can end up getting is a very crappy salad and a burger (which I will say is tasty) wrapped in lettuce. I would skip this place for sure if you are looking for a nice GF meal. More gluten-free reviews at: glutenfreeboulder.com or find us on Facebook!

Place was PACKED!! Went on a Friday around 6. We actually waited for about an hour, which normally I wouldn't do. Although we had beers while we were waiting and I didn't want to go somewhere else after that. We were given our choice of free appetizer for waiting so long, and that was a great gesture. The service was excellent! The waiter was friendly, knowledgeable about the beer selection and attentive. All pluses. :) Good food, good fun! Oh, and the pricing was right as well! Cash or local check only, though. So be prepared for that!

GREAT BEER! Decent food. The only bad thing about this place are the kids eating here. IMAGINE.. the beer is so good here there is almost a line of students buying the beer by the gallon (growler) haha! IF you're a beer fan, you must come! Get the tasters! Very friendly staff and you don't have to deal with the attitude I get from VINE street pub off of 17th in Denver. Go Boulder!!

We happened to run into Mountain Sun after a big hike in the beautiful Rocky Mountain National Park. The restaurant we wanted to go was reserved by a private party the whole night, oh well...Mountain Sun is so vibrant with lots of young and hippie crowds. The decor is simple yet pleasant with lots of boutique textiles. The beers were so good! A lot of them are brewed in the pub. The falafel was just yum even for someone like me who is not a big fan. My Turkey cheese melt sandwich was also delicious. We had a full stomach after all, and happy...Boulder is great!

Went for lunch today, had an Annapura Amber beer, cup of Black Bean Chili and the Black Bean Burger for lunch today. All were very tasty. A bit confused about service for we had four different people at our table together. And we had to ask for the check to be totaled, and then weren't sure what to do with it when it was. We took it to them, didn't take away from the food nor the experience, just a bit questionable.

I love this place. This was the the first place I ate when I moved to Boulder. Chill atmosphere, great food and good beer. What more could you ask for? Some of the beer is available on nitro, which makes the beer extra smooth. I always enjoy coming to this place. Located on famous Pearl Street.

Oh, the Mountain Sun (Pub and Brewery). What a great place to enjoy the mountains and the sun. Oh, and the hippies. Obviously--you are still in Boulder--so their presence will be KNOWN. Not that I eat burgers, but I hear the burgers hear leave little to the imagination. And the beer--just plain spectacular! (though I don't drink beer either). BUT I know peeps that come for miles! You will leave the Mountain Sun with a smile. You wont leave for a while. BUT when you do....

Mountain Sun = Second-best burgers in Boulder. That's saying a lot for a hippie joint. Sure, they've got a tempeh Reuben, as one might expect, and plenty of other hippie fare (and a perhaps surprising amount of Mexican food options), but they still know how to grill a piece of meat (all-natural, hormone-free beef, of course). Their house-made beers are great as well, and I've never had a bad meal, be it a happy hour taco, the burger, a salad, pasta or even said tempeh Reuben. Complaints: They don't have a TV. Not only that, they refuse to have a TV. Rather pretentious. I'm not looking to be inundated with televisions, but sometimes I just like to go to a neighborhood pub, sip a beer and zone out watching the tube. But overall, this is a minor complaint. I come here for food and to be with my friends, and I'll go to the Lazy Dog if I want to watch TV while I drink. Oh, another complaint. Get a freakin' credit card machine. It's 2007. Mountain Sun's cool factor in a nutshell: During the great blizzard of 2003, when the entire city had shut down, when police were ticketing people for driving their cars, I walked down Pearl Street (I lived downtown then) to see if anything was open. Everything was quiet and closed--except the Mountain Sun. The place was rocking. Not even a blizzard can stop these people. Rock on, Mountain Sun.

We ended up at both mountain sun and southern sun multiple times over the course of a week long visit. The food is plentiful and good, the beer is excellent and the employees seem to love their job, which makes me happy. The place is relaxed and there is always a young crowd hanging out, talking, laughing and playing games they discovered in the large stack of them on the bookshelf in the corner. I tend to gravitate toward browns and amber ales and both of those were excellent here.

Nothing against these guys. I drove about 30 minutes to eat lunch there due to the high ranking. I don't get it. It's a college town pub, basic decent food, kind of a short beer list but adequate. I'd eat there again if I happened to be in the neighborhood, but it isn't worth going out of you way.

I've been here once, and I dont know if its a California thing, but happy hour at this place is really a HAPPY HOUR. I came with some friends, and 6 beers cost a little under $20! They offer some beers from nitrous, so they have the same foam consistency as guiness. The carbonation seems "smaller", and its sooo good. I would recommend this place to anyone to in boulder. Also, the wait staff is pretty rockin. We only came to grab a few drinks, but the waitress we has scored us some free fries. Pretty sweet deal.

Stopped in for some lunch on Saturday. Laid back atmosphere, friendly staff. Tried the following: - Monterey Chicken with guacamole, Jack cheese, lettuce, tomato, onion on Multi-Grain Oat w/ a side of tortilla chips ($8). It was ok. Probably should've gone with the baguette option instead of sandwiched between 2 slices of bread. - Basil Blue Cheeseburger with blue cheese crumbles and basil blended into a dressing, then poured on the burger and garnished with a fresh basil leaf ($7.75 + $1 to sub chips w/ fries). Ordered this medium well but it came out medium rare. The meat was pink and mushy. Sent it back. Fortunately the waiter was cool about it. Burger was redelivered as specified. The basil blue cheese dressing was too runny. It went everywhere, so I didn't get much on my burger. It also made my bun soggy. The bun is supposedly whole wheat, but it looked like white bread to me. Maybe they use white whole wheat flour? The fries were nice and hot. They seemed fresh cut and I liked that they left the skin on. - Junk Burger with bacon, Pepper Jack cheese, sautÃ©ed mushrooms and onions, roasted garlic mayo ($8.95). Had high hopes for this burger but it kind of just tasted like your average bacon cheeseburger. Overall, the food was mediocre. There wasn't anything particularly unique about the flavors. However, it's a nice, laid back place to come in and chill. The restrooms were a little bit gross though. Could've used a good clean up. Note that they are cash only.

OK, just keep in mind this is based from 100+ visits. The place rocks -- fantastic beer, brewed in-house, cheap fantastic beer, nice vibe, even a family vibe if you want to bring kidz, music at times (Sunday nights), the Southern Sun also, hippies, solid pub food, great happy hour prices on beer. A great place for dinner or an extended 4-6 hour hang with a rotating cast of friends dropping by. friendly and loose. Used to live in Boulder and this may be what I miss most in NYC. Sometimes there's a big wait but what are you going to do about that?? Go to Southern Sun in South Boulder or better yet go stuff your face at the Olive Garden in Louisville, if there is one there.

I was wandering around Pearl with one of my friends, and neither of us are from Boulder, so we decided to stop in. Their cheeseburgers are really good, not too big, not too small, cooked perfectly...I can't wait to go back for their beer, which I hear great things about! Happy hour sounds fantastic, I must add it to my Happy Hour list (not yet on Yelp).

Vacationing in CO, visiting family and having had a somewhat traumatic day (rear-ended in rental car, followed by an unrelated visit to the ER in Longmont with one of husbands family members) we decided to spend a little time on Pearl St. After a couple hours of browsing the stores and letting the kids run loose we thought we'd settle in for dinner and beer at the Mountain Sun. A word of caution, if you are allergic to Patchouli - or hippies for that matter - don't come here. ;-) Thankfully, living in the SF Bay Area, it felt like a little slice of home. F*ckin' hippies. The place was nice and loud - which was great since the kids were getting pretty cranky having waited at least 45 minutes for a table. The food was pretty good - I had a really fresh and delicious spinach salad - the kids had burgers and fries which were perfect. The beer, for the most part, was fantastic. We were really happy with our selections, with the exception of the Arctic Wheat, some bizarre minty concoction (i know this won some sort of medal - but folks - some flavors just don't belong in beer). The FY IPA was outstanding (OUTSTANDING!!!!!!) and was definitely the evening's winner. The service was slow and scattered (which I attribute to the fact that they were incredibly busy) - but the servers were really nice. We seemed to have several people waiting on us, but none really seemed to know what was going on - so when we got our last round of beer twice and the server realized someone had already brought it to us, she put the fresh beers on the table, looked at our still half-full glasses and said "Do you want to keep them (free of charge)?" We had probably already had way too much beer for one evening, but when someone offers you free FY IPA it would be a crime to say no. Ladies and gentlemen, that's what cabs are for.

Finally, a Boulder restaurant that actually exceeds it's appearance (which admittedly is not hard to do in this particular case). Thought we were in trouble at first since in order to get a table you need to go to the busy bar area in the back and give your name to one of several servers in the hopes that you'll actually get one. Surprisingly this chaotic arrangement worked well as we were seated reasonably quickly and in order as far as I could tell. As an added bonus the servers would periodically come through with samples of their appetizers. As one should expect the beer is the real reason for coming here and it does not disappoint. Seriously this is some of the best beer in Colorado which is not a compliment I dole out lightly. Food was pretty much the standard pub fare you would expect with some Boulder flair. Service was good too. Servers were genuinely nice, not the hipster d-bag variety that could easily infiltrate an establishment like this. I will admit being "cash only" is a bit inconvenient and they could use a proper bar; however, these two minor knocks are not enough to take away a whole star. While I am aware this is not exactly fine dining Mountain Sun executes the brewpub blueprint perfectly, phenomenal beer, more than adequate food, and a genuinely cool atmosphere.

Great place! My brother and I shortly after 5pm on a Saturday because I paid attention to some prior reviews that said this place fills up and unless you want to be standing room only, you better arrive fairly early. It was nearly full but the two of us were seated at a 4-top. This was great because some establishments won't seat two people at a 4-top, especially if seating is at a premium, so kudos to Mountain Sun for not being 4-top snobs! In spite of the fairly small space and large crowd, this place really does have a cool and laid back vibe. I told the waitress that this was our first time and that we REALLY LIKE BEER, but were unsure of what to order. I asked if we could have a tasting and suggested that she could bring us some of her favorites. Clearly this gal REALLY LIKES BEER too because she brought us 8 tastings. What I really liked, wast that she took the time to write down the name of each beer on coasters so that we could keep track of what we were tasting. I'm not so good with recalling the names (especially after several "tastes") so having them written down was incredibly helpful. I ordered the Date Night burger and OMG......oh so yummy! My brother ordered a bacon cheeseburger and enjoyed his as well. I like home style fries, but the only minor issue was that they were a tad limp and not crunchy which I prefer. I feel bad even bringing this up, but this is an overall review so I wanted to share the whole experience...the good and the limp! :) Their beer is stellar and the service outstanding. We didn't want to be rude to others who were waiting for a table but we were really enjoying the experience and didn't want to be rushed. Our waitress didn't make us feel rushed in the slightest so thank you for that. I will most definitely be back! After Mountain Sun, we were off to Avery....

popped in here with my family in tow while visiting family in boulder. we had two kids in tow (2 yr old and 6 yr old) that had been out and about at the farmer's market, so you know they were a little wound up and crazy. anyway, the service was great; attentive and accommodating. the food was what i'd expect from a pub, so i have no complaints there. for me, this sort of place is all about basic comfort food, good service, and a great pour. i was not disappointed the least. as for the beer, i'm a bit of a hop head. i found the "kind ale" to be excellent and the xxx pale ale to be good. i was actually really surprised at the porter. even as a hop head i would highly recommend their porter. great stuff. i'll definitely be back while i'm in town. maybe even check out one of their other spots. the beer got me, but their really nice service is what's going to get me to come back.

The burger fell apart while I was eating it, juices running down my hands, pieces of bun and lettuce and cheese cascading to the plate. Crispy fries accompanied these fallen morsels as a sort of burger & fries salad. The beer was dark and good. The waiter was a hippie who was having ... a really good time. The bill was like $20 for the two of us. When I manage to get back to Boulder, I'll be back here. No question.

I was on a search for a pint glass for my collection...My friend and I sat down in a booth only to be greeted by the worst smell of BO ever. The whole place smelt like it. Is this normal, or we lucky enough to go on the one day it permeated everything? We were going to stick it out so I could at least get a beer and a glass. I asked the server if they sold them, and apparently they only sell plain glasses, why would I want a plain glass? She kept rushing us to make a decision of what to drink, and kept repeating, do you just want water, can I just bring you water? Jeez, fine yes, we'll get water. We got up and left as soon as she walked away. Horrible service, horrible smell, and no pint glasses.

For what it is, a cash-only burger joint with microbrewery and hippies, ultra-friendly waitstaff and campy feel, Mountain Sun totally succeeds. As David Z. mentioned below, the fries are excellent - skin on medium cut non-crispy yet satisfyingly tasty with vinegar. Burgers are also great too. Some other items that are good on the menu are: quesadillas (with or without chicken) soups (whatever kind, they're all consistently good - NOT CHILI) chicken sandwiches and, of course, beer. I like the browns and the wheats are also good too.

Eric H.

A SOLID place for some beer and grub! If you want some straightforward (and cheap) food and some great beer while in the neighborhood of the Pearl Street shopping mecca, this is your place. Specials on the weeknights (things like burger and beer for $7), and a 4pm- 6pm happy hour every day. The service is efficient (and communal): You need salsa? Flag down pretty much anyone that works there and they'll be happy to hook you up. Be sure to bring cash 'cause that's all they take; there is an ATM in the back; see it on your way to the brewing tanks (and bathrooms). Yeah, so give a beer sampler a try (they've got almost 20 beers brewed in-house on any given day), but I can personally vouch for the Thunderhead Stout and their imperial IPA (which I think is called I & IPA). And like some other folks said, they've got boardgames waiting in the wings, free for all to play; find an open table and spend an afternoon (after you rock some running/biking/skiing, of course)..

While in Denver, I took a day trip up to boulder to check out a few places. I stopped in this place, and if you like good beer, it's a must. 18 TAPS! The people working there were so nice and helpful. They what ask, what type of beers I normally liked, then proceeded to place 3 samples of what they felt I would enjoy. I probably sampled 8 or 9 beers. The 2 I finally ended up getting, and recommend, are the Retro Pale Ale and the Chocolate Thunder Stout (I think that's what it was called). If you're in Boulder, stop by, you will not be disappointed

Well, this is a little bit scary. I live just over a block from Mountain Sun now. That means that when I get home just after four in the afternoon, I have to make a choice between walking to Mountain Sun and having a couple of happy hour priced pints or going to the gym. Anyone care to hazard a guess about how many times I've made it to the gym in the last two weeks? In the imaginary perfect town in my mind, Mountain Sun occupies a prime location on Main Street. Fortunately, in my real life, Mountain Sun occupies a prime location on Pearl Street and I actually get to go there. So, good beer, good food, excellent service (why doesn't anyone else copy their everyone is in charge of every table in the place attitude?), and great atmosphere. Negatives? I'm stretching a bit here to come up with something. It can get a bit loud. But it's a bar, what are you expecting?

Want to take a peak into a spot where real Boulderites go for a good time? Check out Mountain Sun or its sister Southern Sun. It's a combo microbrewery and restaurant- sure to treat you to a good time!The vast variety of award winning micro brews will not disappoint, the atmosphere is loud and fun, you can bring board games to your table to entertain yourself (yay!), the servers are attentive, friendly and knowledgeable, the food is tasty and the prices are right!! Check out their specials (I loved taco night) and you will be in for an old fashion tasty deal!

Without a doubt-- the BEST BAR IN BOULDER. I've lived in town for over 5 years now, and there is no place like this. A perfect 10 in every category. Basically a Grateful Dead version of Cheers. The food is-- as far as pub-style cuisine goes-- top notch. I'd go as far as to say that the Cheddar Junk Burger is the best burger I've ever had in a restaurant (but make sure to have plenty of napkins on hand). The service is fast and friendly. The beer is unmatched-- The Colorado Kind is one of my 3 favorite beers in the world. Every Sunday night, they bring in great live music. If you go, ask for Pat, Kat, or Chris (or Danny, if he's still around)-- they're the best. One small anecdote: When I first turned 21, I knew this was where I wanted to have my first legal pint. So I went with my roommate, got to the bar, and ordered a beer. As the bartender was bringing it over to me, my friend mentioned that it was my 21st birthday that day, and that she was serving me my first legal beer. Immediately, she turned around and poured the beer out. She then proceeded to fill up about 10 tasting glasses. As I sampled their many beers, she asked me what I liked about each of them, and what I didn't like. When I was finished, she brought back five more, from which she narrowed down my personal tastes even more. After a few rounds of honing in, she proclaimed that she'd found the perfect beer for me. She returned to the taps, poured me an Annapurna Amber, and told me it was "on the house". Four years later, and it's still one of my favorite beers. Now THAT is how you serve a new customer. I cannot say enough about this bar.

Being from the Northwest, this place definitely had a McMenamin's vibe about it: with hippy decor and a similar menu. What they had that McMenamin's does not, was several gold medal winning beers. I really liked the Saison I tried. The wait staff were very friendly. The only downside was that the place was so popular that there was quite a wait for a table, so this place wouldn't work as a place to go grab a pint.

Awesome microbrewery on Pearl Street. We got a long bench table to sit on for the 10 of us. We ordered nachos, fries, different sampling of there beer (they brew it in the back). It was great, laid back and chill.

This place is a fun college town pub! It's a conscious organization that brews their own brews and offers free range and organically grown food. Their rasberry wheat ale was good, their guinness-like stout fair, their wine selection not so hot (sort of for the wine in a box crowd), and they didn't offer any pear cider (I hope they do some day...), but outside of those few things, the atmosphere was fun, friendly, and ready to rock out. I enjoyed Mountain Sun.

I love love love this place and come here regularly for awesome burgers and ohhhhhhh the beer...they are constantly switching up their selection of in-house brews and have a great selection of guest microbrews as well. Their blackberry wheat and FYIPA are my favorites but they make amazing stouts/porters as well and stout month (in february) is a must if you are a local! Their girl scout stout is the best stout I have ever had, or maybe the coconut cream, it's a toss up. As others have stated, their house beers are unfiltered which I think makes it that much more delicious but I know some people tend to dislike, so beware. There are plenty of filtered guest beers if you insist. I have always gotten good service here, and yes, if it is dinnertime especially on a weekend you are going to have to wait, but big deal - you're going to have to wait anywhere you go on pearl street on a weekend!!! get over it, I say, or make a reservation somewhere way nicer and more expensive. this is a cheapish burger/beer pub, after all, not frasca. there is a great selection of vegan and vegetarian options here as well. and yes, there are a lot of hippies! so if you don't like guys with beards or the smell of patchouli, be forewarned. they have a fun selection of board games to play while you wait for your food, and the best fries and burgers in boulder IMO. the servers are very friendly and helpful in my experience and this makes the crowded waiting area easier to deal with, I think, as in they are very accommodating and pleasant even when, say, you might be blocking the entrance to the bar while waiting for your beer. they also are good about circulating appetizers while you are waiting, and I have gotten more than one free beer here for various assorted reasons. overall, this is a very laid-back, chill place with great food and great beer, and it's not a place to go if you expect highbrow attitudes, and maybe even if you expect others to wear deoderant :) I will agree with others that this place is very quintessentially "boulder" and if you are down with that vibe, check it out. if you want to be asked "sparkling or still" and not have to wait for your table at all, go somewhere else. I actually live closer to southern sun and it is essentially the same, and often does not have as long as a wait as mountain sun, if you are really concerned about that.

During my 10 years in Boulder, Mountain Sun was my hangout. The restaurant is small with a few bigger tables and some booths. There is nothing like the vibe you get after a day or skiing or whatever, then walking into Mountain Sun for some Kind Ales and a Grilled Cheese. It feels like everyone in the place probably did something damn cool that day as well. TIPS: be ready to wait and stand by the bar for a while until your table is ready, service is not great...but it's worth it.

My favorite place to eat and have a great microbrew in Boulder. Not everything on the menu is to die for, but it doesn't matter because burgers are so amazing!!! They have a wide selection of ales and a down to earth atmosphere. I sadly moved away from Boulder but I make sure I stop by at least twice every time I visit because once just simply isn't enough.

I really would have given them 5 stars, but when I ordered my pepper jack burger with "fries"....they gave me a burger with pepper jack and "rice." I'm not kidding. And I DO NOT have a funny sounding accent either. They put rice on my burger. A little airheaded, but once they fixed the burger, it was great, and so was the beers I copiously consumed after I ordered my rice burger.

A couple other things you should know: they do not accept credit cards and they have board-type games to play while you eat and hangout..

For the quality of the beer, food and for the low prices, this place is unbeatable for a pint, a (free range) burger and superb pub fries. Of course, it's hardly unpopular, so at peak hours there will be a wait (at the bar).

Some places just take you back to a time when life wasn't so chain-oriented and dining out experiences felt authentic. This is the ultimate grad student hang out in Boulder and the beer is arguably the best in the city. (I drink anything off of the nitro tap). Coming from Chicago, I had this gleeful moment of reverse sticker shock during happy hour....and the quality of the happy hour beers. The burgers are fine, but come here for the beer and hanging out aspect. Southern Sun is also great, and considerably larger...

Amazing!!! You are missing out if you do not stop at this place when you are in Boulder. This experience is for those looking for amazing beer (and I am a wine drinker, but the tripel and the porter made me a fan!) amazing service (let's just say this- the place is packed, the bar is full of tables waiting, but you quickly have beer tastings in your hand and free French fries while you wait and as soon as you are completely fine with tasting beer as long as needed (5 minutes) you are called to sit at your table. Wow! Fine tuning is what is happening with the staff here- they all are completely integrated and working on amazing customer service. As others have mentioned, take some cash, or hit up the ATM ($1.00- right outside), if you don't have either of those the "karma card" will get you a meal (you mail your payment for your food in a self-stamped envelope when you get home- right??? Amazing!! - love!!). Ok - lets just add that the cost of this food is almost unbelievable- very affordable. We had the junk burger, quesadilla, french fries (add the cheese, stop counting calories- worth it!), and a porter for dessert!

Mountain Sun encompasses everything granola and homeyish that I think of when I think of Boulder. The menu is eclectic, lots of sandwiches, salads, and burgers. And the beer menu was long, so long that they let you get free samples of beers of your choosing (aka free sample pregame). Our table ordered the nachos as an appetizer and a delicious pile of chips, cheese, and salsa was on our table in no time. If you don't want to see the person sitting across from you, order this nacho mountain. For dinner I chose the Monterey Chicken sandwich mainly because it had guac on it. It was good but nothing to rave about. I stole some fries from my friend mid-dinner and they were fantastic. Apparently her Date-Night burger with goat cheese was fantastic as well. I would definitely recommend Mountain Sun to anyone looking for a casual cheeseburger and beer type of dinner that won't break the bank.

Go Here. I have never felt so dang welcome in a place as much as I did at my time at Mountain Sun Pub & Brewery. Talk about amazing customer service. Before I get too far into details, the absolute coolest thing: Karma checks. WHAT? What is this do you ask? They are cash only and have an ATM on site that only charges $1 BUTTTT... If you don't have either, they want you to stay and enjoy yourself so they give you your bill along with a self addressed stamped envelope so you can mail your payment back to them. WHAT? Yo, how can you NOT appreciate this and realize this business wants to please? Loved that so much. We were immediately approached and told of all the amazingness of this spot and it wasn't even our server; they work in teams to make sure everyone is taken care of but you do have a main server. So our welcome was just to inform us of what they offer, the Karma checks, they even let you know that their fries are freshly cut so if they don't taste perfect, let them know and they will get you a perfect serving. Immediately got water and our drink order was taken. You can sample anything you would like. They had one cider so I went with that and it was refreshing and delicious. It was the Colorado Cider Company, Glider Cider. So light. They also offer pairing suggestions for their dishes. For their menus: "At the Mountain Sun Pubs, we prepare all our menu items from scratch everyday. We believe the most important part of being a community pub is bringing you the freshest ingredients we could find and preparing them in a healthy, hearty, down-to-earth style. We choose organic, chemical-free and genetically unaltered products when they are available." I feasted on the Junk BURGER with bacon, cheddar, sautÃ©ed mushrooms and onions with roasted garlic mayo. Cooked a perfect medium and so dang flavorful and juicy. The fresh fries were perfect as well. Such a great, filling lunch. Definitely check out one of their locations if you can! - Mountain Sun - Vine Street - Southern Sun - Long's Peak - Under The Sun

Busy even at 10PM on a weeknight! We stopped in here for a bite after catching some music at the Laughing Goat, and had to put a name on the waiting list. It's definitely a pub atmosphere -- dark, loud, and full of beer-lovers (ie, not really my scene). Neither of us drink, but the staff gave us samples of root beer. I wasn't terribly hungry and stuck with a grilled cheese sandwich with a side of their daily special "Asian" chicken soup. Service was nice enough, though I think three different people waited on us. Edit: The owner reached out to follow up on this review! I'm not sure we'll been in the area again anytime soon to give them another try, but the fact that he took the time to send a message really means a lot.

I sought out this brewery on a return trip to Boulder because it was that good. I also love the team atmosphere and karma envelopes (though I chose to walk to ATM first, the option restores my faith in humanity). Did I mention the beer is phenomenal and the food prices are almost too reasonable? Is this a trick? I guess it prompts one to tip better I had the veggie burger (standard puck, unfortunately) with blue cheese and basil sauce. I put that yummy goodness all over my fries and know for next time to order a side of it for dipping. How do I love thee, Mountain Sun? Let me count the ways: Mountain Sun on Pearl, Southern Sun and Under the Sun on Broadway near Eldorado Springs...that's 3 at least!

We didn't know what to expect since we aren't from Colorado but we were pleasantly surprised! I didn't have any troubles getting a vegan Ruben (which happens to be my most favorite thing in the world). The beer was great, the service was awesome but the sandwich only left one thing to be desired...I'm not the biggest fan of tempeh so I would have liked to had a seitan-based sandwich. Otherwise it was complete awesome sauce! I would definitely go back and would bring all my friends!

Exploring Pearl street and its many treasures earlier in August brought us into Mountain Sun for a drink and a bite to eat. Service was great and the food was tasty. Everyone was friendly and helpful. We got a sandwich and a quesadilla. Hop in for a good meal and a drink and explore the beautiful artwork.

Well, I was in Boulder for only a week and came here three times. My fiance came here four times! That says a lot. We absolutely loved it here. They are very vegetarian and vegan friendly, with everything very clearly marked. The free beer samples are great for someone like me who is picky and has trouble making decisions. Check out dollar taco night, their kind ale, and the delicious black bean burger. We even saw a great band here (The Blackberry Bushes) and bought two CDs. Our service, food, and atmosphere was really perfect on every visit. This is a Boulder must-visit!

It was SO LOUD when we came here on a Sunday at 5pm. I thought that by going to dinner so early we would have a quieter experience, but this it not that kind of place! My partner and I shared the nachos (woah, that's a lot of nachos) and a Date Night burger. I loved how stacked up the nachos were, but most of the chips were soggy and sad by the time we got down to them under the heaps of black beans and salsa. I liked the burger, as I've never had a burger with dates on it before, but wasn't too impressed by the GF toast used as a "bun". Probably would have been better on its own. The fries were really delicious. Free beer (and cider) samples at the bar. They had a cider on tap as well as a GF beer in the bottle. Servers were extremely friendly. The crowd was pretty young, but that's understandable since school is about to be back in session. We saw a good amount of little kids there too so I assume they are at least somewhat child-friendly.

Rebecca R.

My posse and I had a great time here! The friendly staff bring samples on samples of beer! We ordered about 10 samples and liked almost everything we tried! The standout beers: the Hummingbird Honey Ale and the Desert Cities Cream Ale. Despite ten samples the whole table gravitated to these two! The food was also reasonably priced, so we split a huge plate of delicious nachos. I'll be back to hang out here.

Grace B.

I loved the welcoming atmosphere here. Once we put our names on the wait list we were given the option to head to the bar area and sample any beers we wanted before making our selection. That was a great first start and a nice way to wait, along with some fresh cut fries. Everyone working behind the counter made sure we were helped and taken care of. When it was time to eat my husband and I split their bison burger which was superb. Because we had fries with our beer earlier we got a side salad which was a nice way to get our greens in. There's a variety of people that come to this place, families, couples, friends hanging out. A nice atmosphere for all to enjoy.

Darrelle G.

Alex and Anna are the BEST! Wow- what great service. Alex brought us beer tasters during the wait for our table- Anna was a kind and accommodating waitress. My favorite beer is the raspberry wheat! My boyfriend lives the FYI pa. I love boulder and our meals were great. We will be back.

So awesome! Amazingly nice service complimented with delicious, filling food. I got the bison burger (SOOO good) with fries and a cider. Wait was pretty long (30 min on a Friday night for four) but we stood by the bar and they came to get us when our table was ready. This seems like THE spot to go to if you're just visiting Boulder

Down to earth, cool spot! It's loud but that's ok bc food is awesome and beer selection is great! Date night burger - amaze balls! Prices are great too! Cash only!

Mountain Sun continues to be my favorite brew pub in Boulder, maybe anywhere! Tonight - usual great house beers, awesome spicy pollo asada burrito and Tim's blackened chicken quesadilla (regular menu items), great special Tuscan Summer Chicken (marinated grilled chicken with grilled potatoes, artichoke hearts and endive). Tonight's creme de la creme - chocolate cake with a salted bourbon caramel frosting made with their Hooligan oatmeal porter. Are you kidding me?! Awesome. Of course, the usual great wait staff and fast service. All for $60 with tip. Last trip to Boulder and Mountain Sun, my son was thinking about being a Buff. Starting this fall, he will be a Buff. Looking forward to many great beers and meals at Mountain Sun!

Jackie S.

My fellow yelpers didn't let me down on this one. The list for a table is at the bar which is crowded and bustling. Our name was taken and we were handed a drink/beer menu. I got a Colorado Kind Ale, delish. We were seated in 10 min and given the rundown on how the service works. (There's a team). I got a small salad to start fresh, diverse and good balsamic vinaigrette. My son had a burger which was good and I had the chicken burrito which I was warned was huge. It was really good and service was impeccably attentive. The only slight critique Id have was it felt a little rushed. Other than that it's a cool vibe w wholesome fresh fare.
(5)
Amber A.

Two words; chill and beer. This place is super laid back and has great beer. Colorado Kind Ale is the beer we chose and it is good- a lot like flat tire. Also had chips and salsa which was good. We got a couple seats at the outdoor area which was fun people watching!

Robin S.

We stopped in here because I'd read good reviews of it last time we were in town and we were SUPER hungry. Its a pub menu so I didn't expect a ton, but they actually had some nice vegeterian dishes and salads. I got the special; an asian salad with tofu and my husband got the cheesesteak. The salad. WOW. Super fresh spinach, arugula, basil, edamame, carrot and fresh red pepper. I mean, who knew you could go to a pub and get an amazing veggie salad? the tofu was perfectly marinated and all the veggies were fantastic and crunchy...the carrots were even fresh shaved. The dressing was off the hook good. Hubby loved his cheesesteak. We also got a side of fries that were clearly house cut and cooked, and were delicious. Hubby loved their Kirsch ale. I got the pink lady which was pretty weakly made (first night at elevation and I should *feel* my drink and didn't at all) but hard to complain for the price as it was our cheapest meal in Boulder. Worth a visit for sure! We'll be back.

Great place! Excellent selection of beer. Excellent selection of food. The wait staff was helpful and friendly. The decor is fun. The Java Porter was awesome! The nachos were more than enough for a meal or two. A little loud, but not too bad. Easy parking on a weekday. I really liked the tempeh rueben. Good selection for vegans and vegetarians. Service for us was fast and attentive.

Great beer, tasted like one of my homebrew recipes. Food was awesome, great meat on my burger, everything tasted fresh. The pesto grilled cheese... Just get it. Dont argue, just do it. I usually like syeak fries but these shoestring fries had great flavor. Reallly great flavor. Mmmmmmm fries. Happy servers too, all really helpful. Go here, eat, drink beer, be happy. Cheers!

This place has great vegetarian items (both light and crazy heavy like the nachos). Their beers are amazing, and I believe they are owned by the same people that own Vine Street in Denver. My only gripe is that they dont accept cash.

I was hanging out in Boulder today with five other adults and my little one. It was time to eat and we were looking for something to please us all; a couple vegetarians, meatarians, beer lovers and a child. This place seemed to fit the bill. We were lucky enough to get a table immediately, by the end of our meal the place was packed and on a wait. I just mived t o Colorado and have been eating EVERYWHERE, so I felt like I should take it easy with the half sandwich/soup combo. I got the Boom Boom (a veggie sandwich) and took the servers recommendation, the veggie chilli. Sandwich was delicious, soup was awesome, and it was was plenty of food. I was struggling in deciding on which beer to get, they have a fantastic lineup. She let me try two samples, a tripel and a barleywine. They were both QUALITY! Then I remembered it was noon on a Tuesday and I completely 360'd and went with a kolsh, great decision :-) My comrades choose burgers, a steak sandwich, a veggie burger, and I got my kid some fresh veggies. The dudes all gooed over how amazing the burgers were, I believe that I heard "best ever." Super great service, beautiful decor, and fabulous food. I see myself coming here often!!!!

I went to Southern Sun first and was surprised how small this place was. Despite that, we had a party of about 10 people and they were nice enough to keep us updated on getting a table and were willing to push three tables together for us even on a Friday afternoon. Good beer, good pub food, and a fun place to hang out! The raspberry wheat beer was my favorite but they just changed it to apricot wheat.

Lucy H.

Solid food - I've never had a bad meal here. The staff seems very friendly and helpful when picking out your entree or drink. Cash only but there is only $1.00 surcharge for their in house machine. I want to go at night but during the day it's family friendly and quick service.

South A.

Very good food! All staff were friendly and attentive. Love the karma policy - no cash? Take the bill with you and Mail your payment when you get home! Had cheeseburger. The beef was very good, tomatoes were very fresh. Crowded at lunch but we got there at 11:40 am on Wednesday and easily got a seat.
(5)
Tim C.

Good food, good beer, mediocre service. The wait for a table for one was half an hour at 9 PM on a Sunday night, even though there were empty tables when I walked in with no one making a move to sit there. It's cash-only. The ginger wheat beer is good. The server messed up my order, which is understandable on its own, but then when another server brought my fries (without cheese) and I said I ordered cheese fries, that person never brought back my cheese fries. My original server came back to ask me if everything was OK after 20 minutes or so and seemed surprised when i said I hadn't gotten my cheese fries. Also, a third person asked if I wanted change when I paid my bill; I said yes, but he never came back with the change, so eventually I got fed up and left. The menu explains that the business is run cooperatively with everyone taking turns doing different jobs, and waitstaff teaming up to help each other's tables during one evening, but based on my experience this just seems to lead to bad, uncoordinated service.

Amber L.

The majority of these reviews were spot on! The junk burger was awesome! My brother got the special wrap, amazing!!! And my boyfriend got the go gooney bird, my option, a little dry.. But the beer was fantastic and service incredible! I would most definitely come back. And bonus if you buy a tshirt on a Tuesday, they'll buy your beer :-)

After a performance at Macky Auditorium, found them via Yelp app as highly rated. Craved a burger but was informed the kitchen was closed on arrival. Server kindly offered nearby burger options when asked but I decided to stay since I was already here and they do have dollar tacos (in chicken or veggie.) Ordered 2 veggie tacos and an 8 oz Big Krane Kolsch. Requested an 8 oz Blackberry Wheat brought out when the kolsch was low. Kolsch was good. In fact, made me wonder what "legal" KÃ¶lsch is like. Tacos arrived a little later. They are soft tacos on flour tortillas and are reminiscent of fish tacos sans fish (with cabbage, I think.) They ended up being chicken, but I didn't care since I'm not vegetarian. While it was the wrong type, they redeemed themselves by being far better than the price would suggest. Blackberry Wheat was served right on cue. It's more... colorful (?) than imagined and sweeter than I'd like. Maybe even a tad medicinal initially, but that impression faded after a few sips thankfully. Not terrible, just not my preference which is to get more of an essence than actual fruitiness. (The Watermelon Kolsch from Golden City Brewery achieved this for me.) In all, I was happy with the service, food, and beer. They've earned a return visit and I look forward to trying a burger... P.S. It probably bears repeating that they are CASH ONLY (or local check - ha.) There's an ATM in back.

Cristen T.

My husband and I stopped in at Mountain Sun Pub for an early lunch. We had a nice and helpful server. He had some great suggestions about beers and was happy to get tasters for Mike to sample. After he decided on a beer he really liked, we ordered some food. We weren't super hungry so we got a Quesadilla and the Speakeasy Steak Sammich to split. The Quesadilla was awesome in a way that I didn't know quesadillas could be. It was packed with veggies and not gut-busting in any way. The salsa and guacamole that accompanied it were fresh and flavorful as well. Mike said it the best when he voiced his thoughts aloud later: "I had no idea, when I ordered that quesadilla, I would be as impressed as I am." It was a great price too! The meat in the steak sammich was expertly cooked but maybe just a touch under-salted. I loved the use of arugula and caramelized onions in this sammich. The arugula was bright and peppery and the caramelized onions were just the right amount of sweet. I enjoyed the artwork in this place a lot. There is a great floor-to-ceiling piece of art near the front window that is colorful and creative and their ventilation (near the ceiling) have hops painted on them. Just a quick word about dogs... While we were heading inside, a few people and their dog were asking if they could sit on the patio. One of the staff let them know unfortunately dogs are not allowed on their patio. They are also cash only so come prepared!

Allison G.

YUM - I got food to-go twice from here. The people are very friendly and will quickly asked if you're being helped when they see you. I have had the hummus and cheese sandwich. It was really delicious with the right amount of hummus. The bread was fresh and the vegetables too. It came with a pickle and tortilla chips. Also, I have had the customizable grilled cheese sandwich. I made mine with cheese, bacon, and tomato. This is a must try if you love grilled cheese. This also came with a pickle and tortilla chips. Both came in to-boxes that were easy to recycle. I love that. The food is delicious which is why it encouraged me to sit down at Southern Sun.

Great beers, and their grilled cheese and soup mix is phenomenal. Bring cash though, they don't accept credit card

Dana B.

With a funky atmosphere, you'll feel welcomed as soon as you walk in the door. Don't be turned off if the place is packed and there's a wait, free beer tasting at the bar during your wait time! The free beer samples and crazy wall art kept us occupied during our wait. When we got seated, the menu looked too delicious to let us decide. Our awesome waiter was patient and pointed us in the direction of his favorites, they did not let us down. The nachos were to die for, cheese on every chip! We had the date night burger, quesadillas, the junk burger, and the speak easy steak sandwich. We loved everything about our meal and we will be back for more. To make our meal even sweeter, the prices at this place are phenomenal! Make sure you have cash! Mountain Sun only accepts cash or check, they do have an ATM in the back.

My goal is to visit as many Colorado breweries that I can before our family heads back to Florida. Mountain Sun Pub & Brewery was my 14th brewery since August 21st. Bryan M and I had two of our teens with us. We were headed up to Nederland to enjoy the fall colors. We were looking to grab a bite to eat in Boulder where I could also enjoy some local craft beer. Bryan & I had been to Vine Street Pub & Brewery during our 2012 visit. Mountain Sun & Vine Street is part of the same family. We enjoyed our visit back then, so I knew stopping in Boulder would be good. Mountain Sun has more of a "Boulder" restaurant feel that serves in house beer than a brewpub (similar to Yak & Yeti). We got a booth and while they browsed the food menu I took a look at the beers. I got a flight consisting of: Raspberry Wheat, Illusion Dweller IPA, Annapurna Amber, Rouge de Bruges, Hummingbird and Isadore Java Porter. All the beers were solid. I enjoyed them all with the Porter, Hummingbird and Rogue being my favorites with a 4.5* on Untapped. The Porter has a great coffee smell and taste and the Hummingbird smells wonderful with its orange blossom honey. It's always nice to enjoy great beers with some tasty food. Everyone enjoyed their lunch and the kids got a kick out of their "Karma" policy. They only take cash or check. If you don't have either just mail the payment when you get home. I can see why Mountain Sun is a favorite among the locals and tourists alike; the beer, food and atmosphere are one that is wonderful.

Lexi S.

The service was outstanding! The hostess invited the group I was with to the bar for free beer tastings while we waited for the table. The bartender then offered many suggestions, and almost a dozen beers were probably tasted. After being seated we were welcomed by a very enjoyable waitress who was personable with us the entire time. We joked around with her at the same time she gave us some tasty suggestions. The date burger (substituted chicken for beef) was a pairing I never expected, but will have to recreate at home. And no words could be said about the chicken burrito with red and green chili! I will come back here when I revisit Boulder in the future.

Love this place!! They have great beer, great burgers, and a great atmosphere. The date night burger is my fave! AMAZING!! Be sure to bring cash because they don't take cards!

Leanna C.

I am a huge fan of all of the mountain sun establishments! The beer selection is always amazing. I've never ordered a meal here that I didn't like. If you like fruity beers definitely try the blackberry wheat beer, I typically get a growler of it to go because I can't get enough of it. Food, oh boy where to start? I love the salads here, but you can't come here and just order a salad. I usually get a burger and get a side salad with their homemade balsamic dressing (it's actually life changing). I almost always order whatever the special is for the day, usually some sort of burger or burrito that is just a little different from all of the others. Without a doubt try the date night burger and the burrito smothered in green chilli. Everything here is always great BUT you have to have a local check or cash at all of their establishments (southern sun, under the sun, and vine street pub).

Daniel B.

Been hitting up the Mountain Sun for almost 20 years I've lived in Boulder. Even stopped here on my first date with my (now) wife. And I don't even drink beer. I think the Mountain Sun has one of the most underrated burgers in Boulder, the Junk Burger. Love it. Order it every time I come in. Service is often good. No complaints there. For beer lovers, I'm sure they have something for everyone, but if you're an omnivore like me, then give the junk burger a try too.

Rw F.

One of the few places on pearl street with a wait on a Monday night, packed with patrons inside and out. Even having to wait for a table wasn't bad. Free beer tastings at the bar until we were seated. The pesto grilled cheese was good. The fries were good too. The black bean chili didn't have enough spices though. A very friendly place to hang out. Plenty of kids games to play and a very good waitstaff encourages you to linger.

After several recommendations while sampling brews at other breweries around Boulder, we stopped by for a beer flight and some burgers and we weren't disappointed! We had the bison burger and junk burger, and both were delicious! Great atmosphere and great location on the Pearl Street Mall!

Great service, amazing food and beers! Bison burger, quesadilla and burrito were all delicious! This place has both great food and great beers. Not the typically bar food. It's an actual restaurant first. Won't disappoint!

Excellent place! Beer samples until you find the "right" one. The most perfect burger: SOB Burger. And good prices. It was a bit loud but clearly a happening place. Would certainly come back!

Rachel D.

Really nice place. We waited up at the bar for a table, they let us try a lot of different beers to make our decision, and we even got free fries while waiting there (and the wait was only 10-15 minutes, not bad). Once we got a table, we were able to choose from a variety of boardgames to play (we chose Battleship, I totally won). The servers all work together as a team, and were very helpful. The food was delicious, so was the beer!

Nivedita B.

Stopped by for lunch after a nice hike at Chatauqua, and pretty much cancelled out my exercise with burgers and beer. Totally worth it. The restaurant was full but the awesome friendly guys at the bar made us try a bunch of beers while we waited and gave us crispy fries, all fo' free. They seriously filled up the small glasses as free samples. I was pleasantly buzzed by those alone, lol. My favorites were the nitro Pearl Street porter and raspberry wheat. For grub I had the date night burger. I wasn't expecting to be blown away by the burger, but honestly it was one of the most scrumptious burgers I've ever had. And I'm pretty sure it wasn't the beer talking! :) The salty bacon and goat cheese combined with the sweet date puree was a marriage made in heaven. I can't remember what my boyfriend had because I was too enamored and obsessed with my burger. Our server was super friendly and attentive, too. Overall, what a fun place! Don't forget it's cash only! Great beers and service. If you like goat cheese, don't miss the Date Night burger - heavenly.

Taylor W.

Just stopped in to try a beer of theirs and didn't realize they were cash/check only. FYIPA is delish. The wonderful bartender was so kind as to take care of my beer since I was just stopping to try them out. Amazing hospitality and customer service. Will definitely be back here!

Kelli H.

Mountain Sun is one of my go-tos when I have friends in town and want to show them great beer and great food. What really puts Mountain Sun over the top, though, is their impeccable and friendly service. The last two times I've gone, I've gotten several of their seasonal beers - some on nitro which always adds an extra touch. My favorites so far have been some of their sours. To eat, I've gotten the date burger, with goat cheese, date spread, jalepenos, and bacon. It's just the right amount of sweet versus savory to make this burger awesome. The second go around, I got the falafel sandwich with fries and the goat cheese and watermelon salad. The part I like the most is that, although this is a cash-only establishment, if you ever forget your cash, you can mail yourself the bill and send them payment back. What a trusting company!

This place would get 5 stars. Great grub, awesome beer choices, gluten free options, excellent fries. BUT, it's cash only which gets me every time.

Great beer!!! I had the xxx IPA and it was fantastic. The food I had wasn't great though. I had the chicken sandwich and I would recommend sticking with a burger (the burgers looked really good). The service was unconventional but it worked thanks to the servers really working as a team. The atmosphere was great too. The prices were excellent, but be warned they only take cash (they have an ATM if you need it) All in all this place would be a 5 if the food I had was better. I believe the food was an anomaly but it's my only experience here.

Burgers & beer! It's a winning combination & this pub does it right! We went straight off our flight and it was one of the few places open late. It was bustling with college kids & locals and had a great laid back vibe. They have an array of beers to choose from, and they were gracious enough to bring me a few samples. The beers are very reasonable in price with most of them being $5-$7. For my burger, I decided to go with the special- check the board when you walk in. It was a stout bistro burger with caramelized onions & pears cooked in stout beer, with a Gorgonzola cheese. Despite the strong flavor profiles, the combination was harmonious! You have the sweet onions & pears which balance the Gorgonzola, and the stout flavor was perfectly subtle. Service was great. Everyone pretty much takes care of you and you have several of the servers coming around at all times. As to the only downfall- cash only! But definitely a great option in the Boulder area for some great food at a very reasonable price!

Black and blue burger is the best. Food and staff are nothing but excellent time and time again.

You know, I have to say, when I was younger I disliked this place (simply due to the hippy crunchy vibe) but I am glad I gave this place a second chance. I go in and I have a great meal, not expensive and the service is always on point. I would like to formally apologize for being a judgmental jerk in my youth and I am glad I was talked into rejoining your hippy crunchy cult of great food and service. I don't drink and the place is quite comfortable for someone that doesnt indulge in the adult libations. The root beer is quite good and I always feel comfortable.

Servers were friendly and helpful. I'd definitely recommend the chicken nachos, however, if there's only two of you, ask for a half. No one told us it was a large portion, so we had plenty of leftovers. We split the SOB burger and we were not blown away, it was mediocre.

This is the first place we stopped at once we got in to Boulder. It was a Saturday night and there was not a long wait, about 15 minutes. We were able to grab some beers from the bar while we waited. They had a great selection of beers and they offered samples. Which I loved. It was nice to try their beers before you purchase one. The beers were all pretty affordable. Once we sat, the waitress came around with our menus. The food sounded pretty good. I order the special, Alaskan crab Mac and cheese. Sound amazing. My girlfriend order the main burger. I forgot name. The good came out and the Mac was not that good. It looked good but tastes too fishy. I was a bit disappointed almost to the fact I wanted to ask for something else. Soooooo disappointing. The burger was pretty good. I would probably give it 4 stars. Nice bread, slightly crispy, good tasting meat, and tasty fries. But the Mac was just not that good I can't give this place more than 3 stars Don't get me wrong, I would probably go back for the great beers and affordable price but I would stay away from Mac. :-)

We've been coming here for years, and have always enjoyed it. This visit really stood out... AWESOME beer & total team effort. They were the busiest business on Pearl Street on Friday evening. Yet the GM, Jess, had her team super well organized. They flowed in unison, with probably has 6-7 servers recommending beers and repeatedly bringing us samples. We felt really part of the family. Thanks!

Just have to say wow! I rarely if ever write reviews, but their service last night was so top notch that I couldn't help myself. We just moved to the area from TX, and were looking for a good beer and pub location. A friend was in town so we figured we'd give this a shot. From beginning to end, we were shocked at just how awesome this place was. When we arrived, it was pretty packed. I saw a sign about putting your name on the waitlist at the bar in the back. As I was about to head that way, a waitress offered to walk us back there. Then she asked if we had been there before (we hadn't) so she poured us all a free pint while we waited. Oh, and the kitchen made some extra fries by accident, so she gave us those as well. I had the black and blue burger along with a few IPAs. The bill was very reasonable, and I was shocked at how nonchalant they were about their payment methods. So they only accept cash, but gave us a few options. We could use their ATM in the back to grab some cash, or they'd give us an envelope and we could mail them a check when we had a chance. Or heck, he said, just pay next time you come see us. Btw, the food and beer were both very good. We'll definitely be making this a regular visit for us.

Came in from Chicago and had a phenomenal visit! We went on a Friday around 7:00 pm and waited for only 25 minutes. While we waited we had a few of their brews and were offered free pub fries while we waited. We ordered a date night burger and a streak sandwich and were not disappointed! All the food was so good and the workers were all so friendly and fast. Some tips: They have free tastings for all brews! Games are available for while you wait! Free fries!

The burgers were good, but nothing that really blew me away. All in all, I'm not opposed to eating here again, but it doesn't stand out in my mind as my first choice.

Leslie G.

The service here was freaking weird. Our server either didn't hear (it wasn't loud in the restaurant!) or didn't understand what we were saying. I had to say my order like three times before she realized what was going on. It was like she just woke up or something and was out of it. Actually, now that I think about it, maybe she was sleep walking? I'll blame Ambien for this one. The beers are solid. I especially liked the Rye IPA. The food was kind of meh. I remembered it being better. It's cool they have lots of vegetarian options though.

J. E.

It's been awhile since I was here, but I really like it. Good beer, good food, good service. Parking can be challenging though, so we usually opt for Southern Sun over this location. However, there are a couple of a parking garages not far, so sometimes we have used those when street parking was too difficult to find. On good weather days, we park further and walk or bike over. Bring cash as they don't take credit cards.

Totally love the happy hippie vibe of this place, but was really blown away by the service last night. Staff was apologetic that things were running a little slow - we didn't know anything about it because as soon as we were seated, they brought out free fries just because they were feeling like they were running a bit behind. I ordered a veggie burrito and wanted it vegan - no cheese or sour cream. I asked for the option to add veggie green chili. Because things aren't labeled super clearly, it wasn't apparent to me (or my server) that the green chili actually isn't vegan because it's made with butter. Before the order came out, another server came by a few minutes later and apologized thoroughly and sincerely that the chili isn't vegan, and that they were going to make me a new burrito and that it would be on the house! Most places would either not tell you that what you ordered wasn't vegan and serve it to you anyway, or realize their mistake and wipe it off or cover it up somehow. I totally commend the honesty and customer service ethic here. The only thing that would improve it would be (1) make your veggie chili vegan! Earth Balance, made right here in Boulder, is just as tasty as butter. Also, is butter really necessary in chili? OR (2) clearly label what's vegan to avoid confusion. Your honesty and integrity earned you a loyal fan, though, and I'll bring all my friends who come through Boulder to Mountain Sun from now til forever. XXOO.

