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

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