Fisherman's Terrace Seafood Restaurant on the third level is the biggest one, traditional dims sum from a menu, very busy, not the best service I've had in Richmond.
Northern Delicacy on the 2nd floor has xiao long bao (soup dumplings), potstickers, small plates of various kinds, a very extensive menu, very busy, and fairly good service. The seating is not the most comfortable (including backless stools) but we've certainly enjoyed our food there. Fun to watch them make soup dumplings, scallion pancakes, etc. in the glass front prep area.
Another place is Four Seasons Hot Pot Restaurant on the third floor. We have not tried it, but all the restaurants seem to have their menus in front of the entries so you can check out what they serve.
There is also a food court with various dumplings, buns, etc being offered. Plus on the first level is a Mondo Gelato in case you don't fill up on dim sum.
Across the street at the President Shopping Center (attached to the Radisson Hotel) is Richmond Mandarin Restaurant. We often eat dim sum there. Again it is menu, good service, small and quieter than Fisherman's, excellant special soup with very large dumpling.
Enjoy, and let us know where you finally go.
Thanks for the info. Went to the Fisherman's Terrace just before 1100. Promptly seated in the gwei-lo section at the very back facing a wall (walking past lots of tables for 2 in the interim). Food was okay but to be honest not as consistent as our usual haunts and the service was as you noted-- desultory at best. We had to ask to have our teapot refilled in spite of taking the lid off etc. Prices were reasonable but overall would not make the trip out from Vancouver for this. The Northern Delicacy looked more interesting but was closed when we were ready to eat.
