I was out there a couple of months ago while attending GABF in Denver. Great pub, good food. I like the Gordon IPA. If in Boulder you must check out Avery Brewing Company. They don't have a pub but they have a nice little tasting room and great beers. I also really like Coopersmith's in Fort Collins and Great Divide in Denver. Not sure how much time you have but if you make it to Denver, also be sure and get to The Bull & Bush and The Falling Rock Tap House.
