Sam Woo has been called the best Chinese in O.C. One indication is that the clientele is about 95 percent Chinese. Another is that the service can be rude. Some people say if the service isn't rude it's not real Chinese. There are several Sam Woo restaurants in So.Cal. I think there's one in San Francisco too.
There are three restaurants there. One is take out only. One is called Sam Woo Seafood Restaurant and looks a little expensive. I've never been in there. The 3rd is between the first 2 and that's were I eat. It's usually cheap too.
