A week ago I was in SF. I stayed two blocks from Chinatown and I had Chinease Dim Sum/Dumplings everyday. It was not at a dim sum resturant but rather these hole in the wall places that sold dumplings, and other items you find at more formal dimsum resturants.
You walk in and you see these steam tables with very large steamer selling all kinds of dumplings. It was extremely cheap (especially when I hit a place by accident right before they closed).
I've also seen these places in NY chinatown. Any such place in the Wash/DC area? I thougth it would be a very long shot but if there was one out there someone on this board would know.
