My friends and I occasionally go to Mister Days on Wednesdays because they have a awesome happy hour were they serve $2 Appetizers and $2 beers between 4:00-9:00pm.
Some Chili...which I am not a fan of, but I don't like beans.
The service is a little below average, but it works most of the time. I don't know how they are the rest of the week, but I can vouch for Wednesdays Happy Hour. This place is about 1-2 blocks away from the Clarendon Metro and there is a parking garage 2 blocks down the road that has $3 parking.
