SF Bay Area hound here, about to visit NYC with friends for 10 days around Thanksgiving. Would appreciate recs for good Chinese restaurants (geared toward Chinese clients) in Chinatown (or elsewhere in Manhattan), particularly Shanghai style cuisine, dim sum, and anything else special (more than your ho-hum Cantonese or Sichuan/Hunan).
One of us speaks Cantonese and I speak and read Mandarin, so secret Chinese menus are welcome! :)
Thanks in advance for your help!
