Ping's on Mott Street was wonderful last week (22 Mott Street). I know there've been concerns about inconsistency, but I think this branch is pretty consistent. We had the live peel-it-yourself shrimp -- steamed and incredibly fresh (they are the shrimp jumping around in the tank out front; most of the shrimp dishes you get in chinatown are not these live shrimp), with a great dipping sauce. Make sure to eat all of it -- you can eat most of the head after twisting off the shell. Their version of prawns with black pepper sauce is better than any I've had in NYC (better, e.g., than Oriental Garden Seafood; more complex in its flavors). Their XO sauce is justly celebrated, with big chunks of tiny dried fish, scallops, and God knows what else, and you can ask for it as a dipping sauce for anything else you order. Live scallops with XO sauce were disappointing, though (and not worth the 10 bucks a pop price). Pan-fried noodles with seafood was also excellent. All in all a fabulous feast and even with all the live seafood it didn't come out to more than 30 bucks a person.
