We had lunch here today and found it impressive (selection) but disappointing (quality). I agree with other posters- the selection is leaps and bound beyond anything I've seen around here. However, quality was overall fair-to-poor. The food looked and tasted like it had been sitting around for a while, and since we arrived soon after they opened, our guess was they were reheating stuff from last night. Fried Dumplings on one table were hard and unpleasantly chewy, although gyoza from another table were fresh and much better. The various buns and dumplings in the steamer baskets were OK, but nowhere near as good as what I'm used to from Chau Chau City or even China Pearl. There was no sushi, just maki, and all of it looked like vegetable maki. I passed, but my friend tried and and felt it was not particularly good.
I tried a wide variety of selections and nothing really impressed with the exception of a coconut tart from the sweets table.
At $11 per person we felt we'd had a decent meal- if I was paying dinner or weekend prices I'd have been a lot unhappier, although I wonder if the quality is better at those meals becaus of higher turnover. That may be, but if people come in and try the lunch buffet and get turned off, you're never going to get them in to try the dinner/weekend options. I'd try it again sometime for dinner, but not anytime soon.
We also went to Super 88. I am a big fan of the South Bay store, and was disappointed in comparison to that store. It's a much smaller space and there's much less selection. I also felt like the prices were a lot higher than the South Bay store, but I haven't been there in a while so I might be off base. It's a great addition to the area, and I'm glad to have it around, but I could see myself heading to South Bay when I really want to have a fun browsing trip.
