This classy seafood joint practically in the shadow of the Capitol building fills up with lobbyists and Hill staffers during happy hour, 4:30 to 7:30 Monday through Friday. The drink deals are nothing special: draft beers $5, cocktails $7 to $9. Discounts on the excellent food are the draw. Oysters are $10 for a half dozen, and you can easily make a meal of a couple of hearty appetizers—a mini-burger ($2.50), grilled squid ($5), barbecue shrimp with Asiago-cheese grits ($6), and more.