Solid burger joint if you find yourself in Boulder. Food: nice selection of great tasting burgers (including veggie), plus some sandwich and salad options. Served medium - the way a burger should be served! I had the Bison Burger, which was great except for the fact that I have more bun than burger. Ambience: loud crowd of all ages, definitely with some skew to the younger side. Also a little crunchy / hippie feeling, which I dig. Not everyone's cup of tea though. Beer: great selection of Colorado brews, and they even providing free tastings.

Great beer, friendly servers, awesome atmosphere--the food is yummy and great attention is paid to satisfaction at this establishment that honestly cares about providing customers quality at a reasonable price. You can tell that everyone from the host/hostess all the way to ownership take hospitality seriously. Good to note: this is a cash-only spot. They do have an ATM towards the back if you forgot!
(5)
Matt D.

By far the chillest place I've ever been to (besides the monk temple in Chiang Dao). This was also our first place on our travels in Colorado. Let me just say... 1. They rotate the artwork - keeping things fresh! 2. They brew their own beer - Craft beer at it's finest! 3. The food is super satisfying and priced appropriately 4. It's Cash or Check only... yes I said Check lol, but there is a little secret if you don't have a Cash, Check, or Debit Card to use at the ATM... You'll have to just go to find out the little sweet-awesome secret Next time I'm in Boulder, you betcha I'll be back.

Passing through Boulder, CO we wanted to check out Pearl Street Mall and stopped for lunch here. Even though it was super busy, the service was wonderful and the food excellent. I had their Peachy Keen Burger which was made with local Colorado beef cooked perfectly, topped with their peach salsa, organic arugula and cheese. We received their hand-cut fries free while we were waiting. Even better, they comp'ed us a free meal because of a kitchen mix-up where the wife's meal was a few minutes late! If I lived here, this be a regular place to visit. They also served great local beers.

The Good: Mountain Sun is a must-try, old-school Boulder staple. Mountain Sun on Pearl Street is the original casual restaurant & brewery -- if you're in Boulder, grab a Junk Burger and craft beer here! They've been in the same spot on Pearl since '93 (!) and have three other locations -- Southern Sun & Under the Sun in South Boulder off Broadway & Table Mesa, and recently opened Longs Peak Pub in Longmont too! The vibe is casual and the place is always packed. Be sure to check out the coolest specials board in town featuring gorgeous, detailed, incredible chalk art by local artist Bryce Widom. The board changes with the seasons like their rotating beers and takes up to 14 hours to produce -- when you see it, you'll know why. The atmosphere is very Boulder, I recommend this spot for out-of-towners to get a feel for old-school Boulder before it got all fancy. Great people watching, lots of locals, no TVs, open layout with taps in the back. They have live music most nights and it gets even busier then, so be sure to get there early and hold it down! The Bad: The place is a well-known Boulder institution and as such, it can be hard to get a seat, especially on live music nights (if you can't get in, go down to the Laughing Goat coffee shop, they have lots of live music too!) I also wish they'd blanch their homemade fries! The Food: Tasty old-school burgers with additional offerings for kids, vegetarians and gluten-free folks. The menu has been the same as long as I can remember - if it ain't broke, don't fix it! They source local and organic food whenever possible, in true Boulder fashion. The Service: Service can be kind of slow -- maybe our mistake was taking up our server's kind offer of free tastes -- we ended sitting at the brewery for twenty minutes without a beer waiting for our seven mini tasters, so it might be a good idea to taste the beers old-school - order a pint right away and get it without delay! Overall: A must-see stop for visitors and anyone who claims to be a Boulderite. Get a burger and a beer and hang out here if you're in Pearl, this place is legit.

This place a so cute! Staff were super friendly and helpful even while we waited 45min to be seated. The custom grilled cheese was delish, I added avacado and bacon to it. Highly recommend just for service alone! Hard to find places in Colorado that truly care about customer service! Check em out!

C T.

I've dined at Mountain Sun more than once, and am always more than happy with the food. Great options on the menu, and they cater to those that don't eat meat or dairy. Also, great beer! The only reason I didn't give it one more star is that they're typically very busy and you will likely not have a very quick dining experience. That being said, this is likely due to their popularity and great food!

This is a fun place to experience Boulder culture. Upon entering, it seems a little chaotic. You have to go to the bar to put your name on the list for a table. But you you can order drinks at the same time. The service is super fast and friendly. I was in town for four nights and came here twice and will stop by next time and I'm town.

First of all, I'm not a big beer fan, so my review will not focus on beer. I went there with some intern friends, we were in a big group so needed like 3 tables, the staff there were very friendly, from waitress to cashier, they only take cash but luckily there's a atm in the place! The place is pretty with a lot of paintings on the wall.

Wow- all I can say is wow- first the service was superb- the waitstaff was incredible and took care of any need we had. My wife's meal came a bit after the rest (2 min) and the manager comped the meal despite me saying it was OK- The food was great! My kids and I had burgers, and my wife had fish and chips. Her meal was outstanding while the burgers were great- They have a full bar and serve generous drinks! The only caution I would give is they are cash only- but here is the really incredible thing. They have the "karma" envelope- a self addressed stamped envelope to send them a check for your bill if you do not have cash or an easy way to get cash at an ATM - the manager nearly insisted I use the option as I tried to use a card- I was struck by their willingness to delight a customer! Would I go back? Absolutely and I recommend others do the same!

Seriously, after this meal I wish I lived in Boulder! I may never be able to have another burger again because nothing will measure up...my jalapeÃ±o burger was cooked to perfection and I highly recommend the garlic mayo to accompany the fries.

Okay....who in the heck made such a great going place as this!! I was in town for six days and was recommended to check this place out by a local local. After the first try....I had to try hard to not come back for every other meal (and the awesome vibe/staff/attitude). Now there is a ton of great foodie places along this way but I was very impressed by the simple way the staff worked and the standard they have. Not sure how to better describe it- I love the idea of having a restaurant, serving great food! in a manner that you get excited about. Alright Mountain Sun, I am taking notes :) F-ing Awesome!!

First place I dined on my visit in, and last place I went to on my way out! The cheap prices make this the most affordable, good meal around Boulder around Pearl St area I think you'll find. Very good large portions. Their nachos looks massive! I really loved the fantastic Steampunk-ish chalk mural on the inside wall too.

This place gets five stars for the beer I haven't been able to stop thinking about since my visit: Bourbon Addict Imperial Coffee Stout. That beer was perfection and consumed my thoughts and cravings during my four-day trip to Boulder last month. I want more. I need more. It keeps calling me, man. *Pookie voice This beer was bursting with bourbon notes, oak, dark malt, toffee, vanilla, caramel and of course, coffee, but it all worked so damn well together. Despite the high alcohol content, it was smooth, creamy and full-bodied. It really was a work of art. I also must commend the brewers here for the Belgian Black IPA, as that too was superb. These two beers stole the show. As for the food, I only snacked on a few nachos, but found them to be packed with plenty of flavor. But you don't need food when you have Bourbon Addiction. I have the Bourbon Addiction. I need my fix.

Riesa L.

Great lunch spot. I had the make your own grilled cheese with tomato, red onion, and bacon. So good. The Moscow Mule had lime zest, which I'll be adding to the mine the next time I make them at home. The ginger beer could have had more of a ginger kick, but overall it was a decent drink.

Not a big place and they kind of pack you in, but their beers make up for it. Friendly service and clean. We had 7 people and they accomodated us in a timely manner. I had a Margarita which was fantastic and the rest of our table had beers which are quite tasty. I also tried the Junk Burger, really good beef, they try to get you to order it Medium but I like mine Medium Rare, my burger still came out Medium :( I also asked for very crispy fries, our server forgot, and then brought out a basket of crispier fries but still not that crispy. Not sure our server really listened to our requests but would def go back to try some other entrees.

I judge a brewpub by the beer and fries. I had the Number One and Southern Skies which were the best beers I've had in Colorado. But the fries are to die for. Truly fresh cut. Delicious. Boys loved their bison burgers and chicken sandwich. Cool place.
(5)
Kim M.

One of my favorite places to go to in Boulder. Great beers and food. There's usually a wait because they're so popular. But, the advantage of it being a brewery is you can head to the back and grab a beer while you're waiting. They let you sample any beer you want for free. I've tried most of their burgers and I have no complaints about any of them. 2 of my favorites are the date night burger and junk burger. But my go to order is their spicy pollo asada burrito. It is delicious and a good sized portion - I always have leftovers! FYI it's cash only, but they have an atm in the back near the bathrooms that has a service charge of only $1.

This place is extremely popular. It seems to draw it's crowd from the chill atmosphere. The laid back vibe attracts lots of people so be prepared for a wait. If you do have to wait you can get a beer from the bar and order some fries. You may not even have to do that though. When I said this place is chill, part of that came from their habit of giving away free stuff. We had just ordered a few beers and thought about getting fries but the staff just asked us if we wanted some and gave us a basket. That's not the first instant of giveaways experienced by us at this pub. We came in for a late lunch when it wasn't so crowded and they asked us if we wanted to try some new brews. Thinking it would be sample sizes we said yes and we were surprised when they brought over full beers. Pretty sweet. Be aware that not everything is free though. They charge for ranch. This annoys me because I'm a fat kid at heart and enjoy ranch like how most people enjoy ketchup. But after joking around about how little ranch we got for the fifty cent charge, we learned they make all their sauces there, to include the ranch. Considering it was tasty ranch, I developed a respect for the fifty cent charge. Despite the chill vibe and great service, this place only gets four stars. The food is just ok. Yeah the ranch topped it all off nicely but it was overall lacking. Nothing all that special. But if your looking for a place to just hang out with friends and a few beers, definitely check this place out for a hangout.

Lacey M.

Small but cool place. They definitely do not skimp on the toppings here! We watched a few plates of nachos go out while we were waiting for our table and they looked amazing...covered in salsa and black beans. We ordered the cheese fries and there was seriously so much cheese throughout the whole plate, not just on top. They also offer free tastings of their beer at the bar. I ordered the basil blue cheese burger and it was perfect!

Clearly, restaurant selection after camping 3 nights or longer is critical. It's almost a spiritual occasion after eating nothing but cliff bars and "just add water" foods, all while burning thousands of calories. Of course anything would TASTE delicious, but after dreaming about this moment for hours on end: few places fully SATISFY. Mountain Sun is one of those places.
(5)
Jia Lu N.

I've been to Mountain Sun twice since arriving in Boulder (which was 2 weeks ago...). Both times, there was a short wait--not longer than 15 min each time--and they offer free beer samples in the meantime! I had the raspberry wheat which was sweet but not too sweet, and I would get it again. To eat, I had the bison burger with fries and the spicy pollo asado burger on the second visit. Both were outstanding! Flavors were unique and worked well together, burger was juicy, burrito was the kind you eat with a fork and knife. This may become a weekly tradition...
(5)
Monica V.

This place is fantastic. I came at a busy time but it was worth a wait. Had the SOB burger and LOVED it. Easiest top burgers I've had and I've traveled a bit. Fries are delish and the service is great. Beer is good. I will definitely come back.

Tried to like this place over the years, but it never was to my liking.. Tried it recently again, after a few years, only to be very disappointed. Same menu after..15 years? Too much something in the beer, after two i am hung -over the next day! No credit cards. I get it, they are evil, but hey why not reflect the savings on to your customers..Just saying'. The service is mediocre at best, the system of pooling tips and numerous servers does not really work... Last the attitude of the severs seems to be a bit lazy and pretentious, does not sit well with the oil soaked fries.

The atmosphere is cool and casual, very Boulder. Great beers, great fries, CASH ONLY. There's always a wait, but it's worth it. They brew their own beers, and they're great, so just go to the back and order a beer. BEST fries in town - they also have burgers, appetizers, fish and chips, soups, vegetarian choices, etc. Specials menu changes frequently. Staff always seem happy, pretty hip. I've heard Mountain Sun has great management - either way - t's a good feeling place. For the love of god, BRING CASH. Update - we went to the South Boulder location. Not realizing there was a cool upstairs just like the Pearl location, we sat in the more formal and quiet downstairs. Food was great as always.

Saw the reviews on Yelp for this place, and people raved about some of the best burgers in Boulder. They were right! Amazing food, and the hand cut fries were some of the best I've ever had. Nothing at all compared to the service, though. The wait staff was friendly, laid back, joking and easy to get along with. Quick to check on tables, and attentive. Great Boulder lunch experience, thanks!

Rarely do I give anyone a bad review. I still don't want to. For the most part the service was good, the atmosphere relaxed and fun, and the beers were great. I ordered some pork belly tacos that the server said were a favorite. Maybe I don't know what pork bellys are, but what I bit into looked like a giant frenchfry but was pure gristle/fat. I was taken aback. I threw it off my plate thinking maybe I just had a bad piece. I almost threw up. I had one or two more bites that were really good. Tasted bacon/hamy/meaty. But after three more "gristle fries" I picked all the "meat" off my taco. For $13, three tiny tortillas with some crunchy cabbage and a little dressing didn't cut it. Everyone else seemed to enjoy their meals. I'm willing to give it another chance but would caution against those pork belly tacos. It wouldn't be difficult to use some really good shredded pork.

We were once huge Mountain Sun fans, back in the day. I still have a soft spot in my heart for the friendly hippies, the overwhelming nacho plates, and the casual attitude. But we are now older, and I find that the noise level is difficult, so we don't go as often. And there are many new brewpubs in Boulder to compete. It is a great place to take kids, because they can't possibly disturb anyone, and its a fine place to sit down after work, hoist a pint, and have some of those aforementioned giant nachos. There is also a chalk mural by a local artist that is updated regularly, and it is always charming.

Jade Q.

I checked out Mountain Sun again, and this time I actually really loved everything I got. My friend insists that I had just been ordering the wrong things. This time around, I ordered the Glider cider, which was very good. My friend and I ordered a basket of fries as an appetizer and requested ranch and jalapeno aioli as dip. The fries were delicious, as were the dips. The aioli was super good, and the ranch is actually truly awesome. They make it with dill, which really takes it up a notch. I ordered the Junk Burger except with a vegetarian patty and no bacon. It was super delicious. I also ordered it with a side of the soup of the day, which happened to be tomato bisque. All of it was amazing. I thoroughly enjoyed my meal and had a few leftovers which I just ate now. I suppose my last review was due to ordering the wrong food in the past. I still would not recommend the black bean chili nor the Reuben. Burgers are what they really excel in, and I don't even like burgers, but they do it right. Lastly, I was very excited to see that they took that Cupcake wine off the menu. *phew* Service was great, and I can now say I see myself coming back in the future.

If this were in my town, I'd be here all the time. Excellent service, great beer on tap, delicious food, fun vibe. Wish I didn't have to be on vacation to come back for another pint and nosh.

This place is freaking awesome. Great tasting beer and amazing service. Free tastes of all beers and lots of them. Food is excellent. Fries are awesome. Burrito very awesome. Beer selection is excellent, especially for a craft beer aficionado.

ETA: I bumped my original rating up from two stars to three, because the next time I went, the owner and staff went very much out of their way to make sure my friends and I had a nice time. I will also admit that the french fries and beer are hard to beat. I'll probably get kicked out of Boulder for a two-star rating here, but I haven't had great experiences at Mountain Sun. I want to like this place more than I do. The service is consistently slow, and I just haven't had good meals. I know many people love it, and it has been a local favorite for many years. I'm not impressed. One time when I ordered the vegetarian chili, I thought the meal was reasonably good. I hate to say that it's the only time I ended up really enjoying what I was served. If you go, do it for the beer and party atmosphere. Also, the fries are pretty good. Be prepared for a long wait getting seated, a longer wait getting your food and for mediocre meals. The good things about this pub and brewery are that the ingredients are fresh, and the people who work there are usually very nice. I do appreciate that. If I could add an extra half star to my review, I would, just for those two reasons. Go with friends, not to have a great meal but to have a fun experience.

This place rocks! Great food and great brewpub. There was a bit of a wait and one of the Manager brought us some free fries while we waited. The staff was wonderful from the bar guy serving beers and letting is sample to our servers being helpful with refills and other stuff. Great place!

During my visit to Colorado a friend suggested that we have dinner here. It was about 8 or 9 pm and the place was crowded! While we waited for our table the bar lets you sample any beer you want, so we tried quite a few. The selection was great and all local, which is something I really like. The atmosphere was great, although fairly loud. The food was good as well, I definitely recommend the vegetarian chili! This place was interesting, however, as they only accept cash. They do have an ATM near the bathroom, but I heard that they will also send a bill to your house. I thought that was quite unique. They lost our ticket when we went to pay, so they took care of all our drinks, which was unexpected, but nice! I was speaking with the owner of the restaurant while waiting to pay and after finding out that I was from Oregon he said that the restaurant was modeled after McMenamins, which is one of my favorite places from home. Great experience!

Really amazing ambience and staff. The "team" of servers who take care of you are friendly and funny and very efficient. The beer is great and very reasonably priced. I had the avocado and cheese sandwich with fries and my boyfriend had vegetarian black bean chili and tomato bisque. I would definitely come back! The fries are all natural and very tasty. The java porter was also perfect.

This was one of the only restaurants open at 11:15am on President's Day, so we gave it a shot. Really enjoyed the decor and style of the place itself, plus they made some damn good bloody mary's. Unfortunately, our food was staggered and I ended up waiting 5-7 min after my boyfriend had finished his burger to get my grilled cheese (which, also unfortunately, had been ordered wrong). Pretty inconvenient that they didn't take any cards, either. Our server was okay but not very attentive and sounded like he was half asleep (maybe that's why my order was off...).

Great food, great service. The waitress was very helpful and honest in assisting us with our dinner choices. Food came out fast. Make sure to bring cash or check before coming though.

Atmosphere, staff, and food - all 5 stars. In addition they have live music (at least on Sundays), gluten free bread, and free samples of beer! I think I tried 5 or 6 different beers before picking one. Our guy really knew his stuff and loved what he does. The French fries are a must - do not leave without getting some. We both got sandwiches, and they were perfection. The burgers, chilli, burritos, and basically everything on the menu looked amazing, including dessert. If I was a local, this would definitely be a spot I would go to regularly.

Chris W.

Love this place! We almost always hit the Mountain Sun or the Southern Sun on our way home from Skiing. Nothing beats an FYIPA and a junk burger with fresh cut fries when you're tired and hungry. It's always worth the wait so be patient and order a pint to enjoy until a table opens up.

Excellent service. Went here with a buddy while on vacation in the Centennial State. Arrived at MS at around ten p.m on a Tuesday night. We had just spent about nine hours hiking in Rocky Mountain National Park, got caught in a huge storm and were in desperate need of food and drink. As we were seated by the hostess, a gentlemen who I believe was the manager/owner, informed us that the kitchen was closed and asked if that was a problem. Bummer. We informed him that we indeed had come to chow down. He was kind enough to have the kitchen remain open for our orders, which is above and beyond in my book. My buddy ordered the speakeasy steak sandwich and I the S.O.B burger. Could have been that we were famished, but our plates were awesome. Everything tasted fresh and as others have noted, the fries are great. Also, ordering a burger medium rare and actually getting a burger medium rare was nice. It seems like many restaurants have a problem understanding this concept, God help us. My buddy's plate came with a cup of soup, and while I can't remember the name and I didn't try it, it consisted of veggies, Italian sausage and a tomato-y broth. It looked delicious and he said it was bad ass. Our waitress was very sweet, professional and helped us pick out one of their awesome brews. The cash only policy of MS almost became an issue when we were trying to pay our tab as we only had cards. The owner/manager? did something unbelievable. He said we could mail him the cash. Whaaa? That kind of customer service is unheard of in this day and age. Granted, we went to the ATM so we could pay the man, but his approach left us both very impressed. Keep up the good work, Mountain Sun. I would love to come back if I'm ever in Boulder again.

I absolutely love this place! They have great vegan options and it's a very chilled out atmosphere. You seat yourself and they work off of a team system so you don't have to rely on one waiter. You do, however, have to pay in cash or check (there's an ATM in the restaurant) but if you don't have either they'll send you home with a stamped envelope to mail in a check later on. The food is delicious (best black bean burger I have ever had!) and they have an incredible selection of beers!

Phil N.

I'm from Pittsburgh and just moved here. I sat in by myself, was greeted by the manager and we talked for a bit about the food and beer. He didn't seem the slightest bit rushed and answered all of my questions. I didn't realize he was the manager, and said that I'd start with the cream stout. Shortly after I was greeted by my server, and we had another good conversation. The manager then brought me the beer, told me it was on the house, and said welcome to town. I know exactly why I moved to Colorado now. By the way, the Asada Burrito is perfect. I can't wait to come back, and I haven't even left yet.

Mary K.

I'm lovin the Mountain Sun. Great staff! Thanks so much to the waitress who bought us a round of drinks because we were from NY, so sorry we didn't get a second round! Burgers were out of this world. Free fries instead of bread which was AMAZING. I will definitely return next time we are in Boulder!
(5)
Crista H.

The service was pretty good, the food and drinks were also really good. However, the reason I'm rating this a 4 instead of a 5 was the price we paid for our half order of nachos which I thought was ridiculously over priced. Yes they were good, but not $11 good. A full order is $12.75, and a half is $10.75, for literally half the size order only saving $2. If I would have known that, I would have just paid the extra $2 and got twice as much. $8.75 is a good price, but not $10.75. Lower your price! I did mention it to a waiter, he agreed, but did nothing about it.

How can you not like this place? I'm not even a beer person, but I always find one that I end up liking. The only issue I've faced is the wait, but it's completely understandable.

This place is amazing!! We walked in at a very busy time and they were extremely friendly and fed us free samples of beer and fries for our group of 7. Every server was very friendly, the beer was awesome and the food was excellent!! If I could give it more than 5 stars I would. Love this place and will come back again and again.

Reyana F.

randomly yelped this place while i was waiting for my friend to get out of work and it was amazing. from the outdoor seating that still felt casual, to the homemade hummus and the impeccable service, my boyfriend and i had the best experience! the break down: service is extremely friendly but definitely the typical boulder friendly guy who knows his beer and looks somewhat like someone famous. the food is like typical bar food but super delicious (junk burger and you won't be disappointed). they also cut our burger in half for us! maybe i've been in SF/NYC for too long, but i loved the friendliness and laid back vibe of this place. pitchers of FYIPA are a must.

Nima A.

Excellent burgers, incredible beer. The ambiance is so local and fun feeling. This place is really killing it!!! I came here on a triple date with a group, and we had a blast! We all ordered burgers and a few pitchers of delectable craft beers. All was great and we had a blast. Service was excellent as well. The reason why I gave four stars rather than five is because this place is CASH ONLY. Major pain, especially for a sit-down restaurant in this day and age. It doesn't help that I'm an accountant. Cash-only = up to no good in my (and the IRS's) eyes.

SO COOL! I couldn't stop studying the beautiful artwork on the walls. Employees were SUPER friendly, beer was excellent and there was a great crowd for a weeknight. Didn't get to try the food, but that's an excuse to go back.

My friend from Atlanta came to visit and we decided to dine here since the yelp reviews were great. It was packed in a Friday evening and we waited about 20 minutes for a table. They were so busy, but everyone in the staff made sure we were well taken care of. I ordered a Bloody Mary which was just average. My friend and I both wanted to venture out and order something that sounded a little crazy. So we both got the Date Night Burger. Thank goodness we did because it literally was the best burger we've ever had! Their fries are also wonderful because they cut their own fries every morning.
(5)
Shelly D.

Love this place - plenty of veggie options and endless beers on tap. They even have a "karma envelope" since they only take cash or check. If you have no way to pay for the bill, they'll give you this envelope and you can mail it in! They said they have a 99% return rate on those checks! Fantastic idea! I heard they have bluegrass on sunday nights, will check that out soon!

Erica F.

We were referred here by the Prana store employee down the way. Since he was a "local," we asked his advice on stuff to do in Boulder the day we visited. Mountain Sun was a solid recommendation! The vibe as soon as we walked in was welcoming and homey. It was only 5pm or so on a Tuesday and it was so busy! The manager/host seated us right away and we were immediately approached by a waitress. At no point were we made to feel like they were too busy to deal with us. We got our beers quickly and ordered some cups of chili and soup. Both delicious! Homemade soup is the best in the rain. Prices were very reasonable. This place is a must-visit in Boulder. Thanks Prana guy!

We came here on a Sunday night after a long drive from Aspen, and were immediately greeted by a very friendly waitress who led us to our choice of table. The place was huge, could easily have a large party there! We were handed beer menus and left to deliberate on the massive amounts of beers they had on tap. We were lucky enough to come to Mountain Sun during Stout month, where they had a ton of different stout beers on tap. Seriously the most delicious stouts I've ever had! The waitress was extremely friendly, she offered us tons of samples/tasters before we decided on which beers to buy - very generous pours of beer. I tried several stouts, coffee/bacon/chai tea/peanut butter. I liked the chai tea stout the most, as it hd the most unique flavor, but honestly all the stouts were very high quality. We ordered wings, which were delicious and a very large portion for a group of 4 to share. This place has seriously some of the best beers on tap and i would definitely consider coming back here when i am back in Boulder.

Great casual spot in Boulder with super friendly service, good beer and awesome food. I'm in town for work and looked up a cheap spot in Boulder that served beers (lots came up) but I'm glad I selected Mountain Sun Pub & Brewery. My waitress was great and we talked about beer quite a bit and she gave me a small beer sampler before I chose which pint I wanted to order. I got the bison burger with fries and it was delicious. I could have made a meal just on the fries so definitely get those.

Kippy D.

Yes, it is that good. The server let my sister and I sample a few more beers, small samples and we finally found a couple to settle on. I had the eggplant parm sliders, so freakin good, I wanted to cry. Sis had a bison burger, that's what she was in the mood for. It had bacon on it. She wanted to cry too. So incredibly good.

Kevin K.

Probably the best beer in town (and that is saying a lot). Mountain Sun usually has 10+ homemade beers on tap and they are first rate. The food is pretty good (slightly hippy, slightly burger joint). Some folks love the food, but I think the beer has to be the reason to go! This joint is often CROWDED! Especially after 5pm. Be ready to stand around drinking a good beer for 45min to 1 hour while you wait for a table (if the beer wasn't your goal to begin with). The fact that its crowded reflects that it's good stuff in a small restaurant. The wait staff is nice. You can ask any employee walking by for help (or more beer) and they'll get it for ya. Be ready, this place is CASH ONLY!!! They have an ATM you can use, but as with all non-bank ATM's be ready to eat some fees that add up if you don't have cash.
(4)
Lori S.

Great food and beer. Unique all around. I had their eggplant sliders on sweet potato buns, delicious! The arugula, feta salad that came as the side was excellent. Wish I could have tried more of their beers. Next time I would order their six beer sampler. Full house at lunchtime on a Monday says this is a favorite place for locals. Note that they do not take credit cards, but there is an ATM or they will trust you to mail in your check!!
(4)
Steve S.

Definitely a cool place to go on a weekend night just because of the atmosphere. This place was packed! This isn't a traditional pub; more like a hippy drum circle that also serves beer and food. I find that atmosphere comforting, don't you? The beer is cold and tasty, to match the pub-style meals. Don't expect Frasca Food and Wine, but do expect meals better than your normal pub or sports bar. One little note - Mountain Sun does not accept credit or debit. So cash up otherwise you'll be staring at other people's food.

ONE CAVEAT TO START WITH!!!!!!!!!!! This place doesn't accept credit cards. But they don't make that clear up front. Extremely bad policy- the server should tell the customers right at the beginning. Why don't they make it clear? Because the place makes more money that way. How? If you find out at the end of your meal that cards aren't accepted, you can use the ATM in the place to get cash. The catch? There is a $5 service fee for every withdrawal. MS is making money hand over fist just from that darned machine. Kind of unethical. Payment policies aside, this place isn't bad. Nor is it particularly good. Since it is a brewery, I'll start with the beer. We tried the Brewery Taster, which consisted of 6 small pours of 6 different beers of our choice. They were all warm. A negative right from the start. As for the quality and tastiness? Eh. We've had much better beers at many other local breweries. This place ranks far down on the scale. Won't return here for the beer. Won't return for the food either. It was entirely average. Sweetie had the black and blue burger, ordered medium rare. It came out well-done. The blue cheese didn't taste like blue cheese. It simply tasted like a horrendously salty mass of something unidentifiable. The blackened seasoning didn't taste like anything in particular, nor was it particularly good. I had the buffalo chicken sandwich. Same blue cheese (or, should I say, same salty non-blue cheese). The chicken was way overcooked. Not very good at all. The service was extremely odd. I'll give MS kudos for attempting to have good service, but, oddly, their efforts fell way over the mark. Multiple (3) servers were assigned to help us throughout our meal. I'm sure that this policy was created with very good intentions- an attempt to ensure good service. But it backfired. For instance, we placed our drink order with one server, and then in the next few minutes, each of the other 2 servers came by to take our drink orders. We had to tell each of them that we already had been helped. Same thing happened when we ordered food. (There clearly was no coordination of any kind between the 3 servers.) Then, throughout the meal, each server came over numerous times to see how things were, and if we needed anything. Again, very good intentions. But what ended up happening was that literally every two minutes, someone was coming to the table. We couldn't hold a conversation. After about half an hour of this, we simply wanted to get out of there. We left a very good tip, based on the good intentions. But by the time we left, we were kind of twitching when someone approached the table for umpteenth time.

Upon entering Mountain Sun, you are told to sit where you like. I arrived before lunchtime, having a feeling that the place would fill up quick at peak hours. That was smart on my part, as it did. While eating you are helped by a rotating cast of employees. This is unique, and assumably helps to provide timely service. It allows the patron to have a little face-time with many of the servers buzzing about. Its nice, if not a little impersonal. There is an amazing selection of local craft brews on tap. The servers have educated and personal suggestions. The food caters to just about everyone. I ordered the vegan ruben out of curiosity. It was a solid B, if I was a vegan, I am sure it would score higher. It is of note that they only accept cash or local checks. Thee is an ATM on the premises with a low-enough surcharge. Here is the thing though, (and this really is the thing), they offer the patron-in-a-pinch the option of mailing payment for the meal via mail. Furreal. I was offered the option upon seating. Thats fantastic. So rarely do you actually feel trusted by the establishments you frequent. This reviewer concurs with most of the others; Mountain Sun feels like home. A must frequent and a welcome alternative to the pricey and impersonal options in the downtown Boulder area.

First time at Mountain Sun. The atmosphere is very relaxed and friendly. The menu is broad and caters to all appetites. My Bison Burger was cooked to perfection with crispy bacon. Their bbq sauce is perfect, sweet enough without a overly vinegary flavor. My friends had the Boom Boom Sandwich with bacon and absolutely loved it. The S.O.B. Burger was cooked to perfection and the bun didn't slide off even with the jalapeÃ±os. Fries were fried wonderfully and weren't skimped upon. While they don't accept credit cards, they have plenty of work arounds. Overall, a fantastic experience with great beer and a perfectly mixed Moscow Mule.

Bill C.

My wife and I have never had a bad experience and Mountain Sun/Southern Sun. If I had one quibble, it's that getting a seat at Mountain Sun can be tricky, due to its smaller size. We usually go to Southern Sun, where its easier to get a table.

I LOVE Mountain Sun! I went back to Boulder last month for a visit (I am a former CU student) and I planned to eat at Mountain Sun in advance. It was just as good as I remember. Our waiter was Tokyo and he was so awesome! He was attentive, knowledgeable, and was truly passionate about MS's beers. He made some excellent suggestions and continued to follow up with us to see if we were enjoying our meal. He also made us laugh really hard (something about a polenta special... I wonder if he remembers :) ). I love spending time at MS because it's a really positive and laid back environment. You can tell that they have a lot of regulars and everyone is beyond friendly. All that and I haven't even talked about the food and the BEER! Their chicken quesadilla is perfect, in my opinion. It's not your run-of-the-mill quesadilla that's overstuffed with cheese - it's proportions are perfect and the ingredients are fresh and SO tasty. The salsa on the side is so delish! The beers are beyond excellent. Be clear with your server as to what you like and they will take good care of you. We did a flight and chose a few ourselves but asked Tokyo to throw a few of his favorites in there too. The ones he put in were probably our favorites. You can't go wrong!! Excellent service, chill environment, delicious food and super reasonable prices. MUST TRY IN BOULDER!!

To be fair, I'm not a big beer drinker so this review is about their food. I had a burger and fries. It was okay but wasn't memorable and was greasy enough that it upset my stomach. I also tried their carrot cake and I must have gotten a bad piece or something because it tasted stale/old. I will say that my beer drinking friends do love going here.

Place to go for local craft drafts, the food is ok for vegetarian selection. Good prices, this place does not take credit or debit cards. ATM in the back, if you wanna pay to get your money. Bring your checkbook if not~
(3)
Bill C.

I would normally give three to four stars to a place like this that does have good food and beer. The service was fair to slow with different things forgotten that we ordered. BUT THE BIG ISSUE IS "WE ARE CASH ONLY". There is no sign and no mention of this until you pull our your credit card to pay the check. Then they tell you there is a cash machine in the back you can use. Stupid and deceptive is all I can say. We will NEVER be back. Too many other choices that are just as good if not better.

Anthony E.

We walked in and noticed the sign to seat yourself to a clean table. Given it was lunch time on a weekday there were no tables available. With hungry kids we decided to step out and yelp other restaurants. Then one of the waitresses came out and greeted us to come back in and that they would arrange a table very soon. So glad they could seat us because it was "Stout Month" and wanted to try out their beer. Had the "Oatius Prime" and their "Stoked Oat". Customer service was very friendly and the Patrons were awesome too. We ended up sharing a table with a couple of my distant Work Colleagues which was pretty cool. Definitely recommend this down to earth establishment for anyone visiting from out of town or for a simple bite and a beer ;-)

Ron R.

Super friendly / efficient wait staff. First time this week. Came in from article on stout month. Fun sunny outside seating. Busy noisy inside. Fun. Had nicks famous hamburger. Was good. Bought a flight of 4 house stouts. For my taste Megatron stout blew my other 3 stouts off the map. Had one of their nitro stouts. Still a left hand man. Cute fun cool rockin brew pub. Just as they all should be. Go. You'll have fun.

Lana S.

Not as impressed as others. The place does have a great atmosphere, lots of young college kids. My broccoli cheddar cheese soup was A-OK, it lacked the creaminess one would expect from that type of a soup. The sourdough bread in my sandwich was not fresh unfortunately. The chicken and veggies in the sandwich were awesome though, but overall the food was lacking in taste and flavor. My boyfriend's burger was plain and boring. The french fries were soggy :(. On the other hand, our waiter was awesome, very knowledgeable, super friendly and attentive. So five stars on that.

This is, without exaggeration, the friendliest place I've ever dined. I was shocked by how nice, accommodating, and attentive the staff is here. I wish I could move to Boulder so I could come here all the time. I got the Bison Burger and it was great. Everybody I was with loved their food. The fries are amazing, especially when dipped in the ranch/buffalo sauce, which we did not ask for but the server just brought it out because it was his favorite. Come here.

James C.

This place is awesome. Our waitress was so friendly and so interested in getting us to enjoy their beers. The first thing she said was that we can sample anything for free and seemed disappointed when we knew what we wanted immediately. When looking for a second beer I asked to sample two other beers and instead she brought me 5 more to try. My friend ended up sampling about 7 all on her insistence. The food was fine, I did t think anything amazing but it was definitely satisfying after a day of climbing. They have a perfect fry policy which is pretty cool. I didnt think their fries were exactly how I like them but it's just their style I think -- no need for a redo. Anyways I really enjoyed my meal and drinks there (oh, the beer is quite cheap during happy hour). I pulled a half star because I wasn't amazed with the food but it definitely wasnt something that would steer me from the location again. EDIT: I've been to Mountain Sun many times since and it really is a great place. I still think the food isn't amazing but it's good and satisfying for sure. The service here is phenomenal though. The servers love beer and love helping you find beer that you love (and they have plenty of good ones). I would say this place consistently has the best service of any restaurant I have been to in my life, regardless of price. And for that reason, I am changing my review from 4 stars to 5! This place would rank high on the top places to eat, anywhere.

Megan S.

We enjoyed lunch at Mountain Sun after a morning flight. What a welcome to Colorado! A friendly server directed us to the beer tastings and specials menu. The pork specials (sandwich and platter) were wonderful- flavorful with a nice amount of spice. The fries were perfect, some of the best I've had anywhere. A great start to our long weekend in Colorado!

Travis C.

Absolutely love this place. The wait list is at the bar, so it's easy to enjoy a beer while waiting for a table. The restaurant is stocked with books and board games to play with friends over a beer or while you're waiting for food. The staff is very friendly too. Just remember, no credit cards! Cash only.
(5)
Kurt L.

A great place. The wait staff is friendly and courteous and the food and beer are great. Two things wrong with this place, though. The first is not that it's CASH ONLY, which isn't a bad thing, but that there are NO CONSPICUOUS SIGNS AT THE FRONT INDICATING IT IS CASH ONLY. So, if you're not aware (as was the case with me), you could sit down, have a great meal, and then find out you have to go to the ATM in the restaurant, pay exorbitant fees, and pay your bill. The second is that, while the wait staff is great, the service is INCREDIBLY SLOW. Other than those two, great place.
(3)
Brittany S.

We loved this place! Great service, great food, and great beer. I really liked the FYIPA. We had to wait a couple mins for a table, but they made sure we had drinks while waiting. One thing we didn't know beforehand--they are cash only! This caught us off guard and I'm so glad I just happened to have cash.

Lori C.

We were in downtown boulder on vacation and didn't know where to go to grab lunch. After reading the reviews on yelp, we knew this was the place. We were greeted right away and since a table wasn't ready, they suggested we head to the bar for a few free samples of their brews while we wait. You could tell that the bartenders and wait staff definitely enjoyed their jobs... they were laughing and joking with each other and the customers. I finally decided on the Date Night Burger (pablano peppers, bacon, goat cheese and date puree) and it was fantastic! I definitely recommend this place - between the food and the atmosphere, it was a hit!

I was in town for the week visiting my sister and her fiance took us here. The burgers were excellent, fries amazing, beer selection top notch. I can see why this is a local favorite. We came right before the lunch rush so we didn't have to wait long to be seated. Nice place and I would definitely come back here if I lived local.

Wonderful experience!! Crowded, but found a table right away. Very friendly staff and overall great vibe. Awesome beer selection and the good was amazing. I only wish I had room to eat it all. They have great deals and also games to play at your table. Don't have cash or a check? Ask for a karma envelope! Pay later!

Every time we come to Denver we make Mountain Sun a must-visit. Excellent food, beer, and service! You can't go wrong. Love the fact that they are always changing things up and have daily menus.

One of my favorite places ever. Amazing beer. Resinous Rye brewed on-site is my favorite beer. FYIPA is known to many far beyond Boulder. The food is terrific. The atmosphere is awesome. Just go - you will enjoy yourself, unless you are a soul-less stuffy jackinape that simply cannot have a good time.

Busy busy. We really liked the beers here and the vegan burgers were good. It was very crowded and loud, but that was fitting for the environment of the place. Doesn't have much standing room or a bar area and I would feel guilty taking up a table just to drink. Otherwise, great place!

Thoroughly enjoyed this place from the service, to the beer, to the food. Im a fan. Worth waiting, worth paying in cash, worth a few workouts to burn it off. All in all I round up a 4.5 to a 5 and will be back!

Mountain Sun Pub & Brewery is a loud, cash-only local brewery that brings to mind the 90's Smash Mouth #1 hit "Walkin' on the Sun" with it's iconic twist of hippie ideals suburbanized into commercial success. Mountain Sun is a micro-brew where every employee does every job and you'll find a menu of vegetarian & healthy choices mixed with classic American burgers and Mexican burritos. And they folked out with guitars around a bonfire Just singin' and clappin' man what the hell happened The "Team Service" concept works as we rarely were without someone checking in to help. Of course, half the time, we simply said someone else was already "handling it." Hooray for a co-op that actually succeeds in meeting the needs of all. You might as well be walkin' on the sun One of the "friendly many" offered to bring some free samples of beers to help choose which one matched our moods. We sampled Free samples of Blackberry Wheat, Colorado Kind Ale, Illusion Dweller I.P.A., FYIPA, and Quinn's Golden Ale. Olivia Z. got the Blackberry Wheat while I had the Illusion Dweller IPA followed by a Colorado Kind Ale. There is definitely a beer or four here for everyone and with free samples, how can you resist? Well, my mom the rebel can and got a red wine since she's not a fan of beers. It ain't no joke I'd like to buy the world a toke And teach the world to sing in perfect harmony Oliva got a bowl of the Vegetarian Black Bean Chili ($3.95) with the Cheese add-on ($1 extra). It was gooey and thick though a tad too sweet for real Mountain Men. We split an appetizer of The Pub's Famous Fries (Med. $2.75) which are fresh cut and served hotter than the sun. They needed lots of salt, so, we added plenty of sprinkles for some flavor while eating them carefully not to burn our fingers or tongue. My mom's order of the house specialty Tim's Blackened Chicken Quesadilla ($8.50) was as tasty as it was huge. They brought a large plate with covered with guacamole, salsa, and a half-moon of quesadilla. It was the perfect size until the server said he'd bring the other half once we finished this one. What other half? Yikes... we better share. She ate half and we ended up getting the rest to go. For me, a burger was calling my name so I answered with the Jalapeno Burger ($8.00) and an extra side of Green Chilies ($1.25) for some kick. The bun was too trivial while the 2/3 lb. of beef was parched. Luckily the chilies and cheese brought some moisture to the sandwich. A-ok, but not groovy. And if you follow there may be a tomorrow But if the offer's shunned you might as well be walkin' on the sun I'm a much bigger fan of Mountain Sun Pub & Brewery than I am of Smash Mouth. The brews were brilliant, the service was synergetic, and the food was filling. We left quenched and headed back out into the Rocky Mountain sun to enjoy the rest of our evening. You might as well be walkin' on the sun.

Really cool relaxing place. The have great food and a nice selection of beer. It is loud but everyone is friendly and it's generally just a good time. They also don't accept credit cards, but they have an atm inside so it's really not a big deal.

Tricia K.

After a day on the slopes this place hit the spot! Quality food at a reasonable price. They had a great teamwork philosophy in full swing. You can pretty much trial any beer on their lost for free. The kids menu has a good selection at great prices.

They have the NICEST staff ever. Every single person that we talked with was just so nice! It was a beautiful day and the restaurant was packed for lunch. We put our name on the list and went back to the bar to get a beer. At the GABF the night before we had tried their Big Boi Bob Imperial Chocolate Stout so I was happy to get a full sized serving while we waited. Delicious!!! Once we were seated we had another nice server. Out of this world nice! We ordered the pub fries, the spicy chicken burrito and a burger. Unfortunately it took quite a bit of time for our food to come to us. We ordered the fries to come out before our meals. The fries were great, but our entrees came out so quickly after the fries that I felt overwhelmed with all of the food on the table. My burrito was good, but I wish I would have gone for the green chili instead of the red sauce. The sauce was a bit bitter and I ended up just wiping it off my burrito. The inside of the burrito was tasty and the serving size was HUGE. I could have easily split this with my date. I ended up just mostly eating the inside of the burrito because the tortilla got a little crunch on the end and made it a little difficult to eat. My date loved his burger and wiped the plate totally clean. I would definitely return, even if just for a beer and fries! Why can't every restaurant be as friendly?!

We stopped in for lunch before heading to Denver to fly home. I had the steak sandwich and my husband had the Mexicalli burger. Both were fresh and delicious. We also sampled and drank a few beers. Every things was great. I would come back. Very friendly and attentive staff!

I had a special which was a fall veggie wrap and it was delicious. Very fresh!! My husband had the tomato bisque soup and a sandwich which was also very delicious. We really enjoyed our experience here and would highly recommend since it is a little off the Pearl Street Mall but not by much.

While the food is better than average, the server took forever to do anything. Even bringing condiments for our food took almost 10 minutes and it wasn't busy at the time. :-(

Good people, good brews, good bands (when they have them). All around friendly down-to-earth wait staff. We didn't order any food, so can't speak on behalf of that. One warning: the crowd is super young (early 20s)... But all in all, great spot to hang.

Michal F.

The hippie decor jumped up and hit me in the face the second we walked in. Whimsical seems too unforceful a word, your assaulted by murals of laughing sun & moon symbols surrounded by a earthly paradise. This is the type of place you expected from Boulders independent reputation and its authenticity seems irreproachable. Beer is brewed in-house and has depth to satisfy staunch beer snobs. I partook of a night colored libation boasting of high ABV, there was no doubt in my mind the match was pre-ordained as I felt myself relax in its enjoyment. I also tried the Junk Burger(5). The patty seemed generously round and thick I would guess 1/2lb. Bacon crisp and cheddar sharp. I took this one from the servers recommendation and clearly he knew me well. A required stop when i visit Boulder again.

Teri S.

By far the coolest beer place I visited in Boulder. I felt very at home there. It was a friday night and every inside seat was full but there was a streetside bar on the sidewalk. I asked some people who were local what I should try, they made suggestions. My waitress let me try 4 beers ( generous tastes too! ) with no pushback. I settled on the Pater's Belgian. Good choice. I then tried the Colorado Kind ale. They had an amazing beer list to choose from. I really liked the service concept here , everyone does everything. I had different servers, but they kept my order with me, not the wait staff , so for example I was like" I want to try that second one I tried, I dont know what it was called" and the alternate waiter says ." it's written down right here - in order " YAY They are cash only, but there is an ATM in the back that only has a $1 charge. I did not try the food. Will next time. Great staff, great beers.

Thumbs up on the food, thumbs up on the beer, thumbs down on cash since I never carry it... but I'll still give it 5 stars.

My husband and I were driving from Denver to Estes Park by way of Boulder and decided to stop here for lunch based on Yelp reviews. The place was packed when we walked in so we waited at the bar where the staff was incredibly kind and helpful. My husband and I tried almost every beer they brew and the staff was so kind. We ended up with the FYIPA and the Tripel both of which were delicious. We had burgers for lunch and they were wonderful. The fries were so good! The kitchen made some extras and they gave them to us for free while we were waiting at the bar. We only ate a few before we sat down and they were so good that we added more to our lunch orders. Great spot!

Alicia K.

I love this place! It's one of the first places I ate at when I first moved here. I've been meaning to write a review for it as it's been burning a hole in my metaphorical yelper's pocket! Consistency is so important to me and I'm consistently satisfied every time I come here. Anytime I have a visitor, I make a mandatory trip to Boulder to take them here. The wait for a table? What wait?? There's really no wait when you get to sample all their beers until you settle on one in the back at the bar. IPAs! So many IPAs to choose from! It's IPA paradise for me! The bartenders are quick and friendly! They're never resting and always pouring! When we sit at our table, we order a basket of fries - pretty much devoured right after they are set down... And I just can't help it. I try to be adventurous (monterey chicken, burgers, gooney bird..), but ever since my first time at mountain sun, the spicy pollo asada burrito is just the thing for me (hold that sour cream! and spicy red sauce on the side please!). I love spicy and boy can that red sauce get spicy! Technically, I've tried most of the burgers...I "tax" my visiting friends with a bite of theirs..you know, just to make sure everything was prepared ok. And those burgers always are! But in the future, I'll still need to taste test... just to verify... Amazing service here! If you've ever read any of my reviews, you'll know that poor service is a pet peeve of mine and I really don't think there's any excuse for it. This is not an issue here. It's always crowded and I'm ALWAYS impressed at how attentive my servers are to me. I remember once they forgot to put the spicy red sauce on the side. I didn't even mention it to the server (no big deal), but the manager noticed and personally came by and said "we're so sorry! do you want a new one?" I appreciated that he took the time to try to fix the error. I declined, seeing as the burrito was still utterly delicious (I just had a few extra beads of sweat). He comped my beer - no complaints here! Hmm...maybe it's time for a trip up to Boulder soon.

Mountain Sun is easily one of the best breweries in boulder. If you are looking for a great IPA, come no farther. They always have a great seasonal selection of many different beers on their menu and they are reasonably affordable. I also really like the food. Their burgers are very good, I highly recommend the Junk burger with an upgrade to fries and a sampler of different beers. Cash only.
(4)
Joseph S.

Food is good, beer is really excellent (especially the FYIPA). The only problem is it's too noisy to hear the person next to you, so sit outside if you want to talk and it's not too cold.

Ashley W.

Loved this place! Being from out of town, i don't know that we would have found it without Yelp. It's on Pearl Street but a bit further down from the crowds and action (not a bad thing). I love the relaxed hippie friendly vibe. The food. beer and service were all excellent. I got a steak salad (daily special) - grass fed local beef, crisp peppery arugula, blanched green beans sourced locally and pungent bleu. A classic combo but very well executed with high quality ingredients. The beer was really great and I'm not a big beer gal. Per our server's recommendation, I did a half and half ginger beer and blackberry wheat. Very unusual. Highly recommend whether you are visiting Boulder or a local.

People love it, but I don't. The lovers are bearded, tshirt wearing, beer loving, slightly troll-like, climbers and nerds. Not a bad demographic, but I fear that they have low standards. Mediocre food. Board games are fun. Very friendly staff. Great beer!

Amy U.

I might move to Boulder, just for this pub. Though it's rather small, it's still welcoming and I was lucky enough to stumble in on one of the last Stout Month nights. Holy hops- damn good beer. Damn good food - fish and chips 5 stars. Chicken quesadilla 5 stars. Even their CURRY (wtf?!) was great. Their fries are addicting, and all the pints are generous and cheap. I could live here. I just might. Be warned - all you weenies that can't handle a loud pub, don't ruin my night coming in here! It's elbow to elbow, loud, and every one is happy - NOT like a CA place. Spread the love, pass the beer.

My wife and I were on vacation in Denver and decided to take a trip up to Boulder. I saw this brew pub had a great review on yelp and we decided to pop in. The place was packed, and it offered samples of their new summer brew if you wanted. We were seated quickly and I ordered an FYIPA to start off with. It took awhile to get there, but I was pleasantly surprised with citrusy happiness. The menu was pretty extensive and pretty organic. Kind of a college hippie, all natural place. I ordered the tempeh rueben beer baked tempeh with sauerkraut, melted Swiss, tomato, vegan 1000 island on rye bread with chips, I substituted a side salad for like two buck for the chips. Love when I can sub a salad! Tempeh is a soy based product, but more in a loaf form than tofu. It was plenty tasty though! Everything about it would be a vegetarians delight. I had the XXX pale ale that was on tap with my meal, which was also real good. Just above average. Overall, a fun place for dinner. Lots of families and college kids enjoying their supper. The prices were very reasonable, and I would definitely take someone visiting back here.

Had a Fantastic experience here the other day. Was visiting Boulder from out of town (Iowa), and had been here one time previous a couple years earlier. To make a long story short, I'll break it down by bullet points. -Had about a 10 minute wait to be seated, was given free french fries while waiting. -Great selection of craft beer, waiter bought us first round since we were both from Iowa -Food took about 25 minutes (which was completely acceptable to me and my friends considering how busy they were that day) - Manager determined food had taken too long, gave us 50% off our bill (we assured her that the initial free beers were more than enough to make up for a slightly above average wait time, but she insisted) - Maybe the best burger I've ever had (Date night burger) - Manager came back later and told us that she had thought about it was going to take care of our entire meal (100% comp). We were shocked. I had never seen anything like it. We told her again and again that it really was not a big deal at all, but they insisted on not letting us pay for some of the best food I have eaten in a long time. HIGHLY RECOMMEND to anyone who likes great food good and equally delicious craft beer, with an amazing staff who prides themselves on A+ service. I will be returning to Boulder just to visit this place, if nothing else. BLOWN AWAY

Lindsay K.

