I've spent the last 20 years of my life shuttling between Hong Kong and Tokyo. I have yet to find a single Chinese restaurant in Japan that has some claim to authenticity that I would consider going to more than once.

Now, the Japanese do their own deal with Chinese food, and some of it is quite tasty, at many price points. But saying that what they do to Chinese food is somehow a substitute for the real deal is just daft. Places like the Hei Fung Terrace are an insult to Chinese food, especially at those price points and under a claim of authenticity that doesn't hold water.
