Okay, had to chime in on this one! First, Oskar Blues has been producing can filled beer bliss for some time now, and you have to love their unabashed loyalty to the aluminum. I've been to the brewery, know the guys there, and have frequented the restaurant in Longmont. However, I do have to disagree with them having the best beer list.
Though robust and well thought out, it is no where near that of Falling Rock Tap House in Denver. Sporting some 70 beers on tap (crafts, rarities, imports, limited's, ABUNDANT locals), and dozens that are off the wall (including a hushed vintage beer list), it flexes the biggest muscle when it comes to beer menu's locally. It's robust selection, and the doting attention it garners from some of the nations best craft brewers (resulting in them receiving special releases from the likes of Stone, Russian River, Dogfish Head, etc), has earned this bar national attention. Beer magazine even named it one of the "Top 125 Places to Have a Beer Before You Die".
Additionally, almost every beer on the Oskar Blues menu (including their own) can be found gracing the Falling Rock roster alongside 60+ other options.
Although it may sound like it, I'm not on the Falling Rock payroll and am a huge fan of the guys at Oskar Blues. I am simply surprised that the clear winner (IMO) wasn't listed and needed to rant. In reality though, with the growing list of restaurants/breweries expanding their beer menus, I guess it us beer drinkers that are the winners. Sorry for the loooong rant all. Cheers.
