It's Official--Dim Sum Go Go and Chinatown Brasserie Best NY Dim Sum
Well maybe not officially official, but I don't think you can find a greater authority on Chinese food these days than Jennifer 8 Lee of the New York Times. And I have to repeat my prior comments--they're unlikely, I had no (actually, negative) expectations before trying them, but I have to agree about these two places. Interesting to see Vegetarian Dim Sum House listed, too. Their snow pea leaf dumplings are definitely fantastic.