Really, truly, amazing customer service. I cannot say more about the quality and friendliness of their managers. We had a snafu with our order the other night (we had to wait about 35 min, the kitchen lost our order) and our entire meal was given to us for free. None of us even complained about the wait. Also, epic burgers.

Binal M.

We were on our way home from a long hike@ Rocky Mountain . After reading the reviews we stopped by at this Pub. I loved the easy going hippy vibe with eclectic decorations. We were waiting on a table and they asked us to sample some Beers. The server was really information and surely knew his beers. They asked us to try couple of beer and absolutely didnt want us to settle for something we didn't like. Once we selected our beer he figured we are newbies and offered us free beers.. btw who does that? (shhh...). We were completely happy with our entree. I had a Chicken burritos with green chilli.. the green chilli was off the hook. We had 2 beers and 2 entrees+taxes for about $21.. totally worth it!! will do it again in a blink

Rachel A.

Mountain Sun, for me, is the heart of Boulder. Perfect atmosphere (they've even got board games!) with lots of fun art, amazing beer (including 8 oz beers -- perfect for me), and of course, terrific food (try the Date Night burger!). They'll also let you try as many samples of beer as you can handle. Only down side: it gets really, really crowded, especially weekend nights.
(5)
Janette G.

Awesome! Awesome! Awesome!!!! What a great customer experience! Free beer tasting. Wonderful beer! We sat down to order and was studying the menu and it said "cash only". Oops. No cash. No problem... There's an ATM.... except my boyfriend couldn't remember his PIN. I was quite frustrated bec I remembered asking him whether I needed to bring cash. The waitress old us tongi ahead and order. She will send us home a "Karma envelop". Basically send a check when you get home. What?!!!! A place of business that does that should be commended! Did I mention that the beer was amazing?
(5)
Kate M.

Mountain Sun has been making the best burgers and beer in town for twenty years. Going into Mountain Sun feels like coming home. Relaxed atmosphere and unparalleled service. The waiters and waitresses are genuinely enthusiastic and attentive. The date night burger is what my dreams are made of: date puree, peppers, bacon, and goat cheese. The make the BEST fries in town. As for the beer, the variety of styles in incredible. Mountain Sun was one of the leaders of the craft beer movement. They know what they are doing. One of my top five restaurants in town. Yes, that's right, I would take it over Frasca any day,

Gotta love the combination of good beer, good food and a great location. Easy to get to from Pearl Street, Mountain Sun offers a great escape. Their menu changes regularly depending on what is fresh, and their specials are usually the best route to take. It can be crowded, so I would recommend getting there early to beat the rush, but Mountain Sun provides a great laid back atmosphere to meet and talk with some of the Boulder locals over a great brewed in-house beer selection.
(5)
Alex P.

Took my parents here when they visited so they could get the true Boulder experience. They now affectionately refer to it as the "Happy Hippy Place." Often a long wait for a table but with the friendly staff and tasty brews, the wait is certainly beerable. With the communal service I felt I've never been neglected; also interesting to see the brew master cooking. That said, the food isn't at the peak of gastronomical sciences... it's simple and good.
(5)
Song S.

Everyone here is friendly and the place always seems to be bustling . There's a bar in the back in case you're waiting for a table or like us, you just want to stop in for a drink while walking around town. They'll let you taste what is on tap, which is great for the indecisive. But the bar is pretty tiny, watch your elbows.

Rick C.

They don't take credit cards .... odd? The beers were good but not outstanding. Wait staff very attentive and knew how to describe the various beers they produced. Old building = nice ambiance. Also, a nice place to watch people both inside the facility and walking by on the side-walk.

Delicious burgers and loved their Raspberry Ale (and I don't usually like beer, so that's saying something). Had a great time playing yahtzee while waiting for our food in one of their booths. Loved the food, the staff, and the atmosphere. (for those of you with children, it was definitely family friendly) Well done, Mountain Sun!

The beers were great. Everyone at my table enjoyed their different brew. The food was great as well. Burgers all around and they didn't disappoint. We waited about 15 minutes, worth the wait. The oven wasn't working so we couldn't order the nachos but other then that we really enjoyed our lunch.

This small joint definitely has that hippie vibe; with the crazy psychedelic decor, board games to play while you wait and waiters with dreadlocks, but they were super friendly and the food was VERY good! I got the burger and fries and would highly recommend it. While it wasn't as good as Park Burger in downtown Denver, it was very juicy, well seasoned, and bursting with flavor. I definitely recommend checking this place out if you are anywhere near the Boulder area!

Dave C.

This place sucks! The beer is vastly OVERRATED, I can think of at least a dozen microbrews that put this beer to shame. The food was just awful. Fries were not even close to cooked enough, just incredibly soggy. I think I've had better fast food burgers than the flavorless burger I had here, plus the bread was stale. The service was abhorrent. The servers were very rude, almost acting like their night was ruined because there were customers in the restaurant. To top it all off, I'm suspicious that one of them spit in my beer. If you are thinking of eating/drinking here, save yourself the trouble and go anywhere else on Pearl St (there are TONS of better options).

Dined here August 2009, I'm reminiscing. 3.5 stars actually. Fabulous place on Pearl Street Market to grab a beer and a great burger. This is a super good family spot and the tunes really enjoyable. It's a locals place, so go and enjoy you silly tourists but don't be in a hurry, okay? It's just so rude. Chill ......

They have an amazing beer selection with unlimited samples. The staff was very knowledgeable. Everyone from the bartender to the waiter to the manager was so friendly! I ordered a beer and the waiter brought me a sample of a similar one he thought I would like, so great! I made my own grilled cheese, had a salad, and a side of fries. All were delicious & fairly inexpensive! I would seriously move to Boulder just to go here regularly! I don't know if I had a few too many beers or what, but I left here so happy. PS. Cash only

Legendary local Boulder hangout. Amazing beers! Generous portions and low prices for food, sort of high for beer and wine, only accept cash or check. We go 1-3 times a week. Fabulous waitstaff, so helpful and friendly, our favorite restaurant by far.

S B.

I love this place. Even when it is busy, the servers will provide you with a beer while you wait. Great hippie ambiance. I always order the Annapurna Amber, and then it's on to the delicious menu. Whether it's an avocado grilled cheese sandwich, or Tim's blackened chicken quesadilla, the champagne vinaigrette steak salad, or just a regular cheeseburger- the food is excellent. The service is great, the beer is great, and the food is great. My only suggestion is to call ahead on busy days to get your name on the list for a table, or you may be waiting quite a while. Thank you mountain sun!

Margaret R.

The beer at this place is so good! I loved the Jah Mon Ginger Beer. They aren't shy with the ginger, and it was very refreshing to experience such an unusual flavor. I also had the opportunity to try the Date Night Burger. It had dates, goat cheese, and bacon. That flavor combination is completely unexpected and completely delicious! There is definitely a reason this place is busy all the time.

The atmosphere is very cordial here. Don't be confused at the entrance. Just bee-line it to the back for an overview of their great beers with the uber friendly staff. I loved the biscuity English style IPA. Bring cash as they do not take credit cards, though as reflection of their good karma ways, you could just mail in what you owe later. The food isn't bad either.

D. W.

Wow...not sure where to even begin. I have lived in Boulder for 10+ years and go here at least once a week sometimes more. Don't miss Sunday night here when there is live music. I love how they have been experimenting and implementing more Belgian beer varieties. The staff is really helpful and cool and would be happy to give you tastings of all the beers to get you acquainted. Some don't miss beers are the java porter, vagabond IPA, Belgo-Java American-Belgo Coffee Porter, Fruitcake, Addiction Coffee Stout, and the famous Hop Vivant. Also, make sure to stop by in February because it is Stout month and during this month there are numerous stouts that are only available then including the Coconut Cream stout & Girl Scout Cookie Stout. Try all of them! Food wise, order the nachos because they are amazing and HUGE. I would also suggest the pollo asado burrito. I get the red and green chile because I love them both. The buffalo chicken sandwich is also tasty and so is the vegetarian black bean chili with tortilla chips. The Mountain Sun also has rotating daily specials which are usually pretty good and feature a daily wrap, soup, sandwich and salad. The date night burger with dates and goat cheese is a new menu addition that is delicious! Now get here and order a beer already! #BoulderOG #BoulderStaple #BoulderLocalRegular

My boyfriend and I visited Boulder for the first time in mid-April. Mountain Sun was recommended to us by a friend of mine who lives in the area. I am so glad we took his advice and dropped by! We dropped in around 7pm on a Sunday evening, so the place was busy gearing up for Music Night. We had a thirty minute wait, but if we'd sat the common table we could have been seated much faster. The idea of communal eating is a little foreign to us, though, so we opted for a private table. We had all the free samples of beer that we wanted AND free french fries while we waited! Our actual meal was delicious as well. I can't remember what we ordered since it's been two months since our trip, but I remember leaving incredibly satisfied and excited about my next visit. I will definitely be back the next time I am in Boulder.

Samantha M.

Yum! I'm new to Boulder and stopped here for lunch the other day. I ended up choosing what HE suggested (Ciel Lumineaux) over my own picks. I had the Boom Boom sandwich, which is a marinated, cheesy portabella sandwich on focaccia bread with fresh mesclun mix. It was *really* good. I'll be back to try more beers!

Our first stop in Boulder and one of our favorites. Some really great beer and some of the most knowledgable wait staff I've encountered. Really like their philosophy towards the business as well as the food and beer quality. I'm a fan, and if we lived close by I'd be a regular!

A very nice little pub serving very well made beers. The java porter is excellent, and definitely worth a stop in. The food is ok - we got a salad and soup, which was probably a mistake in a burger and sandwich joint. The guacamole serving size is pathetic - about 3 bits and your done. But the nachos were great, and a very good size.

Really good beer and great burger. The junk burger was excellent. I'm on a hunt for the best burger in NYC and if this place was in NYC, it would be I'm top five. It was a bit noisy and a bit of a wait for a table but that didn't bother me so much because the staff were friendly And the beer and burger were so good.

We went for dinner at around 9pm on a Wednesday night, and had a 20-minute wait, which ended up being less. There was some good and bad - here's the breakdown: Food: 2 stars We were pretty disappointed in our meals after hearing great things about this place. We both got sandwiches that were sub-par, and the fries were lukewarm and bland. I didn't even finish them, which is saying a lot. Apparently they are known for their burgers, which may have changed my rating had that been what we ordered. Service: 3 stars After being pleasantly surprised that the wait wasn't as long as anticipated, our server got the job done. Pretty standard. Tap beer selection: 4 stars My husband couldn't stop eyeing up the tapper wall. Atmosphere: 2 stars Liked the hippy causal vibe, but the flow of the place is a little awkward with a crammed waiting space at the bar in the back of the restaurant. And it was loud... very loud. So loud that it was difficult to hear my own voice at times. Can't imagine what it is like on the weekend. Overall, go for the beer, not the food.

Mountain Sun taught me to love beer after I turned 21. I used to drink anything but I saw the light at Mountain Sun. Now 4 years later, Mountain Sun is still my go to place for amazing beer and really good food. I always get the Tempeh Ruben which is amazing and can be made vegan by leaving off the cheese. The 1000 Island is vegan! The french fries are also some of the best I have had. Now to the beer. When I lived in Colorado, Stout Month was my favorite month of the year. Last night I had the Java Porter, the nitro Colorado Kind, and the Smoke Screen Porter. My life was complete. Upon my first sip of Java Porter I almost broke into tears because it was so good. It gets really busy here. You need to be aggressive to push your way up to the bar to get on the wait list. In the past I have walked in and just turned around and gone to Southern Sun since it was too crowded. The staff are awesome and knowledgeable. The art on the walls is amazing and makes this a beautiful space. The only thing I wish they had that they do not is Tabasco. They have Cholula but usually it does not do it for me. Otherwise, this is the perfect brew pub that I compair everything to.

Great place. Beers are tasty and there are regular vegan options available. This location seemed a little less organized than Vine St. in Denver but it is also quite a bit smaller (and smaller places can just seem hectic when busy). A bit of a wait mid-afternoon on a Saturday so wear comfy shoes and order a beer while you wait for your table. Tempeh Reuben made vegan=D-lish!! CASH only. :)

I like the Mountain Sun for the great beer they brew. My favorite beer is Annapurma Amber, with a cheeseburger and fries. The beers definitely sneak up on you, so be aware and pace yourself or you will be taking a cab. And FYI, BRING CASH!!! Here's your warning, they don't except plastic. They DO have an ATM though. My only peeve about this place is how LOUD this place is. I can only imagine what this place sounds like with a live band going.

This review is for the bar only, because we grabbed dinner elsewhere before we headed here. The place was packed so I consider that a good sign. Beers were terrific and the employees were super helpful. The bartenders knew their stuff. We got good descriptions of their beers and tastes to help us decide what to get. They were having Stout Month so we tried a few -- yum!

Rachael K.

Came back today to give it another shot and try more beer. We got a sampler of the beer (last time was pitchers) and tried a bunch of house beers (2 ipas, the mocha porter, a pale ale, a berry ale, and Colorado something). I enjoyed the beer more than last time when we only tried two, the beers are true to their names and don't try to be something that they aren't. I'm bumping them up to four stars because the entrees were fantastic and the beer was good, there just weren't any standouts that rivaled my favorites. Heads up: Get here on Saturday around 1 and you are Golden but come after 1:30 and you are likely to end up with a hefty wait.

Such an awesome introduction to Colorado. The vegan options were delicious. The beer was also sooooo good. And this from a beer non-enthusiast. I would definitely visit this place often if I lived here, and I'll certainly be back upon any subsequent visits.

Every time we have lunch in Boulder, this is our favorite restaurant. Their black bean burger, smothered in onions and mushrooms is as good as you'e good to get considering it's not beef. Also, best fries you can imagine, and the nicest wait staff.

Mountain Sun does a quality job all the way around. We stopped in on a busy Memorial Day weekend and they got our party of 5 seated within 15 minutes. The entire staff is on the whole quite pleasant and we thought our hostess and server were definitely above average. The Belgian Trippel, Jah Mon ginger beer, and blackberry wheat were quite tasty an spot on style wise, while the Rye IPA and some of the stouts were good but not great. I'd recommend trying the Date Night burger, which has bacon, goat cheese, and a date purÃ©e and is fantastic. Probably the most unique item in the menu, and with a better bun would have qualified as one of the best I've ever had. Pricing is very good, and it makes a great starting point for a Pearl Street cruise.

At this point I've been to both Mountain Sun and Souther Sun. Both have awesome food and beer for a fair price. I love the Stouts and Porters on tap and services has always been stellar.

Build your own grilled cheese. Great basil blue cheeseburger. Best food and beer I had while in Boulder.

Adam J.

I'll admit they have good beer and comfort food here, but I don't think it's worth it to deal with the crowd, noise, and cash-only policy. If you really having a craving for their beer head to Southern Sun, twice as big with half the crowd.

Harry S.

They burger patties have become thinner and less flavorful. The 20something male clientele only knows two words and they start with F and S. There is no accountability for customer service because all servers wait all tables and there is no proper manager in sight. The beer is still pretty good, but I'm no longer sure sure that it's worth putting up with the rest of the 'experience'.

Jon S.

I absolutely love this place. I don't make it out to RMNP as much as I'd like anymore, but when I do...Mountain Sun is a place I am sure to visit on my way from DEN to Estes Park. During my last trip, we stopped in and sampled a few beers (which were all enjoyable) and had a pint or two. We left with a growler of Colorado Kind and FYIPA. Note: the "growlers" are large Ball Mason jars and leave a bit to be desired for any trips greater than around the corner. I enjoy the location, the relaxed atmosphere and the friendly people. Cheers!

I LOVE MOUNTAIN SUN! I came here again in November when my sister came out from New York for Thanksgiving. We went to Mountain Sun and there was a huge wait, but stuck it out. The girl seating us kept updating, apologizing for the delay, and letting us in on her strategy for getting us seated for as soon as possible. We celebrated my sister's birthday and the staff totally made her feel loved! We got several free items, and one of the servers had the whole restaurant yell "Happy Birthday Kate, you sure are great!" It was so cute. My sister was so surprised/happy that she cried :) Perfect place to show a New Yorker the Boulder cheer. If you don't mind a little crowd sometime, Mountain Sun is a great spot downtown. If you want the same vibe but fewer people, hit up Southern Sun! Its there sister restaurant in South Boulder and is awesome as well.

So as I mentioned before in previous reviews I have been on an extensive tour of Colorado breweries this summer. Mainly along the Front Range. Mountain Sun caught my eye when I was reading the best of Boulder issue from Boulder Weekly. This instantly beckoned to me to go try it. I am very glad that I did! I had a wonderful Blackberry beer which was to die for! I could really taste the berry in it unlike other breweries that I have been to that claim that you should be able to taste a berry flavor in the beer but it fails to do so. Steven got a ginger beer which was also awesome! We went ahead and proceeded to order our meal. We both decided to get some grilled cheese sandwiches which turned out to be an awesome choice! You can pick from various ingredients which are all so fresh the sandwich will knock your socks off! We decided to get salads instead of chips with our meal which I don't know if that was a slick up sale on the waitress's part or a bonifide substitute. On the bill we were charged extra for the salads and also overcharged because the guy that made our bill misread what the waitress wrote. He corrected the bill instantly but the salads we thought were a bonifide charge even though it made the meal more expensive than what we thought it should have been. Despite the error with the bill our meal at Mountain Sun(which did not result in any deductions on stars... surprise!) was awesome and of course you have got to try their beers if you don't eat anything. They have a sister location named Southern Sun, also in Boulder which makes the awesome food and drink even more accessible!

Great selection of local brewed beer. The service was great and food really good. B/c there was a wait when we got there, we went to the bar, where the bartender let us sample the beer before we ordered; he was real nice. Lots of table for four, so be cautious with large groups when it's crowded.

Scot P.

I've been a fan of Mountain Sun for more than 10 years. It's a favorite for some of the best burgers in Boulder and with grass fed local beef it's even better. My favorite is the junk burger but look to the specials for a unique burger experience. Add on top of that it's also a brew pub. My favorite, the Illusion Dweller IPA. Hard to believe they can brew beer in this small space. The Pearl street location is small but very friendly. They don't accept credit cards, which is the only reason I don't give them 5 stars, so remember to bring cash. The cash machine in the back charges you an extra $1 on top of what ever your bank will charge.

Sara P.

This place is a rollickin' good time. I liked several things about Mountain Sun. First, they make a ton of beers, and they are good. I had both the english-style and american-style IPAs. They were both unique and very tasty. I had the blue cheese basil burger, and it was cooked perfectly, the sauce was amazing, and they somehow had tasty tomatoes at the end of December. I love their service model here, where it seems that everyone wants to make sure that the customers are taken care of, and the servers and laid back and friendly. I'm so glad I ate and drank here!

Back to one star again. There was an amazing sounding beer on the menu, but they were out of it and had been for a while. If you are out of it TAKE IT OFF THE MENU.

I loved Mountain Sun Pub & Brewery so much I went there twice during my visit. Nice casual environment. I loved the colorful murals painted all over the walls. Mountain Sun has an excellent selection of beers, especially a good variety of stouts. For a change, I also tried their blackberry wheat beer, a lighter beer that was also very good, although I maintain my preference for stouts and other dark beers. This place offers some great pub grub. I ordered the mushroom onion Swiss burger, and it was excellent. If you are in Boulder and looking for a place that serves great beer and food, while dishing out some local color, then you must give Mountain Sun Pub & Brewery a try.

A lovely spot on Pearl (less manicured and trendy than its neighbors, which is a good thing!), with a fresh appealing menu and an extensive, enticing beer list. I've been listening to my little brother and his wife sing Mountain Sun's praises for a while now, and was happy to see why on my Boulder visit. Since I'm an IPA girl, I was happy to see three of their own (not all on tap at once) right up front on the list. The F.Y.I.P.A. was bright with a hint of citrus depth, and well-balanced enough that even folks who aren't hopheads should be able to appreciate this great beer. (Personally, I haven't yet met an IPA that was too hoppy to love, although I've tasted plenty that weren't hoppy enough to be worth it!) As other reviewers note, they always have a tap or two on nitro, which is a great thing to see at a brewery and I hope to run across more frequently. Another plus to Mountain Sun: you can order tasters, and for a larger drink, you can get your beer in an 8, 16, or 24 ounce pour. I'm always glad when I can have a smaller drink. Then I can have more of them! The food was good as well; chips were upscale root-vegetable/taro style, a nice touch. Very friendly service, and a nice laid-back, beer-loving yet family-friendly atmosphere (there's a kid's menu with good stuff). If there was a spot like this in Seattle, I'd be there all the time. So maybe it's good that there isn't....

Suds, buds, and great service. Everything here was most definately laid back but truly on point. Everything from timing of food, refills and questions being asked were excellent. The Asst Mngr whose name I didn't get to write down before jetting out even stopped by our table and made sure that our experience was wonderful. We had an array of servers but the trainee and trainer who initally served us were also wonderful and friendly! I look forward to the specials on my return! Thanks again!

Carlie D.

My friend sent me a text that said go to mountain sun brewery and get a colorado be kind ale. that is exactly what I did. repeatedly. i think the be kind ale on nitro was my favorite of the two versions. the food was good too. far better than a lot of bar food that is out there these days. colorado be kind on nitro. do it.

OMG 5 STARS!!! Rarely does a place get 5 stars but this one did. We visited on the Friday night before the first CU football game so we expected to wait. We went to the bar in the meantime and all the bartenders were very friendly, giving us tastes of their brews. We shared the quesadillas and the nachos. They were better than most Mexican places we have been. The nachos were gigantic and piled high with ingredients. We cleaned the plate. We will go back when we are in town again.

Steph W.

Food was EXCELLENT! And the beer was wonderful as well! The service was great, and the atmosphere was really nice! However-- we were a little overwhelmed by the service-- they are very chatty people! My husband and I are pretty introverted, so it was slightly uncomfortable. However-- some of you might not mind that at all. Give this place a try, their food and beer is excellent.
(5)
Alex B.

I haven't tried the food here, but the beer is excellent and the bartenders are friendly and helpful. I told them I liked IPAs and hoppy beer in general, and was immediately given 4 samples, no questions asked. I decided on the XXX Pale Ale, and was not disappointed. As much as I like the place, there are a couple gotchas you should know about: (1) They *only take cash*, so be sure to have enough on hand. (2) This place is really popular, so it can get loud, and finding a table is a challenge.

I first got to know Mountain Sun a decade ago when introduced by a very good friend (my thanks, Rich G.). It was a great experience, but I had given most of the credit to Rich. Opportunity knocked and I was able to return for lunch on a mental health day I had built into a business trip. Not just good company a decade ago - this visit was great: wonderful service, great recommendations, a savory spicy sandwich, and a sampling of some great beer. Well worth the visit for lunch on Pearl Street.

Went on vacation this weekend up to Denver and had the opportunity to visit Boulder. I love this college town. I wish I would have been up here as an undergrad with this many in shape and hot students. Seeing as I had my girlfriend with me, it was not polite to look hahaha. I've been to Boulder before and had lunch at BJ's. I remember that I wasn't to impressed with their beer or the food and was looking for another good brew pub. I did some yelping (thanks guys!) and found this jem just off the mall and out of the craziness. We stepped in and while it was busy, the staff immediately took our names and invited us to have a drink at the bar while we waited. I looked through the list of brews and decided on the Raspberry Wheat. I've been in the mood for wheat's and golden ale's etc for the last month or so because of the warm weather. It was delicious with just a hint of Raspberry. I would have actually enjoyed more. My girlfriend and I ordered a pitcher and we got to see all the action behind the bar and in the kitchen. A table opened up and we sat down starving. I usually don't ding reviews on the service, but we waited for another 10-15mins before anyone came by to check on us. It wasn't that big of a deal because we had beer, but we were both ready to destroy some lunch. Our server was cool and helped out with recommendations and we got another round of the ginger beer and golden ale. I got the American fields salad which was a bit different from my usual fare and my gf got a cup of chili and an avocado sandwich. The food arrived and my salad was a bit of a disappointment. I've been on a salad kick lately as well and this was just a bunch of shit tossed together with greens called a salad. I'm being picky I know, but there was waaaaaaaaay to much salad, not enough of the fun stuff (strawberries, blue berries, almonds, red onions) and the dressing was on the side. Some people like that, but I hate it. Especially with greens overflowing my plate. It's an exercise in dexterity not to push anything off your plate while trying to mix it together. This salad had a lot of promise but the execution was lacking. I should have gone with the spicy pollo burrito. My gf's sandwich looked good and I stole a bit of her chili. OMG it was delicious. I then had to order a cup of chili too! hahaha it was the best part of my lunch. Overall, I really liked this place. It was really chill, everyone that I talked with was mad cool and the beer was great. I just had a sub par salad and it took us a little while to get some food. I would come here again and would recommend it over most of the restaurants on Pearl Street.

Angela L.

Only reason I'm not giving this 5 stars is because we didn't eat here so I'm not sure how the food is. The beer, however, is delicious. We stumbled upon this place this past weekend during our day trip to Boulder. Worth checking out. I'd recommend their beer flights - 6 samples of any beer on tap. Our waitress Natalie was friendly and knowledgeable about the beer.

We stopped in this brew pub recently during a short stint to Boulder, in which we managed to fit in stops at six different breweries. Mountain Sun was fantastic- and easily the busiest brew pub we visited. The staff were laid back and friendly, and they treated us more like we were visitors in their own home rather than customers equal to a sales percentage and tip. We were offered beers to sip while we waited for our table, and once seated, had a hard time choosing from all the delicious options on their menu- beer and food both. The service throughout our meal was as attentive as you could want, but never obtrusive or overly eager. This place was great- bottom to top.

We went to the Mountain Sun for lunch yesterday... and as always, the food was impressive and the beer plentiful. I settled for raspberry iced tea yesterday while pseudo hubby enjoyed a Kind beer and a Crippler (Kind & the IPA mixed) ... very potent. I like that you can get beers in 8 oz sizes also... this makes it easier for people like me to try multiple beers without getting full from one single pint glass. I had the special sandwich yesterday - the Boom Boom - grilled & marinated portabello mushrooms, roasted red peppers, provolone, pesto mayo, and a little lettuce sandwiched between lightly toasted ciabatta bread. I liked that the bread was light and not too dense and filling for the lightness of the sandwich. The grilled peppers and pesto mayo were really fantastic with the mushrooms. The plate was piled with freshly made fries and a crispy pickle spear. The man ordered the reuben - a tempeh reuben - it was pretty good too, although I don't know if I'd order it again. I like tempeh, but when it comes to a reuben, sometimes you need the real meat. This was a very good alternative though, complete with saurkraut and tasty rye bread. We showed up at about 1:30 on Sunday, which was a good time... the lunch crowd was just winding down and we waited at the bar until a table was ready. There was a wide mix of people and a lot of kids enjoying time with their families while playing some of the complimentary board games. You just can't beat the Mountain Sun.

Matt T.

I've been a fan of Mountain Sun for many years...the service is top notch with a well informed and friendly staff....the food and sandwiches are delicious. Each beer is a strong representation of it's style....I really enjoy the times that the brewers go above and beyond. No credit cards are accepted but they have an ATM in the back you can draw money from...if bored you can always grab one of the board games available and see if you can rustle up a game with a nearby table. Overall...a great job and a place I always feel welcome.

Todd H.

Cash only! I had the tempeh Reuben (and while not as satisfying as a real reuben, it was very tasty). Mom had the 1/2 sandwich & soup and she was very happy with that. Spouse had the Quinoa salad special and enjoyed it too. Beer was very tasty. Service was good. It was a pleasant surprise because I was expecting a place on the Pearl street mall, but this is a block or two off the mall.

Brody G.

Despite the fact that I almost always read and refer to reviews, I rarely, if ever, write them. I expect that someone else will take their precious time to comment on the average food, average service, and average experience... Mountain Sun Pub & Brewery was ANYTHING BUT AVERAGE! Our experience began about 4 blocks away where we caught the first scent of boiling malts and steeping hops. By the time we walked the half mile to the restaurant my senses were in full blown, blissful overload. Walking through the door of a brewery I expected the assault of TV's, loud drinking and raucous laughter, but was pleasantly surprised to find a busy, but peacefully quaint "cafe" style restaurant. We were immediately greeted by a smiling, and sincerely warm and friendly member of the staff, who apologized for the short wait. He eased the pain of that sting by immediately taking us back to the bar where we were offered what amounted to roughly a 6 pack of free tasters of their home brewed beers. Being a home brewer, I appreciate the heart and soul that goes into a finely crafted beer but this was a truly an amazing experience. Not only were the beers, ALL of them, amazing, there were no less than 4 of the staff bringing us samples as we waited. It was like they were sharing their favorites with us and wanted to make sure we had the opportunity to try them all before we had to settle on just one. As if were were not already won over, their eagerness and warmth to share with us was endearing, and showed what an amazing pride and joy they all had in their place. Oh yeah...there was food there too!!! Of course, when looking for a brewery you want a burger to go with it...but you never expect that you can have your brew AND a healthy meal!? The menu was beautifully pub-like, with a healthy and wholesome slant...burgers with fresh ingredients and whole grains, salads and sandwiches. My wife and I both had burgers and salads to go with our awesome beers; I had their JalapeÃ±o burger and the wife had their Cheeseburger with Pepperjack. In a society burdened with the notion of quantity over quality the size of the meal was almost laughably meager, but since I was paying a meager price for the meal I decided it wasn't worth complaining about. Little did I know that truly amazing food and quality doesn't require obscenely large portions, and we were amazed to find that halfway through the meal we were already blissfully full. It was as if some intangible, ethereal ingredient, passion perhaps, had supplemented the smaller portions to insure we walked away complete. Of course we finished the burgers anyway, but due to the quality of the food we walked away conscience intact. ALL of the above qualities, combined with the wonderfully pleasant philosophy of the pub, one of employee ownership and integrity, made for something better than a great dining experience...it made for a taste of community and comraderie where we felt like we got to share in the success of the entire brewery! This is one of those places you not only visit again, you hope to call home. I cannot wait until we get to go back to "our" pub!!!

Idan S.

My ex-girlfriend's friends used to love this place, so we always wound up going there for dinner. I've never had any food there I particularly enjoyed (nothing horrible though). That being said, I don't think any of their beers are all that good either.

I used to come here when this was the only non-smoking place in Boulder many many moons ago. Way before the parking garage was there which is now across the street. I also saw Yonder Mountain here one night after the garage was built, and after the small show, we followed the band to the top of the parking garage.We danced with the band playing acoustic on top of the garage until the police came and asked us to leave the garage peacefully. Those were the days I tell ya... Decent food, awesome beers-my favorite is the Java Porter. Inconsistent service. Sometimes excellent, sometimes completely LAME. have worn the shirt all over the globe-got most comments in New Zealand-people wanted to buy the shirt off my back! I can't imagine visiting either of the other locations, as there is only the original for me!!

Jackie O.

This is a cute nice little brew/eatery. Came here out of a chance just walking by. The food was above decent bar food and the beer was good too. everyone found something they liked. Nachos are HUGE, split that between 4 and a couple other things too. I wouldn't go here for dinner but a lunch or snack would be perfect.

Hailey B.

I am giving this 4 stars instead of 5 (see my review of Southern Sun) ONLY because of the location. Mountain Sun is a bit too claustrophobic and dark (and no outside seating) for my taste. Menu is the same as S.Sun and waiters are just as awesome. Parking and noise level on the other hand, not as awesome...

John S.

After our rigorous hike on the Chautauqua trail (one that was cut short due to the ailment in my fathers knee) we were all famished and needed to replenish our bodies. One of our party members suggested we stop by pearl street and search for a restaurant. After a long and dreary search we stumbled upon a restaurant called "Mountain Sun." Indifferent about our groups decision I reluctantly joined them..... And I must say I was thoroughly pleased. I ordered a pollo asado burrito and after the first bite the spiciness of the burrito and the aroma of marijuana coming from the hippies of boulder mixed perfectly. I have to say that I felt one with the "Mountain Sun."

Who said you can't pretend to be in college again... woah this place made me feel a little old. I have been out of school 4.5 years now and visited Boulder on a work trip. Grabbed dinner here after arriving from DIA pretty late one night. Great spot for a good burger. Thinking I would just grab a beer and a burger at the bar... was a little surprised when I saw that there was no bar area. I sat down and chatted with some nice college kids playing scrabble! Regardless of feeling a bit old and grabbing a burger solo on a work trip... the food was fantastic! Fresh and organic! Very Boulderesk! Recommend this spot for lunch or dinner! Cheap and excellent! Plus a great location on Pearl Street!

Mark M.

Great beer made on premise, excellent kitchen, fantastic staff, fun patrons. Did I miss something? I got a tip from Boulder Music to try the place, and then we happened to walk by it while hungry...bingo! Glad we did. Wait was long, but walking around the block is fun so we passed the time quickly. FYIPA was fantastic. The staff is so friendly, warm and accomidating. Everyone...not just one of them. wow. Kitchen was very slow (my only complaint), but food was great. Fantastic burger and excellent fresh cut fries. Yum yum! Oh, and the FYIPA.... It's kind of funny how everyone waiting around is crowded up by the bar. It's cramped and very loud, but I also found it strangly appealing.

Shea S.

As a note, this review is just for the beer. Stopped in to give the brews a try, and was a bit surprised at how small the joint is. You can enjoy a brew, but you have to stand at a bar that serves as the staging area for the waiters. They were nice enough to give us a table after it settled down, and the service was great, bringing us water even though we weren't ordering anything else. If you want to just get a drink, this may not be the place. The food looked good though, and I look forward to going there when hungry. The beer was tasty, with their doppelbock with their blonde being very good. I'll have to try some of the darker stuff next time (when it's cooler out).

Pretty tasty! Lots of interesting clientele to watch - beer was good, not the best i've tasted but not bad. Had the veggie burger - pretty standard, nothing to write home about. Tried some veggie chili - very tasty. Def get this. My friend had the grilled cheese with bacon and pesto - good but a little greasy. 4 stars - cash only.

This place was amazing! The staff was as nice as any place I've ever been. There was a bit of a wait when there on a Friday night, but we were offered free beer when our time passed. We were seated 5 minutes later. The beer was excellent! Absolutely the best brewery we visited in CO! There really was a team mentality in the restaurant, every server who walked by offered to top off our water, asked us if we needed anything,etc. The food was amazing! The burger I had was out of this world. I can't wait to go again!

I think most would flock to this place for the beer. I'm not a beer guy but can attest that the burgers are well above average. They were gracious to bring out some sample beers anyway and it was enjoyable to try them. The fries are a claim to fame and also very tasty. Quick warning: ranch dressing is an extra .50 cents but when you factor in the service it is no big deal. Honestly, the service at this place was just awesome. Each server was overly attentive and very kind. Would definitely go back and I encourage you to as well!

We didn't know what to expect since we aren't from Colorado but we were pleasantly surprised! I didn't have any troubles getting a vegan Ruben (which happens to be my most favorite thing in the world). The beer was great, the service was awesome but the sandwich only left one thing to be desired...I'm not the biggest fan of tempeh so I would have liked to had a seitan-based sandwich. Otherwise it was complete awesome sauce! I would definitely go back and would bring all my friends!

Exploring Pearl street and its many treasures earlier in August brought us into Mountain Sun for a drink and a bite to eat. Service was great and the food was tasty. Everyone was friendly and helpful. We got a sandwich and a quesadilla. Hop in for a good meal and a drink and explore the beautiful artwork.

Well, I was in Boulder for only a week and came here three times. My fiance came here four times! That says a lot. We absolutely loved it here. They are very vegetarian and vegan friendly, with everything very clearly marked. The free beer samples are great for someone like me who is picky and has trouble making decisions. Check out dollar taco night, their kind ale, and the delicious black bean burger. We even saw a great band here (The Blackberry Bushes) and bought two CDs. Our service, food, and atmosphere was really perfect on every visit. This is a Boulder must-visit!

It was SO LOUD when we came here on a Sunday at 5pm. I thought that by going to dinner so early we would have a quieter experience, but this it not that kind of place! My partner and I shared the nachos (woah, that's a lot of nachos) and a Date Night burger. I loved how stacked up the nachos were, but most of the chips were soggy and sad by the time we got down to them under the heaps of black beans and salsa. I liked the burger, as I've never had a burger with dates on it before, but wasn't too impressed by the GF toast used as a "bun". Probably would have been better on its own. The fries were really delicious. Free beer (and cider) samples at the bar. They had a cider on tap as well as a GF beer in the bottle. Servers were extremely friendly. The crowd was pretty young, but that's understandable since school is about to be back in session. We saw a good amount of little kids there too so I assume they are at least somewhat child-friendly.

My posse and I had a great time here! The friendly staff bring samples on samples of beer! We ordered about 10 samples and liked almost everything we tried! The standout beers: the Hummingbird Honey Ale and the Desert Cities Cream Ale. Despite ten samples the whole table gravitated to these two! The food was also reasonably priced, so we split a huge plate of delicious nachos. I'll be back to hang out here.

I loved the welcoming atmosphere here. Once we put our names on the wait list we were given the option to head to the bar area and sample any beers we wanted before making our selection. That was a great first start and a nice way to wait, along with some fresh cut fries. Everyone working behind the counter made sure we were helped and taken care of. When it was time to eat my husband and I split their bison burger which was superb. Because we had fries with our beer earlier we got a side salad which was a nice way to get our greens in. There's a variety of people that come to this place, families, couples, friends hanging out. A nice atmosphere for all to enjoy.

Darrelle G.

Alex and Anna are the BEST! Wow- what great service. Alex brought us beer tasters during the wait for our table- Anna was a kind and accommodating waitress. My favorite beer is the raspberry wheat! My boyfriend lives the FYI pa. I love boulder and our meals were great. We will be back.

Great place to have some pub food. The place is laid-back, and not crowded at least on a tuesday afternoon. I had their special barbacoa sandwich.

Mike S.

Mountain Sun continues to be my favorite brew pub in Boulder, maybe anywhere! Tonight - usual great house beers, awesome spicy pollo asada burrito and Tim's blackened chicken quesadilla (regular menu items), great special Tuscan Summer Chicken (marinated grilled chicken with grilled potatoes, artichoke hearts and endive). Tonight's creme de la creme - chocolate cake with a salted bourbon caramel frosting made with their Hooligan oatmeal porter. Are you kidding me?! Awesome. Of course, the usual great wait staff and fast service. All for $60 with tip. Last trip to Boulder and Mountain Sun, my son was thinking about being a Buff. Starting this fall, he will be a Buff. Looking forward to many great beers and meals at Mountain Sun!

Jackie S.

My fellow yelpers didn't let me down on this one. The list for a table is at the bar which is crowded and bustling. Our name was taken and we were handed a drink/beer menu. I got a Colorado Kind Ale, delish. We were seated in 10 min and given the rundown on how the service works. (There's a team). I got a small salad to start fresh, diverse and good balsamic vinaigrette. My son had a burger which was good and I had the chicken burrito which I was warned was huge. It was really good and service was impeccably attentive. The only slight critique Id have was it felt a little rushed. Other than that it's a cool vibe w wholesome fresh fare.

Amber A.

Two words; chill and beer. This place is super laid back and has great beer. Colorado Kind Ale is the beer we chose and it is good- a lot like flat tire. Also had chips and salsa which was good. We got a couple seats at the outdoor area which was fun people watching!

We stopped in here because I'd read good reviews of it last time we were in town and we were SUPER hungry. Its a pub menu so I didn't expect a ton, but they actually had some nice vegeterian dishes and salads. I got the special; an asian salad with tofu and my husband got the cheesesteak. The salad. WOW. Super fresh spinach, arugula, basil, edamame, carrot and fresh red pepper. I mean, who knew you could go to a pub and get an amazing veggie salad? the tofu was perfectly marinated and all the veggies were fantastic and crunchy...the carrots were even fresh shaved. The dressing was off the hook good. Hubby loved his cheesesteak. We also got a side of fries that were clearly house cut and cooked, and were delicious. Hubby loved their Kirsch ale. I got the pink lady which was pretty weakly made (first night at elevation and I should *feel* my drink and didn't at all) but hard to complain for the price as it was our cheapest meal in Boulder. Worth a visit for sure! We'll be back.

Stout Month was amazing, much to the chagrin of my wallet, and those cheese fries. Damn. I hate that I love you, Mountain Sun.

Birch Moon M.

Great place! Excellent selection of beer. Excellent selection of food. The wait staff was helpful and friendly. The decor is fun. The Java Porter was awesome! The nachos were more than enough for a meal or two. A little loud, but not too bad. Easy parking on a weekday. I really liked the tempeh rueben. Good selection for vegans and vegetarians. Service for us was fast and attentive.

Melissa T.

So awesome! Amazingly nice service complimented with delicious, filling food. I got the bison burger (SOOO good) with fries and a cider. Wait was pretty long (30 min on a Friday night for four) but we stood by the bar and they came to get us when our table was ready. This seems like THE spot to go to if you're just visiting Boulder

Great beer, tasted like one of my homebrew recipes. Food was awesome, great meat on my burger, everything tasted fresh. The pesto grilled cheese... Just get it. Dont argue, just do it. I usually like syeak fries but these shoestring fries had great flavor. Reallly great flavor. Mmmmmmm fries. Happy servers too, all really helpful. Go here, eat, drink beer, be happy. Cheers!

This place has great vegetarian items (both light and crazy heavy like the nachos). Their beers are amazing, and I believe they are owned by the same people that own Vine Street in Denver. My only gripe is that they dont accept cash.

I was hanging out in Boulder today with five other adults and my little one. It was time to eat and we were looking for something to please us all; a couple vegetarians, meatarians, beer lovers and a child. This place seemed to fit the bill. We were lucky enough to get a table immediately, by the end of our meal the place was packed and on a wait. I just mived t o Colorado and have been eating EVERYWHERE, so I felt like I should take it easy with the half sandwich/soup combo. I got the Boom Boom (a veggie sandwich) and took the servers recommendation, the veggie chilli. Sandwich was delicious, soup was awesome, and it was was plenty of food. I was struggling in deciding on which beer to get, they have a fantastic lineup. She let me try two samples, a tripel and a barleywine. They were both QUALITY! Then I remembered it was noon on a Tuesday and I completely 360'd and went with a kolsh, great decision :-) My comrades choose burgers, a steak sandwich, a veggie burger, and I got my kid some fresh veggies. The dudes all gooed over how amazing the burgers were, I believe that I heard "best ever." Super great service, beautiful decor, and fabulous food. I see myself coming here often!!!!

I went to Southern Sun first and was surprised how small this place was. Despite that, we had a party of about 10 people and they were nice enough to keep us updated on getting a table and were willing to push three tables together for us even on a Friday afternoon. Good beer, good pub food, and a fun place to hang out! The raspberry wheat beer was my favorite but they just changed it to apricot wheat.

Lucy H.

Solid food - I've never had a bad meal here. The staff seems very friendly and helpful when picking out your entree or drink. Cash only but there is only $1.00 surcharge for their in house machine. I want to go at night but during the day it's family friendly and quick service.

Very good food! All staff were friendly and attentive. Love the karma policy - no cash? Take the bill with you and Mail your payment when you get home! Had cheeseburger. The beef was very good, tomatoes were very fresh. Crowded at lunch but we got there at 11:40 am on Wednesday and easily got a seat.

Tim C.

Good food, good beer, mediocre service. The wait for a table for one was half an hour at 9 PM on a Sunday night, even though there were empty tables when I walked in with no one making a move to sit there. It's cash-only. The ginger wheat beer is good. The server messed up my order, which is understandable on its own, but then when another server brought my fries (without cheese) and I said I ordered cheese fries, that person never brought back my cheese fries. My original server came back to ask me if everything was OK after 20 minutes or so and seemed surprised when i said I hadn't gotten my cheese fries. Also, a third person asked if I wanted change when I paid my bill; I said yes, but he never came back with the change, so eventually I got fed up and left. The menu explains that the business is run cooperatively with everyone taking turns doing different jobs, and waitstaff teaming up to help each other's tables during one evening, but based on my experience this just seems to lead to bad, uncoordinated service.

Amber L.

The majority of these reviews were spot on! The junk burger was awesome! My brother got the special wrap, amazing!!! And my boyfriend got the go gooney bird, my option, a little dry.. But the beer was fantastic and service incredible! I would most definitely come back. And bonus if you buy a tshirt on a Tuesday, they'll buy your beer :-)

After a performance at Macky Auditorium, found them via Yelp app as highly rated. Craved a burger but was informed the kitchen was closed on arrival. Server kindly offered nearby burger options when asked but I decided to stay since I was already here and they do have dollar tacos (in chicken or veggie.) Ordered 2 veggie tacos and an 8 oz Big Krane Kolsch. Requested an 8 oz Blackberry Wheat brought out when the kolsch was low. Kolsch was good. In fact, made me wonder what "legal" KÃ¶lsch is like. Tacos arrived a little later. They are soft tacos on flour tortillas and are reminiscent of fish tacos sans fish (with cabbage, I think.) They ended up being chicken, but I didn't care since I'm not vegetarian. While it was the wrong type, they redeemed themselves by being far better than the price would suggest. Blackberry Wheat was served right on cue. It's more... colorful (?) than imagined and sweeter than I'd like. Maybe even a tad medicinal initially, but that impression faded after a few sips thankfully. Not terrible, just not my preference which is to get more of an essence than actual fruitiness. (The Watermelon Kolsch from Golden City Brewery achieved this for me.) In all, I was happy with the service, food, and beer. They've earned a return visit and I look forward to trying a burger... P.S. It probably bears repeating that they are CASH ONLY (or local check - ha.) There's an ATM in back.

My husband and I stopped in at Mountain Sun Pub for an early lunch. We had a nice and helpful server. He had some great suggestions about beers and was happy to get tasters for Mike to sample. After he decided on a beer he really liked, we ordered some food. We weren't super hungry so we got a Quesadilla and the Speakeasy Steak Sammich to split. The Quesadilla was awesome in a way that I didn't know quesadillas could be. It was packed with veggies and not gut-busting in any way. The salsa and guacamole that accompanied it were fresh and flavorful as well. Mike said it the best when he voiced his thoughts aloud later: "I had no idea, when I ordered that quesadilla, I would be as impressed as I am." It was a great price too! The meat in the steak sammich was expertly cooked but maybe just a touch under-salted. I loved the use of arugula and caramelized onions in this sammich. The arugula was bright and peppery and the caramelized onions were just the right amount of sweet. I enjoyed the artwork in this place a lot. There is a great floor-to-ceiling piece of art near the front window that is colorful and creative and their ventilation (near the ceiling) have hops painted on them. Just a quick word about dogs... While we were heading inside, a few people and their dog were asking if they could sit on the patio. One of the staff let them know unfortunately dogs are not allowed on their patio. They are also cash only so come prepared!

YUM - I got food to-go twice from here. The people are very friendly and will quickly asked if you're being helped when they see you. I have had the hummus and cheese sandwich. It was really delicious with the right amount of hummus. The bread was fresh and the vegetables too. It came with a pickle and tortilla chips. Also, I have had the customizable grilled cheese sandwich. I made mine with cheese, bacon, and tomato. This is a must try if you love grilled cheese. This also came with a pickle and tortilla chips. Both came in to-boxes that were easy to recycle. I love that. The food is delicious which is why it encouraged me to sit down at Southern Sun.

Great beers, and their grilled cheese and soup mix is phenomenal. Bring cash though, they don't accept credit card

Dana B.

With a funky atmosphere, you'll feel welcomed as soon as you walk in the door. Don't be turned off if the place is packed and there's a wait, free beer tasting at the bar during your wait time! The free beer samples and crazy wall art kept us occupied during our wait. When we got seated, the menu looked too delicious to let us decide. Our awesome waiter was patient and pointed us in the direction of his favorites, they did not let us down. The nachos were to die for, cheese on every chip! We had the date night burger, quesadillas, the junk burger, and the speak easy steak sandwich. We loved everything about our meal and we will be back for more. To make our meal even sweeter, the prices at this place are phenomenal! Make sure you have cash! Mountain Sun only accepts cash or check, they do have an ATM in the back.

My goal is to visit as many Colorado breweries that I can before our family heads back to Florida. Mountain Sun Pub & Brewery was my 14th brewery since August 21st. Bryan M and I had two of our teens with us. We were headed up to Nederland to enjoy the fall colors. We were looking to grab a bite to eat in Boulder where I could also enjoy some local craft beer. Bryan & I had been to Vine Street Pub & Brewery during our 2012 visit. Mountain Sun & Vine Street is part of the same family. We enjoyed our visit back then, so I knew stopping in Boulder would be good. Mountain Sun has more of a "Boulder" restaurant feel that serves in house beer than a brewpub (similar to Yak & Yeti). We got a booth and while they browsed the food menu I took a look at the beers. I got a flight consisting of: Raspberry Wheat, Illusion Dweller IPA, Annapurna Amber, Rouge de Bruges, Hummingbird and Isadore Java Porter. All the beers were solid. I enjoyed them all with the Porter, Hummingbird and Rogue being my favorites with a 4.5* on Untapped. The Porter has a great coffee smell and taste and the Hummingbird smells wonderful with its orange blossom honey. It's always nice to enjoy great beers with some tasty food. Everyone enjoyed their lunch and the kids got a kick out of their "Karma" policy. They only take cash or check. If you don't have either just mail the payment when you get home. I can see why Mountain Sun is a favorite among the locals and tourists alike; the beer, food and atmosphere are one that is wonderful.

Lexi S.

The service was outstanding! The hostess invited the group I was with to the bar for free beer tastings while we waited for the table. The bartender then offered many suggestions, and almost a dozen beers were probably tasted. After being seated we were welcomed by a very enjoyable waitress who was personable with us the entire time. We joked around with her at the same time she gave us some tasty suggestions. The date burger (substituted chicken for beef) was a pairing I never expected, but will have to recreate at home. And no words could be said about the chicken burrito with red and green chili! I will come back here when I revisit Boulder in the future.

Leanna C.

I am a huge fan of all of the mountain sun establishments! The beer selection is always amazing. I've never ordered a meal here that I didn't like. If you like fruity beers definitely try the blackberry wheat beer, I typically get a growler of it to go because I can't get enough of it. Food, oh boy where to start? I love the salads here, but you can't come here and just order a salad. I usually get a burger and get a side salad with their homemade balsamic dressing (it's actually life changing). I almost always order whatever the special is for the day, usually some sort of burger or burrito that is just a little different from all of the others. Without a doubt try the date night burger and the burrito smothered in green chilli. Everything here is always great BUT you have to have a local check or cash at all of their establishments (southern sun, under the sun, and vine street pub).

Daniel B.

Been hitting up the Mountain Sun for almost 20 years I've lived in Boulder. Even stopped here on my first date with my (now) wife. And I don't even drink beer. I think the Mountain Sun has one of the most underrated burgers in Boulder, the Junk Burger. Love it. Order it every time I come in. Service is often good. No complaints there. For beer lovers, I'm sure they have something for everyone, but if you're an omnivore like me, then give the junk burger a try too.

Rw F.

One of the few places on pearl street with a wait on a Monday night, packed with patrons inside and out. Even having to wait for a table wasn't bad. Free beer tastings at the bar until we were seated. The pesto grilled cheese was good. The fries were good too. The black bean chili didn't have enough spices though. A very friendly place to hang out. Plenty of kids games to play and a very good waitstaff encourages you to linger.

After several recommendations while sampling brews at other breweries around Boulder, we stopped by for a beer flight and some burgers and we weren't disappointed! We had the bison burger and junk burger, and both were delicious! Great atmosphere and great location on the Pearl Street Mall!

Ashlin M.

