Dry Dock in Aurora
Old Chicago in Aurora
CB & Potts in Highlands Ranch
Falcon Brewing Company in Parker
I'm right around the corner from Falcon so I spend a fair amount of time there. I actually havent visited Dry Dock yet but from what I've sampled of their beers at Old Chicago i'm really impressed. I also really enjoy CB & Potts.
Cant wrong with any of those places IMO.
