Cheapest beer in DC

There are probably bars where you can get a cheaper beer than the $2 Natty Boh's at the Red Derby, but I don't think I'd want to drink there. The Derby, at 3718 14th St. NW, only accepts cash and does most of it's business in cans. They've got a nice selection of beers I haven't tried because I'm broke.

It was packed last night for the debates, the crowd getting a little loud and then shushing itself so that we could all hear. I had a great time, it's relaxed and the red walls and beat up couches are just what I'm looking for in a bar. There's even a pool table in the back, but bring your ATM card, because they only take cash (there's an ATM in the bar).