Great service, amazing food and beers! Bison burger, quesadilla and burrito were all delicious! This place has both great food and great beers. Not the typically bar food. It's an actual restaurant first. Won't disappoint!

Excellent place! Beer samples until you find the "right" one. The most perfect burger: SOB Burger. And good prices. It was a bit loud but clearly a happening place. Would certainly come back!

Rachel D.

Really nice place. We waited up at the bar for a table, they let us try a lot of different beers to make our decision, and we even got free fries while waiting there (and the wait was only 10-15 minutes, not bad). Once we got a table, we were able to choose from a variety of boardgames to play (we chose Battleship, I totally won). The servers all work together as a team, and were very helpful. The food was delicious, so was the beer!

Tony S.

We've been coming here for years, and have always enjoyed it. This visit really stood out... AWESOME beer & total team effort. They were the busiest business on Pearl Street on Friday evening. Yet the GM, Jess, had her team super well organized. They flowed in unison, with probably has 6-7 servers recommending beers and repeatedly bringing us samples. We felt really part of the family. Thanks!

Stopped by for lunch after a nice hike at Chatauqua, and pretty much cancelled out my exercise with burgers and beer. Totally worth it. The restaurant was full but the awesome friendly guys at the bar made us try a bunch of beers while we waited and gave us crispy fries, all fo' free. They seriously filled up the small glasses as free samples. I was pleasantly buzzed by those alone, lol. My favorites were the nitro Pearl Street porter and raspberry wheat. For grub I had the date night burger. I wasn't expecting to be blown away by the burger, but honestly it was one of the most scrumptious burgers I've ever had. And I'm pretty sure it wasn't the beer talking! :) The salty bacon and goat cheese combined with the sweet date puree was a marriage made in heaven. I can't remember what my boyfriend had because I was too enamored and obsessed with my burger. Our server was super friendly and attentive, too. Overall, what a fun place! Don't forget it's cash only! Great beers and service. If you like goat cheese, don't miss the Date Night burger - heavenly.

Taylor W.

Just stopped in to try a beer of theirs and didn't realize they were cash/check only. FYIPA is delish. The wonderful bartender was so kind as to take care of my beer since I was just stopping to try them out. Amazing hospitality and customer service. Will definitely be back here!

Kelli H.

Mountain Sun is one of my go-tos when I have friends in town and want to show them great beer and great food. What really puts Mountain Sun over the top, though, is their impeccable and friendly service. The last two times I've gone, I've gotten several of their seasonal beers - some on nitro which always adds an extra touch. My favorites so far have been some of their sours. To eat, I've gotten the date burger, with goat cheese, date spread, jalepenos, and bacon. It's just the right amount of sweet versus savory to make this burger awesome. The second go around, I got the falafel sandwich with fries and the goat cheese and watermelon salad. The part I like the most is that, although this is a cash-only establishment, if you ever forget your cash, you can mail yourself the bill and send them payment back. What a trusting company!

Bob W.

Great beer!!! I had the xxx IPA and it was fantastic. The food I had wasn't great though. I had the chicken sandwich and I would recommend sticking with a burger (the burgers looked really good). The service was unconventional but it worked thanks to the servers really working as a team. The atmosphere was great too. The prices were excellent, but be warned they only take cash (they have an ATM if you need it) All in all this place would be a 5 if the food I had was better. I believe the food was an anomaly but it's my only experience here.

Paty D.

Burgers & beer! It's a winning combination & this pub does it right! We went straight off our flight and it was one of the few places open late. It was bustling with college kids & locals and had a great laid back vibe. They have an array of beers to choose from, and they were gracious enough to bring me a few samples. The beers are very reasonable in price with most of them being $5-$7. For my burger, I decided to go with the special- check the board when you walk in. It was a stout bistro burger with caramelized onions & pears cooked in stout beer, with a Gorgonzola cheese. Despite the strong flavor profiles, the combination was harmonious! You have the sweet onions & pears which balance the Gorgonzola, and the stout flavor was perfectly subtle. Service was great. Everyone pretty much takes care of you and you have several of the servers coming around at all times. As to the only downfall- cash only! But definitely a great option in the Boulder area for some great food at a very reasonable price!

You know, I have to say, when I was younger I disliked this place (simply due to the hippy crunchy vibe) but I am glad I gave this place a second chance. I go in and I have a great meal, not expensive and the service is always on point. I would like to formally apologize for being a judgmental jerk in my youth and I am glad I was talked into rejoining your hippy crunchy cult of great food and service. I don't drink and the place is quite comfortable for someone that doesnt indulge in the adult libations. The root beer is quite good and I always feel comfortable.

Sara M.

Servers were friendly and helpful. I'd definitely recommend the chicken nachos, however, if there's only two of you, ask for a half. No one told us it was a large portion, so we had plenty of leftovers. We split the SOB burger and we were not blown away, it was mediocre.

Paul G.

This is the first place we stopped at once we got in to Boulder. It was a Saturday night and there was not a long wait, about 15 minutes. We were able to grab some beers from the bar while we waited. They had a great selection of beers and they offered samples. Which I loved. It was nice to try their beers before you purchase one. The beers were all pretty affordable. Once we sat, the waitress came around with our menus. The food sounded pretty good. I order the special, Alaskan crab Mac and cheese. Sound amazing. My girlfriend order the main burger. I forgot name. The good came out and the Mac was not that good. It looked good but tastes too fishy. I was a bit disappointed almost to the fact I wanted to ask for something else. Soooooo disappointing. The burger was pretty good. I would probably give it 4 stars. Nice bread, slightly crispy, good tasting meat, and tasty fries. But the Mac was just not that good I can't give this place more than 3 stars Don't get me wrong, I would probably go back for the great beers and affordable price but I would stay away from Mac. :-)

Casey S.

Just have to say wow! I rarely if ever write reviews, but their service last night was so top notch that I couldn't help myself. We just moved to the area from TX, and were looking for a good beer and pub location. A friend was in town so we figured we'd give this a shot. From beginning to end, we were shocked at just how awesome this place was. When we arrived, it was pretty packed. I saw a sign about putting your name on the waitlist at the bar in the back. As I was about to head that way, a waitress offered to walk us back there. Then she asked if we had been there before (we hadn't) so she poured us all a free pint while we waited. Oh, and the kitchen made some extra fries by accident, so she gave us those as well. I had the black and blue burger along with a few IPAs. The bill was very reasonable, and I was shocked at how nonchalant they were about their payment methods. So they only accept cash, but gave us a few options. We could use their ATM in the back to grab some cash, or they'd give us an envelope and we could mail them a check when we had a chance. Or heck, he said, just pay next time you come see us. Btw, the food and beer were both very good. We'll definitely be making this a regular visit for us.

Came in from Chicago and had a phenomenal visit! We went on a Friday around 7:00 pm and waited for only 25 minutes. While we waited we had a few of their brews and were offered free pub fries while we waited. We ordered a date night burger and a streak sandwich and were not disappointed! All the food was so good and the workers were all so friendly and fast. Some tips: They have free tastings for all brews! Games are available for while you wait! Free fries!

The service here was freaking weird. Our server either didn't hear (it wasn't loud in the restaurant!) or didn't understand what we were saying. I had to say my order like three times before she realized what was going on. It was like she just woke up or something and was out of it. Actually, now that I think about it, maybe she was sleep walking? I'll blame Ambien for this one. The beers are solid. I especially liked the Rye IPA. The food was kind of meh. I remembered it being better. It's cool they have lots of vegetarian options though.

It's been awhile since I was here, but I really like it. Good beer, good food, good service. Parking can be challenging though, so we usually opt for Southern Sun over this location. However, there are a couple of a parking garages not far, so sometimes we have used those when street parking was too difficult to find. On good weather days, we park further and walk or bike over. Bring cash as they don't take credit cards.

Loved the fresh food, the atmosphere was chill. Was one of my favorite places on my cross country road trip a couple years ago.

Very overrated. Stopped for an okay burger and a grilled cheese that didn't have very good cheese in it and paid too much for all of it.

Excellent beer selection, some of the best I've had. The service was excellent and I liked their team philosophy. Food was excellent and quick. Sat outside which was great for people watching. Highly recommend visiting.

Totally love the happy hippie vibe of this place, but was really blown away by the service last night. Staff was apologetic that things were running a little slow - we didn't know anything about it because as soon as we were seated, they brought out free fries just because they were feeling like they were running a bit behind. I ordered a veggie burrito and wanted it vegan - no cheese or sour cream. I asked for the option to add veggie green chili. Because things aren't labeled super clearly, it wasn't apparent to me (or my server) that the green chili actually isn't vegan because it's made with butter. Before the order came out, another server came by a few minutes later and apologized thoroughly and sincerely that the chili isn't vegan, and that they were going to make me a new burrito and that it would be on the house! Most places would either not tell you that what you ordered wasn't vegan and serve it to you anyway, or realize their mistake and wipe it off or cover it up somehow. I totally commend the honesty and customer service ethic here. The only thing that would improve it would be (1) make your veggie chili vegan! Earth Balance, made right here in Boulder, is just as tasty as butter. Also, is butter really necessary in chili? OR (2) clearly label what's vegan to avoid confusion. Your honesty and integrity earned you a loyal fan, though, and I'll bring all my friends who come through Boulder to Mountain Sun from now til forever. XXOO.

Solid burger joint if you find yourself in Boulder. Food: nice selection of great tasting burgers (including veggie), plus some sandwich and salad options. Served medium - the way a burger should be served! I had the Bison Burger, which was great except for the fact that I have more bun than burger. Ambience: loud crowd of all ages, definitely with some skew to the younger side. Also a little crunchy / hippie feeling, which I dig. Not everyone's cup of tea though. Beer: great selection of Colorado brews, and they even providing free tastings.

Great beer, friendly servers, awesome atmosphere--the food is yummy and great attention is paid to satisfaction at this establishment that honestly cares about providing customers quality at a reasonable price. You can tell that everyone from the host/hostess all the way to ownership take hospitality seriously. Good to note: this is a cash-only spot. They do have an ATM towards the back if you forgot!

Matt D.

By far the chillest place I've ever been to (besides the monk temple in Chiang Dao). This was also our first place on our travels in Colorado. Let me just say... 1. They rotate the artwork - keeping things fresh! 2. They brew their own beer - Craft beer at it's finest! 3. The food is super satisfying and priced appropriately 4. It's Cash or Check only... yes I said Check lol, but there is a little secret if you don't have a Cash, Check, or Debit Card to use at the ATM... You'll have to just go to find out the little sweet-awesome secret Next time I'm in Boulder, you betcha I'll be back.

Passing through Boulder, CO we wanted to check out Pearl Street Mall and stopped for lunch here. Even though it was super busy, the service was wonderful and the food excellent. I had their Peachy Keen Burger which was made with local Colorado beef cooked perfectly, topped with their peach salsa, organic arugula and cheese. We received their hand-cut fries free while we were waiting. Even better, they comp'ed us a free meal because of a kitchen mix-up where the wife's meal was a few minutes late! If I lived here, this be a regular place to visit. They also served great local beers.

This is a fun place to experience Boulder culture. Upon entering, it seems a little chaotic. You have to go to the bar to put your name on the list for a table. But you you can order drinks at the same time. The service is super fast and friendly. I was in town for four nights and came here twice and will stop by next time and I'm town.

The Good: Mountain Sun is a must-try, old-school Boulder staple. Mountain Sun on Pearl Street is the original casual restaurant & brewery -- if you're in Boulder, grab a Junk Burger and craft beer here! They've been in the same spot on Pearl since '93 (!) and have three other locations -- Southern Sun & Under the Sun in South Boulder off Broadway & Table Mesa, and recently opened Longs Peak Pub in Longmont too! The vibe is casual and the place is always packed. Be sure to check out the coolest specials board in town featuring gorgeous, detailed, incredible chalk art by local artist Bryce Widom. The board changes with the seasons like their rotating beers and takes up to 14 hours to produce -- when you see it, you'll know why. The atmosphere is very Boulder, I recommend this spot for out-of-towners to get a feel for old-school Boulder before it got all fancy. Great people watching, lots of locals, no TVs, open layout with taps in the back. They have live music most nights and it gets even busier then, so be sure to get there early and hold it down! The Bad: The place is a well-known Boulder institution and as such, it can be hard to get a seat, especially on live music nights (if you can't get in, go down to the Laughing Goat coffee shop, they have lots of live music too!) I also wish they'd blanch their homemade fries! The Food: Tasty old-school burgers with additional offerings for kids, vegetarians and gluten-free folks. The menu has been the same as long as I can remember - if it ain't broke, don't fix it! They source local and organic food whenever possible, in true Boulder fashion. The Service: Service can be kind of slow -- maybe our mistake was taking up our server's kind offer of free tastes -- we ended sitting at the brewery for twenty minutes without a beer waiting for our seven mini tasters, so it might be a good idea to taste the beers old-school - order a pint right away and get it without delay! Overall: A must-see stop for visitors and anyone who claims to be a Boulderite. Get a burger and a beer and hang out here if you're in Pearl, this place is legit.

This place a so cute! Staff were super friendly and helpful even while we waited 45min to be seated. The custom grilled cheese was delish, I added avacado and bacon to it. Highly recommend just for service alone! Hard to find places in Colorado that truly care about customer service! Check em out!

C T.

I've dined at Mountain Sun more than once, and am always more than happy with the food. Great options on the menu, and they cater to those that don't eat meat or dairy. Also, great beer! The only reason I didn't give it one more star is that they're typically very busy and you will likely not have a very quick dining experience. That being said, this is likely due to their popularity and great food!

First of all, I'm not a big beer fan, so my review will not focus on beer. I went there with some intern friends, we were in a big group so needed like 3 tables, the staff there were very friendly, from waitress to cashier, they only take cash but luckily there's a atm in the place! The place is pretty with a lot of paintings on the wall.

William C.

Wow- all I can say is wow- first the service was superb- the waitstaff was incredible and took care of any need we had. My wife's meal came a bit after the rest (2 min) and the manager comped the meal despite me saying it was OK- The food was great! My kids and I had burgers, and my wife had fish and chips. Her meal was outstanding while the burgers were great- They have a full bar and serve generous drinks! The only caution I would give is they are cash only- but here is the really incredible thing. They have the "karma" envelope- a self addressed stamped envelope to send them a check for your bill if you do not have cash or an easy way to get cash at an ATM - the manager nearly insisted I use the option as I tried to use a card- I was struck by their willingness to delight a customer! Would I go back? Absolutely and I recommend others do the same!

Seriously, after this meal I wish I lived in Boulder! I may never be able to have another burger again because nothing will measure up...my jalapeÃ±o burger was cooked to perfection and I highly recommend the garlic mayo to accompany the fries. The staff was so friendly and accommodating! Great beers and an all around awesome experience!!

Dan H.

Okay....who in the heck made such a great going place as this!! I was in town for six days and was recommended to check this place out by a local local. After the first try....I had to try hard to not come back for every other meal (and the awesome vibe/staff/attitude). Now there is a ton of great foodie places along this way but I was very impressed by the simple way the staff worked and the standard they have. Not sure how to better describe it- I love the idea of having a restaurant, serving great food! in a manner that you get excited about. Alright Mountain Sun, I am taking notes :) F-ing Awesome!!

JJ S.

Ditzy, slow server not fun to work with, unfortunately. Got our order wrong and late. The support staff picked up the slack when I got tired of waiting, however. Free beer for the trouble. Excellent. Very good sandwiches and burgers. Our party was pleased. Good beer selection.

First place I dined on my visit in, and last place I went to on my way out! The cheap prices make this the most affordable, good meal around Boulder around Pearl St area I think you'll find. Very good large portions. Their nachos looks massive! I really loved the fantastic Steampunk-ish chalk mural on the inside wall too.

One of my favorite restaurants. If you go to the bar sometimes they'll give free food! Unlimited samples for beer!

Clayton A.

This place gets five stars for the beer I haven't been able to stop thinking about since my visit: Bourbon Addict Imperial Coffee Stout. That beer was perfection and consumed my thoughts and cravings during my four-day trip to Boulder last month. I want more. I need more. It keeps calling me, man. *Pookie voice This beer was bursting with bourbon notes, oak, dark malt, toffee, vanilla, caramel and of course, coffee, but it all worked so damn well together. Despite the high alcohol content, it was smooth, creamy and full-bodied. It really was a work of art. I also must commend the brewers here for the Belgian Black IPA, as that too was superb. These two beers stole the show. As for the food, I only snacked on a few nachos, but found them to be packed with plenty of flavor. But you don't need food when you have Bourbon Addiction. I have the Bourbon Addiction. I need my fix.

Riesa L.

Great lunch spot. I had the make your own grilled cheese with tomato, red onion, and bacon. So good. The Moscow Mule had lime zest, which I'll be adding to the mine the next time I make them at home. The ginger beer could have had more of a ginger kick, but overall it was a decent drink.

Not a big place and they kind of pack you in, but their beers make up for it. Friendly service and clean. We had 7 people and they accomodated us in a timely manner. I had a Margarita which was fantastic and the rest of our table had beers which are quite tasty. I also tried the Junk Burger, really good beef, they try to get you to order it Medium but I like mine Medium Rare, my burger still came out Medium :( I also asked for very crispy fries, our server forgot, and then brought out a basket of crispier fries but still not that crispy. Not sure our server really listened to our requests but would def go back to try some other entrees.

I judge a brewpub by the beer and fries. I had the Number One and Southern Skies which were the best beers I've had in Colorado. But the fries are to die for. Truly fresh cut. Delicious. Boys loved their bison burgers and chicken sandwich. Cool place.
(5)
Kim M.

One of my favorite places to go to in Boulder. Great beers and food. There's usually a wait because they're so popular. But, the advantage of it being a brewery is you can head to the back and grab a beer while you're waiting. They let you sample any beer you want for free. I've tried most of their burgers and I have no complaints about any of them. 2 of my favorites are the date night burger and junk burger. But my go to order is their spicy pollo asada burrito. It is delicious and a good sized portion - I always have leftovers! FYI it's cash only, but they have an atm in the back near the bathrooms that has a service charge of only $1.
(5)
R G.

This place is extremely popular. It seems to draw it's crowd from the chill atmosphere. The laid back vibe attracts lots of people so be prepared for a wait. If you do have to wait you can get a beer from the bar and order some fries. You may not even have to do that though. When I said this place is chill, part of that came from their habit of giving away free stuff. We had just ordered a few beers and thought about getting fries but the staff just asked us if we wanted some and gave us a basket. That's not the first instant of giveaways experienced by us at this pub. We came in for a late lunch when it wasn't so crowded and they asked us if we wanted to try some new brews. Thinking it would be sample sizes we said yes and we were surprised when they brought over full beers. Pretty sweet. Be aware that not everything is free though. They charge for ranch. This annoys me because I'm a fat kid at heart and enjoy ranch like how most people enjoy ketchup. But after joking around about how little ranch we got for the fifty cent charge, we learned they make all their sauces there, to include the ranch. Considering it was tasty ranch, I developed a respect for the fifty cent charge. Despite the chill vibe and great service, this place only gets four stars. The food is just ok. Yeah the ranch topped it all off nicely but it was overall lacking. Nothing all that special. But if your looking for a place to just hang out with friends and a few beers, definitely check this place out for a hangout.

Lacey M.

Small but cool place. They definitely do not skimp on the toppings here! We watched a few plates of nachos go out while we were waiting for our table and they looked amazing...covered in salsa and black beans. We ordered the cheese fries and there was seriously so much cheese throughout the whole plate, not just on top. They also offer free tastings of their beer at the bar. I ordered the basil blue cheese burger and it was perfect!

Clearly, restaurant selection after camping 3 nights or longer is critical. It's almost a spiritual occasion after eating nothing but cliff bars and "just add water" foods, all while burning thousands of calories. Of course anything would TASTE delicious, but after dreaming about this moment for hours on end: few places fully SATISFY. Mountain Sun is one of those places.

I've been to Mountain Sun twice since arriving in Boulder (which was 2 weeks ago...). Both times, there was a short wait--not longer than 15 min each time--and they offer free beer samples in the meantime! I had the raspberry wheat which was sweet but not too sweet, and I would get it again. To eat, I had the bison burger with fries and the spicy pollo asado burger on the second visit. Both were outstanding! Flavors were unique and worked well together, burger was juicy, burrito was the kind you eat with a fork and knife. This may become a weekly tradition...
(5)
Monica V.

This place is fantastic. I came at a busy time but it was worth a wait. Had the SOB burger and LOVED it. Easiest top burgers I've had and I've traveled a bit. Fries are delish and the service is great. Beer is good. I will definitely come back.

Beer was over carbonated and the fries were soggy; we were afraid to order anything else and left. They were busy, might try again not during peak hours.

Tried to like this place over the years, but it never was to my liking.. Tried it recently again, after a few years, only to be very disappointed. Same menu after..15 years? Too much something in the beer, after two i am hung -over the next day! No credit cards. I get it, they are evil, but hey why not reflect the savings on to your customers..Just saying'. The service is mediocre at best, the system of pooling tips and numerous servers does not really work... Last the attitude of the severs seems to be a bit lazy and pretentious, does not sit well with the oil soaked fries.

Louise S.

The atmosphere is cool and casual, very Boulder. Great beers, great fries, CASH ONLY. There's always a wait, but it's worth it. They brew their own beers, and they're great, so just go to the back and order a beer. BEST fries in town - they also have burgers, appetizers, fish and chips, soups, vegetarian choices, etc. Specials menu changes frequently. Staff always seem happy, pretty hip. I've heard Mountain Sun has great management - either way - t's a good feeling place. For the love of god, BRING CASH. Update - we went to the South Boulder location. Not realizing there was a cool upstairs just like the Pearl location, we sat in the more formal and quiet downstairs. Food was great as always.

Saw the reviews on Yelp for this place, and people raved about some of the best burgers in Boulder. They were right! Amazing food, and the hand cut fries were some of the best I've ever had. Nothing at all compared to the service, though. The wait staff was friendly, laid back, joking and easy to get along with. Quick to check on tables, and attentive. Great Boulder lunch experience, thanks!

Rarely do I give anyone a bad review. I still don't want to. For the most part the service was good, the atmosphere relaxed and fun, and the beers were great. I ordered some pork belly tacos that the server said were a favorite. Maybe I don't know what pork bellys are, but what I bit into looked like a giant frenchfry but was pure gristle/fat. I was taken aback. I threw it off my plate thinking maybe I just had a bad piece. I almost threw up. I had one or two more bites that were really good. Tasted bacon/hamy/meaty. But after three more "gristle fries" I picked all the "meat" off my taco. For $13, three tiny tortillas with some crunchy cabbage and a little dressing didn't cut it. Everyone else seemed to enjoy their meals. I'm willing to give it another chance but would caution against those pork belly tacos. It wouldn't be difficult to use some really good shredded pork.

Jade Q.

I checked out Mountain Sun again, and this time I actually really loved everything I got. My friend insists that I had just been ordering the wrong things. This time around, I ordered the Glider cider, which was very good. My friend and I ordered a basket of fries as an appetizer and requested ranch and jalapeno aioli as dip. The fries were delicious, as were the dips. The aioli was super good, and the ranch is actually truly awesome. They make it with dill, which really takes it up a notch. I ordered the Junk Burger except with a vegetarian patty and no bacon. It was super delicious. I also ordered it with a side of the soup of the day, which happened to be tomato bisque. All of it was amazing. I thoroughly enjoyed my meal and had a few leftovers which I just ate now. I suppose my last review was due to ordering the wrong food in the past. I still would not recommend the black bean chili nor the Reuben. Burgers are what they really excel in, and I don't even like burgers, but they do it right. Lastly, I was very excited to see that they took that Cupcake wine off the menu. *phew* Service was great, and I can now say I see myself coming back in the future.

ETA: I bumped my original rating up from two stars to three, because the next time I went, the owner and staff went very much out of their way to make sure my friends and I had a nice time. I will also admit that the french fries and beer are hard to beat. I'll probably get kicked out of Boulder for a two-star rating here, but I haven't had great experiences at Mountain Sun. I want to like this place more than I do. The service is consistently slow, and I just haven't had good meals. I know many people love it, and it has been a local favorite for many years. I'm not impressed. One time when I ordered the vegetarian chili, I thought the meal was reasonably good. I hate to say that it's the only time I ended up really enjoying what I was served. If you go, do it for the beer and party atmosphere. Also, the fries are pretty good. Be prepared for a long wait getting seated, a longer wait getting your food and for mediocre meals. The good things about this pub and brewery are that the ingredients are fresh, and the people who work there are usually very nice. I do appreciate that. If I could add an extra half star to my review, I would, just for those two reasons. Go with friends, not to have a great meal but to have a fun experience.

This place rocks! Great food and great brewpub. There was a bit of a wait and one of the Manager brought us some free fries while we waited. The staff was wonderful from the bar guy serving beers and letting is sample to our servers being helpful with refills and other stuff. Great place!

Keely B.

During my visit to Colorado a friend suggested that we have dinner here. It was about 8 or 9 pm and the place was crowded! While we waited for our table the bar lets you sample any beer you want, so we tried quite a few. The selection was great and all local, which is something I really like. The atmosphere was great, although fairly loud. The food was good as well, I definitely recommend the vegetarian chili! This place was interesting, however, as they only accept cash. They do have an ATM near the bathroom, but I heard that they will also send a bill to your house. I thought that was quite unique. They lost our ticket when we went to pay, so they took care of all our drinks, which was unexpected, but nice! I was speaking with the owner of the restaurant while waiting to pay and after finding out that I was from Oregon he said that the restaurant was modeled after McMenamins, which is one of my favorite places from home. Great experience!

Cassie R.

Really amazing ambience and staff. The "team" of servers who take care of you are friendly and funny and very efficient. The beer is great and very reasonably priced. I had the avocado and cheese sandwich with fries and my boyfriend had vegetarian black bean chili and tomato bisque. I would definitely come back! The fries are all natural and very tasty. The java porter was also perfect.

Rachel D.

This was one of the only restaurants open at 11:15am on President's Day, so we gave it a shot. Really enjoyed the decor and style of the place itself, plus they made some damn good bloody mary's. Unfortunately, our food was staggered and I ended up waiting 5-7 min after my boyfriend had finished his burger to get my grilled cheese (which, also unfortunately, had been ordered wrong). Pretty inconvenient that they didn't take any cards, either. Our server was okay but not very attentive and sounded like he was half asleep (maybe that's why my order was off...).

Atmosphere, staff, and food - all 5 stars. In addition they have live music (at least on Sundays), gluten free bread, and free samples of beer! I think I tried 5 or 6 different beers before picking one. Our guy really knew his stuff and loved what he does. The French fries are a must - do not leave without getting some. We both got sandwiches, and they were perfection. The burgers, chilli, burritos, and basically everything on the menu looked amazing, including dessert. If I was a local, this would definitely be a spot I would go to regularly.

Chris W.

Love this place! We almost always hit the Mountain Sun or the Southern Sun on our way home from Skiing. Nothing beats an FYIPA and a junk burger with fresh cut fries when you're tired and hungry. It's always worth the wait so be patient and order a pint to enjoy until a table opens up.

We were once huge Mountain Sun fans, back in the day. I still have a soft spot in my heart for the friendly hippies, the overwhelming nacho plates, and the casual attitude. But we are now older, and I find that the noise level is difficult, so we don't go as often. And there are many new brewpubs in Boulder to compete. It is a great place to take kids, because they can't possibly disturb anyone, and its a fine place to sit down after work, hoist a pint, and have some of those aforementioned giant nachos. There is also a chalk mural by a local artist that is updated regularly, and it is always charming.

Mary K.

I'm lovin the Mountain Sun. Great staff! Thanks so much to the waitress who bought us a round of drinks because we were from NY, so sorry we didn't get a second round! Burgers were out of this world. Free fries instead of bread which was AMAZING. I will definitely return next time we are in Boulder!

Excellent service. Went here with a buddy while on vacation in the Centennial State. Arrived at MS at around ten p.m on a Tuesday night. We had just spent about nine hours hiking in Rocky Mountain National Park, got caught in a huge storm and were in desperate need of food and drink. As we were seated by the hostess, a gentlemen who I believe was the manager/owner, informed us that the kitchen was closed and asked if that was a problem. Bummer. We informed him that we indeed had come to chow down. He was kind enough to have the kitchen remain open for our orders, which is above and beyond in my book. My buddy ordered the speakeasy steak sandwich and I the S.O.B burger. Could have been that we were famished, but our plates were awesome. Everything tasted fresh and as others have noted, the fries are great. Also, ordering a burger medium rare and actually getting a burger medium rare was nice. It seems like many restaurants have a problem understanding this concept, God help us. My buddy's plate came with a cup of soup, and while I can't remember the name and I didn't try it, it consisted of veggies, Italian sausage and a tomato-y broth. It looked delicious and he said it was bad ass. Our waitress was very sweet, professional and helped us pick out one of their awesome brews. The cash only policy of MS almost became an issue when we were trying to pay our tab as we only had cards. The owner/manager? did something unbelievable. He said we could mail him the cash. Whaaa? That kind of customer service is unheard of in this day and age. Granted, we went to the ATM so we could pay the man, but his approach left us both very impressed. Keep up the good work, Mountain Sun. I would love to come back if I'm ever in Boulder again.

Cash only is mildly annoying but I get why that's the case. Good black bean burger and beers.

Friendly service, great burger and amazing fries. All the good reviews are correct and mine is no different.

I absolutely love this place! They have great vegan options and it's a very chilled out atmosphere. You seat yourself and they work off of a team system so you don't have to rely on one waiter. You do, however, have to pay in cash or check (there's an ATM in the restaurant) but if you don't have either they'll send you home with a stamped envelope to mail in a check later on. The food is delicious (best black bean burger I have ever had!) and they have an incredible selection of beers!

I'm from Pittsburgh and just moved here. I sat in by myself, was greeted by the manager and we talked for a bit about the food and beer. He didn't seem the slightest bit rushed and answered all of my questions. I didn't realize he was the manager, and said that I'd start with the cream stout. Shortly after I was greeted by my server, and we had another good conversation. The manager then brought me the beer, told me it was on the house, and said welcome to town. I know exactly why I moved to Colorado now. By the way, the Asada Burrito is perfect. I can't wait to come back, and I haven't even left yet.

The service was pretty good, the food and drinks were also really good. However, the reason I'm rating this a 4 instead of a 5 was the price we paid for our half order of nachos which I thought was ridiculously over priced. Yes they were good, but not $11 good. A full order is $12.75, and a half is $10.75, for literally half the size order only saving $2. If I would have known that, I would have just paid the extra $2 and got twice as much. $8.75 is a good price, but not $10.75. Lower your price! I did mention it to a waiter, he agreed, but did nothing about it.

How can you not like this place? I'm not even a beer person, but I always find one that I end up liking. The only issue I've faced is the wait, but it's completely understandable.

This place is amazing!! We walked in at a very busy time and they were extremely friendly and fed us free samples of beer and fries for our group of 7. Every server was very friendly, the beer was awesome and the food was excellent!! If I could give it more than 5 stars I would. Love this place and will come back again and again.

Reyana F.

randomly yelped this place while i was waiting for my friend to get out of work and it was amazing. from the outdoor seating that still felt casual, to the homemade hummus and the impeccable service, my boyfriend and i had the best experience! the break down: service is extremely friendly but definitely the typical boulder friendly guy who knows his beer and looks somewhat like someone famous. the food is like typical bar food but super delicious (junk burger and you won't be disappointed). they also cut our burger in half for us! maybe i've been in SF/NYC for too long, but i loved the friendliness and laid back vibe of this place. pitchers of FYIPA are a must.

Nima A.

Excellent burgers, incredible beer. The ambiance is so local and fun feeling. This place is really killing it!!! I came here on a triple date with a group, and we had a blast! We all ordered burgers and a few pitchers of delectable craft beers. All was great and we had a blast. Service was excellent as well. The reason why I gave four stars rather than five is because this place is CASH ONLY. Major pain, especially for a sit-down restaurant in this day and age. It doesn't help that I'm an accountant. Cash-only = up to no good in my (and the IRS's) eyes.

SO COOL! I couldn't stop studying the beautiful artwork on the walls. Employees were SUPER friendly, beer was excellent and there was a great crowd for a weeknight. Didn't get to try the food, but that's an excuse to go back.

My friend from Atlanta came to visit and we decided to dine here since the yelp reviews were great. It was packed in a Friday evening and we waited about 20 minutes for a table. They were so busy, but everyone in the staff made sure we were well taken care of. I ordered a Bloody Mary which was just average. My friend and I both wanted to venture out and order something that sounded a little crazy. So we both got the Date Night Burger. Thank goodness we did because it literally was the best burger we've ever had! Their fries are also wonderful because they cut their own fries every morning.

Shelly D.

Love this place - plenty of veggie options and endless beers on tap. They even have a "karma envelope" since they only take cash or check. If you have no way to pay for the bill, they'll give you this envelope and you can mail it in! They said they have a 99% return rate on those checks! Fantastic idea! I heard they have bluegrass on sunday nights, will check that out soon!

We were referred here by the Prana store employee down the way. Since he was a "local," we asked his advice on stuff to do in Boulder the day we visited. Mountain Sun was a solid recommendation! The vibe as soon as we walked in was welcoming and homey. It was only 5pm or so on a Tuesday and it was so busy! The manager/host seated us right away and we were immediately approached by a waitress. At no point were we made to feel like they were too busy to deal with us. We got our beers quickly and ordered some cups of chili and soup. Both delicious! Homemade soup is the best in the rain. Prices were very reasonable. This place is a must-visit in Boulder. Thanks Prana guy!

We came here on a Sunday night after a long drive from Aspen, and were immediately greeted by a very friendly waitress who led us to our choice of table. The place was huge, could easily have a large party there! We were handed beer menus and left to deliberate on the massive amounts of beers they had on tap. We were lucky enough to come to Mountain Sun during Stout month, where they had a ton of different stout beers on tap. Seriously the most delicious stouts I've ever had! The waitress was extremely friendly, she offered us tons of samples/tasters before we decided on which beers to buy - very generous pours of beer. I tried several stouts, coffee/bacon/chai tea/peanut butter. I liked the chai tea stout the most, as it hd the most unique flavor, but honestly all the stouts were very high quality. We ordered wings, which were delicious and a very large portion for a group of 4 to share. This place has seriously some of the best beers on tap and i would definitely consider coming back here when i am back in Boulder.

Loved it. Everyone was nice, the food was good, the beer was great. But the extra perks were what did it for me. Even though it is often busy, they give free samples of their many brews while you wait.

Great casual spot in Boulder with super friendly service, good beer and awesome food. I'm in town for work and looked up a cheap spot in Boulder that served beers (lots came up) but I'm glad I selected Mountain Sun Pub & Brewery. My waitress was great and we talked about beer quite a bit and she gave me a small beer sampler before I chose which pint I wanted to order. I got the bison burger with fries and it was delicious. I could have made a meal just on the fries so definitely get those.

Marissa B.

Love love love the Junk Burger. The restaurant has a great low key vibe, good beer, and excellent food.

Kippy D.

Yes, it is that good. The server let my sister and I sample a few more beers, small samples and we finally found a couple to settle on. I had the eggplant parm sliders, so freakin good, I wanted to cry. Sis had a bison burger, that's what she was in the mood for. It had bacon on it. She wanted to cry too. So incredibly good.

Kevin K.

Probably the best beer in town (and that is saying a lot). Mountain Sun usually has 10+ homemade beers on tap and they are first rate. The food is pretty good (slightly hippy, slightly burger joint). Some folks love the food, but I think the beer has to be the reason to go! This joint is often CROWDED! Especially after 5pm. Be ready to stand around drinking a good beer for 45min to 1 hour while you wait for a table (if the beer wasn't your goal to begin with). The fact that its crowded reflects that it's good stuff in a small restaurant. The wait staff is nice. You can ask any employee walking by for help (or more beer) and they'll get it for ya. Be ready, this place is CASH ONLY!!! They have an ATM you can use, but as with all non-bank ATM's be ready to eat some fees that add up if you don't have cash.

Lori S.

Great food and beer. Unique all around. I had their eggplant sliders on sweet potato buns, delicious! The arugula, feta salad that came as the side was excellent. Wish I could have tried more of their beers. Next time I would order their six beer sampler. Full house at lunchtime on a Monday says this is a favorite place for locals. Note that they do not take credit cards, but there is an ATM or they will trust you to mail in your check!!
(4)
Steve S.

Definitely a cool place to go on a weekend night just because of the atmosphere. This place was packed! This isn't a traditional pub; more like a hippy drum circle that also serves beer and food. I find that atmosphere comforting, don't you? The beer is cold and tasty, to match the pub-style meals. Don't expect Frasca Food and Wine, but do expect meals better than your normal pub or sports bar. One little note - Mountain Sun does not accept credit or debit. So cash up otherwise you'll be staring at other people's food.

ONE CAVEAT TO START WITH!!!!!!!!!!! This place doesn't accept credit cards. But they don't make that clear up front. Extremely bad policy- the server should tell the customers right at the beginning. Why don't they make it clear? Because the place makes more money that way. How? If you find out at the end of your meal that cards aren't accepted, you can use the ATM in the place to get cash. The catch? There is a $5 service fee for every withdrawal. MS is making money hand over fist just from that darned machine. Kind of unethical. Payment policies aside, this place isn't bad. Nor is it particularly good. Since it is a brewery, I'll start with the beer. We tried the Brewery Taster, which consisted of 6 small pours of 6 different beers of our choice. They were all warm. A negative right from the start. As for the quality and tastiness? Eh. We've had much better beers at many other local breweries. This place ranks far down on the scale. Won't return here for the beer. Won't return for the food either. It was entirely average. Sweetie had the black and blue burger, ordered medium rare. It came out well-done. The blue cheese didn't taste like blue cheese. It simply tasted like a horrendously salty mass of something unidentifiable. The blackened seasoning didn't taste like anything in particular, nor was it particularly good. I had the buffalo chicken sandwich. Same blue cheese (or, should I say, same salty non-blue cheese). The chicken was way overcooked. Not very good at all. The service was extremely odd. I'll give MS kudos for attempting to have good service, but, oddly, their efforts fell way over the mark. Multiple (3) servers were assigned to help us throughout our meal. I'm sure that this policy was created with very good intentions- an attempt to ensure good service. But it backfired. For instance, we placed our drink order with one server, and then in the next few minutes, each of the other 2 servers came by to take our drink orders. We had to tell each of them that we already had been helped. Same thing happened when we ordered food. (There clearly was no coordination of any kind between the 3 servers.) Then, throughout the meal, each server came over numerous times to see how things were, and if we needed anything. Again, very good intentions. But what ended up happening was that literally every two minutes, someone was coming to the table. We couldn't hold a conversation. After about half an hour of this, we simply wanted to get out of there. We left a very good tip, based on the good intentions. But by the time we left, we were kind of twitching when someone approached the table for umpteenth time.

I was in town for the week visiting my sister and her fiance took us here. The burgers were excellent, fries amazing, beer selection top notch. I can see why this is a local favorite. We came right before the lunch rush so we didn't have to wait long to be seated. Nice place and I would definitely come back here if I lived local.

Lacey R.

Wonderful experience!! Crowded, but found a table right away. Very friendly staff and overall great vibe. Awesome beer selection and the good was amazing. I only wish I had room to eat it all. They have great deals and also games to play at your table. Don't have cash or a check? Ask for a karma envelope! Pay later!

Upon entering Mountain Sun, you are told to sit where you like. I arrived before lunchtime, having a feeling that the place would fill up quick at peak hours. That was smart on my part, as it did. While eating you are helped by a rotating cast of employees. This is unique, and assumably helps to provide timely service. It allows the patron to have a little face-time with many of the servers buzzing about. Its nice, if not a little impersonal. There is an amazing selection of local craft brews on tap. The servers have educated and personal suggestions. The food caters to just about everyone. I ordered the vegan ruben out of curiosity. It was a solid B, if I was a vegan, I am sure it would score higher. It is of note that they only accept cash or local checks. Thee is an ATM on the premises with a low-enough surcharge. Here is the thing though, (and this really is the thing), they offer the patron-in-a-pinch the option of mailing payment for the meal via mail. Furreal. I was offered the option upon seating. Thats fantastic. So rarely do you actually feel trusted by the establishments you frequent. This reviewer concurs with most of the others; Mountain Sun feels like home. A must frequent and a welcome alternative to the pricey and impersonal options in the downtown Boulder area.

First time at Mountain Sun. The atmosphere is very relaxed and friendly. The menu is broad and caters to all appetites. My Bison Burger was cooked to perfection with crispy bacon. Their bbq sauce is perfect, sweet enough without a overly vinegary flavor. My friends had the Boom Boom Sandwich with bacon and absolutely loved it. The S.O.B. Burger was cooked to perfection and the bun didn't slide off even with the jalapeÃ±os. Fries were fried wonderfully and weren't skimped upon. While they don't accept credit cards, they have plenty of work arounds. Overall, a fantastic experience with great beer and a perfectly mixed Moscow Mule.

Bill C.

My wife and I have never had a bad experience and Mountain Sun/Southern Sun. If I had one quibble, it's that getting a seat at Mountain Sun can be tricky, due to its smaller size. We usually go to Southern Sun, where its easier to get a table.

We were in downtown boulder on vacation and didn't know where to go to grab lunch. After reading the reviews on yelp, we knew this was the place. We were greeted right away and since a table wasn't ready, they suggested we head to the bar for a few free samples of their brews while we wait. You could tell that the bartenders and wait staff definitely enjoyed their jobs... they were laughing and joking with each other and the customers. I finally decided on the Date Night Burger (pablano peppers, bacon, goat cheese and date puree) and it was fantastic! I definitely recommend this place - between the food and the atmosphere, it was a hit!

Alice L.

I LOVE Mountain Sun! I went back to Boulder last month for a visit (I am a former CU student) and I planned to eat at Mountain Sun in advance. It was just as good as I remember. Our waiter was Tokyo and he was so awesome! He was attentive, knowledgeable, and was truly passionate about MS's beers. He made some excellent suggestions and continued to follow up with us to see if we were enjoying our meal. He also made us laugh really hard (something about a polenta special... I wonder if he remembers :) ). I love spending time at MS because it's a really positive and laid back environment. You can tell that they have a lot of regulars and everyone is beyond friendly. All that and I haven't even talked about the food and the BEER! Their chicken quesadilla is perfect, in my opinion. It's not your run-of-the-mill quesadilla that's overstuffed with cheese - it's proportions are perfect and the ingredients are fresh and SO tasty. The salsa on the side is so delish! The beers are beyond excellent. Be clear with your server as to what you like and they will take good care of you. We did a flight and chose a few ourselves but asked Tokyo to throw a few of his favorites in there too. The ones he put in were probably our favorites. You can't go wrong!! Excellent service, chill environment, delicious food and super reasonable prices. MUST TRY IN BOULDER!!

To be fair, I'm not a big beer drinker so this review is about their food. I had a burger and fries. It was okay but wasn't memorable and was greasy enough that it upset my stomach. I also tried their carrot cake and I must have gotten a bad piece or something because it tasted stale/old. I will say that my beer drinking friends do love going here.

Place to go for local craft drafts, the food is ok for vegetarian selection. Good prices, this place does not take credit or debit cards. ATM in the back, if you wanna pay to get your money. Bring your checkbook if not~

Bill C.

I would normally give three to four stars to a place like this that does have good food and beer. The service was fair to slow with different things forgotten that we ordered. BUT THE BIG ISSUE IS "WE ARE CASH ONLY". There is no sign and no mention of this until you pull our your credit card to pay the check. Then they tell you there is a cash machine in the back you can use. Stupid and deceptive is all I can say. We will NEVER be back. Too many other choices that are just as good if not better.

Anthony E.

We walked in and noticed the sign to seat yourself to a clean table. Given it was lunch time on a weekday there were no tables available. With hungry kids we decided to step out and yelp other restaurants. Then one of the waitresses came out and greeted us to come back in and that they would arrange a table very soon. So glad they could seat us because it was "Stout Month" and wanted to try out their beer. Had the "Oatius Prime" and their "Stoked Oat". Customer service was very friendly and the Patrons were awesome too. We ended up sharing a table with a couple of my distant Work Colleagues which was pretty cool. Definitely recommend this down to earth establishment for anyone visiting from out of town or for a simple bite and a beer ;-)

Ron R.

Super friendly / efficient wait staff. First time this week. Came in from article on stout month. Fun sunny outside seating. Busy noisy inside. Fun. Had nicks famous hamburger. Was good. Bought a flight of 4 house stouts. For my taste Megatron stout blew my other 3 stouts off the map. Had one of their nitro stouts. Still a left hand man. Cute fun cool rockin brew pub. Just as they all should be. Go. You'll have fun.

Lana S.

Not as impressed as others. The place does have a great atmosphere, lots of young college kids. My broccoli cheddar cheese soup was A-OK, it lacked the creaminess one would expect from that type of a soup. The sourdough bread in my sandwich was not fresh unfortunately. The chicken and veggies in the sandwich were awesome though, but overall the food was lacking in taste and flavor. My boyfriend's burger was plain and boring. The french fries were soggy :(. On the other hand, our waiter was awesome, very knowledgeable, super friendly and attentive. So five stars on that.

This is, without exaggeration, the friendliest place I've ever dined. I was shocked by how nice, accommodating, and attentive the staff is here. I wish I could move to Boulder so I could come here all the time. I got the Bison Burger and it was great. Everybody I was with loved their food. The fries are amazing, especially when dipped in the ranch/buffalo sauce, which we did not ask for but the server just brought it out because it was his favorite. Come here.

James C.

This place is awesome. Our waitress was so friendly and so interested in getting us to enjoy their beers. The first thing she said was that we can sample anything for free and seemed disappointed when we knew what we wanted immediately. When looking for a second beer I asked to sample two other beers and instead she brought me 5 more to try. My friend ended up sampling about 7 all on her insistence. The food was fine, I did t think anything amazing but it was definitely satisfying after a day of climbing. They have a perfect fry policy which is pretty cool. I didnt think their fries were exactly how I like them but it's just their style I think -- no need for a redo. Anyways I really enjoyed my meal and drinks there (oh, the beer is quite cheap during happy hour). I pulled a half star because I wasn't amazed with the food but it definitely wasnt something that would steer me from the location again. EDIT: I've been to Mountain Sun many times since and it really is a great place. I still think the food isn't amazing but it's good and satisfying for sure. The service here is phenomenal though. The servers love beer and love helping you find beer that you love (and they have plenty of good ones). I would say this place consistently has the best service of any restaurant I have been to in my life, regardless of price. And for that reason, I am changing my review from 4 stars to 5! This place would rank high on the top places to eat, anywhere.

Megan S.

We enjoyed lunch at Mountain Sun after a morning flight. What a welcome to Colorado! A friendly server directed us to the beer tastings and specials menu. The pork specials (sandwich and platter) were wonderful- flavorful with a nice amount of spice. The fries were perfect, some of the best I've had anywhere. A great start to our long weekend in Colorado!

Travis C.

Absolutely love this place. The wait list is at the bar, so it's easy to enjoy a beer while waiting for a table. The restaurant is stocked with books and board games to play with friends over a beer or while you're waiting for food. The staff is very friendly too. Just remember, no credit cards! Cash only.
(5)
Kurt L.

A great place. The wait staff is friendly and courteous and the food and beer are great. Two things wrong with this place, though. The first is not that it's CASH ONLY, which isn't a bad thing, but that there are NO CONSPICUOUS SIGNS AT THE FRONT INDICATING IT IS CASH ONLY. So, if you're not aware (as was the case with me), you could sit down, have a great meal, and then find out you have to go to the ATM in the restaurant, pay exorbitant fees, and pay your bill. The second is that, while the wait staff is great, the service is INCREDIBLY SLOW. Other than those two, great place.

Brittany S.

We loved this place! Great service, great food, and great beer. I really liked the FYIPA. We had to wait a couple mins for a table, but they made sure we had drinks while waiting. One thing we didn't know beforehand--they are cash only! This caught us off guard and I'm so glad I just happened to have cash.

Mountain Sun Pub & Brewery is a loud, cash-only local brewery that brings to mind the 90's Smash Mouth #1 hit "Walkin' on the Sun" with it's iconic twist of hippie ideals suburbanized into commercial success. Mountain Sun is a micro-brew where every employee does every job and you'll find a menu of vegetarian & healthy choices mixed with classic American burgers and Mexican burritos. And they folked out with guitars around a bonfire Just singin' and clappin' man what the hell happened The "Team Service" concept works as we rarely were without someone checking in to help. Of course, half the time, we simply said someone else was already "handling it." Hooray for a co-op that actually succeeds in meeting the needs of all. You might as well be walkin' on the sun One of the "friendly many" offered to bring some free samples of beers to help choose which one matched our moods. We sampled Free samples of Blackberry Wheat, Colorado Kind Ale, Illusion Dweller I.P.A., FYIPA, and Quinn's Golden Ale. Olivia Z. got the Blackberry Wheat while I had the Illusion Dweller IPA followed by a Colorado Kind Ale. There is definitely a beer or four here for everyone and with free samples, how can you resist? Well, my mom the rebel can and got a red wine since she's not a fan of beers. It ain't no joke I'd like to buy the world a toke And teach the world to sing in perfect harmony Oliva got a bowl of the Vegetarian Black Bean Chili ($3.95) with the Cheese add-on ($1 extra). It was gooey and thick though a tad too sweet for real Mountain Men. We split an appetizer of The Pub's Famous Fries (Med. $2.75) which are fresh cut and served hotter than the sun. They needed lots of salt, so, we added plenty of sprinkles for some flavor while eating them carefully not to burn our fingers or tongue. My mom's order of the house specialty Tim's Blackened Chicken Quesadilla ($8.50) was as tasty as it was huge. They brought a large plate with covered with guacamole, salsa, and a half-moon of quesadilla. It was the perfect size until the server said he'd bring the other half once we finished this one. What other half? Yikes... we better share. She ate half and we ended up getting the rest to go. For me, a burger was calling my name so I answered with the Jalapeno Burger ($8.00) and an extra side of Green Chilies ($1.25) for some kick. The bun was too trivial while the 2/3 lb. of beef was parched. Luckily the chilies and cheese brought some moisture to the sandwich. A-ok, but not groovy. And if you follow there may be a tomorrow But if the offer's shunned you might as well be walkin' on the sun I'm a much bigger fan of Mountain Sun Pub & Brewery than I am of Smash Mouth. The brews were brilliant, the service was synergetic, and the food was filling. We left quenched and headed back out into the Rocky Mountain sun to enjoy the rest of our evening. You might as well be walkin' on the sun.

One of my favorite places ever. Amazing beer. Resinous Rye brewed on-site is my favorite beer. FYIPA is known to many far beyond Boulder. The food is terrific. The atmosphere is awesome. Just go - you will enjoy yourself, unless you are a soul-less stuffy jackinape that simply cannot have a good time.

They have the NICEST staff ever. Every single person that we talked with was just so nice! It was a beautiful day and the restaurant was packed for lunch. We put our name on the list and went back to the bar to get a beer. At the GABF the night before we had tried their Big Boi Bob Imperial Chocolate Stout so I was happy to get a full sized serving while we waited. Delicious!!! Once we were seated we had another nice server. Out of this world nice! We ordered the pub fries, the spicy chicken burrito and a burger. Unfortunately it took quite a bit of time for our food to come to us. We ordered the fries to come out before our meals. The fries were great, but our entrees came out so quickly after the fries that I felt overwhelmed with all of the food on the table. My burrito was good, but I wish I would have gone for the green chili instead of the red sauce. The sauce was a bit bitter and I ended up just wiping it off my burrito. The inside of the burrito was tasty and the serving size was HUGE. I could have easily split this with my date. I ended up just mostly eating the inside of the burrito because the tortilla got a little crunch on the end and made it a little difficult to eat. My date loved his burger and wiped the plate totally clean. I would definitely return, even if just for a beer and fries! Why can't every restaurant be as friendly?!

