This is one of the few really good seafood restaurants in town...and the only place to order New England-style fried clams! Outstanding choice of oysters, as well as cherrystones. Earlier writer is correct: Eating (and drinking) at the bar is a pleasure. Great location: on the GW 'campus' (such as it is), a block from Pa. Ave., IMF, World bank, and not far from White House.
Only drawbacks: cost ($$$-$$$$), parking (except for after rush-hour), and average-to-slow service.
