Beijing, China:
Beijing Dadong Kaoyadian (best Peking Duck in town!)
Han Kejia (must have the fish in foil... yum)
San Ge Guizhouren (Guizhou cuisine... very different, worth a try)
Shanghainese Restaurant across the street from the Westin in the Financial District (worth going to this out of the way location for amazing Shanghainese food... great for groups)