I had a special which was a fall veggie wrap and it was delicious. Very fresh!! My husband had the tomato bisque soup and a sandwich which was also very delicious. We really enjoyed our experience here and would highly recommend since it is a little off the Pearl Street Mall but not by much.

While the food is better than average, the server took forever to do anything. Even bringing condiments for our food took almost 10 minutes and it wasn't busy at the time. :-(

Good people, good brews, good bands (when they have them). All around friendly down-to-earth wait staff. We didn't order any food, so can't speak on behalf of that. One warning: the crowd is super young (early 20s)... But all in all, great spot to hang.

The hippie decor jumped up and hit me in the face the second we walked in. Whimsical seems too unforceful a word, your assaulted by murals of laughing sun & moon symbols surrounded by a earthly paradise. This is the type of place you expected from Boulders independent reputation and its authenticity seems irreproachable. Beer is brewed in-house and has depth to satisfy staunch beer snobs. I partook of a night colored libation boasting of high ABV, there was no doubt in my mind the match was pre-ordained as I felt myself relax in its enjoyment. I also tried the Junk Burger(5). The patty seemed generously round and thick I would guess 1/2lb. Bacon crisp and cheddar sharp. I took this one from the servers recommendation and clearly he knew me well. A required stop when i visit Boulder again.

By far the coolest beer place I visited in Boulder. I felt very at home there. It was a friday night and every inside seat was full but there was a streetside bar on the sidewalk. I asked some people who were local what I should try, they made suggestions. My waitress let me try 4 beers ( generous tastes too! ) with no pushback. I settled on the Pater's Belgian. Good choice. I then tried the Colorado Kind ale. They had an amazing beer list to choose from. I really liked the service concept here , everyone does everything. I had different servers, but they kept my order with me, not the wait staff , so for example I was like" I want to try that second one I tried, I dont know what it was called" and the alternate waiter says ." it's written down right here - in order " YAY They are cash only, but there is an ATM in the back that only has a $1 charge. I did not try the food. Will next time. Great staff, great beers.

Thumbs up on the food, thumbs up on the beer, thumbs down on cash since I never carry it... but I'll still give it 5 stars.

Always is a go to for all around atmosphere, beer, board games, burgers, and music. Get ready to take your shoes off and kick it on the floor when live music is in town :)

My husband and I were driving from Denver to Estes Park by way of Boulder and decided to stop here for lunch based on Yelp reviews. The place was packed when we walked in so we waited at the bar where the staff was incredibly kind and helpful. My husband and I tried almost every beer they brew and the staff was so kind. We ended up with the FYIPA and the Tripel both of which were delicious. We had burgers for lunch and they were wonderful. The fries were so good! The kitchen made some extras and they gave them to us for free while we were waiting at the bar. We only ate a few before we sat down and they were so good that we added more to our lunch orders. Great spot!

I love this place! It's one of the first places I ate at when I first moved here. I've been meaning to write a review for it as it's been burning a hole in my metaphorical yelper's pocket! Consistency is so important to me and I'm consistently satisfied every time I come here. Anytime I have a visitor, I make a mandatory trip to Boulder to take them here. The wait for a table? What wait?? There's really no wait when you get to sample all their beers until you settle on one in the back at the bar. IPAs! So many IPAs to choose from! It's IPA paradise for me! The bartenders are quick and friendly! They're never resting and always pouring! When we sit at our table, we order a basket of fries - pretty much devoured right after they are set down... And I just can't help it. I try to be adventurous (monterey chicken, burgers, gooney bird..), but ever since my first time at mountain sun, the spicy pollo asada burrito is just the thing for me (hold that sour cream! and spicy red sauce on the side please!). I love spicy and boy can that red sauce get spicy! Technically, I've tried most of the burgers...I "tax" my visiting friends with a bite of theirs..you know, just to make sure everything was prepared ok. And those burgers always are! But in the future, I'll still need to taste test... just to verify... Amazing service here! If you've ever read any of my reviews, you'll know that poor service is a pet peeve of mine and I really don't think there's any excuse for it. This is not an issue here. It's always crowded and I'm ALWAYS impressed at how attentive my servers are to me. I remember once they forgot to put the spicy red sauce on the side. I didn't even mention it to the server (no big deal), but the manager noticed and personally came by and said "we're so sorry! do you want a new one?" I appreciated that he took the time to try to fix the error. I declined, seeing as the burrito was still utterly delicious (I just had a few extra beads of sweat). He comped my beer - no complaints here! Hmm...maybe it's time for a trip up to Boulder soon.

Mountain Sun is easily one of the best breweries in boulder. If you are looking for a great IPA, come no farther. They always have a great seasonal selection of many different beers on their menu and they are reasonably affordable. I also really like the food. Their burgers are very good, I highly recommend the Junk burger with an upgrade to fries and a sampler of different beers. Cash only.

Joseph S.

Food is good, beer is really excellent (especially the FYIPA). The only problem is it's too noisy to hear the person next to you, so sit outside if you want to talk and it's not too cold.

Loved this place! Being from out of town, i don't know that we would have found it without Yelp. It's on Pearl Street but a bit further down from the crowds and action (not a bad thing). I love the relaxed hippie friendly vibe. The food. beer and service were all excellent. I got a steak salad (daily special) - grass fed local beef, crisp peppery arugula, blanched green beans sourced locally and pungent bleu. A classic combo but very well executed with high quality ingredients. The beer was really great and I'm not a big beer gal. Per our server's recommendation, I did a half and half ginger beer and blackberry wheat. Very unusual. Highly recommend whether you are visiting Boulder or a local.

Amber N.

Busy busy. We really liked the beers here and the vegan burgers were good. It was very crowded and loud, but that was fitting for the environment of the place. Doesn't have much standing room or a bar area and I would feel guilty taking up a table just to drink. Otherwise, great place!

Thoroughly enjoyed this place from the service, to the beer, to the food. Im a fan. Worth waiting, worth paying in cash, worth a few workouts to burn it off. All in all I round up a 4.5 to a 5 and will be back!

People love it, but I don't. The lovers are bearded, tshirt wearing, beer loving, slightly troll-like, climbers and nerds. Not a bad demographic, but I fear that they have low standards. Mediocre food. Board games are fun. Very friendly staff. Great beer!

I might move to Boulder, just for this pub. Though it's rather small, it's still welcoming and I was lucky enough to stumble in on one of the last Stout Month nights. Holy hops- damn good beer. Damn good food - fish and chips 5 stars. Chicken quesadilla 5 stars. Even their CURRY (wtf?!) was great. Their fries are addicting, and all the pints are generous and cheap. I could live here. I just might. Be warned - all you weenies that can't handle a loud pub, don't ruin my night coming in here! It's elbow to elbow, loud, and every one is happy - NOT like a CA place. Spread the love, pass the beer.

My wife and I were on vacation in Denver and decided to take a trip up to Boulder. I saw this brew pub had a great review on yelp and we decided to pop in. The place was packed, and it offered samples of their new summer brew if you wanted. We were seated quickly and I ordered an FYIPA to start off with. It took awhile to get there, but I was pleasantly surprised with citrusy happiness. The menu was pretty extensive and pretty organic. Kind of a college hippie, all natural place. I ordered the tempeh rueben beer baked tempeh with sauerkraut, melted Swiss, tomato, vegan 1000 island on rye bread with chips, I substituted a side salad for like two buck for the chips. Love when I can sub a salad! Tempeh is a soy based product, but more in a loaf form than tofu. It was plenty tasty though! Everything about it would be a vegetarians delight. I had the XXX pale ale that was on tap with my meal, which was also real good. Just above average. Overall, a fun place for dinner. Lots of families and college kids enjoying their supper. The prices were very reasonable, and I would definitely take someone visiting back here.

Had a Fantastic experience here the other day. Was visiting Boulder from out of town (Iowa), and had been here one time previous a couple years earlier. To make a long story short, I'll break it down by bullet points. -Had about a 10 minute wait to be seated, was given free french fries while waiting. -Great selection of craft beer, waiter bought us first round since we were both from Iowa -Food took about 25 minutes (which was completely acceptable to me and my friends considering how busy they were that day) - Manager determined food had taken too long, gave us 50% off our bill (we assured her that the initial free beers were more than enough to make up for a slightly above average wait time, but she insisted) - Maybe the best burger I've ever had (Date night burger) - Manager came back later and told us that she had thought about it was going to take care of our entire meal (100% comp). We were shocked. I had never seen anything like it. We told her again and again that it really was not a big deal at all, but they insisted on not letting us pay for some of the best food I have eaten in a long time. HIGHLY RECOMMEND to anyone who likes great food good and equally delicious craft beer, with an amazing staff who prides themselves on A+ service. I will be returning to Boulder just to visit this place, if nothing else. BLOWN AWAY

We had to wait nearly 30 minutes to get in to eat here and when we did i was less than pleased with the ambiance. it's a cross between a college dorm cafeteria and my great aunt's kitchen. i ordered the daily special sandwich that I REALLY didn't care for. it was essentially inedible. it had beets and goat cheese, but basically tasted like goat cheese smeared on white bread. It was dry and not at all seasoned well. I took one bite. Not only did the waitress not take it off my bill, but she never came back in time for me to order something else. I had to scrounge off everyone else's scraps. Ew. F.

Pretty good place! I had the grilled cheese and tomato bisque with the raspberry wheat beer and it was pretty good! The SO got the Rueben but didn't understand it was a tempeh Ruben aka soy product so he wasn't a fan. Overall good atmosphere and good food. Decent prices too!
(5)
Liz S.

I wasn't impressed with this place. Sure, the waitress didn't charge me for tasting all of their beers while trying to find one I wanted to drink with my meal, but I had to taste all of their beers while trying to find one I wanted to drink with my meal! Mediocre beer at best. Burger was tiny. Fries were oily. Good thing we brought cash.

If you are looking for mouthwatering food to go with your craft beer go to Mountain Sun. The #1 IPA (I think IPA, some sort of ale) is a must try. Flowery, slightly citrusy, and crisp it is everything I look for in an ale. Dangerous drinking these because they go down so nicely and have a beefy ABV. I suggest getting a flight of beers and sampling as many as you can as the price is great. Friendly service from multiple servers. The whole staff seemed pretty stoked to be working there. We even got a beer on the house just because it was our first time there! Last thing, the food. Simple, cheap, and yet of the highest quality. Burritos are bomb here. Go treat yourself!

Loved our visit to Mountain Sun! You know you are in a good place when they give you free samples of beer and free fries while you wit for your table. All the servers were so friendly and they all worked well together. All the food was excellent too!

Super casual with great beer. The wait can be daunting but it's very kid-friendly with board games and consistently good food. I wavered between 3 and 4 stars because of the wait and inconsistent service but if you're looking for great beer and good food to pair with the beer, this is the place to go. Be sure to remember that they don't take credit cards which is inconvenient but keeps the prices reasonable.

Keira M.

Weird, but I liked it. I can best describe this place as a dive, diner, brew pub???? I would try it again.

Very reasonably priced for craft beer--just $5 for a pint. They're known for their stouts and they deliver. I ordered the our gang stout. It was made with ingredients from Australia. My friends got a java stout and a nitro oatmeal porter. We were all satisfied but all agreed I made the best choice. :)

The food is really not so good. The burgers are frozen patties and best and the famous fries were quite soggy. The service was ok and the beer, was what was expected for an IPA.

Casey H.

Damn it Yelp! You got us again! My boyfriend is a beer snob. So based on all of the yelpers raving about the porter and stuff. I dragged him to this place. It was totally not worth the hour wait. And no, the free taste of beer does not help. (The hostess will ask you if giving you a free tasting of beer will help make the wait more bearable.) Food - I had the fish tacos, the fish was breaded and served on a hard corn taco shell. I didn't like it at all. My boyfriend had the burger and fries. The fries were soggy and the patty was tasteless. Beer - "meh, it was okay" Service - The waiter took our order and since it was so busy, he didn't check on us or refilled our beverages.

Lucy C.

A friendly fun place. The service is always top notch. The food is delicious and they even have some great vegetarian options. The beer is crisp and they'll let you sample a few to decide. Can be crowded during peak times, but waiting at the bar is also a treat to chat with the servers. After a long day of climbing the beer is a fabulous treat. Remember to bring cash because they don't accept credit cards.

Amber B.

This place makes me wish I could drink beer (I can't because I am allergic to gluten, not because I'm some kind of snob). Sadface. We went there for happy hour and every piece of food was delicious. The atmosphere is super cozy and the waitstaff were all very nice. Definitely a nice place for hanging out with friends.

Kristi T.

Everything was great!!!! The food, the beers, and the SERVICE was great! We went as a group of 8 that included 4 kids (8-14). I called ahead and they put us on the list because it was a large group. We arrived and upon going in, I have to admit I wasn't sure it would be a good option with the kids. It is not very big and a bit loud. But at this point we would have a wait anywhere. We waited about 20 minutes after arrival, which was no big deal. We walked around pearl st. Watching the street performers and they called my cell when our table was ready. After being seated, we could sample any of the beers we wanted before ordering. The kids got board games from the bookcase and stayed entertained. And despite the noise level we were all still able to talk to each other and it not feel overpowered. The server who greeted us when we sat down said they all work as a team and any of them can help us. That was evident! Every time something was brought to us a different person was involved with our main server always checking in! They were all super friendly, personable, provided great service And were kid-friendly!! The food was great! Everybody loved the fries, Which we ordered to tide us over. We all commented with an air of surprise - these are REALLY good! Burgers, buffalo chicken, quesadilla, and the daily special - the Jerusalem plate were all good!! There were also gluten free options. They take cash only but there are ATMs inside and nearby. We will be back the next time we are in Boulder!!

I've been resisting reviewing the Mountain Sun for as long as I've been on Yelp because I haven't been able to think of any words to describe this piece of heaven. I still haven't thought of any, so please excuse me, but I just couldn't stand to not say something. I moved to Boulder in 2005, back when I thought of myself as a beer snob because I drank Heineken and Corona. One of the first restaurants I attended was the Mountain Sun. Obviously the food and drinks were amazing, but you probably already know that. What blew my mind was what happened when the check came. My partner and I discovered that the place was cash only and we had none of it; nor did we have an ATM card or checkbook, only a Visa. I thought we would be stuck washing dishes or have to promise them our first born. Instead, when I informed our server, I was told "Oh don't worry about it, you can get us next time." Say what? Even if the food and beer weren't the best on the planet, I would have returned simply for their style of doing business. Since that day I have been to the Sun (including Southern, Under the, and Vine Street Pub) hundreds of times and have never been disappointed. I leave Boulder often, but whenever I come back (and I always come back) the first thing I do is head to Mountain Sun and order myself an FYIPA and either a burger or the relatively new Speakeasy Steak sandwich. Just typing that makes my pants get a little tight.

Stopped in based on some yelp reviews I read--looks like the best burger in Boulder. We walked into an hour wait, but the hostess was nice enough to take my cell number and call me when it was ready, which afforded me the time to walk down Pearl. A gentleman called me and very enthusiastically told me our table was ready about 35 minutes later, which set a very positive tone for the meal. My friend and I sat down, and noticed that they didn't accept credit cards. We got up to leave, and our waiter and another gentleman working there practically begged us to stay, offering the ATM in the restaurant, or, my favorite part, offering to send our bill home with us along with a self address stamped envelope so we could pay later. He even brought out the envelope to show us. Class act, for sure. Our waitress was incredibly friendly and professional. Sorry to say I don't remember her name, but she had dark curly hair and some sweet boots on. On my way in, I had seen a patron eating fries with some sort of green sauce. I asked her if she by chance knew what it was, and she advised probably the vegetarian green chile. I ordered some to go with my burger, the Junk burger. The place was jumping and our waitress was super busy, so another waitress (some blonde girl) brought our food. She was not friendly at all. I remarked that the green chile was not what I had seen, and she stated 'did you order it?', and then left after I replied yes, stunned. I never got the green sauce I was looking for and we all wondered at my table why that girl was in customer service.... The burger was really good, moist and done medium rare just as requested. Fries were good as well--gotta say I loved the part on the menu where they state if your fries aren't up to par, they will replace them. The waitress came by specifically to check on our fries, which was nice. I would go back...but if I got that waitress who gave us our food, I would either leave or ask to be reseated. Their customer service was so good other than her.

Seriously, this place is totally amazing and worth all the great reviews here. This is hand-down some of the best beer I've ever had in my life. Their food was pretty darn delicious as well. The first person to greet us came over to ask about our tastes in beer, then brought us four samples he thought we would enjoy. Since my partner and I have different tastes, it was like we got to sample 8 different beers. It was love at first drink for me with the Annapura Amber - this is by far the smoothest amber ale I've ever drank - and the Raspberry Wheat. My partner greatly enjoyed the Kolsch and the Chazz Cat Rye. I sampled the Java Porter, the Chocolate Stout, and the Brown Ale. These were all good well. We decided to split the avocado and cheese sandwich to have something to snack on. Holy cow, this sandwich was amazing! The avocado tasted really fresh and I loved the flavor combinations. I highly recommend this place if you're in the area.

Billy R.

Where the locals go for pub food and fantastic micro brews. I've been eating (and drinking!) here regularly for years. I don't think I can recommend any other restaurant more highly if you're looking for an authentic Boulder experience and don't need the exorbitant prices or the pomp, but still want great food and beer. The only negative thing I can say is it is almost always packed because they're so awesome.

Jan I.

On the way back from hiking to Emerald Lake in the Rocky Mountain Nat'l Park, my son suggested we stop here -- it was 3 PM and we had to wait 10-15 minutes. It was packed. The hostess suggested we wait at the bar and have some free (free?) micro-brew beer tastings. What a great variety. They brew them all either at this location or at their Denver locations. The menu was typical bar food, but my quesadilla was stuffed with veggies and very tasty. My husband loved his burger. We didn't realize it was cash only, but it wasn't a problem.
(5)
Courtney B.

Long wait, but the burger I got was worth it! It had a fig jam and chilies on it and I got it on gluten free bread. So damn yummy! Hubby enjoyed his meal too. The service was decent once we were seated and things moved along OK from the kitchen. NOTE: this place is CASH ONLY and they conveniently have an ATM inside if you feel like getting raped in fees. :)

This place could easily charge double or triple there prices and it would still be well worth it. Great vibe and the outdoor patio is perfect for people watching on Pearl St!

Great beers, decent bar food. The catch is that they refuse to take credit cards and charge a fee on the atm that they make you use to pay them. The waiters also always refuse to split up the bill because 'it's too difficult'.

This was our first stop in Boulder and a memorable one at that. Awesome vibes and service. So damn peaceful. Great microbrewed craft beer - those stouts are nuts. At one point in the meal I just leaned back, took a look around and said something to the effect of "so this is Boulder, eh?" Felt like I had arrived. Part of me wishes I had never left.

Sassy Jackson was our server. He's like a 50's superman. He collects tea cup poodles and poses with them. He wears a scarlet begonia in his hair, because he's a huge grateful dead fan, but he only likes that song. Btdubbs, he's too sexy for his job.

Epic beer selection. I've been going here for years and I have never been disappointed. Consistent and great food is what you will find here. The portions are large and they nail it in terms of pub style food. Their IPA selection is diverse and interesting. They also always seem to have a good number of stouts and porters on tap too which I appreciate. At the bar they are very generous with sampling and bartenders have a plethora of beer knowledge. This is the place in Boulder to out and grab a beer. Mountain sun blows all other breweries in Boulder out of the water.

Marcus E.

First brew pub I visited in Boulder, cash only was interesting but they had a ATM so it wasn't an issue. Very unique community table "walk in" seating if your friendly enough to mingle with others. Staff is very friendly & willing to help, most likely because it's a tip share economy for the workers there, which is very nice for the customers. Awesome beers & a very good food menu for a little bar. I have been going here & to their sister restaurants since I moved to Colorado & there is a cool rumor they made their name grilling cheeses at Grateful Dead concerts. Not sure if this is true but would make sense after seeing all the different art & great live music they display for their customers. I live across the street from the southern sun & I believe both restaurants will do take out. So I normally call ahead, if they are busy I'll order food & then grab a beer at the bar there while they prepare it. They are normally very quick in the kitchen for such high volumes, tasty beer while you wait. both have outdoor seating, community tables, board games. NO TV's! :~) which is a good thing here

If you are not into the packed-house, loose your voice just talking to the person next to you thing; you might want to try the main brewery, Southern Sun. I like the Mountain sun for the amazing beer but it's rare to find a place to sit with a group of four. I dig their tempeh reuben and definitely try as many beers as you can. They are my favorite brewery as far as beer quality goes in Boulder, fo sho!

Melissa T.

I can't say much for the food, but as far as service goes - this place absolutely blew me away! My fiance and I stopped here for a couple beers yesterday after a full day of hiking around Boulder and because we were first timers our server comped TWO of our beers! Another server also came by with a free basket of fries for us to enjoy (they were delicious! but we didn't order any other food). They knew we were visiting from DC, and even though it's likely we won't be back in the area again for a long time they made it a point to take extra care of us. Clearly, they have enough business that they really didn't need to win over two more out-of-towners... so it definitely says a lot about their management and their time to treat us like that. Thanks Mountain Sun - we'll recommend you to all and definitely be back some day! :)

Beer sampler is awesome and we liked 5 of the 6 beers, which is rare for us as we are quite picky beer drinkers. Java Porter, raspberry wheat, Kolsch, white ale were all excellent. And the food, incredible food for the money! Great burger on wheat and wife had unbelievable vegan Reuben (how'd they do that!) We both loved out salads and left stunned at such an incredible price for the whole meal and beer sampling. Only downside is it can be a bit loud and crowded, but to be expected!

FANTASTIC! We travelled to Boulder from Ohio for a college visit. Our waitress gave us our first round of beers on the house as a welcome gift. And those beers were delicious. I ordered an IPA, my mom ordered a wheat beer. Their portion sizes were just what I'd expect for the price, but it wasn't so overwhelming that you couldn't walk around and enjoy Pearl Street after eating. I ordered a sandwich with mushrooms and various other vegetables. Honestly, I've never liked mayo in my entire life, but I decided to give theirs a shot (it's homemade) and I was so surprised! Nice and light, but a little bit tangy to counter the richness of the grilled veggies. This was the best meal I could have asked for after a stressful morning. The staff were just incredible and I felt so welcome. Our server was even just in her first round of training and she had such great control of her section. Can't wait to visit again!

Had dinner here last night. Very quick, friendly service. Had the raspberry wheat beer and it was outstanding! I had the winter chicken dinner. Shredded chicken cooked with thyme had a wonderful flavor, but the meat was a little dry. The Brussels sprouts, new potatoes and salad were very tasty. The place is very noisy and conversation can be difficult. They don't take credit cards. Very inexpensive. I look forward to going back next time I am in Boulder.

This place is an awesome local spot.

The atmosphere is loud and fun, and surprisingly appropriate for both college students and families! And I love stout month every February! I hope they consider adding another stout month to the year as I always find amazing new beers that I probably wouldn't have found otherwise.

From the exterior, it seemed like the perfect place to have a beer and hang out seeing everyone taking in the perfect afternoon. On the interior, it was smaller than I thought but much more like a restaurant than I expected. There is really not much of a bar at all, which is a little surprising to me. Nonetheless, I squeezed in and the bartenders were all very attentive and helpful! Unfortunately, I can't say I'm a big fan of their beers with one huge exception: King Crimson. I've never had an Imperial IRA but this one knocked it out. It's worth the visit just for this. I didn't get a chance to eat here but I'd like to get back here and sit outside and have a beer and grub sometime.

Just tried the beer sampler, not bad at all. It's weird that they don't accept any form of cards.... I thought this was 2014? I didn't have any of the food but it all smells delicious. I am still intrigued a lot by the whole mailed bill thing... whatever. Cool place though

The first time we passed this place my sister called it a Boulder institution, so I had to stop for a quick 8oz while the family shopped. I liked the first one a lot and might have stayed for another but the bar is really a counter with no stools so I decided to just come another time to try food. So Sunday night we arrived at 9:15 to find that the kitchen had closed and only late night stuff like chips and salsa was available. So we ate chips and tried several good beers, the most interesting one that I want to clone was a Java Porter. The real reason for the 3 stars vs four was the lousy service. They have an amazingly dumb system where no staff member has a title such as server, busboy, line chef, etc. and everyone rotates positions. As a server I can see why this is an attractive offer and makes work less boring, but in our case it also left me with the worst waitress in Boulder. We all know that waitering is not rocket science but practice does help and this chick must be a hell of a chef if she can be that bad of a server and keep a job. Ultimately my sister's use of the phrase "Boulder institution" seems accurate in that only here could you have a restaurant with lots of potential to be great but instead chooses to be crunchy and homey.

Great food and good beers... The best part is the service. The people who work here are amazing!!! Our server comped our first round since it was our first time in... He also chased out outside to give us our sunglasses that we left. All in all- great experience. We loved it!!!

Yummy food (is that a culinary term?). I opted for the eggplant Parmesan sliders just to try something different--I wasn't disappointed. The watermelon salad was a nice complement to the strong flavors on the sliders. Paired with the Annapurna Amber Ale, the entire lunch was enjoyable. The venue itself is a bit on the noisy side, but servers are accommodating.

Such great service and friendly wait staff! We were traveling through Boulder and only had a few hours to spare and Mountain Sun couldn't have been more welcoming! Lots of sampler beers and our first round on the house for being out of towners! Great atmosphere, would definitely go back.

We did some tastings while we waited for a table for lunch. Not the best beers I've ever had but good efforts and super friendly staff! Food was just eh for me, i got half&half the portobello sandwich was ok, had much better sandwich at murphys. The tomato bisque salty. I couldn't finish it My husbands fish and chips were to die for!! I was very jealous I didn't get them. The atmosphere was open, inviting, staff attentive and friendly. Wait not long.

Great place! The food is excellent as well as the beer. Is there really anything else to say? My only gripe is that they only accept local checks or cash.

Being vegetarian, I tried to find a veggie-friendly restaurant that would please both me and my carnivorous family. This restaurant fit the bill! I had the veggie burrito and the black bean burger, both incredibly delicious. They got one of the sides wrong, but they immediately apologized and removed it from the check! Amazing service, great food, and short wait-time.

We had such a great experience at Mountain Sun. Our young daughter was diagnosed with celiac a few months ago, and going out to eat can be a little stressful. She gets sick if she eats even a trace of gluten. We found Mountain Sun on a list of Boulder restaurants with gluten free menus. The hostess and our server could not have been more friendly and helpful. They immediately understood her restriction, and made several trips to the kitchen to make sure her meal was reliably gluten free. She had a burger with a gluten free bun and loved it. What we loved was the friendliness and helpfulness. We still feel self-conscious at restaurants with this new gluten free thing. The staff at Mountain Sun made us feel welcome, and they really went out of their way to ensure that we had a great dining experience. It meant a lot to a young girl who just wants to feel normal at a restaurant. It's worth the drive from Denver to Boulder to come back!

Popped in here for a burger and a brew while I was in Boulder. It's a lively friendly place at the start of the Pearl Street pedestrian area. The clientele run the gamut from students to crunchies to tourists so it's kind of a fun place to come in people watch. They are cash only so hit the ATM before coming in. The burgers are A-OK especially when washed down with a glass of Amber. I also love their spinach salad , a HUGE half salad was under $5 so that was a steal. The service is really friendly and everyone working there takes the time to make sure you're looked after and happy.

I ordered the Java Porter and was given the option of CO2 or Nitrogen to dispense my beer. That alone sets this place apart. The food too was excellent. I ordered the S.O.B. Burger and I would have to say that it ranks in the top three burgers I have eaten in Colorado. The staff was friendly, the environment was relaxed, and the price is reasonable; what more can you ask for?

I went here with a friend and had the date night burger. Best burger I've ever had! Totally worth the trip. Good service and reasonable prices

I stopped here one day to pick up some growler before an afternoon BBQ and realized they only take cash, which I never carry. So after realizing I only had enough to cover one of the two growers I ordered, the waitress gave me a Karma Envelope, which allowed me to send in a check for my whole order to send back when I got home. I loved this! Only in Boulder can you get a Karma Envelope to pay later. No name was taken and they just wrote the price inside the envelope. Their beer is pretty good, but their growlers are just giant Mason jars, which make for a difficult pour.

Christine R.

I f'ing love this place. No joke. Been here once, going back again. Tonight. First of all, the vibe, the friendly staff, the restaurant's philosophy - they all add to the experience. And the food. OMFG YUM. My bf ordered the Date burger = this thing is famous. In addition to my bf, two other people raved about this burger unsolicited. That is what greatness is. What really won us over, however, was when the waitress asked if our burgers were cooked to our desired temperature (med. rare), we kindly responded that it was a little overdone, but no worries - they were still delicious and we really weren't complaining. Next thing we know, our waitress comes back to let us know that they are covering our drinks for the burger not being done to our specs. WHO DOES THAT? This place does, that's who. Seriously, this place is a blast - board games, good beer, good food, GREAT STAFF. Can't really ask for much else. Oh yeah, and the prices are very reasonable. I may just move to Boulder and when I do - this place is going to be my second home.

After a hike in Boulder we were really wanting an amazing local place to eat and grab a drink. My friend found this place in lonely planet so we headed over. Right away we were impressed with the customer service and the food! Extremely friendly and funny. They work as a team and it feels more like a family! They went above and beyond any typical restaurant. I personally never write reviews on the Internet but had such an amazing exerience that we felt compelled to share! We refused to leave the table until this review was written! If you are in Boulder you HAVE to stop by for a drink and some amazing food!

This place was amazing! The staff was as nice as any place I've ever been. There was a bit of a wait when there on a Friday night, but we were offered free beer when our time passed. We were seated 5 minutes later. The beer was excellent! Absolutely the best brewery we visited in CO! There really was a team mentality in the restaurant, every server who walked by offered to top off our water, asked us if we needed anything,etc. The food was amazing! The burger I had was out of this world. I can't wait to go again!

Been here many a time, drank many a beer. All brews on tap are their own with a good selection of everything from pale ales to porters to Belgians. Food is solid with huge props going to the dang jalapeÃ±o mayo dip for the French fries. Holy crap I wanna take a shower in it. The wait staff will be all over you, askin if you'd like ANOTHER beer or some MORE mayo dip and before you know it you're drunk and fat and starin at the hippie tapestries draping the walls and wondering why you haven't gone to a Phish concert or String Cheese Incident show in 10 years and how is Trey able to jam as hard as he does on that Languedoc 6-string for like eight hours at a time!! Man oh man. I forget to bring cash with me more often than not cause I'm super into technology and debit cards which is the one downside of this place: they only take cash. They do have this busted lookin ATM in the back but it only reads my card 50% of the time especially when all I want is another dang Annapurna Ale!! Overall the majority of their beers hit the sweet spot, the food will fill your gullet nicely (with daily rotating specials), and the wait staff will take care of you. They do not disappoint. I know the quality I'm getting when I go here and I always leave satisfied.

I arrived during the dinner rush. During the summer, it's hard to get a seat, but usually I don't have a problem in the winter. The wait list was short, and it gave me an opportunity to try a few beer tasters at the bar. I ended up getting a Cat Burglar, which was being poured as my table was called. It came in a snifter, which is always a good sign. It was high in alcohol content, but that's okay, because it tasted great. While waiting for my friends to arrive, I got some french fries to munch on. I didn't get the cheese on them, but they were delicious anyways. I can only imagine how good they would be if I had decided on the cheese. Mmmm. I was working on my second Cat Burglar when my friends arrived. I had already decided on the pulled pork burger. It was one of their daily specials, which means it probably won't be on the menu anymore. However, their daily specials are always good and I highly recommend all of them. The pulled pork burger was no exception. My friends and I stayed and talked over another beer before heading home.

On a group lunch with other co-workers. The ordering process was clean,simple and efficient. The order time was good and the meal was satisfactory. I find its lack of accepting credit cards a little odd and out of place, especially in this modern digital age. But Boulder is an eclectic town with its own special unique charm.

Come for the beer. Stay for more beer. Hands down this was my favorite place in Colorado for eating and drinking. I had a great meal that consisted of a juicy burger and fries. They probably have the best fries in the history of fries. However, their delicious food was overshadowed by there amazing beer. I drank the XXX Pale Ale, which will is one of the best beers ever brewed. They were also very generous with the beer samples. Whenever my travels lead me back to Colorado, Mountain Sun will be my first stop. They have a neat decor that reminded me of a really nice head shop. The service is sometimes confusing because it seems like everybody there is your waiter. So you're constantly looking for your waiter/waitress, but you apparently can get service from everyone. Once again I'll say that there beer is amazing. If you love beer this is definitely the spot for you. I wish that they would open up a Mountain Sun in Chicago. If they did I probably could single handily keep that place in business. I hope Mountain Sun reads this and opens a location in my city. If not, I'll just buy a one-way ticket.

Sure, the burgers are good and service is pretty nice, but they don't take credit cards. If this was reflected in their pricing it would be one thing, but it's not. The diner charging $5 for a burger doesn't take credit cards (understandably); the bar charging $3 for a micro brew doesn't take credit cards (understandably); but a restaurant at this price point? Pretty much inexcusable. Most folk just don't walk around with wads of cash in 2014, and some folk never use an ATM.

Decided to visit Boulder and found that this was a high rated place so stopped by. Simply INCREDIBLE customer service. Everyone from the bar to waiters to the bussers were amazingly nice. Tried multiple samples of beers that were all delicious. Ordered the Raspberry Wheat in the end and a friend ordered the Colorado Kind Ale. Both were amazing! I was really impressed with all the employees and their knowledge of the drafts. The order of large fries is HUGE, definitely big enough to share between 4 or 5 people. The junk burgers were delicious. Shout out to Jon and Christine for some world class service. Definitely will recommend to friends and would visit again if I'm in Boulder!

Loved it! Beer was great, fries were great. We had the chicken quesadilla and the steak sandwich and they were both tasty. Service was great (we had Joshua!) even though they were packed on a Saturday night. Just note - they don't take cards! Cash only $$ so come prepared. They do have an ATM in the back, though, just in case you're a newbie.

Edit: The proprietor of Mountain Sun sent me an e-mail through yelp to apologize for the experience I had during my first visit to the pub. His email was so gracious, as was his email invitation to return, that I am inclined to think that my visit was just on an off-day, which can happen anywhere. I'm boosting my rating to A-OK for now and hope to update my review when I get a chance to return. --------------------------------------------------Â---------------------- Original review I don't get too upset when a restaurant makes mistakes; what does bother me, however, is when that restaurant puts the burden on the customer to fix the mistakes. I went to Mountain Sun for lunch recently. I ordered the half-sandwich/ soup combo. Apparently, the restaurant ran out of the soup I had ordered. Instead of letting me know BEFORE bringing my meal, the waitress brought out the soup I did not order with a casual, "Yeah, I just found out that we don't have the corn soup anymore. This is chicken noodle." After I gave her a blank look (because I don't like chicken noodle soup), she said, "Oh. Is that okay? Do you want it?" Not really, I said and asked if I could change my order to the salad (the other option for a half-sandwich combo). She said yes and then asked me to pick up the half sandwich from the plate and put it on a tiny butter plate in the meantime. I really didn't want to handle the sandwich right at the moment and make the messy move between plates, but whatever. After she left, I discovered that the avocado and cheese sandwich I ordered didn't have cheese. I found a server and told him about the mistake. "Oh. Uh. Do you want me to take this in the back and put some cheese in?" No, actually, I did not want what, a fourth person? handling the sandwich. I asked if he could make another. "Oh, uhh, okay, and I'll send the manager over." Maybe the woman who brought out my new sandwich was the manager, but I wouldn't know that since all she said was, "I just found out we were out of the soup of the day, too." After we had run out of things to mess up here, the order was still on our bill--most restaurants would have comped it. And the sandwich was kind of what the British would call "manky." I could have gotten a better one at Safeway. Way overrated.

All I wanted for dinner when I was in Boulder was a burger, and this place got the best reviews...So I tried it out. It was really busy on a Saturday evening, and I was dining alone, but they were kind enough to give me a table all to myself anyways. Good on them. I don't recall which burger I ordered, but they did a fine job cooking it to my medium rare specification. It was really a respectable burger, and accomplished exactly what I had in mind for it. The service was excellent; everybody working there was just the right amount of weird, and very friendly. This place definitely has a hip type of vibe to it. When it comes down to it, the food didn't blow me away, but exceeded what my expectations for a brewpub usually are. For that, it deserves a shot.

I have been here so many times and just realized I have never left them a review!! So, obviously I like this place, as I said, I come here often. First: Yes, they may get busy, so they may not be able to be shoved straight up your ass during the whole meal (who would want that anyway!?) but they are always so friendly, attentive, and just love to chat with you about local food, music, art, whatever. Plus (added bonus) everyone who is employed here is terribly good looking ;) Second: I have never gotten a burger here. I got the burrito once, and have never been able to switch off. Their vegetarian green chili is to die for, or they have one that has beef in it. That one is a red sauce and is pretty spicy, but also yummy. Also, I am big fan of their fries. I like to get cheese on mine. Third: The place is so cool and quirky. Cash only, but they will allow you to mail your check back to them!!! It is so weird, but they totally believe in humanity and karma, talk about a breath of fresh air! Also, if someone sends something back, or if something wasn't made right, instead of them throwing the food out, they will offer the food (as samples) to people sitting around the bar. They also always offer free samples of beer (and pretty much anything else). Fourth: Beer. Oh my, the beer. DELICIOUS. They have an amazing selection that is brewed in house and the selection will change seasonally. Also, moderately priced. We bring anyone visiting us from out of town here to sample the lovely beer, eat fresh, local food, and to see a restaurant that truly captures the essence and feel of Boulder!

Dare I say, I had the best burger I've had in Colorado here? Yes, I dare. Mountain Sun is so friggin hippielicious that I felt like I channeled the Grateful Dead just by sitting in there for an hour. We came here spontaneously on a Saturday afternoon with 15+ people and they were accommodating right off the bat. I couldn't have asked for better service and our server was giving us suggestions left and right on what to order food and drink wise. I've never been here before my visit this wknd but have been to Vine Street here in Denver and I felt like I was at the same place only a smaller location. Colors aside, a cool thing I love about Mountain Sun is that they let you sample beers until you "decide" on what beer you want. So, if you're ever looking for a place where you can explore different beers for free, Mountain Sun is the place! I tried a few IPA's until I decided on one that suited my taste and was in hoppy heaven with their FYIPA. In lieu of it being Cinco de Mayo, I chose to celebrate via food and ordered the Cinco de May burger. I've had some good burgers in my time in Colorado. Some have been mouthwatering, others more meh and these hippies make a mean burger. Simply put it-it was heaven in the form of a burger. Like anything good in life, it had a little bit of everything with a perfect balance: quality meat, cheese, PESTO (excited a little? Yes.) roasted peppers and squash. I wanted to moan at the table but didn't want to be a freak but it was definitely mouthgasm league. Kudos hippies and your burger and beer making abilities.

Howard W.

Great beer! Attentive waiter was nice and personable. I had the basil blue hamburger. It was good though it was still pinkish. This might bother some people. I ate all of it. When I finished it I realized I didn't remember tasting any of the blue cheese the menu described. The fries are not crispy. Cash only policy is bizarre in this day & age. Other reviewers are right: there is nothing to alert you to that payment policy until you see smallish print on the menu. This is a LOUD restaurant. I had to raise my voice the whole time to be heard. I would go again.

This is very trendy, normally not my scene but I needed to tell people how awesome the service is here. Best I've had in the states and I travel a lot. To the main bartender (maybe manager) he really knows how to set a scene and was amazing. Keep up the good work.

Charlie T.

I think most would flock to this place for the beer. I'm not a beer guy but can attest that the burgers are well above average. They were gracious to bring out some sample beers anyway and it was enjoyable to try them. The fries are a claim to fame and also very tasty. Quick warning: ranch dressing is an extra .50 cents but when you factor in the service it is no big deal. Honestly, the service at this place was just awesome. Each server was overly attentive and very kind. Would definitely go back and I encourage you to as well!

I have loved the sun since day one, almost 10 years ago. There used to be a sense of community and a desire to interact with local customers. It seems to me, since the expansion from 2 pubs to 5 they have lost their ability to give good service and appreciate those in the local community. I understand that capitalism is about the mighty dollar, but the sun used to be one of the quintessential boulder destinations. Now it is only a business that is concerned about money over community. I know that times change and so does the market. It would just be nice for someone to have 1 minute for a bar guest that doesn't want a table. The sun has some of the best beers In town, but since they can't keep up with production for 5 pubs with 3 breweries they can't keep their core beers on. I have always been impressed with the beer and it is the only thing that makes me return. The owners and the managers have accosted me at the bar based on my opinions of bands and my choice of clothing. I just want a friendly place to drink good beer that hasn't forgotten about the people that actually live in Boulder. Oh well I guess I can look forward to the day where their production is great enough to drink their beer at a place with better ambiance and service.

Service was good with a good attitude. They don't except credit card but if you don't pay they have something called a karma envelope and you can put the money in there to be mailed at a later time. What an original concept! If you don't know about they will let you try them. Centrally located on Pearl Street so it is a great place to grab a bite and walk around. Their raspberry beer was delicious flavorful and light.

Before you are shocked at my "only" 4 star review, know that I'm not really a beer drinker NOR do I eat much red meat. So, the two primary reasons you'd go here (beer and burgers) aren't things that interest me. Knowing this, four stars is actually pretty impressive! I did try the java porter and amber and both were excellent (5 star, ok?) for beer. My wife had a ginger beer and really liked it. Also, our server was awesome. 5 stars for him hands down. I had the pollo asado burrito - 3.5 stars. it was good and all, but nothing special. The kids shared a quesadilla which was your average quesadilla. We tried the fries because they were raved about by yelpers. They were 4 star. Good but not the best I've had. Also, get there early. I expected a big place and this place is pretty small for how popular it is If you're in Boulder, definitely worth a stop!

Whenever I have visitors from out of town, I take them to Mountain Sun. The food is just a step above pub grub, the beers are AMAZING (and a plentiful selection, too), and the staff are all a bunch of hipster-like sweethearts. Honestly, it's just such a good, down-to-earth pub and brewery that you can't go wrong. The only thing holding me back from giving it 5 stars is that it's super small for the crowd that is always there. Expect a 30 minute wait for dinnertime and to share a brew with new friends made at the bar while you're waiting.

I love this place! One of my favorite stand-bys when I want good service, a friendly atmosphere, and delicious food. Would definitely recommend it! Just a quick note about a complaint made earlier about being cash only--they do have a sign outside noting that this is their system, and it is written on their menus as a reminder too.

Although you can technically call this restaurant a "brewpub" by definition, what really defines this place is its flamboyant ode to nature and artistic expression. This place is far more than the purpose it serves as a business, or how it might be categorized in an internet search engine. One visit to this place and I knew it was special, unique and worthy of its own self-expressed definition. We arrived on a warm Saturday afternoon and business was busy as there tends to be a virtual parade of people on Pearl St during the summer. Mountain Sun, if you've read any reviews on the place, has garnered countless accolades by those that make this their food destination. As a brewery, they have covered an entire wall with medals earned in commercial brewing competitions. Clearly, they have been doing something right. We were told that there would be a brief 10 minute wait for a table, which is nothing to complain about on such a beautiful day. Eventually we were led to our table and I noticed that every table had something unique about it. There was custom artwork displayed in almost every observable space where one could imagine an artist finding enough room to move a paintbrush. It reminded me of Avogadro's Number in Ft. Collins, which is quite the spectacle in the same way. Visually, the restaurant engages the senses. I felt a sense of appreciation for those artists that took the time to share their artistic vision and made my experience more enjoyable. Our server was very impressive. In fact, the entire staff was terrific and I had no issues with any part of their service whatsoever. I was actually helped by several members of their staff and every one of them was seemed to genuinely care about our experience. We ordered samples of most of their beers on tap. All of which were tasty. The Colorado Kind Amber Ale was a more bitter version from others in the style, but quite good. We tried their trippel and saison which both had excellent esters and flavor balance. My favorite was their hybrid Belgian-American Pale Ale. This beer was the perfect choice for a summer afternoon with its refreshing blend of American hops and fruity Belgian yeast. The have a few versions of American IPAs, which were all subtly different in their bitterness and hop forward flavor profile but mostly about the same in alcohol content. I enjoyed those as well. Overall, they may not be on par with the more commercial production breweries in terms of quality, but for a brewpub I think they are excellent and worthy of their awarded recognition. The food was good, but not great. At the time they had a few special menu items. We had McMountain tacos and McMurray sandwich dishes. The tacos were seasoned well with a delicious combination of fresh ingredients, yet it was quite greasy (my plate was covered by the end of the meal with that coppery, shiny slime). My wife enjoyed the sandwich but didn't provide any criticism. I pecked at her Cajun seasoned fries and was disappointed due to the burnt charcoal like flavor that stood out more then the seasoning, not to mention they were fairly cold and quite limp and soggy. Overall, I give this place 4 stars, maybe 3 if I wasn't so impressed by their service and the general ambiance and dÃ©cor. I would definitely recommend this place!

$13.25 for a pitcher of beer? I love this state. Mountain Sun Pub was the first place I sat down and had a beer in Colorado - and I'm sure glad we did. The menu is simple - very easy going and reasonably priced. The beer selection is pretty incredible (and also very reasonably priced). Place was jumping on a Wednesday afternoon when we strolled on in. No problem getting a seat though and our waitress was attentive, but not annoying. I washed my beer down with a simple grilled cheese with bacon. Perfect start to an incredible week in that great state. Both sad and glad I didn't go to college in Boulder, because if I had I would have spent a lot of money in this place. I mean... they have board games!!!!

Went here hoping for some pub food and good beer and it met my expectations with flying colors. They asked if we had been there before and when we said no, the waiter asked what types of beers we liked and promptly brought over 4 samples to aid in our decision. It was a difficult decision since they were all really good, but I ended up with the Black IPA and my wife had the Raspberry Wheat. Then came time for the food. There were a number of burgers and other meals that sounded good. I got the special wrap for the day and my wife got a burger and chips. Burger was cooked medium well just like she ordered and the wrap was very tasty. I would definitely recommend Mountain Sun for when you're craving some pub food or just looking for a place to go have some really good beers. The one thing to be aware of is that it is cash only, which caught me off guard. Luckily I had some cash on me.

Mountain Sun is Boulder! You cannot visit one without the other. The staff is awesome, the vibe is friendly and comfortable, and the food is great. Not to mention they brew their own beer and have an amazing selection on tap. Mountain Sun has great specials every day, ranging from the daily hummus to an entree they change up daily. The standard menu is great and I've always felt the ingredients here are fresh.

The staff was excellent. They were both informative, professional, and accommodating. The food just was not that great. Disclaimer: I ordered out of my palette range of comfort. The atmosphere is so loud, but the artwork and feel of the place is great. May try again when in Boulder with something else on the menu. Update: I had a thoughtful response from the owner, and I am changing my rating to 4 stars from 3 stars. Again, this staff is excellent.

What a great place... Almost 20 house made brews, whth no fewer than six were porters/stouts when I visited (the selection rotates) ( am partial to dark beers). They offer 8oz pours for only USD 2.80, a great way to try several beers and not worry about driving. (Of course, they will let you have taste samples) 16oz glasses are only USD4.75. Food is very good, don;t miss the basil bleu cheese burger. Super friendly staff, too. A couple of oddities: No sit down bar (there is a small stand up one), so less easy to chat with other patrons. Would have given five stars if they did. Also, cash only.

This place is excellent. It's the kind of place where your waiter crouches down to talk to you and his name is Toyko and, for like two hours, you guys are (kinda) friends. They really know the beer they serve, and the beer -- most of the stuff I tried, at least -- is really excellent. In fact, I was ordering some beer for my sampler and my waiter was really nice and steered me toward some great brews. Love every IPA I tried there. I also had their signature steak sandwich, which was amazing and made from local, humanely treated cows. It was seriously strange how nice and helpful the staff here was, and it's always so pleasant when the food and the drinks and the service is equally great. Also, the place is very affordable, especially given Boulder standards. The one thing that made me pause when giving this place five stars was the pretty ridiculous no credit cards thing. This is 2014. Credit cards are the present and the future. It doesn't make much sense not to have them, and it's an inconvenience for the customer. I paid for my drinks and dinner with a check, which was definitely a lifetime first.

This was the best experience I've ever had at a brewery. I was in Boulder for a night visiting a friend after a work trip to Denver, and now that I'm back in NY I am having major Colorado beer withdrawal. The menu had an incredible list of beers that I've never seen before, which is great because I love trying new things. Even better, they give out free samples of all their varieties, no need to pay for flights to taste everything! I ended up with the Ciel Lumineux which was unlike any beer I've had before, fragrant almost like champagne, while my friend had a dark colored IPA that was also delicious. We were also given a brief tour of the brewery when I asked a question about the process. We were then informed that since it was our first time to the place, our drinks were on the house! Since we had to drive back, we unfortunately didn't get more, but I will make sure to stop by here if I ever come back. Everything about this experience was exceptional, and I wholeheartedly recommend this place

I'm not sure which I enjoyed more, the beer or the incredible service. The healing power of an FYIPA and a Date Night burger should not be underestimated. Restaurants like the Mountain Sun are a rare breed, and are always worth another visit.

Well this place is obviously awesome. A brewpub with tons of different kinds of beers (I had a very yummy IPA and a Rye-PA) and decent food (black bean soup, kinda bland, unfortunately) with the Williamsburg (i.e. Brooklyn) cast of characters? My friend and I ordered 3 beers and a cup of soup and it was 18, that's EIGHTEEN, dollars. That's insanely cheap for good craft beers. As my 4-stars say, Yay! I'm a fan.

Absolutely loved this place. Came here with a group of 10 and we all got our food and drinks quick and we were out of there in record time. I got the Java Porter and it might be my favorite beer I've ever tried. I was told it has caffeine in it as well, but it definitely didn't help with the food coma haha. The atmosphere is real hippie esque and casual. For my entree I got the Chicken asada burrito. I was expecting a chipotle sized burrito, but this huuuge sauce covered enchilda type burrito comes out. It was covered in a red hot sauce and really made the burrito taste amazing.. If you're torn between the burrito and something else.. get the burrito. Overall this place is exactly what you want in a casual sit down restaurant. The wait staff is incredibly helpful and nice and the food is amazing.

Stopped in here while brewery hopping around the area for a beer and some food. The food was awesome!!! Their nachos are maybe the best i have ever had!! All the food we had was great and they have a good beer selection. The decor was simple yet kinda cool, the staff was very good and it was a college crowd but, was wasn't filled with drunk retards. All in all it was a great experience and i cant wait to go back!!!

A great place to stumble into on a warm summers evening. I was strolling through Boulder for the first time in 30 years. I'm pretty sure I saw some of the same hippies from 30 years ago hanging out on Pearl St. I saw good reviews on Yelp for the Mountain Sun and got a random recommendation from the bike shop sales person..... good confirmation! It was busy but one of the waiters quickly greeted me, took my name for a table and offered me a beer. I told him what I like and he gave me a great recommendation for their Belgian Trippel. It was excellent. The beer was excellent. The menu has some really interesting pub grub. All of it with something unique. I chose the "Date Night Burger". It was served on a perfect roll with feta cheese and an incredible date puree. The hand cut fries were excellent. Great service, great beer, great food - that's a hat trick! Highly recommended.

