Dear lord, walk 20 feet next door and go to the Dubliner, a much much better place.
I went to school in DC, some of my favorite places are:
the Dubliner (mentioned above)
Front Page (College kinda place, used to have 10 dollar buckets of cheap beer on thursday nights, New Hampshire Ave just south of Dupont Circle)
Froggy Bottom Pub (corner of 22nd and Pennsylvania ave, big GWU hangout, the lady that runs the place is very military friendly)
The Brickskeller (this one's for the beer lovers, around P and 22nd, cool place to just enjoy beer and chill out)
Adams Morgan has a ton of stuff if you just take a cab or ride the metro there and walk around you're sure to find something, same with Georgetown except I found a lot of the places there very expensive and snobbish.
If you're looking for good food, Jaleo, on E and 7th, kinda by the Navy Memorial, is the best restaraunt in the city, as far as I'm concerned, never been to the bar there, but it's pretty popular later in the evening.
