This is the best food in Boulder. Excellent vegetarian choices (the chili is always available) and rotating specials which make it different every time. Lots of taps and plenty of beer choices for various palates.
Often a bit of a wait, but well worth it and you can sample their brews at the bar while you wait.
Atmosphere is a little loud but that is because everyone is having such a good time! The staff are friendly and attentive with great beer advice. Artwork is beautiful.
This is a cash only establishment, so come prepared with real money or pay the ATM fee (a machine is provided in the back).
Also, if you arrive after 10pm, the kitchen is very limited but still worth it.
Brian was our server and he was extremely polite, professional and courteous. My friend and I took forever to order food because we were talking and catching up, and we were never rushed to order! I had blackened chicken quesadillas that had great flavor, crust was cooked perfectly and the lettuce, quack and sour cream on the side was the perfect quantity. My friend had a house salad with chicken and the size and flavor was excellent. We had their FYIPA, that had a nice smooth, full body flavor.
My next trip to Denver will hopefully include a trip back to Mountain Sun Pub and Brewery!!
My boyfriend and I were visiting Boulder from out of town and after 7 days of camping in Nevada and Utah, we were looking for something to fill our stomachs and our souls, haha. We decided to try out this place but had no idea what to expect since we are from out of town. We were truly blown away by everything about this brewery! From the minute we walked in, EVERY single staff member was so incredibly welcoming and kind, clearly going out of the way to make us feel comfortable. The vibes were relaxed and fun inside and the food and beer was amazing! We told them we were thinking about moving to Boulder in the future and they told us if we move here, our first beer would be on the house. So nice! We will definitely be back, as visitors or residents!
4-stars only because the chips suck and the fries are too burnt.
The cold wind howled. And on March 11, 1986, two brothers called ‘The Weasel Boys’ left Corpus Christi, Texas for Boulder, Colorado after witnessing a beached dolphin being ridden to death by a Texas crowd. They started this restaurant and promised to brew beer in honor of their fallen cetacean friend.
It’s the kind of decorations here that make you wonder what kind of Indian designed the walls—call center or casino?
Best steak sandwich (speakeasy steak) with amazing hand cut fries!! Delicious!! Plus the service is friendly and the crowd is nice. Also, how can you beat 21 craft beers on tap?? And cool art, too!!!
This place is awesome and every employee is super friendly. It’s a brewery but they have wine and other drinks and food. We stopped in for drinks and an appetizer and everything was delicious. Beer was amazing especially the chocolate dip. Tastes like candy. Cash only place but…I’m so surprised that they have a self-addressed envelope called a karma envelope where if you don’t have the cash you can take it home and send in your bill later, because they don’t accept credit cards. They are also one of the few retail places where they actually cover health insurance for their employees after 60 days of employment. This place has been here 30 years other than a Covid closure! Please support them! Abbey and Collin were awesome servers and the manager, Hope, was awesome too! She stopped to visit with us and we had a nice chat. We were visiting from Minnesota and will definitely return!!!
My boyfriend and I came in when we were passing through town on vacation. This place was amazing! When the bar wasn’t able to make my drink so the general manager Matt came over to me and told me he could try and substitute the ingredient they were missing. He was so incredibly nice and made one of the best Tom Collin’s I have had in a long time. And the food was so good! I am so happy we stopped in because it made my night. Everyone was super friendly and the dinning area looked really nice. If we go through Colorado again this will be the first place we stop.
This place is special. Very special.
The food was incredible. But that's not even the best of it. I can't think of another restaurant experience I've ever had where the staff seemed so collectively and collaboratively happy, helpful, positive, *relaxed* - all while providing incredible service.
The vibe: it's like you're hanging out at your laid back Deadhead friend's house who also happens to be a world-class host.
I've never before asked a restaurant employee essentially: What's going on at this place?!? (In an absolutely positive and appreciative way.)
We happened to be sitting next to someone who frequents and who also happened to be a global (but Boulder local) travel writer, and he confirmed the experience was consistent and real and special.
Highly recommended. Will be returning.
After years of losing touch with Mountain Sun, I finally got to try it again. COVID really threw a wrench but I’m glad they came back. Their burgers and fries are delicious. Simple as that. Sometimes burgers can be too complex but they simplify their concoctions and excel at it. The camaraderie between employees is amazing. Everything is top notch and I support them every time I go to boulder. Don’t change mountain sun!
I had the worlds best burger— date night burger. It was so good that I never want to have a burger again unless it is the date night burger. It was spectacular, like Ratatouille visual experiences. If I could marry it, I would. Monumental moment in history. Go here for life changing experiences.
