“Preppy” is the watchword at this hot spot near Union Station where the byword is “seafood specialties and strong drinks.” The tiled floor, wicker chairs, and fishing theme give the bar a New England vibe. Senate staffers and lobbyists pack the place during happy hour (weekdays 4:30 to 7:30) for discounts on drinks, raw oysters, barbecue shrimp, gumbo, and Maryland crabcakes. Wash it all down with a hefty martini.
