I've liked Hank's Oyster Bar in DC for years. http://www.hanksdc.com/menu.html It has a funky vibe, a great selection of oysters from the East and West Coast, and a variety of other seafood favorites. It also introduced me to my favorite wine varietal from Spain, Albarino. We headed to the Old Town Alexandria Hank's to indulge in some raw oysters. Unlike the bustling 17th Street location, it's easier to get a walk-in table right away.
