As far as the food goes, the french fries are exceptional! Get them with cheese on top you will not regret it. The hamburger was a good hamburger, but it was not as bodacious as I get expected by the description. But it was good. The staff was extremely accommodating and the crowd was great. The environment here is really nice for a date or for family. It's great for small, gatherings or large gatherings. I really enjoyed the vibe and I really enjoyed the hospitality. But here's where it gets Jenkee. I ordered a flight of beer. I ordered six. But only five came out and I was told they were out. However, the sixth came out after I started the flight. Not a big deal. But I had already tasted the entire flight in order. Then there was the flavor of each beer. I'll take it one by one. The Irish stout had a weird back flavor kind of like a chemical flavor not a natural flavor. The blackberry wheat was alright. I've had better Berry Wheat beers. But it's drinkable. Unlike its name, the Colorado Kind Ale was extremely confronting in its initial flavor. I think at the time of drinking it I said it was extremely abrasive. I don't think I even finished that one. The Spanish holiday sangria was also drinkable, but not exceptional. It was oddly bitter. And I love stouts. But the coconut cream stout tasted burnt. The best one was the Soul Flower Saison in my opinion. It's a little rich it's full bodied, and it feels like a treat. Well, I did not try every beer. And there may be some real golden award winning phenomenal brews at this brewery. But I did not find them on my flight. I think pretty much everything else was IPAs. If you go know that you will be well taken care of. Absolutely get the french fries. They are a super treat. read more

Opportunity to Improve. Upfront was told parties over 8 have an automatic 20% tip added. I stated the service should warrant the tip. I was assured it would. It didn't. We were not offered refills on our waters until we were almost done with our meals. We asked for ranch dressing as we were served, it never came. We had to go to the bar and ask for some. We did discuss with manager. We allowed the tip to remain. Like I said, these are opportunities to improve. read more

Came here after a long day and it was a great way to end the night. They are cash and check only! The service here was great! Our server was very friendly and attentive. We ordered one of their specials - A burger with apple jam and brie, and I think there was arugula. It was so good! Their beef is something else, the menu states that the beef they use are vegetarian fed Colorado beef with no steroids or antibiotics. The quality came through and the beef was spectacular! It was cooked to medium which is my ideal preference and it was so juicy. I loved the combo with the brie, apple jam and arugula! My favorite meal in Boulder! Their burgers all come with fries, and they were nice, soft but crispy at the same time. They also have a huge variety of beers and you can sample them if you like. I would definitely come back here! It's great vibes and good food and drank! read more

There's such a cool vibe to this spot! Normally I'd be irritated with a restaurant being cash only, but the "karma" policy of trusting others to mail-in a check later-on is awesome (there is an ATM for those who don't have cash and are able to pay during their visit). My bison burger was everything! I'd order it again and again. You could taste the freshness of the bison and it was cooked so that the meat melts in your mouth. It had the addictive quality of a fast food burger, but the freshness of fine dining -- who wouldn't want that?! The servers all share tips, so the entire waitressing staff is willing to help and checked-in regularly. I had a beer which was good (nothing extra special) but we were also given a free margarita which was made by the bartender-in-training. read more

Nothing but positive things to say about this place. The staff is friendly, I was there right at noon but it wasn't swamped (and they had the a/c cranked up when it was 90 degrees outside), my burger tasted delicious, and the fries were heaven sent. Note that it's CASH ONLY, though the ATM in the back only charges a $1 fee (in addition to whatever your bank charges). It's not "gourmet," but I'll never turn up my nose at a well made burger with delicious fries. Prices were also quite reasonable, in my opinion. read more

Went to Mountain Sun with a friend after a hike in Boulder and it fulfilled all my needs - a crisp beer and delicious bite to eat. The menu has options everyone including a great variety of beer; they offer free tasters if you're unsure which one you might fancy. The staff was extremely friendly. The restaurant isn't overly large but there was not a wait when I went. They have indoor and outdoor seating - I recommend outdoor as it is in the heart of Boulder and who doesn't love a good patio beer? They do not accept credit cards so you have to pay with cash or check, but there is an ATM inside. They also offer the option to take the check home and send $ after the fact - they believe in humanity. read more

