I have a special place in my heart for One Barrel. The fantastic beer speaks for itself, but the prices are great (all taps and all styles of beer are $4.5-5.50 and sampler flights are $2 per 5 oz. glass). The ambiance is relaxed yet vibrant--my ideal place to grab a brew.
#2 Strong Belgian Strong Ale is my favorite beer o' the moment. All of the amazing Belgian-style flavor without a hefty price tag. Care Bear Blood is an awesome imperial coffee stout, and the Behemout Imperial IPA is worth going back for alone.
Their best deal is that if you bike there and bring a helmet on Thursdays, your first beer is $1. ONE DOLLAR, PEOPLE! One Barrel knows the way to my heart fo' sho.
