My family and I had a terrible dim sum experience at China Chan on a Thursday afternoon. They were out of practically everything we ordered and what we did end up with was sub-par at best. The service was terrible and to tell you the truth, for what we got this place is overpriced.
Here is a list of what we managed to sample: steamed shrimp & beef rice rolls, shrimp dumplings, bean curd rolls, chinese broccoli with oyster sauce, sweet white sponge cake, egg tarts, cocktail buns, and fried sesame balls. All of these items ranged from barely edible to barely acceptable.
Perhaps China Chan does better on the weekends when there is more dim sum traffic and the food is fresher, but I wouldn't choose to come back here. Out of the 3 dim sum restaurants I have tried in PHX, this one ranks dead last for every reason.
