If you think Washington, D.C. is the only place to party, you probably haven’t checked out Herndon’s Breakers Sky Lounge. During their happy hour you can score tasty quesadillas and well drinks for a few dollars (beers sell for as little as $1 per bottle). The lounge is rather spacious, so you won't have to worry about bumping into other people unless it's especially crowded. There is also a karaoke section and free pool, which make for great conversation starters. Go here for drinks and bar food or to shoot some pool.
