I submitted a long review previously which was, for some reason, deleted. So - I'll try again, but will keep it short this time.
Don't listen to "nattering nabobs of negativity" here. Buffets in NoVa get "bad rap" that they do not deserve, and Peter Pan in particular.
They are surely not upscale, but what they lack in decor and high-brow service, they make up in amazing variety of seafood. Crabs, fish, shrimp, squid and all sorts of other sea creatures prepared in traditional Hong Kong style, and quite tasty.