The service was good and the burgers and beer were solid. Fries were oddly a little grey. Sorry, but $62 for two burgers, two beers, and two fries is wild to me. Charging extra for fries on an $18 burger is already wild to me. Also, having to withdraw cash from an ATM (credit cards not accepted) is a poor experience. I'm very surprised this place is reviewed as highly as it is. read more

Stopped in here after a hike -- Mountain Sun is more of a Restaurant than a brewery. Every table was full around noon on the weekend, but the tables turn fairly quickly. Service was exceptional by the team of waitresses and waiters constantly moving through the dining area. Food was alright. The guacamole was a bit bland, though. Good selection of beers -- all quenched thrust after a nice day hiking. read more

What a great college town eatery. The service is fantastic- 5 stars. Great conversation and friendly staff all around. The beer - 5 stars. All made in house! Casual and comfortable dining with tables and booths. Family friendly. Great menu with lot of great sounding options. I went with the grilled Reuben special and it was OK at best. Cheese fries were pretty good. I would definitely return but would hope for a better food experience. Cash only, team service and shared tips. read more

After an exhausting but fulfilling day of picking out a Christmas tree, my family and I were ready for a hearty meal. Mountain Sun seemed like a great choice halfway through the drive home, and we got the last large group table available. There were 7 of us total. Customer service is unrivaled. I'd come back just for the positive (Boulder) culture and vibes. For food, I had the S.O.B. Burger (bacon, Cajun seasoning, roasted hatch chilies, jalapeños, pepper jack cheese, lettuce, tomato, onion) which was quite tasty. I thought the fries were overdone and undersalted, not enough to send them back, per their promise. Everyone else seemed to enjoy their food too, including the kids who can be picky eaters. We had to park on the street a few blocks away, which is typical for Pearl St in Boulder. There was some sort of holiday parade getting ready, making it a more magical experience. Love watching the crowds around this part of town. Would especially want to visit Mountain Sun when the weather is warmer so I can enjoy beers on their front patio! read more

Amazing food and great service! We had the steak sandwich and nachos. The steak sandwich was awesome! Probably the best steak sandwich I've ever had. It had great flavor and the bread was perfect. Also the fries were awesome. Would go back for the steak sandwich. The nachos were also great but were so big and were too much for two people. If you have a group of 4-6 the nachos are good as a good sized appetizer and won't feel repetitive, but they were really awesome, the salsa and chips were great. The service was friendly and quick. Warning that they only accept check or cash but there is an atm in the back of the store. The bathroom and restaurant was clean and sanitary. Will be back for more sandwiches and fun atmosphere. read more

The date night burger was very good. Perfectly medium, crunchy slaw and apple. Fries are mid. It's nice that everyone does every job but that also means there were 4 people working with us. Someone to take our order, someone to drop the beer, someone else to drop the food and another person to drop the check. The beer was wonderful. They have a happy hour from noon to 5:00 pm daily. We already ordered when we noticed. Just like another neighborhood bar. Nothing fancy, nothing exciting, gets the job done when you're hungry. Burgers were $17+ read more

One of the most famous breweries in Boulder and for a good reason ! we had a 30 minute wait before we were seated because they only had one big table to accommodate our big group , however once seated the service was prompt . The first round of drinks and samplers were ordered and they came out pretty fast. The place was jampacked with patrons and the staff was on top of their game despite being swamped .The beer selection is exhaustive and offers a lot . We all got a sperate entrée and some shared munchies for the table . The food is mostly burgers and sandwiches with an occasional salad thrown in .. so don't expect healthy fare . Having said that the food indeed is pretty delicious and everyone seemed to enjoy what they ordered . They only take cash which they informed us only when we got the bill . I believe this information should be shared before you seat people because not everyone carries cash these days . We had a big party and naturally the bill was a lot which somehow we were able to pay for in cash but it sure could have been an issue if the bill was just slightly more . Apart from that I think the place was great and a fun hangout . read more

Hit this place up and had a great experience. Last time I was here had to have been a year ago or more but I stopped by yesterday with my parents. They loved the food so much my mom bought a t shirt. The beers here are always spot on, and the service is good too. Really no way to complain about mountain sun at all! FYI they are cash and check only! They do have an ATM read more

