Seafood restaurant at the intersection of Huancheng Lu and Dianchi Lu with morning and night dim sum seatings.
sounds good—wanna have to taste if its really Cantonese style.
Decent dim sum at better prices than the slightly ostentatious decor would suggest. Six of us gorged ourselves on dim sum and non-canto snacks and had a few bottles of beer for about 40 yuan/person.
Be aware that the evening dim sum session doesn't officially start until 8:20, although we started getting our dishes around 7:45.