Loved it all. I got the burrito in a bowl, which was plenty filling, cheap, and spicy. My friend's had some beers and burgers that they ranted and raved about also. The atmosphere was fun, and there were some quick community seating options if you're in a rush.

Ate their after ironman boulder. Beer is great and food is pretty good but our waitress jordyn (the Jordan who is blonde who likes to climb) is probably one of the nicest and most friendly waitresses I have ever met. I would not really go for the food but for loud fun atmosphere and jordyn being so friendly I would.

I've always had a certain affinity to Mountain Sun because it was the first restaurant I ever went to in Boulder and it was AWESOME. I've been back multiple times and have always had great beers and delicious food. The actual food is a little hippy at times, but it's definitely my style and I really enjoy it. I recently had a taster sample of their beers and was delighted by the plethora of different beers they serve. Be forewarned if you do order a sampler it is a set of 6 8oz pours... this definitely could be a bit daunting for the average boozer. The Raspberry Wheat is great starter for light drinkers, but the xxx IPA is a little more what I was looking for. My personal favorite is The Colorado Kind Ale this is a delicious beer that hits on all notes. I highly recommend anyone in the Boulder area to hit this place up. For the Denver peeps, The Vine Street Pub is close, but I still always rather go back to the original.

Poor environment. Been here twice and both times were lackluster. Loud, always too warm, don't accept CC, debit or mobile payments and we are in 2013. Staff is over stretched and non engaging. Food isn't good enough to have the ego they have.

11am meeting @ the Cup, 12pm meeting @ Mtn Sun = a good day in Boulder. I have liked MS forever. Good food, good beer & good service. Jalapeno burger and Java Porter Nitro = a good lunch.

Great outdoor counter seating for people watching. Food was delicious! Our party of three each got different entrees and were very pleased with everything. Update: 4/21/13 The food again was delicious but each time we come, I leave more and more disappointed in the service. The restaurant seems unorganized, servers are all over the place, no order. Today, after sitting down our waitress introduced herself the told us she would be bring water by since she couldn't take our drink order then. She soon returned to take drink orders, water never came. When she returned with our ordered drinks, we were told that our food order couldn't be taken because she would be yelled at for taking two orders together. 5 minutes later, she was ready to take our order. After getting our food we did not see our waitress again until we flagged her down (after a number of unsuccessful attempts) for drink refills. Not a big deal if it had not been 10 minutes without a drink eating a spicy meal. I did however notice that she had an opportunity to serve HERSELF a taster beer from the wall of taps. Glad someone's thirst was quenched at least. What a disappointment. Update: July 2013 Proprietor Kevin reached out to us via email and offered us the opportunity to be his guests to a complimentary dinner. Really appreciate how professional he was responding. unfortunately we haven't had a chance to take him up on his offer yet but plan to in the near future.

This place is phenomenal. The service and staff is some of the best I've ever experienced in my life. All of the staff seemed to love their work, and their performance reflected this. While we were waiting for our table, my friends and I just enjoyed watching the choreography of the waiters, bartenders, and busboys as they worked their tails off with smiles on their faces. The beer was excellent, with the Java Porter and the honey (ale) (i think it was an ale) were by far my favorites. I ordered a flight of 6 6oz samples, and they were all delicious. The food was pretty good, but after being so impressed by the staff and beer, I honestly wasn't even paying attention to the food...I would have had to get food poisoning to give this place only 4 stars.

Ryan W.

I've been to this place several times and have tried to convince myself that its worth the squeeze. Reasons I like it: Its a little cool, they have a decent selection of OK beers, and its easy for anyone to find something they can eat on the menu. Now, reasons I've come to dislike this place: They only take cash or check. Seriously? I see no reason for this other than tax fraud...or pure laziness. You're losing a lot of business by not accepting credit/debit cards. Get with the times. Second, this place is way too pretentious, especially SOME of their wait staff who seriously think they're the coolest people to walk the Earth. Finally, most of their servers don't know anything about the beer they're serving or how to even pronounce the names of the styles, not surprisingly. If you're going to work at a place that considers itself a brewery, you should probably know a good amount about beer. If not, please go back to your hippie tapestry filled apartment and smoke a bowl.

This has got to be one of my favorite places of all time. I almost didn't walk in because they didn't have a traditional bar area. You stand in front of the taps where all employees, cooks, cashier, wait staff, bartender, and bus people are busily working in front and around you. If you read their story, everyone does every job at the establishment. They are all friendly and work as an amazingly cohesive team, which also provides wonderful service! One staff member saw me taking a pic of the taps and told me to go behind the bar and pull my own beer and he'd take a picture. Awesome! Their beer....PHENOMENAL! The Jah Mon Ginger was amazingly refreshing and flavorful. Their Nitro Java Stout was another favorite. I tried almost all of them and I never encountered liking every single beer I tried at any microbrewery! We left to go walk around Pearl street but came back because we couldn't stay away. I'm in love with Mountain Sun. I want to marry it.

Holy hamburger goodness!!! As everyoene can make a decent burger slap cheese on it but if you are looking for a unique experience in a burger with unique tastes this is the place. So even with all of the reviews even with the hype this place did not dissapoint. First off if not from the Boulder area this is CASH ONLY, ATM in the back of restaurant. Secondly the parking is a little difficult as on Pearl St. and gets busy. As others have mentioned get there early as this place will fill up just to allow for extra time. As to the food...amazing. Started out with the French onion soup for appetizer as was hungry and didn't want to get nachos or fries. It was good nothing absolutely amazing but quality. Then with dinner I ordered a Oatmeal stout that was perfect exactly what I was expecting. Now as to the best part the burgers - I got the Date Night burger and my girl got a special burger with pears arrugala and basalmic reduction. They were both absoultely delicious. My date night was such a unique burger with goat cheese and date spread with bacon and jalapenos - I mean if that doesn't get you going then you need to check your pulse! Highly suggest this place. Also live music on Sunday nights starting at 10 pm.

BEST SERVICE. This place is super cute. Came here with a large group of friends under advisement of a co-worker. The food was really delicious, pretty much all the beer was great except for the one I ordered (champagne lady or something I don't know it was too sweet and was not really beer-like), but most of all the server was so so so helpful. He answered all my annoying questions with enthusiasm and honesty, he split the check without hesitation and made sure everyone was happy at all times without being hover-y. The portabello sandwich is fantastic and I can't wait to try their wraps and amazing sounding grilled cheeses.

Mountain Sun has a great "Boulder" atmosphere, with goofy tapestries on the walls, carpeted floors, and big wooden chairs and tables. The beer is amazing (with an amazingly high abv usually!) and while you wait for a table they often bring around samples of their delicious quesadilla. My favorite meun item: the basil blue burger. It's to die for. I always order a side of basil blue sauce to dip my fries in. Their quesadilla is also great, they have a good vegetarian ruben, and good chili. I am pretty sure everything on the meun is good. Only drawbacks: it's LOUD. Be prepared to loose your voice if you actually want to talk to the person you're with. They don't accept credit cards. They have an atm in the back that only costs $1 to draw from, so its not so bad, but it still can be a pain.

Daniel P.

This review is based upon ~25 visits, hopefully it presents a good cross section. Things you have to know: 1) They are ALWAYS BUSY, so plan accordingly 2) They do not accept cash, but there is an ATM in the back 3) Almost always extremely loud! (Most consider this a plus for atmosphere, but don't bring a date you are trying to get to know if you expect to be able to converse with them) 4) The Mountain Sun and Southern Sun have their specific, Mountain Sun way of doing things, and if you come in expecting a restaurant experience like any of the other restaurants in town, it is not that. It is its own scene and that is one of the things that makes it good, if not different. The Food: I will start with the food because it is my favorite part of this place. The spicy pollo asada burrito is my favorite, I get it "x-mas style" (red and green chili). It is always excellent, I usually fail to show up in time to account for the wait, so sometimes cannot wait the 30-60 minutes required to get a table during busy times. However, if you are willing to wait for the food, it is definitely worth it. The burgers are excellent, as is the chicken quesedilla, and the specials are always worth looking at as well. Everything is also very well priced for the amount of food you get, and the quality is great. Don't ever expect to walk in and be seated right away though, so if you are especially hungry show up early enough to get in, or try another time. The Beer: They have a constant rotating selection of beer, so the variety is a plus in and of itself. Some beers are definitely better then others, its a saying among Mountain Sun employees "friends don't let friends drink Colorado Kind" (so, might want to not). I would say if you are a beer lover you should definitely try the FY-IPA, Java Porter, and Drop Kick Irish Stout (on Nitro if its available). They also have excellent guest brews on tap, if there is anything by Russian River jump on it. The staff is extremely helpful when it comes to explaining beer, and will always give you a taste of anything you ask for, and an educated explanation. The scene at the bar can get a little bit crazy on busy nights, so if you are trying to yell at someone to order its try and identify what you want before you have to shout across 5 rows of people to order. The fact they brew so many of their own beers is awesome in my opinion though, and their beers compete with any of the best microbrewries in both Boulder and Fort Collins (such as Avery and Odell). The Servce: As addressed above, very friendly and helpful. Often they are super busy, but this is understandable, and hopefully something that you should already know before you walk in and expect dedicated, devoted service. The management does a great job of identifying good employees though, and even though I usually always see a few new faces, each of them provides the level of service I have come to associate with the Mountain Sun. One slight con, they have "seat yourself" policy, and I walked in with some friends who have not been before, and requested a specific server, Brian, who is excellent. The AGM Chris (who called himself the general manager, which is in fact not true), told me when I asked to be seated with Brian, "No, you can't do that, because we have SECTIONS". He did not offer to let us move, even though it was one of the incredibly rare not busy times, or offer an explanation of how to get a specific server in the future. However, as I mentioned in the start of this review, I have been to the Mountain Sun tons of times, and this is the only thing close to a service Snafu I have experienced, so it does not detract from my rating. Overall: 4 stars due to excellent beer variety, great food, and a cool atmosphere. Minus 1 star because it is too crowded to get in when you have a craving for their excellent food, and sometimes you just get tired of hearing "BEER, Who needs a beeeeeeeeeerr!" Absolute must try if you are new to Boulder though, and I definitely recommend it to anyone.

First visit to this mountain city, came to Mountain Sun based on reviews. I have to say they went way beyond my expectations. My friend and I split a burger, bacon & bleu to be exact, hand cut fries were a nice touch to my beer consumption. Our waitress was very helpful in our beer selections, also giving us samples of various beers served there. Which free beer is always nice, the communal tables kinda wierded me out also, however we found a two-seater so it wasn't so bad. There beer selection consists of the usual spread, light pilsners to a hearty stout. They did have a ginger beer that had a smooth mellowness when paired with the blackberry beer. Didn't try the IPA, even though it was a top seller. Also, it was the first time I had "Nitro-beer." Couldn't really tell the difference, perhaps I haven't been here long enough to figure it out. If there was a downfall, it would be bring CASH or CHECK, luckily my friend had some green or I would have been scrubbing dishes to pay off my tab. Still PINTS UP for this establishment, good food, good beer, & great atmosphere.

While walking by yesterday I noticed they just added a patio!! Tasty micro brew you can't get any where, but Mnt Sun, Southern Sun & Vine street pub. The burgers are my favorite in Boulder. Beware though this place is cash only. There is an ATM in the back by the restrooms.

After touring many CO breweries, I was running out of new ones to try. I found Mountain Sun and thought I would try it out. I was skeptical at first, as it looked mostly like a restaurant, and less like a brewery. But we braved it out and went up to the bar to sample some of their brews and were pleasantly surprised. One of the bartenders was quite knowledgeable about their brews, and let us sample several of them before settling on the ones we liked best. I enjoyed the Cleveland Brown, Pater Brown and Smoke Screen Porter. Also tried the Annapurna Amber and FYIPA.... both very good. I would return to this place. They are affiliated with the Vine Street Pub in downtown (near City Park), so if you want to try their brews while in downtown, head there instead.... great burgers.

IF STARBUCKS MADE BEER It would taste like Mountain Sun's Java Porter. What a nice surprise! Beer brewed with coffee can all too often end up weak and timid with just a hint of coffee aroma. Not so with the Java Porter. This beer has bold, assertive coffee flavor, nice body, strong roasted notes, and a delicate hoppy finish at the end. Honorable mention: The milk stout is also a standout.

Allison M.

We first had burgers here after a long hike and the burgers were so good! I tried the date night burger--which I have gone back for twice now--and it was an amazing combo of flavors on a perfectly cooked medium burger. I do agree with other reviewers that the buns could be improved, they are a little too soft and flavorless. The specials always sound/look so good but I haven't managed to pull myself away from the burgers yet, maybe next time. I like their beer selection and the fact that you can get free samples; this is especially nice if there is a wait so you can try beers before you sit down to order. They have pretty good beers at decent prices as well. Oh and the service has been consistently good, they are all team players and seem genuinely friendly. Nice, casual place but be warned it is cash only (there is an ATM onsite) and there is usually a wait to sit (we've experienced 10-30 minute wait but the food comes out quickly.)

Love this place, Boulder casual with great food and beer. The entire staff was amazing and went out of their way to please. I was undecided on which beer to order, our waiter (Andrew) brought out 4 samples and was ready to bring out more (at no charge of course). The other nice part is that it is REASONABLE and unpretentious unlike some other Boulder eateries that are a bit, shall we say, full of themselves. I will definitely be going back!

Great beer, ok burgers and fries. The beer here is really good and if that was all I'd had, I'd probably return often, but I get hungry...and their burgers are...well, just OK. I've eaten 3 of their burgers and they are all solid good burgers, but not fantastic...and the fries, well they are fresh cut, but if you can't cook fresh cut fries and make em crispy and not limp as wilted lettuce, just buy the bagged ones. I know that's poor form, but really, who likes limp fries? Now the beer is really good and honestly almost makes this a 4 star place, but not quite.

Excellent service, and the staff here really know their beer. It was crowded when we arrived and while waiting for our table, one of the bartenders gave me a sampling of 4 of their beers, after questioning me extensively as to my tastes. He even drew a diagram so that I would remember which beer was which. Once at our table, service was prompt and friendly even though the place was uber crowded. I had the chicken burrito and it was delish. Really spicy and flavorful and great washed down with a local brew. Tons of options on the menu, which makes me want to go back and try them all!

Justin M.

This place feels different than a lot of restaurants you encounter. Just walking in the door, I got a different vibe. I want to say earthy, but also spacey, which is completely contradictory. Anyway... Their variety of beer is great. I love that they have a sampler you can order and they actually give you options as to what you want instead of saying "this is the sampler, take it or leave it." Another perk on the sampler is that the glasses are a decent size, you don't feel like you get 3 swigs and that's it. You get a nice feel for each beer and get enough drinks from the glass to determine what you really do and do not enjoy. The beers range from superlight and easy to superdark and roasty, so there's something for everyone. The food was a solid B. Everyone in my party enjoyed their meal. The menu seems to be bar food with an organic twist that makes the dish unique. The service setup here is a bit strange, where there's no single person as your waiter/waitress. I remember reading something on the menu about how the manager could be the cook today, a waiter tomorrow, a busboy the next day, and the manager the day after. It's a bit jarring at first, but in the end I liked it because I didn't feel like a jerk asking random waitpeople for something. They've also got loads of board games here that you can play while you wait or while you drink, which is an interesting touch that seemed pretty popular. I'm going to come here again, that's for sure. I think they have a few other locations that I'm going to check out as well (though from what I gather they're all pretty similar.)

This was our first stop on our Honeymoon of Colorado & Wyoming. We had gotten of the plane and driven from Denver, so we were starving. I had half an avocado & cheese sandwich and salad, nice and refreshing. My husband had a Colorado grass-fed beef burger, and a beer. The burger had big flavor. Beer was nice too. Service has a "team" atmosphere. The owner stopped by a few times and made some delivery.

This place is awesome. Delicious food and great service. We did have a small issue when our bill came out (we were charged for a beer we didn't order), but they apologized and fixed it without much trouble. We ordered the Boom Boom Sandwich with Mushroom soup and the Carne Chicken burrito, highly recommend both!

I have not been back to Boulder since I have been 21 so I can't review the beers, but I dream and drool about the food. The french fries with malt vinegar are so good - I don't usually enjoy mushy fries but these were delicious, especially since they were fresh. Soups and salads are good, and I dream about the avocado and cheese sandwich mostly. I cannot wait to go back.

If you want to go to a burger joint / micro brewery that is the essence of Boulder, CO, this is the place for you! It does smell a little funny (which, I've been informed, is due to all the patron-spilled alcohol)... but the beer and the burgers will wow you. This place is *packed* every night, so the service gets a little hectic sometimes and seating after 6pm will require a short wait on Thurs-Sat nights. It's well worth it though. My personal favorites, *Beer: Raspberry Wheat, *Burger: Basil Blue Cheeseburger Oh, and they have an "Express Lunch" menu if you want to do take-out during the week.

Josh N.

What is there left to say about Mtn Sun that hasn't been said? There's a reason you'll wait for a table for an hour- it's worth it! Service is consistently better than you would expect for a place that is reduced to standing-room-only EVERY night. The beer is incredible, and the food is above average. I recommend whatever is on the specials list- it's always amazing, and the reason it's the special is because it's always made from what they can get, fresh. It's definitely my go-to place when I ask myself where to go to dinner. Highly recommended.

A true gem of boulder, this little pub almost encompasses everything about boulder in one little building. Its a small little hippy pub that offers tons of home made craft beers, all of which i've had are amazing. They have a ton of unique beers and of course the standards (IPA, pale, amber, ect...). I probably wouldn't come here just for the bar though, because: The food is amazing. I usually get whatever's on special the day i go and haven't been disappointed. I mean its not super expensive french meals from the future, but it is probably the best bar food ever. I also like that most of the food here seems generally healthy. i believe all of the ingredients are organic if I'm not mistaken. The Staff here from what I've seen is super friendly and on top of things. The only thing that's a little wacky is this pub is CASH ONLY. I didn't realize this when i walked in and ordered and after i ate i found this out, But the staff was super accommodating for allowing me to get money for the meal. A trip to boulder wouldn't be complete without a stop in this eccentric pub.

While I'm not happy to stumble across a spot that is cash only AND serves beer, I still managed to bust out my math skills and make a $20 bill go a lot further than I thought it would for two people. First off, raspberry IPA? Check. And it was GOOD. Sweeter than many beers, but it was refreshing after a long day. Secondly, BIG PORTIONS. As in VERY big. My veggie sandwich was loaded with lettuce, tomatoes, avocado... Mmm. Incredibly tasty, and somehow it survived a day and still tasted fabulous for breakfast. Heaven on a plate. The boy got the pulled pork sandwich special and that was equally as delicious as my non-meat meal. The pork was tender, moist, flavorful... it didn't need the bbq sauce, which in the South is a Big Deal. If your pork doesn't need sauce, you know it's incredible. Even with the sauce it was amazing, and the fries were fresh, hot, and tasted good solo or also dipped in that saucy goodness. Our server was very friendly and sweet, even offering to split a pint three ways so we could share a smaller amount and stay within our budgets. Oh, and did I mention board games?! That's right. THEY HAVE BOARD GAMES. That's an automatic win in case you didn't know. Know that this place gets packed and specials can run out. In fact, my boy got the last plate of bbq pork (making it even more amazing that it was the last plate and still tasted so good). The cash only thing is a bit of a drag, but if you don't mind the service fees, there is an ATM on site you can use. Hands down this was my favorite meal out of all the places we went to in Boulder. I'm a bit sad to have left it behind, actually...

They make their own beer and offer it in sizes as small as eight ounces, awesome for lunch! Plus, friendly service, good food (including veggie options), board games to play at the table, and a great location right off the Pearl St. Mall, what's not to love?

Pluses: It's soooo good. Sooo good. Some of the best beer around for sure. I don't think a person has been born who wouldn't love the beer and the food here. It's really what's for dinner. Minuses: 1. It's small and full of the stereotypical Boulder crowd, and can sometimes be next to impossible to get a seat. 2. They don't take credit cards. I understand they don't want to pay however-much in service fees to the stupid credit card companies that we all hate but are never-the-less all obliged to serve, but it's just a pain in the ass to have to walk back to the seedy ATM in the back and pay service fees. Call me biased but I see that as kind of disrespectful to the customer. I mean, we're still using credit cards because seriously who carries cash now adays? Might as well not make the customer have to pay for the fees. But that's just my own jaded opinion. No matter the hastle, this is the one place I'm willing to sacrifice a little comfort for. However the negatives definitely inhibit me from making the transition from the occasional customer to the dirty hippie sitting in the corner reading the newspaper.

Mountain Sun has lots of vegetarian options and a lot of things can be made vegan. Our waiter was very friendly and ran down the entire menu with me and informed me as to what was (or could be made) vegan. I was in sandwich mode, so I opted for the hummus and veggie sandwich and had avocados added. The sandwich was huge, but it was so good that I ate the entire thing. I also noticed MS has vegan 1,000 island dressing, so I may just throw that on the sandwich too next time. There are definitely some options if your vegan, a lot more if you're vegetarian. Overall we had a good experience here and we'll definitely go back - be mindful that you'll likely have to wait during lunch or dinner, this place gets super packed!

Hmmm, I honestly thought it would be better. I'm willing to come back and give it another shot because all the food at the tables around me looked good. My daughter really liked her meal. I ordered a Cobb salad which probably wasn't the best choice. The lettuce leaves were whole, not chopped up or anything, which made it difficult to eat. The burgers and fries at other tables looked delicious. Their house-made root beer was very good. We split a piece of cake for dessert, but it was dry.

JP S.

The food was decent, and the beer options were satisfying, but the noise was unbearable. Conversation was close to impossible without yelling. We all left with headaches. After our meal, stepping out into the relative quiet of Pearl St was refreshing. I want to like this place, but until they do something about their acoustics, I won't be returning.

Sarah Y.

This was one of my favorite places on our trip through Colorado. Service was great and quick, even though it was really crowded (even though it was a Tuesday night.) We had to wait about 10 minutes for a table, so they gave us some free fries while we perused the beer menu. We got a sampler of six beers and while they were all good, the java porter was by far my favorite. I was happy there was a good selection of vegetarian food. We got the hummus of the day (green chili honey) which was amazing and completely different... but in a good way. Also got a grilled cheese with pesto, which was delicious. On top of the great food and beer, there are no tvs, so while it was pretty loud, it wasn't as obnoxious as any other bar I've been to. So, to sum up, 5+ stars for Mountain Sun.

Today I had an excellent Labor Day wrap for lunch! Tempeh, couscous, romaine lettuce and onion in a tortilla. Here are some reasons why I LOVE Mountain Sun: *Romaine lettuce in their side salad accompanied by fresh tomatoes, shredded carrot, cucumber, onion, green pepper, and the best balsamic vinegarette dressing EVER! *All the waitstaff stop by to help, so you're never waiting for 'your' server. *Amazing beer- today I had Jah-mon Ginger and whoa. It was amazing! (then again I love Ginger). *Consistently delicious food. *Although they don't accept credit cards, there is an ATM conveniently placed next to the restrooms which only charges a $1.00 ATM fee. *Beautiful artwork painted on the walls *Nice location near the pearl street mall *Reasonably priced beer!!

Awesome little place. Good beer. Get the f.y.i.p.a. or the Java porter. Great deal on flights. Only got nachos for food and they were good.

James V.

The best burgers in Boulder, fresh cut fries, lots of great beer made on site. What's not to love about Mountain Sun? Be warned, if you come here on a busy night there will be a long queue. The loud, loose atmosphere may put you off if you're looking for anything close to an intimate dinner. Come for lunch if you want to avoid the crowds. You can sample any or all of the beers to find something you like, and you can even have a look in the back to see where it's made. The Date Night Burger is amazing and something you are not likely to find anywhere else. It has a sweet nutty flavor from the dates and nice smoky spicy kick from the grilled poblano peppers. Perfect medium rare both times I have ordered it, really delicious. The fries are excellent, cut fresh and perfectly crispy. Another place I'll miss back in Vegas.

Tara D.

Service here is top notch. The servers go above and beyond to help you choose just the right beer. The selection is diverse. I'm not a beer connoisseur, so I need some help. I was given 5 suggestions and little samples of each one. Awesome. Also had the reuben sammy which did not disappoint! Fun, casual vibe with a bit of street side patio as well.

Hanneke F.

So friendly, excellent brew, very generous with samples and recommendations. Good people watching in the outdoor space. Went here after trying out their sister pub on Vine Street in Denver (where thy actually brew in-house, so you can take a growler of your favorite home!). Thank you for the delicious birthday beer, Mountain Sun!

Rainey N.

This is an updated review. Since my first post, Mountain Sun staff has made a much more convincing effort to help me find something to eat that won't make me sick (dairy allergy). Last visit, I enjoyed a custom sandwich with dairy-free bread... and it was tasty! Plus we got some free fries and free beer. The manager was very attentive and helpful. The beer is still delicious, and now I can say the food and service are pretty good too. I'll go back. ;)

Lindsay K.

Really, truly, amazing customer service. I cannot say more about the quality and friendliness of their managers. We had a snafu with our order the other night (we had to wait about 35 min, the kitchen lost our order) and our entire meal was given to us for free. None of us even complained about the wait. Also, epic burgers.

Binal M.

We were on our way home from a long hike@ Rocky Mountain . After reading the reviews we stopped by at this Pub. I loved the easy going hippy vibe with eclectic decorations. We were waiting on a table and they asked us to sample some Beers. The server was really information and surely knew his beers. They asked us to try couple of beer and absolutely didnt want us to settle for something we didn't like. Once we selected our beer he figured we are newbies and offered us free beers.. btw who does that? (shhh...). We were completely happy with our entree. I had a Chicken burritos with green chilli.. the green chilli was off the hook. We had 2 beers and 2 entrees+taxes for about $21.. totally worth it!! will do it again in a blink

Mountain Sun, for me, is the heart of Boulder. Perfect atmosphere (they've even got board games!) with lots of fun art, amazing beer (including 8 oz beers -- perfect for me), and of course, terrific food (try the Date Night burger!). They'll also let you try as many samples of beer as you can handle. Only down side: it gets really, really crowded, especially weekend nights.
(5)
Janette G.

Awesome! Awesome! Awesome!!!! What a great customer experience! Free beer tasting. Wonderful beer! We sat down to order and was studying the menu and it said "cash only". Oops. No cash. No problem... There's an ATM.... except my boyfriend couldn't remember his PIN. I was quite frustrated bec I remembered asking him whether I needed to bring cash. The waitress old us tongi ahead and order. She will send us home a "Karma envelop". Basically send a check when you get home. What?!!!! A place of business that does that should be commended! Did I mention that the beer was amazing?
(5)
Kate M.

Mountain Sun has been making the best burgers and beer in town for twenty years. Going into Mountain Sun feels like coming home. Relaxed atmosphere and unparalleled service. The waiters and waitresses are genuinely enthusiastic and attentive. The date night burger is what my dreams are made of: date puree, peppers, bacon, and goat cheese. The make the BEST fries in town. As for the beer, the variety of styles in incredible. Mountain Sun was one of the leaders of the craft beer movement. They know what they are doing. One of my top five restaurants in town. Yes, that's right, I would take it over Frasca any day,

Gotta love the combination of good beer, good food and a great location. Easy to get to from Pearl Street, Mountain Sun offers a great escape. Their menu changes regularly depending on what is fresh, and their specials are usually the best route to take. It can be crowded, so I would recommend getting there early to beat the rush, but Mountain Sun provides a great laid back atmosphere to meet and talk with some of the Boulder locals over a great brewed in-house beer selection.
(5)
Alex P.

Took my parents here when they visited so they could get the true Boulder experience. They now affectionately refer to it as the "Happy Hippy Place." Often a long wait for a table but with the friendly staff and tasty brews, the wait is certainly beerable. With the communal service I felt I've never been neglected; also interesting to see the brew master cooking. That said, the food isn't at the peak of gastronomical sciences... it's simple and good.
(5)
Song S.

Everyone here is friendly and the place always seems to be bustling . There's a bar in the back in case you're waiting for a table or like us, you just want to stop in for a drink while walking around town. They'll let you taste what is on tap, which is great for the indecisive. But the bar is pretty tiny, watch your elbows.
(4)
Rick C.

They don't take credit cards .... odd? The beers were good but not outstanding. Wait staff very attentive and knew how to describe the various beers they produced. Old building = nice ambiance. Also, a nice place to watch people both inside the facility and walking by on the side-walk.

Finally, a Boulder restaurant that actually exceeds it's appearance (which admittedly is not hard to do in this particular case). Thought we were in trouble at first since in order to get a table you need to go to the busy bar area in the back and give your name to one of several servers in the hopes that you'll actually get one. Surprisingly this chaotic arrangement worked well as we were seated reasonably quickly and in order as far as I could tell. As an added bonus the servers would periodically come through with samples of their appetizers. As one should expect the beer is the real reason for coming here and it does not disappoint. Seriously this is some of the best beer in Colorado which is not a compliment I dole out lightly. Food was pretty much the standard pub fare you would expect with some Boulder flair. Service was good too. Servers were genuinely nice, not the hipster d-bag variety that could easily infiltrate an establishment like this. I will admit being "cash only" is a bit inconvenient and they could use a proper bar; however, these two minor knocks are not enough to take away a whole star. While I am aware this is not exactly fine dining Mountain Sun executes the brewpub blueprint perfectly, phenomenal beer, more than adequate food, and a genuinely cool atmosphere.

Great place! My brother and I shortly after 5pm on a Saturday because I paid attention to some prior reviews that said this place fills up and unless you want to be standing room only, you better arrive fairly early. It was nearly full but the two of us were seated at a 4-top. This was great because some establishments won't seat two people at a 4-top, especially if seating is at a premium, so kudos to Mountain Sun for not being 4-top snobs! In spite of the fairly small space and large crowd, this place really does have a cool and laid back vibe. I told the waitress that this was our first time and that we REALLY LIKE BEER, but were unsure of what to order. I asked if we could have a tasting and suggested that she could bring us some of her favorites. Clearly this gal REALLY LIKES BEER too because she brought us 8 tastings. What I really liked, wast that she took the time to write down the name of each beer on coasters so that we could keep track of what we were tasting. I'm not so good with recalling the names (especially after several "tastes") so having them written down was incredibly helpful. I ordered the Date Night burger and OMG......oh so yummy! My brother ordered a bacon cheeseburger and enjoyed his as well. I like home style fries, but the only minor issue was that they were a tad limp and not crunchy which I prefer. I feel bad even bringing this up, but this is an overall review so I wanted to share the whole experience...the good and the limp! :) Their beer is stellar and the service outstanding. We didn't want to be rude to others who were waiting for a table but we were really enjoying the experience and didn't want to be rushed. Our waitress didn't make us feel rushed in the slightest so thank you for that. I will most definitely be back! After Mountain Sun, we were off to Avery....

popped in here with my family in tow while visiting family in boulder. we had two kids in tow (2 yr old and 6 yr old) that had been out and about at the farmer's market, so you know they were a little wound up and crazy. anyway, the service was great; attentive and accommodating. the food was what i'd expect from a pub, so i have no complaints there. for me, this sort of place is all about basic comfort food, good service, and a great pour. i was not disappointed the least. as for the beer, i'm a bit of a hop head. i found the "kind ale" to be excellent and the xxx pale ale to be good. i was actually really surprised at the porter. even as a hop head i would highly recommend their porter. great stuff. i'll definitely be back while i'm in town. maybe even check out one of their other spots. the beer got me, but their really nice service is what's going to get me to come back.

Eric W.

The burger fell apart while I was eating it, juices running down my hands, pieces of bun and lettuce and cheese cascading to the plate. Crispy fries accompanied these fallen morsels as a sort of burger & fries salad. The beer was dark and good. The waiter was a hippie who was having ... a really good time. The bill was like $20 for the two of us. When I manage to get back to Boulder, I'll be back here. No question.

Kristin G.

Great beer and great food. We went on a weeknight, so we didn't have to wait at all- but I could see this place getting packed on the weekends! Everyone was really friendly and attentive. Can't wait to come here again next time I'm in Boulder!

Sarah M.

I was on a search for a pint glass for my collection...My friend and I sat down in a booth only to be greeted by the worst smell of BO ever. The whole place smelt like it. Is this normal, or we lucky enough to go on the one day it permeated everything? We were going to stick it out so I could at least get a beer and a glass. I asked the server if they sold them, and apparently they only sell plain glasses, why would I want a plain glass? She kept rushing us to make a decision of what to drink, and kept repeating, do you just want water, can I just bring you water? Jeez, fine yes, we'll get water. We got up and left as soon as she walked away. Horrible service, horrible smell, and no pint glasses.

For what it is, a cash-only burger joint with microbrewery and hippies, ultra-friendly waitstaff and campy feel, Mountain Sun totally succeeds. As David Z. mentioned below, the fries are excellent - skin on medium cut non-crispy yet satisfyingly tasty with vinegar. Burgers are also great too. Some other items that are good on the menu are: quesadillas (with or without chicken) soups (whatever kind, they're all consistently good - NOT CHILI) chicken sandwiches and, of course, beer. I like the browns and the wheats are also good too.

wild place. so much fun. games. cool vibe. although, one time i did get food poisoning from the veggie burger... great group hang place. more the merrier. AMAZING deals. pitchers of great local beers for under $10 during happy hour. unheard of.

Good beer and reasonable prices. Not too many choices on the menu outside of the burgers, salads, and fries variety but perfect for apres-sports-activity meals. Fairly typical burgers and beer place but with more locals than tourists.

Eric H.

A SOLID place for some beer and grub! If you want some straightforward (and cheap) food and some great beer while in the neighborhood of the Pearl Street shopping mecca, this is your place. Specials on the weeknights (things like burger and beer for $7), and a 4pm- 6pm happy hour every day. The service is efficient (and communal): You need salsa? Flag down pretty much anyone that works there and they'll be happy to hook you up. Be sure to bring cash 'cause that's all they take; there is an ATM in the back; see it on your way to the brewing tanks (and bathrooms). Yeah, so give a beer sampler a try (they've got almost 20 beers brewed in-house on any given day), but I can personally vouch for the Thunderhead Stout and their imperial IPA (which I think is called I & IPA). And like some other folks said, they've got boardgames waiting in the wings, free for all to play; find an open table and spend an afternoon (after you rock some running/biking/skiing, of course)..

Bob T.

While in Denver, I took a day trip up to boulder to check out a few places. I stopped in this place, and if you like good beer, it's a must. 18 TAPS! The people working there were so nice and helpful. They what ask, what type of beers I normally liked, then proceeded to place 3 samples of what they felt I would enjoy. I probably sampled 8 or 9 beers. The 2 I finally ended up getting, and recommend, are the Retro Pale Ale and the Chocolate Thunder Stout (I think that's what it was called). If you're in Boulder, stop by, you will not be disappointed

Well, this is a little bit scary. I live just over a block from Mountain Sun now. That means that when I get home just after four in the afternoon, I have to make a choice between walking to Mountain Sun and having a couple of happy hour priced pints or going to the gym. Anyone care to hazard a guess about how many times I've made it to the gym in the last two weeks? In the imaginary perfect town in my mind, Mountain Sun occupies a prime location on Main Street. Fortunately, in my real life, Mountain Sun occupies a prime location on Pearl Street and I actually get to go there. So, good beer, good food, excellent service (why doesn't anyone else copy their everyone is in charge of every table in the place attitude?), and great atmosphere. Negatives? I'm stretching a bit here to come up with something. It can get a bit loud. But it's a bar, what are you expecting?
(5)
Jess M.

Want to take a peak into a spot where real Boulderites go for a good time? Check out Mountain Sun or its sister Southern Sun. It's a combo microbrewery and restaurant- sure to treat you to a good time!The vast variety of award winning micro brews will not disappoint, the atmosphere is loud and fun, you can bring board games to your table to entertain yourself (yay!), the servers are attentive, friendly and knowledgeable, the food is tasty and the prices are right!! Check out their specials (I loved taco night) and you will be in for an old fashion tasty deal!

Without a doubt-- the BEST BAR IN BOULDER. I've lived in town for over 5 years now, and there is no place like this. A perfect 10 in every category. Basically a Grateful Dead version of Cheers. The food is-- as far as pub-style cuisine goes-- top notch. I'd go as far as to say that the Cheddar Junk Burger is the best burger I've ever had in a restaurant (but make sure to have plenty of napkins on hand). The service is fast and friendly. The beer is unmatched-- The Colorado Kind is one of my 3 favorite beers in the world. Every Sunday night, they bring in great live music. If you go, ask for Pat, Kat, or Chris (or Danny, if he's still around)-- they're the best. One small anecdote: When I first turned 21, I knew this was where I wanted to have my first legal pint. So I went with my roommate, got to the bar, and ordered a beer. As the bartender was bringing it over to me, my friend mentioned that it was my 21st birthday that day, and that she was serving me my first legal beer. Immediately, she turned around and poured the beer out. She then proceeded to fill up about 10 tasting glasses. As I sampled their many beers, she asked me what I liked about each of them, and what I didn't like. When I was finished, she brought back five more, from which she narrowed down my personal tastes even more. After a few rounds of honing in, she proclaimed that she'd found the perfect beer for me. She returned to the taps, poured me an Annapurna Amber, and told me it was "on the house". Four years later, and it's still one of my favorite beers. Now THAT is how you serve a new customer. I cannot say enough about this bar.

K G.

Being from the Northwest, this place definitely had a McMenamin's vibe about it: with hippy decor and a similar menu. What they had that McMenamin's does not, was several gold medal winning beers. I really liked the Saison I tried. The wait staff were very friendly. The only downside was that the place was so popular that there was quite a wait for a table, so this place wouldn't work as a place to go grab a pint.

jazzy l.

Awesome microbrewery on Pearl Street. We got a long bench table to sit on for the 10 of us. We ordered nachos, fries, different sampling of there beer (they brew it in the back). It was great, laid back and chill.

kara g.

I love love love this place and come here regularly for awesome burgers and ohhhhhhh the beer...they are constantly switching up their selection of in-house brews and have a great selection of guest microbrews as well. Their blackberry wheat and FYIPA are my favorites but they make amazing stouts/porters as well and stout month (in february) is a must if you are a local! Their girl scout stout is the best stout I have ever had, or maybe the coconut cream, it's a toss up. As others have stated, their house beers are unfiltered which I think makes it that much more delicious but I know some people tend to dislike, so beware. There are plenty of filtered guest beers if you insist. I have always gotten good service here, and yes, if it is dinnertime especially on a weekend you are going to have to wait, but big deal - you're going to have to wait anywhere you go on pearl street on a weekend!!! get over it, I say, or make a reservation somewhere way nicer and more expensive. this is a cheapish burger/beer pub, after all, not frasca. there is a great selection of vegan and vegetarian options here as well. and yes, there are a lot of hippies! so if you don't like guys with beards or the smell of patchouli, be forewarned. they have a fun selection of board games to play while you wait for your food, and the best fries and burgers in boulder IMO. the servers are very friendly and helpful in my experience and this makes the crowded waiting area easier to deal with, I think, as in they are very accommodating and pleasant even when, say, you might be blocking the entrance to the bar while waiting for your beer. they also are good about circulating appetizers while you are waiting, and I have gotten more than one free beer here for various assorted reasons. overall, this is a very laid-back, chill place with great food and great beer, and it's not a place to go if you expect highbrow attitudes, and maybe even if you expect others to wear deoderant :) I will agree with others that this place is very quintessentially "boulder" and if you are down with that vibe, check it out. if you want to be asked "sparkling or still" and not have to wait for your table at all, go somewhere else. I actually live closer to southern sun and it is essentially the same, and often does not have as long as a wait as mountain sun, if you are really concerned about that.

Kelly T.

During my 10 years in Boulder, Mountain Sun was my hangout. The restaurant is small with a few bigger tables and some booths. There is nothing like the vibe you get after a day or skiing or whatever, then walking into Mountain Sun for some Kind Ales and a Grilled Cheese. It feels like everyone in the place probably did something damn cool that day as well. TIPS: be ready to wait and stand by the bar for a while until your table is ready, service is not great...but it's worth it.

Yolanda T.

My favorite place to eat and have a great microbrew in Boulder. Not everything on the menu is to die for, but it doesn't matter because burgers are so amazing!!! They have a wide selection of ales and a down to earth atmosphere. I sadly moved away from Boulder but I make sure I stop by at least twice every time I visit because once just simply isn't enough.

This place is a fun college town pub! It's a conscious organization that brews their own brews and offers free range and organically grown food. Their rasberry wheat ale was good, their guinness-like stout fair, their wine selection not so hot (sort of for the wine in a box crowd), and they didn't offer any pear cider (I hope they do some day...), but outside of those few things, the atmosphere was fun, friendly, and ready to rock out. I enjoyed Mountain Sun.

Oh, the Mountain Sun (Pub and Brewery). What a great place to enjoy the mountains and the sun. Oh, and the hippies. Obviously--you are still in Boulder--so their presence will be KNOWN. Not that I eat burgers, but I hear the burgers hear leave little to the imagination. And the beer--just plain spectacular! (though I don't drink beer either). BUT I know peeps that come for miles! You will leave the Mountain Sun with a smile. You wont leave for a while. BUT when you do....

Jessi B.

I really would have given them 5 stars, but when I ordered my pepper jack burger with "fries"....they gave me a burger with pepper jack and "rice." I'm not kidding. And I DO NOT have a funny sounding accent either. They put rice on my burger. A little airheaded, but once they fixed the burger, it was great, and so was the beers I copiously consumed after I ordered my rice burger.

A couple other things you should know: they do not accept credit cards and they have board-type games to play while you eat and hangout..

For the quality of the beer, food and for the low prices, this place is unbeatable for a pint, a (free range) burger and superb pub fries. Of course, it's hardly unpopular, so at peak hours there will be a wait (at the bar).

Some places just take you back to a time when life wasn't so chain-oriented and dining out experiences felt authentic. This is the ultimate grad student hang out in Boulder and the beer is arguably the best in the city. (I drink anything off of the nitro tap). Coming from Chicago, I had this gleeful moment of reverse sticker shock during happy hour....and the quality of the happy hour beers. The burgers are fine, but come here for the beer and hanging out aspect. Southern Sun is also great, and considerably larger...

Amazing!!! You are missing out if you do not stop at this place when you are in Boulder. This experience is for those looking for amazing beer (and I am a wine drinker, but the tripel and the porter made me a fan!) amazing service (let's just say this- the place is packed, the bar is full of tables waiting, but you quickly have beer tastings in your hand and free French fries while you wait and as soon as you are completely fine with tasting beer as long as needed (5 minutes) you are called to sit at your table. Wow! Fine tuning is what is happening with the staff here- they all are completely integrated and working on amazing customer service. As others have mentioned, take some cash, or hit up the ATM ($1.00- right outside), if you don't have either of those the "karma card" will get you a meal (you mail your payment for your food in a self-stamped envelope when you get home- right??? Amazing!! - love!!). Ok - lets just add that the cost of this food is almost unbelievable- very affordable. We had the junk burger, quesadilla, french fries (add the cheese, stop counting calories- worth it!), and a porter for dessert!

Mountain Sun encompasses everything granola and homeyish that I think of when I think of Boulder. The menu is eclectic, lots of sandwiches, salads, and burgers. And the beer menu was long, so long that they let you get free samples of beers of your choosing (aka free sample pregame). Our table ordered the nachos as an appetizer and a delicious pile of chips, cheese, and salsa was on our table in no time. If you don't want to see the person sitting across from you, order this nacho mountain. For dinner I chose the Monterey Chicken sandwich mainly because it had guac on it. It was good but nothing to rave about. I stole some fries from my friend mid-dinner and they were fantastic. Apparently her Date-Night burger with goat cheese was fantastic as well. I would definitely recommend Mountain Sun to anyone looking for a casual cheeseburger and beer type of dinner that won't break the bank.

Staff was exceptionally friendly and helpful. They make you feel like family. Great location for food, drinks and relaxation. Had a few of their microbrews and the Walnut Pear salad. Excellent!

Go Here. I have never felt so dang welcome in a place as much as I did at my time at Mountain Sun Pub & Brewery. Talk about amazing customer service. Before I get too far into details, the absolute coolest thing: Karma checks. WHAT? What is this do you ask? They are cash only and have an ATM on site that only charges $1 BUTTTT... If you don't have either, they want you to stay and enjoy yourself so they give you your bill along with a self addressed stamped envelope so you can mail your payment back to them. WHAT? Yo, how can you NOT appreciate this and realize this business wants to please? Loved that so much. We were immediately approached and told of all the amazingness of this spot and it wasn't even our server; they work in teams to make sure everyone is taken care of but you do have a main server. So our welcome was just to inform us of what they offer, the Karma checks, they even let you know that their fries are freshly cut so if they don't taste perfect, let them know and they will get you a perfect serving. Immediately got water and our drink order was taken. You can sample anything you would like. They had one cider so I went with that and it was refreshing and delicious. It was the Colorado Cider Company, Glider Cider. So light. They also offer pairing suggestions for their dishes. For their menus: "At the Mountain Sun Pubs, we prepare all our menu items from scratch everyday. We believe the most important part of being a community pub is bringing you the freshest ingredients we could find and preparing them in a healthy, hearty, down-to-earth style. We choose organic, chemical-free and genetically unaltered products when they are available." I feasted on the Junk BURGER with bacon, cheddar, sautÃ©ed mushrooms and onions with roasted garlic mayo. Cooked a perfect medium and so dang flavorful and juicy. The fresh fries were perfect as well. Such a great, filling lunch. Definitely check out one of their locations if you can! - Mountain Sun - Vine Street - Southern Sun - Long's Peak - Under The Sun

Busy even at 10PM on a weeknight! We stopped in here for a bite after catching some music at the Laughing Goat, and had to put a name on the waiting list. It's definitely a pub atmosphere -- dark, loud, and full of beer-lovers (ie, not really my scene). Neither of us drink, but the staff gave us samples of root beer. I wasn't terribly hungry and stuck with a grilled cheese sandwich with a side of their daily special "Asian" chicken soup. Service was nice enough, though I think three different people waited on us. Edit: The owner reached out to follow up on this review! I'm not sure we'll been in the area again anytime soon to give them another try, but the fact that he took the time to send a message really means a lot.

I sought out this brewery on a return trip to Boulder because it was that good. I also love the team atmosphere and karma envelopes (though I chose to walk to ATM first, the option restores my faith in humanity). Did I mention the beer is phenomenal and the food prices are almost too reasonable? Is this a trick? I guess it prompts one to tip better I had the veggie burger (standard puck, unfortunately) with blue cheese and basil sauce. I put that yummy goodness all over my fries and know for next time to order a side of it for dipping. How do I love thee, Mountain Sun? Let me count the ways: Mountain Sun on Pearl, Southern Sun and Under the Sun on Broadway near Eldorado Springs...that's 3 at least!

After writing my first review for this restaurant the owner actually sent me a message apologizing for everything and he stated that he has his staff currently working on rectifying the problems that we experienced, he then invited us to come back for a dinner on him. When we went back I got the chicken Quesadilla and my husband got the steak sandwich. I did order fries again to see if they were better and they were! I loved my quesadilla and the steak sandwich was great according to my husband. The fries actually had salt on them and they were crispier this time, which I prefer, some people may like softer fries. My husband absolutely loves their beer, so he wanted to let everyone know, so we got some to go as well. The service was great and they went out of their way to let us know that they cared about us and our opinion on the restaurant. We had a manager come to our table and apologize for our last visit and he made sure to check in on us while we were there. We had a new waitress who did very well, so I was much happier this time around. Maybe we caught them on an off day the first time, but I'm so glad the owner reached out to us, that is just excellent customer service and a good way of doing business! Try this place out!

There's something comforting about this place that I just can't quite put my finger on. I have so many fond memories of coming here with friends when I lived in Boulder. The food is delicious and the beer tastes amazing. It's a very warm, communal place and I consider it to be far more iconic to Boulder than the tourist-traps, of which this is not one.

The service and staff here is undoubtedly hard-working, friendly and COOL. Like...you wish you were their friends and had their haircut/leggings. Standing at the counter taste-testing beers, you can tell they work as a team to move the process along, get patrons seated and get their food and libations to them quickly. My man and I stopped in on a Sunday around 1pm and had to wait a little bit--It was a sunny Boulder day, so everyone wanted some crisp beer. My boyfriend ordered his fave beer there Alnapurna. We ordered the special of the day, the Seitan Wrap. Although I'm a vegetarian, Seitan weirds me out. And although they were going for the BBQ chicken Seitan feel, the flavor just needed a smidgen of an extra flavor boost/zing. The salad was fresh, and I love homemade dressings. But the showstopper was the Olive-Feta Hummus! SOOOOOOO DELISH. They give you SO much and it's hard to stop eating it. mm mmm mm

Good beer at a good location. No problems with the service, but the Black and Blue Burger was just ok, not that impressive. They also lost a star for being cash only, really? On Pearl St?.

Colorado Kind! Need I say more. Best handcut fries in Colorado. My last meal request would be a Junk Burger and Fries. Always a bit of a wait, but the service will knock you off your feet.

One of my friends and I have decided that over the next year, we are going to visit all of the breweries and brewpubs in Colorado. Apparently there are 152. Mostly we have been focusing on breweries, as this was the first brewpub to which we have gone. It's on the south end of Pearl Street mall, which means there is an eclectic crowd, and they employ a bunch of 20-something hippies. They have really nice, attentive service, though, so I am by no means insulting them. They have a very appealing menu, with lots of veggie options, but I went for a black and blue burger. It was a nice size- normal, not some monstrosity- with hand cut fries for $1 more. They were a little limp, but again, I am a fry snob. The burger was amazing, cooked perfectly, lots of blue cheese, nice roll and good, fresh looking veggies. We also got beer sampler, where you get 6 half pints for $10.50... really a good deal if you think about it. We got a blackberry wheat beer, which I will be craving when summer rolls around. They also have a java porter which tasted like an iced coffee. We had a few other beers, all really good but slipping my mind... I had a kind of boozy, rambunctious weekend.

For good bier and good pub food, this is the place to go. I have always had fabulous service and great food. I have never had a dish I did not like. the bier here is good quality. They have a wide variety for all bier drinkers around. The staff knows about the biers and will happily help you choose a beverage for you taste. The food is quality American style food, great sandwiches and burgers. The place does not accept credit cards but there is an ATM by the restrooms. They also have games for your enjoyment. It is a wonderful place to go for a group or just two people. Never had a bad experience at this wonderful pub.

Yoyo T.

This is right around the corner from my place, but I'd come here anyways because this place is delicious. If you're looking for a good beer, excellent food and games then this is the place to be. There's usually a wait of around 20 minutes, so don't expect to get seated right away. But grab a beer and the wait will be over quick. They have a huge selection of beers, with my favorite being the Java Porter. The food also comes out fairly quickly with huge portions of fries and burger. I've tried a few things on the menu with nothing ever disappointing me. The burgers are good, the burrito is big and the desserts are delicious. Oh so good. Ok...I have to stop writing before I get a pregnant woman's craving for this place tonight.

I'm 31 years old, and I've lived in Boulder for my entire life. I know food and restaurants around here. This is absolutely the best food, the best beer, the best prices, and the best service you can hope to find around town. There's usually a really long wait before you're seated (up to an hour), but it is absolutely worth it - especially because it means you get to drink more beer :) I recommend everything. Even the veggie entrees are amazing. Eat and drink in bliss!