Fair warning, this place is CASH ONLY, so make sure to bring some so that you're not scrambling trying to figure out whether you brought your debit card or not. Came here after doing a hike nearby, and this place was solid. We ordered: * Elote - 8/10: I wish the corn was broken apart, but the cheese sauce was so delicious, pro-tip, dip the fries in em * Pub's famous fries - 6/10: I thought the fries would be more unique since they were prefix'd with "Pub's famous", but they were a solid pick if you want fries * Bison burger - 9/10: surprisingly very good though a bit smaller than I expected * Burrito - 8/10: absolutely enormous, about the size of a small baby The service was very friendly and you get to taste test the beers on tap in these small glasses if you want. read more

We stopped in after a hike and had a great time. We got a plate of fries and I had a burger (forget which one, but it was good) and wheat beer. The atmosphere is laid back and there's a relaxing vibe to it all. The service was fine, but note that they only take cash (no fear, there's an ATM nearby). read more

Honestly, I don't get why people think this place is so great. First, know before you go that they don't take credit cards, so if you don't happen to have cash or check on you (and who does these days?!?) they'll direct you to their ATM in the back. They'll promote the $1 service charge, which of course doesn't include whatever your own bank will charge you. When we arrived, there was about a 15 min wait, but you can't wait by the front. Instead, they'll direct you back to the bar where the bartenders try their sales job on you. When we got to our table and ordered, two of us got burgers and two got the roast beef sandwich. All looked good in Yelp pics, but all were rather small when they arrived. My medium burger was kind of still bleeding. It tasted good, but was maybe 1/4 lb patty cooked. I easily could've used more. Fries, which cost an extra $2.50, were salty, limp, and not great. I liked the chips (which only came because they forgot to sub the fries on two of our plates) better than the fries, but they were also really salty. Anything extra you want on your burger, including condiments, costs extra, so be prepared for the total to add up. The roast beef sandwiches were good, until the chewy parts were found, then not so good. All in all, kind of a more stressful meal than it was worth. Will likely just try someplace else next time. read more

Great music and immediate service. Came to visit Boulder and decided to stop in. We were quickly greeted and found a table. They let you sample their beers before you order. We had the blackberry wheat. It was very tasty. We ordered the Junk Burger and SOB Burger which were good. I was a little disappointed with the SOB burger since it was not Spicy at all. The chipotle ranch dressing was spicier than the burger. You can substitute the chips it comes with for fries at $2.50. The fries and chips were pretty good but the chips needed a dipping sauce. If you're in Boulder it's worth a try. read more

There were so many good lunch places to choose from during our visit to Boulder, but after much evaluation we settled on this one. We got a great vibe from the staff as soon as we walked in. We were also a bit surprised when we were given a basket of French fries as a free starter. Very unique, but we loved it...and they were yummy! We tried a few things off of the menu - the southwest chicken sandwich, buffalo chicken sandwich and the quesadilla- they were all very good! One other important thing to note - they only accept cash or check. read more

I've not been to the Boulder one, but the one in Longmont is always spot on. Great service an consistently great food, unique choices including choices for vegan and vegetarians. Their chocking wings are remarkable, and I'm no typically a wings person. The pub they had in Denver was just as good, so I have no reason to think that the Boulder one would be any less fantastic. Each one has hand painted detailing, and is charming and comfortable. Highly recommend. read more

Really really good food, friendly service, exactly the vibe you want after a 20 + mile back packing trip. The only knock here is the receipt, hard to tell who got what and they only take cash-- so not super great for large parties and groups overall which is bummer since brew pubs tend in that direction. Aside from the inconvenient payment model-- the food really is superb. Food wise if you come here- 10/10 recommend the junk burger place which was to die for with any of their IPAs. read more

Go to this brewery!! Bring cash or use their atm for payment. Our server was excellent and friendly. Our beer was delicious! The food was AWESOME. We were expecting the food to be just fine because it's a brewery but wow were we mistaken! The vibes were a mix of hippie, cool, and cozy. We cannot wait to come back! read more

