My wife and I are big dim sum eaters and constantly rotate between our three local possibilities: Hong Kong, Neo-China, and China One.
This Sunday we headed to China One. The food is at least potentially good, probably the best of the three restaurants, but the place is so joyless and rundown, and the staff seems so miserable, and all of the fried dishes are stone cold. We left the restaurant feeling vaguely depressed and decided that we would not return. Our impression is that the restaurant has gone from bad to worse in the three years since we've been eating there.
Neo-China, by contrast, is lively and friendly, but the food never manages to be delicious. I'm not quite sure of the problem: everything seems just a little bland, a little sweet, perhaps slightly Westernized.
I guess that leaves Hong Kong. It is likewise rundown, but at least the food is hot and the place does not feel like a morgue. For my money that most delicious dim sum item in the Triangle is the fried shrimp and taro cake served at Hong Kong -- this at least is something to look forward to.