I was in Boulder visiting a friend and after a long day of snow shoeing in the hills we needed a GOOD meal. And Mountain Sun did not disappoint! I ordered a cheeseburger with fries and their Blackberry wheat beer. My friends ordered the "Junk Burger" which was loaded with bacon, avocado and cheese, and a "Basil Burger" with this deletable basil and blue cheese puree sauce. The verdict at the end of our silent meal (as we were all too busy shoveling into our mouths) was... "mmmmmm.....tasty MEAT". It must be the beef on Colorado, but the burger was well made with fresh veggies (lettuce, tomato and red onions) and a basket of crispy fries (extra $1 as they give you tortilla chips as a standard). The feel of the restaurant was casual, homey, and fun. The servers were attentive and helpful. Ours even offered my friend a tasting of beers when they didn't have anything she wanted immediately. He brought 4 to her that he thought she would be into, and he was right on. So if you're in Boulder and coming back from a full day on the slopes and want a good burger with even tastier beers I recommend Mountain Sun to everyone.

This place is one of my faves in Boulder. It has amazing food and an amazing Bouldery atmosphere that's great for people watching. They also brew their own beer and have an awesome selection. If you like IPA try the FYIPA there. If you like less hoppy beer go for the Quin's or Bombshell Blonde. The burgers are really good there and the special is always super good too. You can make pretty much everything there vegetarian too if you want. The veggie patty they make is tasty. The service here is excellent too. 5 stars hands down.

Great place. Arrived on a Saturday at 11:00 am as they were opening. By noon they were packed. Our waitress could not have been better. Allowed multiple tastings. As many as we wanted. Eggplant sliders were EGGCELLENT! French fries great. Burrito was huge. We are so glad we stopped here on our visit through Boulder. Beat the crowd!!!

So we walked into Mountain Sun Pub & Brewery around 5:00 on a Saturday - the place was packed. It's located just east of Pearl Street Mall. There's this little sign that instructs us to go put our name in at the bar located at the back of the pub if we want to get a table. Given that the wait at the bar was three people deep, I was sure it would take forever to get someone's attention to get our name on a list, as it didn't appear that there was a host performing this specific task. Half way to the bar, I considered for a split second just turning around and going down the street to dine elsewhere. However, prior to our arrival at Mountain Sun, we were at a local brewery and asked for recommendations on a place in Boulder that served really good burgers. More than a couple of people chimed in and said this was the place to go. So I quickly rechanneled my energy into making it toward the bar. I'm so glad I did. With about 15 feet to go, a guy behind the bar made eye contact with me and waved me on to head his way. He introduced himself as Will, and asked for my name and then took our drink order. We ordered a couple of Mountain Sun's signature brews and stood at the bar, visiting with the people working behind the bar. This place was crazy busy, the people behind the bar working at a very fast pace, but they remained very attentive, happy to answer any questions, serve up a taster, and hand out free samples of beer. I was so impressed with the service, I left a tip on the bar equivalent to the price of our two brews. Will picked it up, thanked me and put the tip into a big pitcher sitting on the bar. After waiting at the bar for 30 minutes or so (the time flew) another guy came up to me and said that our table was ready. He introduced himself as Matt, walked us to our table, and told us that if we needed anything during our time there that we should just ask him. A young woman came to the table, introduced herself - Elizabeth - and asked if we had any questions about the menu. She told us to take our time in reviewing the menu and making a decision on our order. Our burgers arrived, cooked exactly as we ordered them. As we enjoyed our burgers, Will, Matt and Elizabeth all checked in with us at some point and asked if they could get us anything. I've only written about the service because it was so extraordinarily refreshing - happy, helpful, extremely attentive people working there - every single one of them! Then BF pointed out to me a short paragraph on the front of the menu and everything made sense: "Welcome to the Mountain Sun Pub & Brewery. We believe our approach to the service industry is unique and worth noticing. Your server today may be cooking your food tomorrow, or even managing. Each employee does every job here. Our 'team system' also means that we take initiative to bus each other's tables, run food, do dishes, help you to a beer at the bar, or put your name on the wait list. As a result of this team approach, when you leave a tip, your generosity is shared among various members of the team. So feel free to ask any of us how the food is prepared, your estimated wait time, or where to find Yahtzee." Oh yeah, the food - delicious! Grass-fed beef burger, juicy and grilled just the way I like it.. Fresh LTO and pickles to top the burger. The fresh cut fries were crispy on the outside, perfectly cooked on the inside. And my new favorite local brew - Nitro Kind - a smooth finish that is unique to nitrogen beers. I will definitely be visiting Mountain Sun again not only for the great food, but for the amazing overall experience.

This little Boulder hotspot not only serves great beer and food, but is a huge bang for the buck! At 2:20p.m. there was still 25 minute wait! Their beer taster is a great deal! My husband and I shared the Brewery Taster package which is $10 for SIX selections of 8 oz drinks! Helloooo cheap! As we prefer dark and strongly flavored beers (Guiness lovers), WHAT WE LIKED: -The Java Porter is excellent - my favorite at this microbrewery - with real coffee and balanced flavors with a kick. Has a creamy finish with kind of a barley hoppy finish. - Old School Stout reminds me of Guiiness with a slightly more chocolately flavor to it. - Annapurna Amber is like Killians Red - Smooth, medium bodied, basic and simple...very nice. WHAT WAS JUST OK: - Colorado Kind Ale - definitely a hoppy ale, refreshing but not my style. Has a kick with a strong flavor! EWWW: -The Jahmon Ginger was weird! Tasted like chinese cold soup that you drink when you're sick. -Hmm, although the FYIPA is their most popular beer apparently, i can''t comment on it cuz IPA makes me cringe -this was like over the top citrusy hoppy. In terms of food, I had the Avocado and cheese sandwich- this was a refreshing Veggie sandwich - they should probabaly add sauce to it though - could use a bit more flavor. The service is great and helpful too! By the way, it's CASH ONLY. I know, weird!

Mountain Sun for life! This is hands down, my favorite place in Boulder..solo, on a date, with a group, or entertaining out of town company. The beer is not only incredibly original, it is consistently GREAT. The menu is diverse and is very accommodating to dietary specifics (gluten free, vegan) which is a HUGE part of why I support them diligently. Absolutely anyone is welcome here, and the friendly vibe permeates everything. You can tell that the staff likes each other, and the customer service is seamless. It makes me happy to spend time here. Add board games ready to be played to the mix, and you have a pretty good afternoon/night in store. If for no other reason.. stop in for a pint of their FYIPA. Killer.

I don't know why I keep coming back to mountain sun every time I'm in Boulder but I just can't seem to stay away. Maybe it's the set of six 7 oz tasters that got me hooked (fave beer so far: XXX ipa), or perhaps it's the clean and not so greasy tasting pub fare. Or maybe it's because it reminds me of McMenamins in Portland (the menu layout and design look eerily similar). Or it might be that I find a place that doesn't accept credit cards in this day and age to be quite endearing. No matter what, I'll prolly keep comin'.

We had dinner there last night and it was great. If you are looking for a lively atmosphere with excellent beer and burgers this is the place. Any beer lover will find a few different ones to enjoy and the burgers my son and I had were the best. A hard act to follow for pub food. My wife had the steak sandwich and loved the taste, but thought there was too much bread for the amount of meat (that's why it's 4 stars and not 5). Great staff - very attentive, friendly & helpful. Provided free fries while we waited for our table. We'll visit it again next time we are in Boulder.

My favorite place on earth...they actually have a Phish poster on the wall and Grateful Dead stickers with tapestries all over. They were playing Phish off of someone's iPod. All I can say is this is Heaven on Earth. You just don't get places like this in DC area or most of the east coast. Maybe in the Carolina's or up in the north eastern parts but I have looked high and low and the closest thing to "hippie" in DC would have to be Lost Dog or maybe Grog and Tankard but that is a stretch of the imagination compared to Mountain Sun. I had the Kind Ale and the vegan Tempeh Reuben and it was awesome! I have made it at home once before but this was definitely better. Great crowd, great music, beer and food. If I only I could convince my husband to move to Boulder but I may have to settle for the occasional visit.

Great beer and great prices. The place loses a star because it only accepts cash and has a cash machine in house which charges $1. I find this slightly obnoxious. Pay the card fees and spare your customers the fine for choosing your business, please.

Absolutely terrible! Service was fair and the food sucked... Looks like a cool hippie bar so I had to try it. However when I got in there it looked like the only hippie-ish people were the servers. Management looked like a bunch of death metal heads. Not my scene. Never again!

Beer: Yum! They have a huge selection on tap and lots of specials with crazy stuff on nitro. It is always an adventure in beer. I LOVE the beer with the hints of ginger and the wheats with ever changing fruits. For those who like it hoppy they have those too, I just don't love hops. Food: Try the specials! I've never been disappointed. We had a wonderful jasmine rice and black bean burrito with sweet potatoes and goat cheese topped with mango salsa. OH heaven opened up and angels sang, it was stunning. A main dish will set you back about 10.00 but the food is worth it.I do agree the fries are limp, but so many other things make up for the fries. If you have a group and are there to drink some beer grab a plate of nachos to share. Vibe: Laid back, but almost always busy. It is worth the wait. Stand at the bar and have a few free tasters as you decide on which to order. The whole staff helps out so you are never stuck waiting for your server or a refill. Even when they are busy 3 or 4 employees will stop and check on you. Overall: One of my regular favorites. Good for lunch or a snack and beer before strolling Pearl street mall. Great beer, food and people. Great for groups of 4ish not a lot of places for large groups.

The Mountain Sun and its sibling establishments are quintessentially Colorado. Good pub food, great beers (although sometimes I question how often they clean their keg lines based on how I feel the next day). The service is usually good with an occasional lapse. The fries are great if you like them with skin and fresh out of the deep-fryer. Stout Month (February) is a great tradition. Burger & a beer night (Mondays) was also a favorite time to come in. Cash (or check) only. For the three years I lived two blocks away my checkbook had two primary entrants in the register: my landlord & Mountain Sun. Chalkboard art that you'll remember long after you leave.

Holy crap, awesome beer. My boyfriend and I did a 15 brewery tour of the area and this ended up being our favorite. Just by chance we ended up sitting down for lunch right next to the brewer.

The beer is great, but my burger contained a used band-aid from the dirty hippies in the kitchen.....They refused to replace or comp the meal, and were very rude about the incident. As you can imagine, I wasn't hungry after I found the bloody stump in my food, but at least don't charge me and buy me a beer. Put some gloves on, and take care of your patrons.

I really can't add to what everyone else has written. Just concur that the beer is awesome, they have a great selection of their own and guest pours, including a nice sample on nitro.

The Mountain Sun Pub & Brewery was my introduction to Boulder, CO. It's a very unusual brewpub, in that the place in clean, light, airy, and serves healthy food. This was completely new territory! No stale smell of beer and faint echoes of cigarette smoke...where is the grime? I ordered the avocado & cheese sandwich; it was full of vegetables but was filling and delicious in spite of that. Service was prompt & friendly; I didn't see a sour face in the place. Boulder is weird, but the weirdness made for a great brewpub.

Matt S.

If you want good craft beer in Boulder, this place does not disappoint. There is a reason a place gets 4 stars from 232 (at the time) reviews. The beers are great with Mountain Sun boasting three fermenters in the back and 15+ taps. The food is something my coworker said he used to see at Phish concerts (?), but it hit the spot! Staff are phenomenal. There is a super good vibe in this diner-like cafe.

I came here looking for a place to eat (with internet) between house hunting appointments. The waitstaff was super nice and cleared off a table that was being used by the general manager working on accounts. He was very nice and came over to chat about what I was doing in Boulder, etc. Cool guy for sure. I got myself online, read the menu and realized it was Cash Only. I must have looked too sad, because as I was packing up the manager came by and said "don't worry, I'm putting you on the don't worry about it plan. Have a seat." Intrigued I sat down and the nice waiter came by and the manager said "she's on the don't worry about it plan". Turns out, they hand you an envelope, stamped no less, with their address on it. Apparently just send them the money. Well, I'm not sure if they size you up first, or since I was moving there, they figured I was good for the money, but there are NO don't worry about it plans where I come from. I must have been living in the big bad city too long. So I ordered a delicious wheat beer (they gave me 3 different kinds to try first) and a buger with fries. The meat is grass fed from Colorado, and I could really taste the flavor. Here in California, we often get New Zealand grass fed which is decidedly one note. The beef was really really good and excellent with my local brewed beer. Delicious. Anyway, after I finished my beer, my burger, and my internet browsing. I found an ATM and promptly gave them the unused envelope, my cash for my bill and a 30% tip. Yea! I heart this place so much.

Two of us went for lunch on a Sunday at noon. The service was slow, causing our meal to take 1.5 hours for 2 burgers. The food was unremarkable - burgers (one SOB burger and one buffalo) were over cooked despite requests for medium rare, and the side salad was an uninspired pile of lettuce, three tomato slices, and two onion slices (also indistinguishable from the burger toppings...). They also messed up one order slightly, but did correct the blunder. Will not be going here again. I guess people must go just for the beer.

One of the best brewpubs I've ever entered. The food is inexpensive, and like you'd hope for in a pub. It's small, crowded, young, and on the loud side (even on a Tuesday night). I ordered a mushroom, swiss and onion burger with extra mushrooms and onions. They delivered: sloppy, savory, and delicious. Excellent burger. The corn chowder was peppery and filling. The beer list varies slightly between the menu, daily specials card, and chalkboard (which features a drawing of a woman with a long ribbon in front of a a sky filled with zeppelins). They have a full spectrum of brews, including some on nitro tap and a rotating guest beer. Most beers are $4.20 per pint, and they're excellent. Companions got buzzed off of their pale ales, and my Java Porter was one of the best I've ever had. They gave me two samples of stouts for free, and I'd highly recommend them for beer snobs. Their FYIPA has a solid "A" on beer advocate, and it's a very good brewery overall. No credit cards.

This is by far my personal most favorite place to eat in Boulder. I went to CU and live in Boulder county and have been to all the inexpensive and pricey burger joints in around. Hands down MSB is ALWAYS hit the target. And WILL satisfy any burger craving! I had the junk burger - grass fed beefy ambrosia with Swiss, sauteed shrooms and onions and the usual veggie suspects with extra pickle. This was- past tense because I absorbed it- the best burger I've had all year. Nom nom!

Last night my best friend and I went out with a mutual college friend of ours who is a professor out at UCSF/CA, and we pondered for a few days beforehand where to go. We all went to CU, and had great Boulder memories, and it had been a while since my companions had spent any significant time there, so I fled to Yelp and threw out a few choices in Boulder. Narrowed it down to 2 places, Avery Brewing on E Arapahoe and Mountain Sun on Pearl. I leaned towards the Mountain Sun because that area of Boulder is just *fun*. Also, scanning Avery's website -- no food there? Bwa? I had that mostly confirmed by my manager today, they don't seem to have food at Avery Brewing! The college prof said "there will be more women at the Mountain Sun", which was an *excellent* point and eliminated any discord. =) So off we drove to the Mountain Sun. Good karma surrounded us, because a block to the north of there is an area where it's *free* parking. Near Pearl Street? On a non-Sunday? Cha-*ching*! We went in about 7:30-ish, and the place was about a 7-8 on a 1-10 busy scale - we were put on a wait list for about 15 minutes. People everywhere, animatedly discussing things, playing Trivial Pursuit, on dates, out with their family and young babies, or just commingling. It was a "good vibe" atmosphere all over! I immediately felt relaxed and back "at home". This place is not pretentious at all; it's *friendly*. I will say though, that the waitresses are busy and get busier as the night goes on, it's like a marginally-controlled chaos storm there. We were seated at a table for 4 and brought our beers from the ale counter that we'd ordered upon entering - there are about 15 beers that they brew and you can sample any one or multiple ones, before you decide what you'd like. 2 of us started with the delicious Raspberry Wheat ale; sort of looks like White Zin. Very crisp beer, light, smooth and a very mild tartness to it that left one thirsting for more. The Prof started off with the Belgian Dip Chocolate Stout, which was extremely yummy -- people who like Guinness would *looove* this stuff, it's actually made with Belgian chocolate! 2nd round was another Raspberry Wheat for my friend, I moved onto the Annapurna Amber, a very tasty medium thickness dark gold brew, and the Prof had the Colorado Kind Ale. (You know, like kind bud. Uhmmmmmm... only in beer form. [looks around edgily for cops] And without the THC, but with other tasty substances involved ^_^) All these beers were about 6% ABV, but there are stronger ones there as well if you'd like to get buzzed more quickly. All of us were starving by now, so we ordered munchables and were not disappointed. My friend had the Junk Burger (piled with a lot of tasty things) and the Prof and I each ordered the burrito - black beans, rice, green peppers, tomato, onion, monterey jack and cheddar cheese, garnished with salsa, guacamole [maybe 2-3 tbsp, a LOT] on the side, sour cream and sprinkled with diced jalapenos. It was heavenly!! We also managed to "inherit" an Isadore Java Porter that was mistakenly poured for someone and passed it around the table. It basically tastes like a rich dark porter mixed with a few shots of rich dark coffee! The 2 tastes mingle nicely - again, probably something Guinness drinkers would love. I'd *swear* it woke us up some. Was there that much coffee in there? Only the servers know for sure. The constant chatter of background noise and bustle was halted twice by cute waitresses bellowing that it was so-and-so's birthday and what their greeting wishes were; the entire bar joined in singing Happy Birthday to 1 person, and just bellowed out "Hey Matt!" for the 2nd person. You couldn't get an entire bar to stop cold and join in wishing someone Happy Birthday in most places [there are SOME exceptions] in LoDo, or South Denver...but in Boulder it just seems like second nature. It was an *awesome* expedition and I can't wait to go back again. Read the other reviews here, especially Anthony K's from 5/27 and all his hints. They DON'T TAKE PLASTIC HERE!!! *But*, they have an ATM in the back that only charges a $1 fee - a steal considering some ATMs are up to $3-4 now. If you're in central Boulder frequently, you *may* just want to make this your preferred ATM outlet -- whether you imbibe on your way out the door or not is up to you :) 3 people escaped, with full dinner platters and about 3 beers a piece, for $45-ish before tip, if my eyes focused on the bill correctly. If the platters were about $7.50 a piece, that makes our beers about $2.50-3 a piece. Really? For beers of this quality? F**king amazing. 4.5/5 stars (if there had been no wait, a straight 5 -- but hey, weird thing about great places -- they tend to be *busy* places. Also knocked 1/4 off for the greater accessibility of the wait staff/bettter acoustics so you can actually hear your companions at their sister pub, the Vine St Pub at 17th & Vine in Denver.)

Everything about this place made my heart happy. SUPER friendly and helpful staff. Excellent, juicy burger, cooked exactly as ordered (medium rare) Heaping (small) side of tasty guac Six HUGE "samples" of fantastic beer for less than $10 Games to play at your table Free samples of beer and food given out to people who were waiting Totally reminded me of McMenamin's in Seattle, which I loved Didn't hustle us out as we finished our beers, despite the line Grilled cheese w/fries, burger with chips, guac side, cup of chili and beer sampler total: $26 The only minor inconvenience - it's cash only.

Great beer and very friendly service. This was my second trip and I really enjoyed the experience this time (not that the last time was bad). On this visit, I tried a beer flight and put my fate in the hand's of my waitress - she did such a good job of selecting interesting beers that go together and matched what I was looking for. While the beers and service are great, the food is just OK. I would categorize it as high-end pub food with a heavy representation of vegetarian fare. Everything I was served was quality, but it was not adventurous or daring.

Usually I go here so I can beat my boyfriend at checkers... He gets so caught up in his beer and burger that it allows me the opportunity to cheat without him even noticing. All of a sudden, he will come back to the game and he will realize that he is losing... He will scrunch his eyes, take another swig and blame the beer... Little does he know.... Unless he reads this posting. The big community wood tables, board games and beer galore, make this a great place for a a couple different groups of people: 1) Friends (Especially out-of-town guests who care more about beer than food) 2) Family (Young families are often in there in the earlier part of dinner-time hours... So time your night accordingly 3) A date where you don't really want to or have a conversation (See, you wont even have to think of an excuse) 4) The Single Parana... A great place to meet the usually boozed up male... Or hot tom-boy girl hanging out with the guys I have never waited that long for a table, as the service is fast and the patrons are extremely hungry for some reason... hmmm, I wonder why? Other postings scream about the food, I don't feel the same way... I never find the food to be that great and I am always a little unsatisfied. On the wellness note, there are healthy sandwich options and decent vegetarian soup picks... Which temporarily keep you away from the fries. * Star one is a great urban location right on Pearl Street ** Score star two goes to MS for their sometimes free fries while you wait by the bar *** Community garden star number three is for nice large tables good for groups or meeting new friends **** Our final and last star is for having awesome brewed beer and being a guy magnet... This place can easily be a singles scene as much as a date or family scene... With groups of boys here, Mountain Sun is an ideal place to use that seductive lick of ketchup off of your lipstick that you have been practicing in the mirror lately. He, competition is tough these days, gotta differentiate yourself right?

This was one of the best meals we had all vacation. We hit many cities and this place was the stand out. I had the veggie Rubin made with Tempe and a side of french fries made in-house. We hit this place early and got the happy hour prices. We took advantage of the happy hour and tried as many local beers as we could. We tried the XXX Pale, Colorado Kind, FYIPA, Illusion Dweller IPA, and the Oatmeal Stout on my favorite nitrogen pull. I could have eaten there every night of our vacation if we stayed in Boulder.

Best beer in town. I mix the Blackberry Wheat and Java Porter together-I am that complicated-order what's not on the menu type of person. But they grin and smile and happily bring me my beer, and then another, and another, and another. I love their nachos and get major cravings for the huge pile of chips, cheese, black beans, salsa and sourcream. It's one humongus pile of goodness that's sure to leave less than 4 people stifled at how to finish the plate off. Vegetarians need not worry-there are plenty of options for veggie heads on the pub style menu including a black bean veggie burger, hummus plates and sandwiches, black bean soup, burritos, salads etc. And should you need to up the competiveness in your relationship try playing one of their games available. Currently, I am in a losing series of Connect 4-but I swear that many more Mountain Sun beers in the future will help me win!

After dinner and walking around downtown for a bit, my husband and I stopped in Mountain Sun for a drink to end the night. It was a popular choice on Saturday night because most of the tables were full. The crowd was young (mostly mid to late 20s), so we felt right at home. Service was quick and very friendly. My husband tried their amber beer which he really enjoyed. I tried one of the IPAs (unfortunately the name escapes me now - darn wine and margaritas from earlier in the night), but it was quite hoppy which doesn't bother me at all. If you are not a fan of hoppy beer, I wouldn't recommend the IPA I had, but I am fine with a hoppy beer. When I saw the handwritten bill and $5.50, I assumed that meant each beer was $5.50 which wouldn't be unreasonable in my book. Boy was I wrong! Our two beers total were $5.50. Mountain Sun is a great casual place to enjoy some beers and hang out. Again, I'm glad we listened to the recommendation of some of my husband's co-workers because we really enjoyed Mountain Sun.

eating here and not being able to drink their amazing beers because it is during the work day sucks! love the food .. never had a bad item. Fish and chips are excellent. person with me had complained about not being able to find decent F&Cs in CO and these changed their mind.

Great lunch and dinner menu, with lots of options. Delicious, healthy pub food, and decent service. Always great beers on tap. I love the nacho's and grilled cheese with tomatoes, pesto, and avocados. It gets pretty busy on weekend nights, but the appreciates you waiting, and sometimes hands out some food to keep your grumbling stomach from making too much noise. All in all, great food for the price you pay, always a place i bring out of town visitors.

Calvin F.

Went here on the recommendation of a local. The location is great, and it was super-busy. You have to go up to the bar and put your name on the list if you want a table, but you can start ordering beers while you're waiting, and they'll even attach the tab to your table when it arrives. The beer was actually rather disappointing. It was decent, sure, but nothing to write home about, especially from someplace in Boulder that bills itself as a brewery. The food was excellent, though (I had a special spicy veggie wrap with a lot of flavor), and the service was excellent; everybody was super-nice and attentive, even in spite of the place being really crowded. I could go with either a three or four on this one. Overall, it seemed like a good local hangout, but maybe not the first place to check out in town.

Meg W.

Have held up the bar here numerous times! Love the beers, the atmosphere and the friendly girls/guys behind the bar. Can only comment on the beer here and I love how you can sample each beer before committing to a pint or two. Their IPA is great, the chocolately stout and the raspberry wheat, which I usually drink in that order. Haven't tried the food here as usually I'm a happy camper after said pints (stout is like a meal in itself, isn't it?), but I've heard its good.

Shaun D.

Great beer (love the nitro options), great food, and awesome service! We've eaten here twice already since our one week stint in Boulder and love it. Try any of their chili + corn bread, Christmas style burrito, and the date night burger. Also the vegan Ruben was bangin'!

Dave S.

The beer says it all! Across the board they have tons of beers that are top notch. I may have tried more samples then actually beers I ordered. The problem started when I couldn't decide what beer to get. The food was very good as well. When you sit back and have a drink and food in front of you, look around and watch the whole staff smile, laugh, and goof around and realize this place is fun!

Anthony K.

Okay, the Mountain Sun has amazing food and beer. Here are some things to keep in mind to get the most out of the dining experience: 1) Take a look at the specials on the chalk board right when you walk in. They are creative and very tasty. 2) Go to the bar (at the back) to put your name on the wait list. Anyone at the bar will be glad to put you on the list. 3) Although this place is often crowded, don't be intimidated when it comes to choosing a beer. The staff has always been more than happy to let me take my time tasting beers to find the one I want before ordering a pint. 4) Every staff member can, and is expected to, work every role in the place, from chef to bar tender to server, so they are extremely knowledgeable about the menu and what's on tap. Don't hesitate to ask them for a recommendation! 5) Remember it's cash only. But, they do have an ATM in the back that only charges $1 service fee. Have fun!

A burger from Mountain Sun would be my last meal. I would give it 5 stars but it's so noisy in there from lack of sound proofing that sometimes it's difficult to hold a conversation. Seems like an easy enough fix and maybe someone will read this and do something about the noise. It would be perfect then. Get the Junk with cheddar and fries, you have to get the fries!

I took out of town family to Mountain Sun and everyone is super friendly. They offer free Avery beer tasting while you wait which was nice. I ordered the build your own grilled cheese which was very affordable. They were a little disorganized, the fries came out 10 minutes before the sandwiches so I ate all my fries before I got the rest of my food and my cousin's fries were cold by the time her food arrived. My husband had the burrito and it was tasty and reasonably priced. We would go back.

People love this place and I do not know why. The beer is basically good homebrew -- it is often not brewed to completion and is not filtered. The result is a hurting gut and head the following day (or even the same night on some occasions). The only food I will order is a grilled cheese or rarely, a burger (the fries are disgusting so order it with chips). I have two positive things to say about the Mountain Sun: 1) Good atmosphere (though small and quickly gets crowded) and 2) Nice, helpful employees for the most part. If you are a beer-lover and doing the beer tour thing, I highly recommend one of Boulder's other amazing breweries (particularly Avery, Boulder Beer, and Twisted Pine). If you want a chill and affordable place to relax while you're downtown (and it is not uber-crowded), stop in and have a beer but I wouldn't stay for two.

The room was great, the service stellar, and the attitude of the place is laid back and inviting. We showed up at 8:30 on a Thursday night, and there was a 30-minute wait. It wasn't a big deal, as we were able to have a pint at the bar and take a look at the tanks, as they make many of the beers that they offer in-house. When we were able to get a seat, I wasn't sure what route to take on the beer selection, so the server was kind enough to bring me a few samples based upon the direction that I was leaning. I settled on the Cleveland Brown, and at $11/pitcher I thought it was a steal, as it was a really tasty microbrew. We split a basket of fries as an appetizer, and I ordered the Black Bean Burger. My friend ordered the Grilled Cheese with sauteed mushrooms and onions. Both sandwiches were accompanied by chips, but substitutions are an option no problem. Credit Cards are not accepted, so be sure to bring cash. The black bean burger was tasty, but it was messy! I might not get it again next time for this reason, but all in all I definitely don't regret the order. I'm really glad that I stumbled upon Mountain Sun. If you don't mind a bit of a wait, it's worth it. Check it out. You'll be glad that you did.

Stopped in for lunch and a pitcher of beer. I'm a bit of a beer geek and the FYIPA did not disappoint. The food and service were both excellent. Had a steak sandwich that was on special, it was wonderfully spicy with just the right amount of heat. Thanks to Annie our wonderful server for a fantastic experience. My only negative is around the policy not to accept credit cards. A bit of a hassle.

Mountain sun has amazing burgers and beer. The staff is fast, friendly and well in tune with their customers. They brew their bear on site and I got an awesome tour from the manager. Their menu has just about anything you could ask for from a pub - including vegetarian options. The portions were large, taste shows a clear dedication to quality ingredients. The fries are unreal and thankfully not salted so you can put on what you want. I ate there with my 3 year old son and 74 year old father and both were very happy with their food! The beer is cheap and has real flavor. Bottom line: Great service, food & beer and a LOW cost.

I love this place. I feel really lucky that I got to re-introduce myself to the Pearl Street Mall via this brewery. The crowd was a delightful mix of students, locals, tourists and all around beer lovers. I am not usually a fan of the dark, sandwich-in-a-glass beer, but the selection was so vast and there were too many flavors not to at least try. The chocolate was surprisingly exceptional. Lucky for me to be with such a connoisseur of the heavy beers. Although it was packed, the hostess went out of her way to find us a table and as loud as it was, the cozy 2-tops were perfect for intimate conversations and light flirting. Not that I ever flirt. The nachos were fantastic, and good thing because big beers + no food = Bad Sherri. The cheese was melty and good, and it was a heaping mound of pure late-night goodness. Our server was cool, and helpful in making choices and keeping us abreast of really important things like when the kitchen was closing and/or when HH was ending. Oh yeah they have a 4 hour HH. Bonus. I can't wait to get back~

Great Boulder experience, highly recommended. I had dinner here with family back in June 2009. This was one of my best dining experiences in Boulder this year. Sorry my review is a little light, I ate/drank at Mountain Sun five months ago and am only now getting around to yelping it. Better late than never, though.

Order the tasting flight of beers. You'll experience an adventure & a buzz. The CU sandwich was awesome. The veg chili was tasty too. The place was packed at 2 pm, so I can just imagine the crowd at prime time. The wait staff sport smiles. They gave free beer samples while we waited for a table & then served us extra French fries just because they had an abundance and were hot. Great place if you can get a table.

Kyle A.

This lovely pub is worth 5 stars in terms of their staff and service which is top-notch, homey, welcoming, and warm. Their beer is worth a million stars in my opinion. They have every range and style of beer imaginable and they rotate a lot! I'm giving 4 stars only because they are a cash-only place and that bugs me a bit. The first time I went in here I was a bit overwhelmed because the place is always busy and there are no seats at the bar. The bartender was very kind and offered me tasters of almost everything. Instead of me having to ask him to try some, he just kept bringing me tasters of brews he thought I would like based off the types of beers I told him I enjoyed. After trying about 8 beers, I finally settled on a fantastic summer saison. Since he knew it was my first time here, he gave me my beer for free! Amazing hospitality! Sunday nights they have live bands, and the place just has this great, inviting feeling. The color and decÃ³r is hip and very fitting to Boulder's personality. I heard their sister pubs in south Boulder and Denver are amazing as well. I can't wait to try them out!

We went three times in two days! Best of both worlds for me and husband -- very tasty, healthy-ish, and inexpensive food for me, and outstanding beers for him. Dunno what they put in their chicken but it's awesome compared to boring dry stuff at most places. Great vibe and we loved the board games.

You have redeemed yourself, Over, and over, and over again, it has taken me a while to update this review, because we wanted to dine here quite a few more times.

My husband and I drove up to Boulder to hang out on our day off. We wandered around the pearl st. mall and asked a few people for recommendations and Mountain Sun kept being mentioned. It has been a while but I do remember we both loved our food. We had the Junk burger, with no mushrooms for me. Of course we had their fries and we even asked for some garlic mayo on the side to dip. We split a beer sampler of 6 beers. It included Quinns Golden Ale, Isadores Java Porter, XXX Pale Ale, some sort of Lemongrass spearmint beer that was a limited time offereing. I really liked Quinns Golden Ale. I was excited to try the Raspberry Wheat, but they were all out. I plan on trying their new Denver location. I am already looking forward to the fries and Raspbery Wheat.

On a weekend trip in Boulder, we stumbled into this spot for lunch. It was packed, so we waited at the standup bar and had a few beers. Really awesome beer - unique types and flavors. I had a raspberry beer which I thoroughly enjoyed. We were seated after about 15 minutes, and we ordered sandwiches for lunch. My pesto grilled cheese sandwich really hit the spot. My boyfriend had some variety of a chicken sandwich - also good. The food was great, the beer was better, and it was good value for the money spent. Also right on Pearl Street - a plus for a tourist who is walking the Pearl Street strip. I would recommend to tourists and locals alike!

We stopped by Mountain Sun for a bite to eat on the way to Avery brewing. Got to hang out with the brewer, Nate who was very Kind to take time and talk about their beer and the business and show me around the brewery. Nate was so generous he even offered to buy us a round. I had a F.Y.I.P.A and Basil Blue Cheeseburger and what a sublime pairing that is. The Vietnamese sandwich was delicious too! Hat tip to everyone at Mountain Sun Brewery. Cant' wait to go back to Boulder!

Gretchen W.

This review holds true for both the Mountain Sun and Southern Sun, so you will see it posted at both. What the Mountain/Southern Sun gets right the others just don't seem to get: just be authentic, unassuming and unpretentious. Be consistent, be friendly, and don't try to upsell or push appetizers or desserts. The Suns hit the mark on quality, and they don't seem to try to do anything more. And why would they, when they're succeeding at what they do best. I believe the quality of the beer and food and the friendliness of the staff and commitment of the management team shines through to reflect the spontaneous community ethic advertised in the pub decor homage to touring jam bands like the Grateful Dead (whose following was, by all reports, a friendly and communal atmosphere). Many restaurant chains and "concepts" try to imitate this subtle feeling through decor and advertising, but they're just imitating. The Suns are the authentic item, the real deal. 5 stars for the beer: easily the best beers I've had at any microbrewery in the State of Colorado; far surpassing those of any brewery in the Boulder area. The waitstaff have been, in my experience, extremely knowledgeable and helpful when it comes to picking out the right beer to suit my tastes for the evening. They know a lot about what's on tap, and how it compares to beers of similar class made by other breweries small and large. Beer is a fine art at the Mountain Sun! It's worth your time and liver to sample as many as you can. 5 stars for the nachos: served piping hot with real cheese, whole black beans and excellent salsa. A whole order is a perfect filling split between 4 when paired with a pitcher. 4 stars overall for the food: it's very consistent and always good. It's so much better than any other pub fare in Boulder. Places like the Walnut Brewery try to be "classier" but end up falling on their faces when it comes to consistency. Conner O'Neil's tries to have that Irish Pub atmosphere but feels fake and the food is rarely of the caliber to stand up to their standard imported beers. The Suns have figured out how to make consistently good food and are sticking with it. I recommend coming in for the specials, such as fish&chips night. 3 stars for the atmosphere -- pure Boulder -- crowded, noisy, and people hanging around for a long time over books and games. The interior hand-painted and hand-chalked art is wonderful in a summer concert jam band traveler sort of way. People who frequent the Suns are friendly types, usually kind and polite, not jostling and rude and creepy as it can be at similarly crowded places (The Med). While it's loud, it's not frat-boy loud nor sports-bar loud --it's just loud because everyone is conversing and trying to hear/be heard. And I'm really glad there are no TVs. Whoever needs an electronic feed should seek elsewhere. Again, the Suns focus on doing what they do best, not trying to be like everyone else. 3 stars for the service: I've been coming to the Mountain Sun at odd intervals throughout the year for 5 years, and the service is consistently friendly every time. It has also recently improved to be more prompt, even during the busy times. I do have some friends who've received poor/unfriendly service, however, and due to that simply refuse to join me at the Mountain Sun. This is sad because part of the appeal of the Mountain Sun is that it's a friendly place to hang out with friends and share a pitcher. So, while my experience is always good, I am concerned about my friends. I think this is an area that could still use some investigation, but the improvement in the past year is noteworthy. Many reviewers complain that the Suns are cash-only. I know that there's a very high cost involved with using credit cards at a business--a significant percentage of each transaction. Usually, this cost is passed onto the customer in higher prices. I appreciate that the Suns are keeping customer costs down at the expense of a tiny inconvenience. Really folks, is it so hard to stop at your bank's ATM for cash on the way, or to use the ATM in each Sun location?

Nachos are of legend status here. Really good its nearly a fourteener they are piled so high. They use real cheese and not that liquid queso crap. Also had a salad, which was decent. I would have preferred something more tossed instead of big chunks of veggies on top of lettuce. But, they were fresh veggies...I'll give them that. -1 point for not taking credit cards. +2 points for giving me a self-addressed stamped envelope and told me to just send them a check in the mail instead of paying the outrageous ATM fee. They almost deserve 5 stars for that ridiculously high level of customer service.

George D.

I'm still not exactly sure what having beer "on nitrogen" means or if it makes things better, but that option is available here. I enjoyed their beverages thoroughly. The cheese fries were a welcome side dish as well to accompany beer consumption. Played a few games of Connect 4. Was disappointed that they didn't have a deck of Uno cards though. Articles cut out from The Onion graced the walls of the men's bathroom. However, a bathing hippie graced the sink as well. But its Boulder, after all, so that was to be expected...

A pretty chill place that we started the night off at for my friend's birthday. They had a good selection of beer and a decent bar menu. The whole vibe of the place was pretty chill and fun. My friend brought a boardgame for us to place while we drank our first rounds. The java beer was pretty intense. The manager/guy in charge and our waitress was pretty awesome, because my friend's party kept on growing and he totally hooked us up with another table and was super accomodating. The entire bar sang happy birthday to my friend too! Definitely a fun place to taste a whole lot of beers.

I hope my star-rating doesn't confuse anyone. I'm a huge fan of Mountain Sun for what they offer- amazing micro brews and decent food for cheap. I however dislike sun due to the rude waitstaff and frequently pretentious clientele. I find this to be contradictory- don't pretentious people like good service? Maybe they are regulars or something and actually get good service. I don't know. In short, go for the great beer (4 stars), cheap and decent food (3 stars) and don't expect much from the employees. Also expect to wait for at least an hour on Thursday, Friday and Saturday nights.

Seriously LOUD and seriously good beer. Try the Dropkick Stout mixed with Blackberry Wheat or the XXX Ale. Damn good dark beers. Service was slow but it was Memorial Day so I cut them some slack. Vegetarian chili is tasty and the pulled pork special had a strong mustard flavor but was delicious. The table next to us ordered a burger that wasn't cooked exactly how the diner wanted it, and the manager did not hesitate to recook another burger for him and comp it. Nicely done. And I have to give a shout out to big man behind the bar. You know who you are--big, muscular dude with the beard. Woo wee.

This place is "like" TOTALLY Boulder. For all you Dead Heads--they have lots of Grateful Dead memorabilia. The beer is brewed on-site. They also have homemade root beer (with no high fructose corn syrup). This is what I had and it was really delicious. This is a fun place with inexpensive and GOOD food located on Pearl Street Mall. I feel like I'm in a time warp from the sixties!

Great microbrews and chill atmosphere. After a day of hiking and chowing down at another place down the street we were looking for a local spot to taste where the locals go. It's cash only, but I heard that they'll give you an envelope with a stamp to send cash back if you don't have it on you. Not sure if that's true, but seriously friendly way of doing business. They have music on Sundays, which we didn't get a chance to experience, but got to see them rearrange the room by physically lifting people already in chairs and moving them. It was quite a scene.

Ten years ago I was a regular at Mountain Sun, which to my mind reflects all the best that Boulder has to offer. I'm happy to report that nothing essential has changed in the past 10 years, this place continues to be the gastronomical beating heart of Boulder. Everything here is good, and beware: when you order a full plate of the nachos, a mountain of cheese and chips will arrive at your table.

Laid back, hippy-esque brewpub. The beer was good, and the sampler is generous, I definitely recommend it. The staff was incredibly helpful in selecting and recommending beers. Food-wise, they have a veggie selection, and the hummus sandwich is good, but not great. Apparently the staff is on a total rotation, so you might have different waiters throughout your meal. This just adds to the laid-back atmosphere, and along with the various board games to choose from, makes you feel welcome and not rushed.

So I really wanted to be vindictive and give the place a two-star rating at most after my experience yesterday. I took a long shower this morning though and mulled over what exactly the Mountain Sun is and how I should actually approach this review. Certain establishments should be rated on different scales; you couldn't possibly, or at least fairly, compare Red Robin to a place like L'atelier right? With that same thought in mind, I can't reasonably compare my experience at the Mountain Sun with my subsequent experience at The Boulder Cafe. Went to happy hour right around 4pm on Friday with my buddy Jon and were really baffled by the service we received. One of the servers impatiently asked if we knew what we wanted just as we began to consult the menu. Not quick enough on the draw, she left to fetch us some water, as we sat trying to decide what kind of beer we wanted. Here's the thing: the water never came. Server 1 saunters off and up comes server 2. I ask if they have any happy hour food specials to which she kind of chuckles and says no. Well, that's fine, we'll just get some beer for now. Server 2 goes off for a while, server 1 comes back and is slightly baffled that we don't have waters yet. I am baffled as well, even more so when she disappears again never to return with water. Server 2 eventually comes with our beer, leaving Jon and I to wonder what the hell is going on. In retrospect, I don't think anything was going on. I realize I have failed to convey the weird, ambiguous attitude we received from our servers; other yelpers seem to interpret this as "laid back" and "casual" service, which I can understand now. What I think happens here is a "Tragedy of the Commons" in a restaurant setting, the servers are continuously rotating tables so there is little incentive to try and be somewhat friendly to patrons. But enough of that. The beer here is great, brewed in house, and reasonably priced. I assume the burgers and vegetarian chili are tasty as well, since this is a sister pub to the Southern Sun (a place I have frequented more than a few times). Perhaps my friend and I just arrived at the wrong time, as this place definitely seems more hoppin' in the latter hours of the night. I will certainly give the Mountain Sun another try, albeit with my chin up and a stiff upper lip to boot.

Top notch experience at Mountain Sun Pub & Brewery. The people here are super nice. The beer we had was delicious. We are hop-heads, and they had more than a few choices to fullfill that need. We had a hard time deciding what to eat, as everything on the menu sounded so delicious. I had the burito with chicken - mouth watering, savory, spicy red chili sauce, absolutely delicious. My husband had the fish and chips and he was all smiles. It was really good. All around, this place is a must go to if you like tasty beer and food. Hopefully we'll head home with a growler of the FYIPA, or the Resinous Rye. (Their Growlers look like giant mason jars!)

aha...just what the Mountain Sun on Pearl in Boulder needs...another Yelp review. Such a variety of perceptions...I simply must throw in my 2 cents worth, for whatever it's worth....the first correct answer wins a prize!! It's the plethora of choices of grilled cheese that have made me love this place. I have not tried the grilled cheese at the other location(s) just here. Always good. Verrry cheap. Nice to play a board game here, and I like the friendly service. When it is crowded at dinner time, it is sometimes a little daunting to make one's way through the gauntlet of the entire length of the restaurant to put one's name on a waiting list. But the upside of this process is that sometimes you can meet a new friend or two while making the pilgrim's progress up to the bar to get on the wait list. Still, it's a relief to successfully happen in during an uncrowded time. This is rare. Such is success in the restaurant world. I love you, Mountain Sun, because grilled cheese sandwiches with real cheese, on whole grain fresh bread, at a reasonable price, are just what I need sometimes, along with your tasty root beer that I enjoy and your many beers 'most everyone else enjoys, and your beautiful absence of TV, which I appreciate greatly.

I'd heard my bro & sis-in-law rave about this place -- it's true. They served a free burrito at the bar while we waited. The avocado veg sandwich was really tasty and their red wine was decent. Run here if you like beer (I don't). They've got a great selection of their own brews and a few "visiting" brews.

Mitchell F.

Immediately after finishing our dinner at Mountain Sun's sister restaurant, Southern Sun (see that review as well), we met a friend here for another pint. After getting a taste of the great brew earlier in the night, we had to get some more. While Southern Sun was getting quiet when we left, Mountain Sun was just picking up when we arrived. A local band was setting up, and the place was packed. ...Maybe a little TOO packed. We had a hard time having much of a conversation, and the crowd around the bar made getting another beer quite a challenge. I think this place is definitely worth a second try, however, and the setting might have been perfect if we were just looking to groove to a great local band.

This used to be one of my fav stops on Pearl Street. ( I left boulder about a year ago). The pitchers are cheap, the beer is SOOOO good, and for a bar I really like the food. I love the raspberry beer ( a theme in my brewery visits). It even has a nice pink hue to it which i found interesting. I also really like the chocolate stout... but only to taste. I don't think I could drink a whole glass. Same with the espresso stout. I love how they basically will let you sample 3 or 4 beers for free ( i think they are supposed to charge you, but I was never charged). I always got the blackbean veggie burger (so Boulder) and I was never disappointed. I love it. The price is right and it goes great with beer! Perfect! Then you can stay, chill, listen to some music, chat with your friends and drink more beer! Other than the fact that it is always crowded and its VERY loud, if you get a table, keep it and enjoy yourself. Great local vibe and food and drinks.

Tho we don't live in Boulder we visit friends here sometimes. Tho the Mountain Sun is not our favorite place to eat, and it is always so crowded and you have to navigate through the crowds to the back to get on the waiting list in order to get seated, we still like to eat here because of good beer, good music, and good cheap grub. I've gotta say something about what Sarah M. mentioned...the people who eat at Mountain Sun are generally outdoorsy super health nuts who have probably just been out mountain biking, mountain climbing, jogging, or one of their other triathlete pursuits. This is probably why Sarah did not like the smell of real, active, athletic humans who stop in to get a bite to eat before going home to shower. We've always had casual and laid-back but passable service. No place pleases everyone, but I'd rather that a place smell like humans than chemical disinfectants. Sterility is what I loathe. 'nuff said.

I like this place and I like their beer. This is the place you go when you want dinner to revolve more around drinking, than eating. Don't get me wrong they have good burgers and sandwiches as well, but their beer is king here. Four things the Mountain Sun should do though: 1. Tell the table wiper person to water-down the damn Chlorox before wiping all the tables before lunch. Seriously, ever wonder what the Chlorox factory smells like? Step inside their doors between the hours of 11:30 am and 1 pm. It smells like someone shot Chlorox out of a water canon into the restaurant. 2. Stop putting an entire industrial-sized-can of black beans on your nachos! Look...black beans are good and I like them but having nearly 400 of the little suckers on your nachos is not cool! 3. Have live music more than one night a week. 4. Whoever keeps stealing the damn Connect Four pieces out of the box on the game shelf, please put them back! Kinda hard to play Connect Four when you have 7 black pieces and 9 red ones. Know what happens??? No one can win the game. Perhaps that is the point.

This review is a bit late as I went there a few weeks ago for some brews and grub after a day of hiking and went back again just this past weekend. As before it was a full house and very loud. I found it hard to hear and be heard by the person in front of me but the beer is good. Had the java porter and it was smooth and rich and full of good chocolate flavor. I ordered the half order of nachos after being warned how large it was and it was good typical pub food. Being the weekend I parked in the parking structure across the street for free. Not sure if I'd go back. Like the beer but don't care for the noise.

I am writing off my first experience here as a one-time bad day because since then I have had the most exceptional service I think I've ever encountered since moving here. Last night, we were handed free nitro samples at the front while waiting for our table, then we ordered a pitcher, and then arrived three more full sample glasses of another beer we had been debating. We all loved the Pearl Street Porter pitcher and the Rye-PA samples equally. FYI that Rye-PA is going away soon, they only made a few kegs of it, darn. Since my vegetarian little brother is in town, I knew he would dig the menu and the beer-baked tempeh reuben made him a happy camper. The tempeh was a different, darker color than when I tried it before, and it tasted much better. My husband inhaled the pulled pork-ham-bacon sandwich but for the first time maybe in my entire life, I finished my burger before him. It was topped with a basil-blue cheese puree and freaking delicious. I would have sucked up that sauce with a straw, however there wasn't any left on my plate because I had already dipped all my fries in it. We chased down every hand-cut salty crispy fry from all three plates. During this rapid food shoveling, we had numerous friendly servers stopping by our table every few minutes asking if we needed anything, refilling our waters, making sure the food was good...similar to our last experience at Vine Street Pub. This was what I pictured in my head on my first visit to Boulder...an idyllic pub filled with happy high-on-life people, tasty fresh inexpensive food and a long list of delicious beers. The only complaint is that they don't serve wings like Vine Street and Southern Sun, because they are the best wings I've ever had. PS you can get cheap pints during happy hour 4-6pm.

Predictable heady chill brewpub in Boulder. Their beer was excellent. On their menu it says something about how there are no "jobs" at Mountain Sun, that everyone that works there does every job, from cooking to waiting tables to cleaning. This results in disjointed service, which usually benefits you - there's several people waiting on you and they're not all doing the best job of keeping track of what you order, so you get free beer pretty frequently. They're all nice kids, though. As for the food, it's alright. I see this place has plenty of other reviews that probably go into the food issue in more depth than I will - but for the record, whoever described the vegetarian black bean burger as "so Boulder" is a fucking idiot. You, madam, is a dumb bitch. Overall, their food is so-so. There's a major gap between quality of beer versus quality of food. Solid college town brewpub.

Matt Q.

I almost walked away because of a wait list but a waiter stopped me and quickly made a table available (that's service). A ordered a quesadilla the turned out to be 8 inches wide and generous portions of sour cream, salsa and guacamole, and regretted having to polish off a whole basket of fries. The beer selection was excellent. The atmosphere lively and on the hippie side but not obnoxiously so. It's ideal location on Pearl Street means that afterward there is always a street performer for a cheap show. It is cash only with no ATM on site, however if you can't pay they give you a "Karma Envelope" with the bill and you can mail in. Okay a little obnoxious and I don't believe in Karma but I imagine most people pay out in reciprocation of trust.

Every few months I crave a delicious, juicy burger and this is where I go. It's a spiritual experience for me. I have to close my eyes and savor the delicious moment (and thank that cow.) I'm also quite smitten with their chicken burrito. A perfect blend of textures and flavors. Atmosphere-wise, I like that it's friendly and lively in here. This has the downside of sometimes being too loud for my mood. The wait-staff is friendly, and come to think of it, they seem to always be in a good mood. They are team-oriented so you may have several people attending to you, which (usually) makes for good service. And though they are a brewery, I am not much of a drinker, so can't say much about their beer, but I know their selection is loved by many.

This place has amazing food for a restaurant, not to mention a pub! Everything I've ever eaten here has been amazing. They also have a million different things on tap and will let you taste whatever you like. And the wait staff is really friendly. If it weren't for the following downsides, I would probably want to come here every day: It gets pretty loud in there, and it can get really packed, even on a weeknight. And while I admit that those qualities have deterred me a couple times, I still love this place.

Mountain sun has great beer and a great atmosphere. The food is decent, nothing spectacular but is what I would expect from a little brewery. We got there early enough to get a table, but it can get very packed later at night. Our table was too big for us, so they asked us to move. It was no problem for us, but they comped some of our beer anyway! Mountain Sun is for sure worth checking out.