The family stopped in for lunch on a Saturday during our vacation to Colorado. This is a place that people will either love or hate. Let me explain how things work in the place then talk about the food. Everyone who works here does every job. That means Mon Joe is the manager, then Tue he works in the back, then Wed he is a waiter, etc. So you could have VERY mixed service. The place was also very loud. Sat at lunch was very busy so I might suggest an off time slot. Also the place is cash only. The good news is the food and beer. The Megaton Imperial Stout was one of the best beers I had on our trip. The Speakeasy Steak Sandwich was a hit as were the fries and drippy burgers. 5 stars if you are willing to chance the service. ;) read more

Great food, excellent fries, and really good local beer. They'll let you taste as many as you'd like before ordering which is fantastic, I loved the Kolsch. Lovely space. Service is terrible. I'm not sure what their issue is, it's the worst service I've experienced in a long time. We had 4 different servers during our meal, yet somehow they never seemed to be around. I asked my server for a spoon, they said absolutely, then never came back to the table. It wasn't even that busy either, just abysmal service. Sadly we left a pretty small tip, which I hate to do, but clearly they need the feedback. If you have the time, it's still worth it, as long as you're ready to wait an hour to get anything to the table and you won't need a single accommodation. read more

Great pub to unwind after anything! I came here after a hike to get beer and enjoyed everything so much. I got the Swiss Mushroom burger medium rare with a side salad. The burger was just perfectly juicy and seasoned well, each bite was amazing! The salad was also super refreshing. My friend got kettle chips and really enjoyed his as well. Another amazing part of this pub is the beer! There are so many really good choices and they even let you sample them! I was almost full from sampling but still chugged down a pint. Everything was good and I will definitely come back! Reminder it's cash only! But they also have an atm inside. read more

Fun stop after a big hike. The service was very good (they tag team it - but all 3 were skilled). Great variety of beers, and free samples (I tried 5 different IPAs!). The chicken quesadillas were good, but my wife really disliked the tomato bisque (it was essentially marinara...). read more

The burger I had was delicious, though the fries were a little lackluster. At the time we arrived there was not enough staff and it took forever for us to see a waiter, though they were friendly. The beer was not very good and we tried 6 different kinds before deciding against it (though I admit I'm not much into beers). Many of the beers were surprisingly sour. Another thing I did not like is that because of the sugar tax, they do not refill sodas and a soda is 1.50 more than a diet soda which seemed ridiculous considering the sugar tax would likely only charge the distributor 30 cents max. Overall would not recommend. read more

FREE BEER! I visited Boulder to kill time before late flight out of Denver. Some dude was walking around offering "free beer" cards. Pretty easy sale. So I took my free beer card and headed over. The staff at MSPB were all unfailingly pleasant and attentive. A+ for service. I ordered a hazy IPA, which was good, and an impossible burger, which was fine. One complaint, and it's not major, but still. When I ordered my burger, the waitperson said "do you want chips or fries," with a downward inflection at the end, implying that it's included. Then, when I got the bill, the fries were extra. Hmm... The free beer was nice, but if something's not included with a dish, the inflection needs to go up: "chips or fries?" -- not "chips or fries," i.e., you get to have one or the other when you order this burger. Very nice place overall, very pleasant staff, very clean. Oh, they don't take credit or debit cards, which is kind of weird these days, when the rest of the world seems to be going in the opposite direction. They do have an ATM in the back so you can get cash. read more

Service was excellent, all the servers were so very kind. Food was very good. Overall, a very good experience and I would go back for sure.

Wandered in here yesterday during our first trip to Boulder- in fact our first trip to Colorado! The staff was beyond professional and friendly! It seemed like our server was being trained and coming from a food service background I could tell they value the importance of training staff properly! The servers seem to all work well together and don't make you feel like 'you're not my table'. Had a lovely conversation with Christian, bonded over some common interests! I wasn't going to have a beer initially but seeing the beers go by me changed my mind! They offered me a sample of the Soul Flower Saison which was so delicious I ordered it! Husband had a chicken sandwich and I had the chicken quesadilla. We were happy with the taste and the quality of the food but we'll especially remember our experience here fondly for the friendly atmosphere! FYI-CASH ONLY read more
