Stopped by tonight for happy hour. Despite the confusion on the menus posted online, our server recommended their Jalapeno Cilantro Hummus to go with our samples of beers. We settled on their Nitro Stout and a Blooming Blossom, both exceptionally good beers. Second round included...More

It's hard not to love everything in Boulder. The people are awesome, the weather and sunshine is great and it's Colorado! That said, it was a bit jam packed at the bar and all tables were taken up as well. This is more of a...More

Regular brewery set up. Nice decor. Good beer selection. The one we picked were very good. However, the fries were terrible and they didn't have other good vegun options

In amongst lots of expensive spots on Pearl Street, the burgers at Mountain Sun were amazing value. Definitely some of the better burgers around, and you get a free sample of any of their beers. Other menu options looked good, too. Busy and bustling inside,...More

I came here with a few friends and had a great time. They have community service so you will talk to whatever server is available which can be kind of confusing for out of towners but I respect and like it. The beer was pretty...More

This place was tremendous! I was totally impressed at the level of service at the back bar while we waited for our table. And the french fries while we waited were special. Every staff member was busy. Asking for orders, serving, pouring beer samples and...More

What a wonderful surprise. Always busy but never hectic. Grilled cheese and fries are great. Hamburger is superb. Staff is friendly and inviting. All around great spot. Just remember... only cash.

We had lunch here recently and really enjoyed it. I had the black bean burrito which was tasty and filling. Be sure to add the side of green chilli sauce to spice it up. My companion had the steak sandwich, he loved it. As we...More

Try the veggie quesadilla's, excellent. A meal in themselves. The rootbeer is like my dad made. Like old-time sarsaparilla rootbeer. And it's not over-the-top sweet like just about every bottled rootbeer out there.

I think their South Boulder location may be able to manage the size. I do. It know the policy of the pub on large groups though. It is cash only so you will need a wad of bills or a local check.

They only take cash so I am guessing they do not sell gift cards. Try Avery brewery or Fate brewery that may sell gift cards

They do not take reservations and are often busy, but very accommodating while you wait. I'm not sure about gluten free.