I really like it here. Great location and does a wonderful job of epitomizing Boulder. Unfortunately it's often very busy, but it says a lot about it's reputation and popularity. The only complaint I have about the place is that it does not accept credit cards. However, there is an ATM provided on site. I have yet to try their beer but I know it's a great hit and one of the many reasons people frequent the pub. The vibe is incredible. Welcoming, homey, earthy, happy, casual, and (as odd as it may sound) accepting. The restaurant has a humble approach to waitressing (the story is described on the menu). It's a very shared job here. If a waitress notices that a table is in need, she or he will assist that table. Another personal favorite about this place is the trivial pursuit cards they have on hand. They provide a few games and entrainment pieces for their customers. I come here with my parents when they visit at school and we love it here.

Jimie D.

Mountain Sun has delicious food, great atmosphere, very friendly employees, and free samples of beer upon request. Sometimes it is impossible to get a table because this place is so busy. I have put my name on the wait-list and waited at the bar for an hour or more. The beer they brew here is superb and the food is great. Some of my favorite things have been the build your own grilled cheese, and bratwurst. I dislike their salsa - however, I hear many love it.

I loved everything about this place. The food was tasty, the beer was unique and delicious (with plenty of choices), and the servers were the friendliest I've ever encountered. They even handed out free quesadilla slices to people waiting for tables to become available. If you're ever in Boulder you have to come here.

This restaurant's atmosphere is wonderful; fun and lively. They decorate the walls with Grateful Dead posters, rugs from South America(?) and sculptures. The placed is loud and lively. There were lots of people here for a friendly good time. Mountain Sun Pub and Brew even have a shelf for board games. Good times with friends are found here. Their staff are very helpful. They stop by very often. In fact, I say that because three different individuals came and checked with our group to ensure everything is OK. Now, let talk about the food. Attention mushroom lovers, go straight for the Boom Boom Sandwich. Its a tasty portabello with zesty balsamic sauce. The bread is unique crunchy and perfectly warm. The Gooney Bird Turkey Sandwich is fine. Not the best, but still good. Their fries are extra crispy. If you're a fan of crispy fries, then definitely get the fries. But you're probably here for the beer, and the beer does not disappoint. Awesome selection, and each one of these the waiter took his time to explain their complexities. Hoppy or light? Strong dark taste? He'll tell each of them to you. I went for their sampler. Ginger flavor in beer? Wow, interesting in deed. One thing that they miss in today's modern, high tech, fast pace world. What do you mean cash only? I have trouble imagining that money only works in the form of paper!

Wife and I had lunch at Mtn. Sun and we are now fans. She had the basil blue cheeseburger and absolutely loved it! Said it was a 10 of 10s. I had the blackened chicken sandwich and really enjoyed it (perhaps an 8 out of 10). Noticed many in the Pub were ordering burgers in our general area of seating. Service was outstanding-servers constantly checking to see if our drinks were full and that we were happy with the food prep. Place was packed. Its a very noisy place but the food and servers made the lunch worth it all. Would describe ambiance as a bit like the 60s and 70s-not great but ok. Worth the money....cannot speak to the alcoholic drinks as we had unsweetened raspberry ice teas and we loved those. Biggest negative: They do not accept credit cards so bring cash....or a check if its a local patron.

Thurein P.

The home of my favorite beers in Boulder. Their FYI IPA & Java Porter rival any brew I've ever had the good fortune of drinking. The food is excellent to decent but very well priced. I would suggest the basil blue cheese burger or the enormous mound of nachos. Unfortunately the delicious chicken wings that are available at the more family-oriented sister establishment, the Southern Sun, are not available here. The nights to come to the Mountain Sun are Tuesdays and Sundays. On Tuesdays, one can enjoy happy hour priced pints ($2.25!) of their fantastic brews all night long if you're wearing one of their T-shirts/apparel. Don't have a T-shirt ? Well, buy one! They have great designs on them and you'll get a free beer with that purchase! T-shirt Tuesdays do tend to be very crowded and loud, and you may rub shoulders with some of the hippier patrons. For a more relaxing evening, Sunday nights feature live local music (tends towards folk/blue grass) and a less rowdy crowd. Although there are always people to dance with.

This is my first review as a Boulderite. I used to live here for many years, but I moved to the Bay Area to get my graduate degree in food snobbery. Now I'm back and I'm ready to tell it like it is. Went on a Friday night and had to wait about 20 minutes for a 2 top, which was expected. This place is somewhat legendary in Boulder and is very popular, with waits typical all week long (the south Boulder location is even worse). The crowd was mostly college-aged, with a few 30s and up sprinkled in. Had a pint of the Quinns Golden ale, which is one of their lighter beers - very delicious. While waiting for our table at the bar, a server passed around some quesadilla slices. Nice touch. Once seated, the wife and I decided to split a burger with fries, plus I ordered a grilled cheese while she got a cup of chili. They serve grass-fed beef there, which is appreciated, but we really miss the buffalo burgers that used to be available in the olden days. I gotta say, the burger was cooked perfectly medium-rare, and the grilled cheese was pretty damn good. Washed down with another beer, and I was pretty happy. On the downside, the chili was just "eh," and the fries were too soggy for my taste, although we did eat them all. For a Colorado burger joint, this place has everything you could want, from the jam-band concert posters on the wall to the tattooed wait staff to the top-notch microbrews. I only knocked off a star for the gooey fries and the weak chili. Service was fantastic, although the place was a bit loud.

No reservations, but they are very friendly and will help you at the bar to get a table ASAP. We tried some beers while we were up there and I found my beer of the night, the ginger beer. I could smell the ginger every time I was about to take a sip, so yum! Being a non-meat eater, I ordered the black bean burger and oh, have I been dreaming about it ever since. The b/f got the regular hamburger and he loved every bit of it. Prices are reasonable and the staff is very friendly. We were even asked if it were ok for them to seat a quiet baby next to us (yes, the parents were with it). If I am in the area again, this will be a must on my list of places to visit.

Awesome selection of veggie bar food- I had the tempeh reuben, but it was a tough choice...there were so many other awesome looking options: veggie chili, veggie burritos, wraps, quesadillas, burgers, sandwiches, etc. All under $10. Great beer too, and friendly service. The beers were almost $4 a pint which seems a bit steep to me...and the Yahtzee had no dice and no score cards, just the cups. Now what kind of Yahtzee is that?? Oh, I wish they had outdoor seating...

Andrea G.

My husband had the Junk Burger and I had a regular cheeseburger. The burgers were tasty, but not quite as seasoned/juicy as I was expecting. The hand cut fries were a treat. They have a pretty good selection of beers, and the staff is all very friendly. We arrived about 5:30 on Thursday and the wait was about 20 minutes, but you're able to grab a beer while you wait, and the servers walk around with samples of the appetizers. Will definitely be returning in the future.

Elaine E.

Didn't get to sample any of their food, but it looked pretty damn good. I was there strictly for the beer. I had some kind of speciality brew - lemongrass something something (super helpful, huh?) - that was down right amazing. We didn't stay long (we were touring 4 other breweries) but one of the servers agreed to give us a tour even though they were absolutely hopping. Of course, that was after they did their staff bar slam (not sure what the shot was...) Would definitely go back to try the food. Was also slightly alarmed at the smell of BO around me. I think it was just some of the trustafarians but not something that I'd like to encounter while eating.

Trixie D.

I went here on a beautiful Friday afternoon and was able to get a table right away. My husband and I came to grab a beer and an appetizer, but decided to have lunch when we saw that they had vegetarian green chili on the menu. I started the meal out with a Colorado Kind Pale Ale on nitro. It was a bit of a wait (nitro takes longer to our and the keg happened to run out while mine was being poured). It was pretty good, but I would suggest getting a regular one on CO2. As far as food, I went with a garden burger topped with Swiss, mushrooms, and onions. I upgraded to fries ($1 up charge). My husband got the vegetarian burrito smothered with green chili - this was by far better than my meal, but kinda heavy for lunch. I had an Oaklord Oatmeal Stout next, which was divine. I'm not sure if I would wait an hour for a table since there isn't really a good place to wait, but I would definitely return the next time I am in Boulder.

Mountain Sun is like Southern Sun, but worse in several ways: first, it is more cramped, which means the loud music and the loud talk make this place especially susceptible to...noise.....; second, the service here is spottier than at Southern Sun. Why this is, I'm not exactly sure....but the difference was pretty stark; third, it is on Pearl Street which makes parking pretty obnoxious; and fourth and finally, they played some of the worst prog. rock/stoner rock I've ever heard in my life there the last time I was there. Dissonance just isn't cool at a restaurant, especially for 2 hours. Anyway, go to Southern Sun instead...better service, easier to get to, and less annoying in the noise department. From what I could tell, the food and beer were naturally the same: good and excellent respectively.

Donald H.

This place is so cool! I went in with a few people during a business trip, mainly looking for some good beer, and was extremely happy we ended up here. I had an amber brew and two blondes which were all pretty good. The blondes reminded me of some fine Belgian beers, closely resembling Delirium Tremins. I had a Vietnamese sandwich on Ciabatta which was different in a good way. Overall, great place for a beer and food.

A friend of mine was driving his newly purchased '81 Westfalia from SLC to Pennsylvania and stopped through Denver on the way. I love when friends come into town. JDubbs and I usually have a routine of doing laundry and catching up. I know. Weird. After laundry and a thorough butt kicking at the pinball machines at 3 Kings, I suggested we go up to Red Rocks.....of course. But JDubbs said he'd never been to Boulder. So off we went at 3pm to soak in the Boulder 'culture.' We walked up and down Pearl Street when I remembered I hadn't been in the Mountain Sun brewery in years. So, we stopped in for the start of our Boulder beer tour. And...................4 hours later still standing at the bar......... JDubbs and I tried the Colorado Kind Ale (10 stars!!) and the IPA and some other beers which I can't quite remember right now because we had a lot of beer. We were even privy to try to Creeper ( I think because, well, I had a fantastic buzz happening) which was a mix of the Kind and the IPA. The bar staff passed around some quesadilla to sample and even gave JDubbs and me a grilled cheese on the house. And it was cheap to boot!!! And what would top off a trip to Boulder but a deep philosophical discussion about Religion at the bar. That and the fact that JDubbs hit on a lesbian his Boulder experience was complete.

This is the best beer pub in Boulder and rivals anything in any other state I have been in. These guys brew everything in the back of the house and I am quite fond of the Colorado Kind and any Porter or Stout they have on tap (and if they have it on Nitro you absolutely must order whatever it is)! They have a late night happy hour which is a steal. The five stars are for the beer cuz the food is just so so. But seriously their beer turns anything you are eating into gold. Their beer has the Midas Touch.

Awesome! The beer was great, we were offered samples during our wait for the table which allowed for us to order beers better to our liking. Food was really delicious and staff was very attentive and friendly. It was definitely a hot spot!

I have been going to this pub since its inception. They have opened another south of town with very consistent results. Since moving from Boulder I have been hard pressed to find similarly tasty, hoppy brew (and nachos that equal theirs). In my search for tasty, quality, hoppy stuff, a close second in quality, color and flavor in my opinion has been the Standing Stone Brewery in Ashland, Oregon. At the Mountain Sun, I have to say I love the nachos. A small order is more like a "large medium." Their fearless use of black beans and fresh salsa has made me an addict. Staff: their baseline service is decent but can be inconsistent in terms of how fast they round on you. On the other hand, they rotate the staff in all positions which gives the place more of a family business vibe. Beer selection: HOPPY, flavorful, broad spectrum within the hoppy bandwidth... Fact is, because I don't visit Boulder frequently enough I typically crawl into a pitcher of the nitro Kind and/or Triple X and am quite satisfied.

Delicious beer of all sorts, great food, fun atmosphere (colorful decor instead of TVs). Juicy, ethically raised burgers, super fresh salads, and an interesting assortment of other foods for both vegetarians and meat-eaters. If the green chili stew is available, order it! Count on waiting for a table if you show up in the evening, as it's nearly always packed. Don't go if you are claustrophobic or if you are looking for peace and quiet. Also, be forewarned that they don't accept credit cards (although they have an ATM on site). The service is consistently excellent, friendly and attentive without seeming forced. This place makes you feel welcome.

My first restaurant visit in this fine city of Boulder CO! Blackened chicken sandwich was delicious and it was def. worth the extra buck for french fries. They have a Monday lunch special where a beer is only 2 bucks with an entree. Will be back for sure. Love the vibe and funny names for the beer and food. I see many nights here in my future... Just remember, they only take cash.

Rating: 1 Star * Although this is a huge favorite of locals here, remember that I am only rating this on how gluten free friendly and tasty a restaurant is. The staff is uneducated and not familiar with gluten at all. Even when the manager comes out to try and help, the only thing that I can end up getting is a very crappy salad and a burger (which I will say is tasty) wrapped in lettuce. I would skip this place for sure if you are looking for a nice GF meal. More gluten-free reviews at: glutenfreeboulder.com or find us on Facebook!

Place was PACKED!! Went on a Friday around 6. We actually waited for about an hour, which normally I wouldn't do. Although we had beers while we were waiting and I didn't want to go somewhere else after that. We were given our choice of free appetizer for waiting so long, and that was a great gesture. The service was excellent! The waiter was friendly, knowledgeable about the beer selection and attentive. All pluses. :) Good food, good fun! Oh, and the pricing was right as well! Cash or local check only, though. So be prepared for that!

GREAT BEER! Decent food. The only bad thing about this place are the kids eating here. IMAGINE.. the beer is so good here there is almost a line of students buying the beer by the gallon (growler) haha! IF you're a beer fan, you must come! Get the tasters! Very friendly staff and you don't have to deal with the attitude I get from VINE street pub off of 17th in Denver. Go Boulder!!

We happened to run into Mountain Sun after a big hike in the beautiful Rocky Mountain National Park. The restaurant we wanted to go was reserved by a private party the whole night, oh well...Mountain Sun is so vibrant with lots of young and hippie crowds. The decor is simple yet pleasant with lots of boutique textiles. The beers were so good! A lot of them are brewed in the pub. The falafel was just yum even for someone like me who is not a big fan. My Turkey cheese melt sandwich was also delicious. We had a full stomach after all, and happy...Boulder is great!

Went for lunch today, had an Annapura Amber beer, cup of Black Bean Chili and the Black Bean Burger for lunch today. All were very tasty. A bit confused about service for we had four different people at our table together. And we had to ask for the check to be totaled, and then weren't sure what to do with it when it was. We took it to them, didn't take away from the food nor the experience, just a bit questionable.

I love this place. This was the the first place I ate when I moved to Boulder. Chill atmosphere, great food and good beer. What more could you ask for? Some of the beer is available on nitro, which makes the beer extra smooth. I always enjoy coming to this place. Located on famous Pearl Street.

Mountain Sun = Second-best burgers in Boulder. That's saying a lot for a hippie joint. Sure, they've got a tempeh Reuben, as one might expect, and plenty of other hippie fare (and a perhaps surprising amount of Mexican food options), but they still know how to grill a piece of meat (all-natural, hormone-free beef, of course). Their house-made beers are great as well, and I've never had a bad meal, be it a happy hour taco, the burger, a salad, pasta or even said tempeh Reuben. Complaints: They don't have a TV. Not only that, they refuse to have a TV. Rather pretentious. I'm not looking to be inundated with televisions, but sometimes I just like to go to a neighborhood pub, sip a beer and zone out watching the tube. But overall, this is a minor complaint. I come here for food and to be with my friends, and I'll go to the Lazy Dog if I want to watch TV while I drink. Oh, another complaint. Get a freakin' credit card machine. It's 2007. Mountain Sun's cool factor in a nutshell: During the great blizzard of 2003, when the entire city had shut down, when police were ticketing people for driving their cars, I walked down Pearl Street (I lived downtown then) to see if anything was open. Everything was quiet and closed--except the Mountain Sun. The place was rocking. Not even a blizzard can stop these people. Rock on, Mountain Sun.

We ended up at both mountain sun and southern sun multiple times over the course of a week long visit. The food is plentiful and good, the beer is excellent and the employees seem to love their job, which makes me happy. The place is relaxed and there is always a young crowd hanging out, talking, laughing and playing games they discovered in the large stack of them on the bookshelf in the corner. I tend to gravitate toward browns and amber ales and both of those were excellent here.

Nothing against these guys. I drove about 30 minutes to eat lunch there due to the high ranking. I don't get it. It's a college town pub, basic decent food, kind of a short beer list but adequate. I'd eat there again if I happened to be in the neighborhood, but it isn't worth going out of you way.

Stopped in for some lunch on Saturday. Laid back atmosphere, friendly staff. Tried the following: - Monterey Chicken with guacamole, Jack cheese, lettuce, tomato, onion on Multi-Grain Oat w/ a side of tortilla chips ($8). It was ok. Probably should've gone with the baguette option instead of sandwiched between 2 slices of bread. - Basil Blue Cheeseburger with blue cheese crumbles and basil blended into a dressing, then poured on the burger and garnished with a fresh basil leaf ($7.75 + $1 to sub chips w/ fries). Ordered this medium well but it came out medium rare. The meat was pink and mushy. Sent it back. Fortunately the waiter was cool about it. Burger was redelivered as specified. The basil blue cheese dressing was too runny. It went everywhere, so I didn't get much on my burger. It also made my bun soggy. The bun is supposedly whole wheat, but it looked like white bread to me. Maybe they use white whole wheat flour? The fries were nice and hot. They seemed fresh cut and I liked that they left the skin on. - Junk Burger with bacon, Pepper Jack cheese, sautÃ©ed mushrooms and onions, roasted garlic mayo ($8.95). Had high hopes for this burger but it kind of just tasted like your average bacon cheeseburger. Overall, the food was mediocre. There wasn't anything particularly unique about the flavors. However, it's a nice, laid back place to come in and chill. The restrooms were a little bit gross though. Could've used a good clean up. Note that they are cash only.

OK, just keep in mind this is based from 100+ visits. The place rocks -- fantastic beer, brewed in-house, cheap fantastic beer, nice vibe, even a family vibe if you want to bring kidz, music at times (Sunday nights), the Southern Sun also, hippies, solid pub food, great happy hour prices on beer. A great place for dinner or an extended 4-6 hour hang with a rotating cast of friends dropping by. friendly and loose. Used to live in Boulder and this may be what I miss most in NYC. Sometimes there's a big wait but what are you going to do about that?? Go to Southern Sun in South Boulder or better yet go stuff your face at the Olive Garden in Louisville, if there is one there.

I was wandering around Pearl with one of my friends, and neither of us are from Boulder, so we decided to stop in. Their cheeseburgers are really good, not too big, not too small, cooked perfectly...I can't wait to go back for their beer, which I hear great things about! Happy hour sounds fantastic, I must add it to my Happy Hour list (not yet on Yelp).

Best burger & beer value in Boulder! They have Monday Burger Madness which is a cheeseburger, homemade fried and a pint of your choice for eight bucks. Super!

I've been here once, and I dont know if its a California thing, but happy hour at this place is really a HAPPY HOUR. I came with some friends, and 6 beers cost a little under $20! They offer some beers from nitrous, so they have the same foam consistency as guiness. The carbonation seems "smaller", and its sooo good. I would recommend this place to anyone to in boulder. Also, the wait staff is pretty rockin. We only came to grab a few drinks, but the waitress we has scored us some free fries. Pretty sweet deal.

Vacationing in CO, visiting family and having had a somewhat traumatic day (rear-ended in rental car, followed by an unrelated visit to the ER in Longmont with one of husbands family members) we decided to spend a little time on Pearl St. After a couple hours of browsing the stores and letting the kids run loose we thought we'd settle in for dinner and beer at the Mountain Sun. A word of caution, if you are allergic to Patchouli - or hippies for that matter - don't come here. ;-) Thankfully, living in the SF Bay Area, it felt like a little slice of home. F*ckin' hippies. The place was nice and loud - which was great since the kids were getting pretty cranky having waited at least 45 minutes for a table. The food was pretty good - I had a really fresh and delicious spinach salad - the kids had burgers and fries which were perfect. The beer, for the most part, was fantastic. We were really happy with our selections, with the exception of the Arctic Wheat, some bizarre minty concoction (i know this won some sort of medal - but folks - some flavors just don't belong in beer). The FY IPA was outstanding (OUTSTANDING!!!!!!) and was definitely the evening's winner. The service was slow and scattered (which I attribute to the fact that they were incredibly busy) - but the servers were really nice. We seemed to have several people waiting on us, but none really seemed to know what was going on - so when we got our last round of beer twice and the server realized someone had already brought it to us, she put the fresh beers on the table, looked at our still half-full glasses and said "Do you want to keep them (free of charge)?" We had probably already had way too much beer for one evening, but when someone offers you free FY IPA it would be a crime to say no. Ladies and gentlemen, that's what cabs are for.

Delicious burgers and loved their Raspberry Ale (and I don't usually like beer, so that's saying something). Had a great time playing yahtzee while waiting for our food in one of their booths. Loved the food, the staff, and the atmosphere. (for those of you with children, it was definitely family friendly) Well done, Mountain Sun!

Adena R.

The beers were great. Everyone at my table enjoyed their different brew. The food was great as well. Burgers all around and they didn't disappoint. We waited about 15 minutes, worth the wait. The oven wasn't working so we couldn't order the nachos but other then that we really enjoyed our lunch.

This small joint definitely has that hippie vibe; with the crazy psychedelic decor, board games to play while you wait and waiters with dreadlocks, but they were super friendly and the food was VERY good! I got the burger and fries and would highly recommend it. While it wasn't as good as Park Burger in downtown Denver, it was very juicy, well seasoned, and bursting with flavor. I definitely recommend checking this place out if you are anywhere near the Boulder area!

This is my favorite place in Boulder. The people are awesome and so is the beer and food. My favorite beer in the world is a tie between their Colorado Kind and Quinn's Golden.

Dude!! I've been all over the land in search of the best fries and have found peace of mind at Mountain Sun. They have amazing chalk art, wall murals, and cozy atmosphere. Best place to socialize, or get lost in a book, with a basket of fries.

Dave C.

This place sucks! The beer is vastly OVERRATED, I can think of at least a dozen microbrews that put this beer to shame. The food was just awful. Fries were not even close to cooked enough, just incredibly soggy. I think I've had better fast food burgers than the flavorless burger I had here, plus the bread was stale. The service was abhorrent. The servers were very rude, almost acting like their night was ruined because there were customers in the restaurant. To top it all off, I'm suspicious that one of them spit in my beer. If you are thinking of eating/drinking here, save yourself the trouble and go anywhere else on Pearl St (there are TONS of better options).

Dined here August 2009, I'm reminiscing. 3.5 stars actually. Fabulous place on Pearl Street Market to grab a beer and a great burger. This is a super good family spot and the tunes really enjoyable. It's a locals place, so go and enjoy you silly tourists but don't be in a hurry, okay? It's just so rude. Chill ......

Samantha Y.

They have an amazing beer selection with unlimited samples. The staff was very knowledgeable. Everyone from the bartender to the waiter to the manager was so friendly! I ordered a beer and the waiter brought me a sample of a similar one he thought I would like, so great! I made my own grilled cheese, had a salad, and a side of fries. All were delicious & fairly inexpensive! I would seriously move to Boulder just to go here regularly! I don't know if I had a few too many beers or what, but I left here so happy. PS. Cash only

Julie H.

Legendary local Boulder hangout. Amazing beers! Generous portions and low prices for food, sort of high for beer and wine, only accept cash or check. We go 1-3 times a week. Fabulous waitstaff, so helpful and friendly, our favorite restaurant by far.
(5)
S B.

I love this place. Even when it is busy, the servers will provide you with a beer while you wait. Great hippie ambiance. I always order the Annapurna Amber, and then it's on to the delicious menu. Whether it's an avocado grilled cheese sandwich, or Tim's blackened chicken quesadilla, the champagne vinaigrette steak salad, or just a regular cheeseburger- the food is excellent. The service is great, the beer is great, and the food is great. My only suggestion is to call ahead on busy days to get your name on the list for a table, or you may be waiting quite a while. Thank you mountain sun!
(5)
Margaret R.

The beer at this place is so good! I loved the Jah Mon Ginger Beer. They aren't shy with the ginger, and it was very refreshing to experience such an unusual flavor. I also had the opportunity to try the Date Night Burger. It had dates, goat cheese, and bacon. That flavor combination is completely unexpected and completely delicious! There is definitely a reason this place is busy all the time.

SOB the SOB burger is out of this world! Add in a blonde Belgium and their amazing fries and you will leave here happy as a hippie with a new bottle of patchouli!

D. W.

Wow...not sure where to even begin. I have lived in Boulder for 10+ years and go here at least once a week sometimes more. Don't miss Sunday night here when there is live music. I love how they have been experimenting and implementing more Belgian beer varieties. The staff is really helpful and cool and would be happy to give you tastings of all the beers to get you acquainted. Some don't miss beers are the java porter, vagabond IPA, Belgo-Java American-Belgo Coffee Porter, Fruitcake, Addiction Coffee Stout, and the famous Hop Vivant. Also, make sure to stop by in February because it is Stout month and during this month there are numerous stouts that are only available then including the Coconut Cream stout & Girl Scout Cookie Stout. Try all of them! Food wise, order the nachos because they are amazing and HUGE. I would also suggest the pollo asado burrito. I get the red and green chile because I love them both. The buffalo chicken sandwich is also tasty and so is the vegetarian black bean chili with tortilla chips. The Mountain Sun also has rotating daily specials which are usually pretty good and feature a daily wrap, soup, sandwich and salad. The date night burger with dates and goat cheese is a new menu addition that is delicious! Now get here and order a beer already! #BoulderOG #BoulderStaple #BoulderLocalRegular

I like the Mountain Sun for the great beer they brew. My favorite beer is Annapurma Amber, with a cheeseburger and fries. The beers definitely sneak up on you, so be aware and pace yourself or you will be taking a cab. And FYI, BRING CASH!!! Here's your warning, they don't except plastic. They DO have an ATM though. My only peeve about this place is how LOUD this place is. I can only imagine what this place sounds like with a live band going.

Katie B.

My boyfriend and I visited Boulder for the first time in mid-April. Mountain Sun was recommended to us by a friend of mine who lives in the area. I am so glad we took his advice and dropped by! We dropped in around 7pm on a Sunday evening, so the place was busy gearing up for Music Night. We had a thirty minute wait, but if we'd sat the common table we could have been seated much faster. The idea of communal eating is a little foreign to us, though, so we opted for a private table. We had all the free samples of beer that we wanted AND free french fries while we waited! Our actual meal was delicious as well. I can't remember what we ordered since it's been two months since our trip, but I remember leaving incredibly satisfied and excited about my next visit. I will definitely be back the next time I am in Boulder.

Samantha M.

Yum! I'm new to Boulder and stopped here for lunch the other day. I ended up choosing what HE suggested (Ciel Lumineaux) over my own picks. I had the Boom Boom sandwich, which is a marinated, cheesy portabella sandwich on focaccia bread with fresh mesclun mix. It was *really* good. I'll be back to try more beers!
(4)
Steve P.

Our first stop in Boulder and one of our favorites. Some really great beer and some of the most knowledgable wait staff I've encountered. Really like their philosophy towards the business as well as the food and beer quality. I'm a fan, and if we lived close by I'd be a regular!

The atmosphere is very cordial here. Don't be confused at the entrance. Just bee-line it to the back for an overview of their great beers with the uber friendly staff. I loved the biscuity English style IPA. Bring cash as they do not take credit cards, though as reflection of their good karma ways, you could just mail in what you owe later. The food isn't bad either.
(4)
Daniel E.

A very nice little pub serving very well made beers. The java porter is excellent, and definitely worth a stop in. The food is ok - we got a salad and soup, which was probably a mistake in a burger and sandwich joint. The guacamole serving size is pathetic - about 3 bits and your done. But the nachos were great, and a very good size.
(4)
Daniel H.

Really good beer and great burger. The junk burger was excellent. I'm on a hunt for the best burger in NYC and if this place was in NYC, it would be I'm top five. It was a bit noisy and a bit of a wait for a table but that didn't bother me so much because the staff were friendly And the beer and burger were so good.
(4)
Kristi C.

We went for dinner at around 9pm on a Wednesday night, and had a 20-minute wait, which ended up being less. There was some good and bad - here's the breakdown: Food: 2 stars We were pretty disappointed in our meals after hearing great things about this place. We both got sandwiches that were sub-par, and the fries were lukewarm and bland. I didn't even finish them, which is saying a lot. Apparently they are known for their burgers, which may have changed my rating had that been what we ordered. Service: 3 stars After being pleasantly surprised that the wait wasn't as long as anticipated, our server got the job done. Pretty standard. Tap beer selection: 4 stars My husband couldn't stop eyeing up the tapper wall. Atmosphere: 2 stars Liked the hippy causal vibe, but the flow of the place is a little awkward with a crammed waiting space at the bar in the back of the restaurant. And it was loud... very loud. So loud that it was difficult to hear my own voice at times. Can't imagine what it is like on the weekend. Overall, go for the beer, not the food.

Mountain Sun taught me to love beer after I turned 21. I used to drink anything but I saw the light at Mountain Sun. Now 4 years later, Mountain Sun is still my go to place for amazing beer and really good food. I always get the Tempeh Ruben which is amazing and can be made vegan by leaving off the cheese. The 1000 Island is vegan! The french fries are also some of the best I have had. Now to the beer. When I lived in Colorado, Stout Month was my favorite month of the year. Last night I had the Java Porter, the nitro Colorado Kind, and the Smoke Screen Porter. My life was complete. Upon my first sip of Java Porter I almost broke into tears because it was so good. It gets really busy here. You need to be aggressive to push your way up to the bar to get on the wait list. In the past I have walked in and just turned around and gone to Southern Sun since it was too crowded. The staff are awesome and knowledgeable. The art on the walls is amazing and makes this a beautiful space. The only thing I wish they had that they do not is Tabasco. They have Cholula but usually it does not do it for me. Otherwise, this is the perfect brew pub that I compair everything to.
(5)
Hollie W.

Great place. Beers are tasty and there are regular vegan options available. This location seemed a little less organized than Vine St. in Denver but it is also quite a bit smaller (and smaller places can just seem hectic when busy). A bit of a wait mid-afternoon on a Saturday so wear comfy shoes and order a beer while you wait for your table. Tempeh Reuben made vegan=D-lish!! CASH only. :)

This review is for the bar only, because we grabbed dinner elsewhere before we headed here. The place was packed so I consider that a good sign. Beers were terrific and the employees were super helpful. The bartenders knew their stuff. We got good descriptions of their beers and tastes to help us decide what to get. They were having Stout Month so we tried a few -- yum!
(4)
Rachael K.

Came back today to give it another shot and try more beer. We got a sampler of the beer (last time was pitchers) and tried a bunch of house beers (2 ipas, the mocha porter, a pale ale, a berry ale, and Colorado something). I enjoyed the beer more than last time when we only tried two, the beers are true to their names and don't try to be something that they aren't. I'm bumping them up to four stars because the entrees were fantastic and the beer was good, there just weren't any standouts that rivaled my favorites. Heads up: Get here on Saturday around 1 and you are Golden but come after 1:30 and you are likely to end up with a hefty wait.

Such an awesome introduction to Colorado. The vegan options were delicious. The beer was also sooooo good. And this from a beer non-enthusiast. I would definitely visit this place often if I lived here, and I'll certainly be back upon any subsequent visits.

Every time we have lunch in Boulder, this is our favorite restaurant. Their black bean burger, smothered in onions and mushrooms is as good as you'e good to get considering it's not beef. Also, best fries you can imagine, and the nicest wait staff.

Brian M.

Mountain Sun does a quality job all the way around. We stopped in on a busy Memorial Day weekend and they got our party of 5 seated within 15 minutes. The entire staff is on the whole quite pleasant and we thought our hostess and server were definitely above average. The Belgian Trippel, Jah Mon ginger beer, and blackberry wheat were quite tasty an spot on style wise, while the Rye IPA and some of the stouts were good but not great. I'd recommend trying the Date Night burger, which has bacon, goat cheese, and a date purÃ©e and is fantastic. Probably the most unique item in the menu, and with a better bun would have qualified as one of the best I've ever had. Pricing is very good, and it makes a great starting point for a Pearl Street cruise.

Danielle G.

At this point I've been to both Mountain Sun and Souther Sun. Both have awesome food and beer for a fair price. I love the Stouts and Porters on tap and services has always been stellar.

Build your own grilled cheese. Great basil blue cheeseburger. Best food and beer I had while in Boulder.

Adam J.

I'll admit they have good beer and comfort food here, but I don't think it's worth it to deal with the crowd, noise, and cash-only policy. If you really having a craving for their beer head to Southern Sun, twice as big with half the crowd.
(2)
Harry S.

They burger patties have become thinner and less flavorful. The 20something male clientele only knows two words and they start with F and S. There is no accountability for customer service because all servers wait all tables and there is no proper manager in sight. The beer is still pretty good, but I'm no longer sure sure that it's worth putting up with the rest of the 'experience'.
(3)
Dillon S.

I LOVE MOUNTAIN SUN! I came here again in November when my sister came out from New York for Thanksgiving. We went to Mountain Sun and there was a huge wait, but stuck it out. The girl seating us kept updating, apologizing for the delay, and letting us in on her strategy for getting us seated for as soon as possible. We celebrated my sister's birthday and the staff totally made her feel loved! We got several free items, and one of the servers had the whole restaurant yell "Happy Birthday Kate, you sure are great!" It was so cute. My sister was so surprised/happy that she cried :) Perfect place to show a New Yorker the Boulder cheer. If you don't mind a little crowd sometime, Mountain Sun is a great spot downtown. If you want the same vibe but fewer people, hit up Southern Sun! Its there sister restaurant in South Boulder and is awesome as well.
(5)
Sara P.

This place is a rollickin' good time. I liked several things about Mountain Sun. First, they make a ton of beers, and they are good. I had both the english-style and american-style IPAs. They were both unique and very tasty. I had the blue cheese basil burger, and it was cooked perfectly, the sauce was amazing, and they somehow had tasty tomatoes at the end of December. I love their service model here, where it seems that everyone wants to make sure that the customers are taken care of, and the servers and laid back and friendly. I'm so glad I ate and drank here!

Back to one star again. There was an amazing sounding beer on the menu, but they were out of it and had been for a while. If you are out of it TAKE IT OFF THE MENU.

So as I mentioned before in previous reviews I have been on an extensive tour of Colorado breweries this summer. Mainly along the Front Range. Mountain Sun caught my eye when I was reading the best of Boulder issue from Boulder Weekly. This instantly beckoned to me to go try it. I am very glad that I did! I had a wonderful Blackberry beer which was to die for! I could really taste the berry in it unlike other breweries that I have been to that claim that you should be able to taste a berry flavor in the beer but it fails to do so. Steven got a ginger beer which was also awesome! We went ahead and proceeded to order our meal. We both decided to get some grilled cheese sandwiches which turned out to be an awesome choice! You can pick from various ingredients which are all so fresh the sandwich will knock your socks off! We decided to get salads instead of chips with our meal which I don't know if that was a slick up sale on the waitress's part or a bonifide substitute. On the bill we were charged extra for the salads and also overcharged because the guy that made our bill misread what the waitress wrote. He corrected the bill instantly but the salads we thought were a bonifide charge even though it made the meal more expensive than what we thought it should have been. Despite the error with the bill our meal at Mountain Sun(which did not result in any deductions on stars... surprise!) was awesome and of course you have got to try their beers if you don't eat anything. They have a sister location named Southern Sun, also in Boulder which makes the awesome food and drink even more accessible!

C. M. H.

Great selection of local brewed beer. The service was great and food really good. B/c there was a wait when we got there, we went to the bar, where the bartender let us sample the beer before we ordered; he was real nice. Lots of table for four, so be cautious with large groups when it's crowded.

Scot P.

I've been a fan of Mountain Sun for more than 10 years. It's a favorite for some of the best burgers in Boulder and with grass fed local beef it's even better. My favorite is the junk burger but look to the specials for a unique burger experience. Add on top of that it's also a brew pub. My favorite, the Illusion Dweller IPA. Hard to believe they can brew beer in this small space. The Pearl street location is small but very friendly. They don't accept credit cards, which is the only reason I don't give them 5 stars, so remember to bring cash. The cash machine in the back charges you an extra $1 on top of what ever your bank will charge.

I absolutely love this place. I don't make it out to RMNP as much as I'd like anymore, but when I do...Mountain Sun is a place I am sure to visit on my way from DEN to Estes Park. During my last trip, we stopped in and sampled a few beers (which were all enjoyable) and had a pint or two. We left with a growler of Colorado Kind and FYIPA. Note: the "growlers" are large Ball Mason jars and leave a bit to be desired for any trips greater than around the corner. I enjoy the location, the relaxed atmosphere and the friendly people. Cheers!

I loved Mountain Sun Pub & Brewery so much I went there twice during my visit. Nice casual environment. I loved the colorful murals painted all over the walls. Mountain Sun has an excellent selection of beers, especially a good variety of stouts. For a change, I also tried their blackberry wheat beer, a lighter beer that was also very good, although I maintain my preference for stouts and other dark beers. This place offers some great pub grub. I ordered the mushroom onion Swiss burger, and it was excellent. If you are in Boulder and looking for a place that serves great beer and food, while dishing out some local color, then you must give Mountain Sun Pub & Brewery a try.

Spicy Pollo Asada Burrito was the best burrito I have had outside of New Mexico. Great beer and cool atmosphere

A lovely spot on Pearl (less manicured and trendy than its neighbors, which is a good thing!), with a fresh appealing menu and an extensive, enticing beer list. I've been listening to my little brother and his wife sing Mountain Sun's praises for a while now, and was happy to see why on my Boulder visit. Since I'm an IPA girl, I was happy to see three of their own (not all on tap at once) right up front on the list. The F.Y.I.P.A. was bright with a hint of citrus depth, and well-balanced enough that even folks who aren't hopheads should be able to appreciate this great beer. (Personally, I haven't yet met an IPA that was too hoppy to love, although I've tasted plenty that weren't hoppy enough to be worth it!) As other reviewers note, they always have a tap or two on nitro, which is a great thing to see at a brewery and I hope to run across more frequently. Another plus to Mountain Sun: you can order tasters, and for a larger drink, you can get your beer in an 8, 16, or 24 ounce pour. I'm always glad when I can have a smaller drink. Then I can have more of them! The food was good as well; chips were upscale root-vegetable/taro style, a nice touch. Very friendly service, and a nice laid-back, beer-loving yet family-friendly atmosphere (there's a kid's menu with good stuff). If there was a spot like this in Seattle, I'd be there all the time. So maybe it's good that there isn't....

Suds, buds, and great service. Everything here was most definately laid back but truly on point. Everything from timing of food, refills and questions being asked were excellent. The Asst Mngr whose name I didn't get to write down before jetting out even stopped by our table and made sure that our experience was wonderful. We had an array of servers but the trainee and trainer who initally served us were also wonderful and friendly! I look forward to the specials on my return! Thanks again!

My friend sent me a text that said go to mountain sun brewery and get a colorado be kind ale. that is exactly what I did. repeatedly. i think the be kind ale on nitro was my favorite of the two versions. the food was good too. far better than a lot of bar food that is out there these days. colorado be kind on nitro. do it.

OMG 5 STARS!!! Rarely does a place get 5 stars but this one did. We visited on the Friday night before the first CU football game so we expected to wait. We went to the bar in the meantime and all the bartenders were very friendly, giving us tastes of their brews. We shared the quesadillas and the nachos. They were better than most Mexican places we have been. The nachos were gigantic and piled high with ingredients. We cleaned the plate. We will go back when we are in town again.

Food was EXCELLENT! And the beer was wonderful as well! The service was great, and the atmosphere was really nice! However-- we were a little overwhelmed by the service-- they are very chatty people! My husband and I are pretty introverted, so it was slightly uncomfortable. However-- some of you might not mind that at all. Give this place a try, their food and beer is excellent.

Alex B.

I haven't tried the food here, but the beer is excellent and the bartenders are friendly and helpful. I told them I liked IPAs and hoppy beer in general, and was immediately given 4 samples, no questions asked. I decided on the XXX Pale Ale, and was not disappointed. As much as I like the place, there are a couple gotchas you should know about: (1) They *only take cash*, so be sure to have enough on hand. (2) This place is really popular, so it can get loud, and finding a table is a challenge.

I first got to know Mountain Sun a decade ago when introduced by a very good friend (my thanks, Rich G.). It was a great experience, but I had given most of the credit to Rich. Opportunity knocked and I was able to return for lunch on a mental health day I had built into a business trip. Not just good company a decade ago - this visit was great: wonderful service, great recommendations, a savory spicy sandwich, and a sampling of some great beer. Well worth the visit for lunch on Pearl Street.

Cash only! I had the tempeh Reuben (and while not as satisfying as a real reuben, it was very tasty). Mom had the 1/2 sandwich & soup and she was very happy with that. Spouse had the Quinoa salad special and enjoyed it too. Beer was very tasty. Service was good. It was a pleasant surprise because I was expecting a place on the Pearl street mall, but this is a block or two off the mall.

Great beer made on premise, excellent kitchen, fantastic staff, fun patrons. Did I miss something? I got a tip from Boulder Music to try the place, and then we happened to walk by it while hungry...bingo! Glad we did. Wait was long, but walking around the block is fun so we passed the time quickly. FYIPA was fantastic. The staff is so friendly, warm and accomidating. Everyone...not just one of them. wow. Kitchen was very slow (my only complaint), but food was great. Fantastic burger and excellent fresh cut fries. Yum yum! Oh, and the FYIPA.... It's kind of funny how everyone waiting around is crowded up by the bar. It's cramped and very loud, but I also found it strangly appealing.

Went on vacation this weekend up to Denver and had the opportunity to visit Boulder. I love this college town. I wish I would have been up here as an undergrad with this many in shape and hot students. Seeing as I had my girlfriend with me, it was not polite to look hahaha. I've been to Boulder before and had lunch at BJ's. I remember that I wasn't to impressed with their beer or the food and was looking for another good brew pub. I did some yelping (thanks guys!) and found this jem just off the mall and out of the craziness. We stepped in and while it was busy, the staff immediately took our names and invited us to have a drink at the bar while we waited. I looked through the list of brews and decided on the Raspberry Wheat. I've been in the mood for wheat's and golden ale's etc for the last month or so because of the warm weather. It was delicious with just a hint of Raspberry. I would have actually enjoyed more. My girlfriend and I ordered a pitcher and we got to see all the action behind the bar and in the kitchen. A table opened up and we sat down starving. I usually don't ding reviews on the service, but we waited for another 10-15mins before anyone came by to check on us. It wasn't that big of a deal because we had beer, but we were both ready to destroy some lunch. Our server was cool and helped out with recommendations and we got another round of the ginger beer and golden ale. I got the American fields salad which was a bit different from my usual fare and my gf got a cup of chili and an avocado sandwich. The food arrived and my salad was a bit of a disappointment. I've been on a salad kick lately as well and this was just a bunch of shit tossed together with greens called a salad. I'm being picky I know, but there was waaaaaaaaay to much salad, not enough of the fun stuff (strawberries, blue berries, almonds, red onions) and the dressing was on the side. Some people like that, but I hate it. Especially with greens overflowing my plate. It's an exercise in dexterity not to push anything off your plate while trying to mix it together. This salad had a lot of promise but the execution was lacking. I should have gone with the spicy pollo burrito. My gf's sandwich looked good and I stole a bit of her chili. OMG it was delicious. I then had to order a cup of chili too! hahaha it was the best part of my lunch. Overall, I really liked this place. It was really chill, everyone that I talked with was mad cool and the beer was great. I just had a sub par salad and it took us a little while to get some food. I would come here again and would recommend it over most of the restaurants on Pearl Street.

Only reason I'm not giving this 5 stars is because we didn't eat here so I'm not sure how the food is. The beer, however, is delicious. We stumbled upon this place this past weekend during our day trip to Boulder. Worth checking out. I'd recommend their beer flights - 6 samples of any beer on tap. Our waitress Natalie was friendly and knowledgeable about the beer.

We stopped in this brew pub recently during a short stint to Boulder, in which we managed to fit in stops at six different breweries. Mountain Sun was fantastic- and easily the busiest brew pub we visited. The staff were laid back and friendly, and they treated us more like we were visitors in their own home rather than customers equal to a sales percentage and tip. We were offered beers to sip while we waited for our table, and once seated, had a hard time choosing from all the delicious options on their menu- beer and food both. The service throughout our meal was as attentive as you could want, but never obtrusive or overly eager. This place was great- bottom to top.

We went to the Mountain Sun for lunch yesterday... and as always, the food was impressive and the beer plentiful. I settled for raspberry iced tea yesterday while pseudo hubby enjoyed a Kind beer and a Crippler (Kind & the IPA mixed) ... very potent. I like that you can get beers in 8 oz sizes also... this makes it easier for people like me to try multiple beers without getting full from one single pint glass. I had the special sandwich yesterday - the Boom Boom - grilled & marinated portabello mushrooms, roasted red peppers, provolone, pesto mayo, and a little lettuce sandwiched between lightly toasted ciabatta bread. I liked that the bread was light and not too dense and filling for the lightness of the sandwich. The grilled peppers and pesto mayo were really fantastic with the mushrooms. The plate was piled with freshly made fries and a crispy pickle spear. The man ordered the reuben - a tempeh reuben - it was pretty good too, although I don't know if I'd order it again. I like tempeh, but when it comes to a reuben, sometimes you need the real meat. This was a very good alternative though, complete with saurkraut and tasty rye bread. We showed up at about 1:30 on Sunday, which was a good time... the lunch crowd was just winding down and we waited at the bar until a table was ready. There was a wide mix of people and a lot of kids enjoying time with their families while playing some of the complimentary board games. You just can't beat the Mountain Sun.

I've been a fan of Mountain Sun for many years...the service is top notch with a well informed and friendly staff....the food and sandwiches are delicious. Each beer is a strong representation of it's style....I really enjoy the times that the brewers go above and beyond. No credit cards are accepted but they have an ATM in the back you can draw money from...if bored you can always grab one of the board games available and see if you can rustle up a game with a nearby table. Overall...a great job and a place I always feel welcome.

Despite the fact that I almost always read and refer to reviews, I rarely, if ever, write them. I expect that someone else will take their precious time to comment on the average food, average service, and average experience... Mountain Sun Pub & Brewery was ANYTHING BUT AVERAGE! Our experience began about 4 blocks away where we caught the first scent of boiling malts and steeping hops. By the time we walked the half mile to the restaurant my senses were in full blown, blissful overload. Walking through the door of a brewery I expected the assault of TV's, loud drinking and raucous laughter, but was pleasantly surprised to find a busy, but peacefully quaint "cafe" style restaurant. We were immediately greeted by a smiling, and sincerely warm and friendly member of the staff, who apologized for the short wait. He eased the pain of that sting by immediately taking us back to the bar where we were offered what amounted to roughly a 6 pack of free tasters of their home brewed beers. Being a home brewer, I appreciate the heart and soul that goes into a finely crafted beer but this was a truly an amazing experience. Not only were the beers, ALL of them, amazing, there were no less than 4 of the staff bringing us samples as we waited. It was like they were sharing their favorites with us and wanted to make sure we had the opportunity to try them all before we had to settle on just one. As if were were not already won over, their eagerness and warmth to share with us was endearing, and showed what an amazing pride and joy they all had in their place. Oh yeah...there was food there too!!! Of course, when looking for a brewery you want a burger to go with it...but you never expect that you can have your brew AND a healthy meal!? The menu was beautifully pub-like, with a healthy and wholesome slant...burgers with fresh ingredients and whole grains, salads and sandwiches. My wife and I both had burgers and salads to go with our awesome beers; I had their JalapeÃ±o burger and the wife had their Cheeseburger with Pepperjack. In a society burdened with the notion of quantity over quality the size of the meal was almost laughably meager, but since I was paying a meager price for the meal I decided it wasn't worth complaining about. Little did I know that truly amazing food and quality doesn't require obscenely large portions, and we were amazed to find that halfway through the meal we were already blissfully full. It was as if some intangible, ethereal ingredient, passion perhaps, had supplemented the smaller portions to insure we walked away complete. Of course we finished the burgers anyway, but due to the quality of the food we walked away conscience intact. ALL of the above qualities, combined with the wonderfully pleasant philosophy of the pub, one of employee ownership and integrity, made for something better than a great dining experience...it made for a taste of community and comraderie where we felt like we got to share in the success of the entire brewery! This is one of those places you not only visit again, you hope to call home. I cannot wait until we get to go back to "our" pub!!!

My ex-girlfriend's friends used to love this place, so we always wound up going there for dinner. I've never had any food there I particularly enjoyed (nothing horrible though). That being said, I don't think any of their beers are all that good either.

I used to come here when this was the only non-smoking place in Boulder many many moons ago. Way before the parking garage was there which is now across the street. I also saw Yonder Mountain here one night after the garage was built, and after the small show, we followed the band to the top of the parking garage.We danced with the band playing acoustic on top of the garage until the police came and asked us to leave the garage peacefully. Those were the days I tell ya... Decent food, awesome beers-my favorite is the Java Porter. Inconsistent service. Sometimes excellent, sometimes completely LAME. have worn the shirt all over the globe-got most comments in New Zealand-people wanted to buy the shirt off my back! I can't imagine visiting either of the other locations, as there is only the original for me!!

This is a cute nice little brew/eatery. Came here out of a chance just walking by. The food was above decent bar food and the beer was good too. everyone found something they liked. Nachos are HUGE, split that between 4 and a couple other things too. I wouldn't go here for dinner but a lunch or snack would be perfect.

Hailey B.

I am giving this 4 stars instead of 5 (see my review of Southern Sun) ONLY because of the location. Mountain Sun is a bit too claustrophobic and dark (and no outside seating) for my taste. Menu is the same as S.Sun and waiters are just as awesome. Parking and noise level on the other hand, not as awesome...

After our rigorous hike on the Chautauqua trail (one that was cut short due to the ailment in my fathers knee) we were all famished and needed to replenish our bodies. One of our party members suggested we stop by pearl street and search for a restaurant. After a long and dreary search we stumbled upon a restaurant called "Mountain Sun." Indifferent about our groups decision I reluctantly joined them..... And I must say I was thoroughly pleased. I ordered a pollo asado burrito and after the first bite the spiciness of the burrito and the aroma of marijuana coming from the hippies of boulder mixed perfectly. I have to say that I felt one with the "Mountain Sun."

Who said you can't pretend to be in college again... woah this place made me feel a little old. I have been out of school 4.5 years now and visited Boulder on a work trip. Grabbed dinner here after arriving from DIA pretty late one night. Great spot for a good burger. Thinking I would just grab a beer and a burger at the bar... was a little surprised when I saw that there was no bar area. I sat down and chatted with some nice college kids playing scrabble! Regardless of feeling a bit old and grabbing a burger solo on a work trip... the food was fantastic! Fresh and organic! Very Boulderesk! Recommend this spot for lunch or dinner! Cheap and excellent! Plus a great location on Pearl Street!

As a note, this review is just for the beer. Stopped in to give the brews a try, and was a bit surprised at how small the joint is. You can enjoy a brew, but you have to stand at a bar that serves as the staging area for the waiters. They were nice enough to give us a table after it settled down, and the service was great, bringing us water even though we weren't ordering anything else. If you want to just get a drink, this may not be the place. The food looked good though, and I look forward to going there when hungry. The beer was tasty, with their doppelbock with their blonde being very good. I'll have to try some of the darker stuff next time (when it's cooler out).

Pretty tasty! Lots of interesting clientele to watch - beer was good, not the best i've tasted but not bad. Had the veggie burger - pretty standard, nothing to write home about. Tried some veggie chili - very tasty. Def get this. My friend had the grilled cheese with bacon and pesto - good but a little greasy. 4 stars - cash only.
