Looking to stuff myself on non-fancy, simply prepared, fresh seafood in a casual sit-down setting where I can also have a few beers at lunch saturday. NoVA or DC location preferred. A place offering multiple oyster varieties would be particularly good (yes, I am aware its May). I generally go to Annapolis or Baltimore area for this kind of thing, but not an option this weekend. Now that I've moved down here, I need to find a place like this if it exists. Any suggestions? Johnny's Half Shell menu looks a bit on the high-brow side for what I'm looking for.
