I was just talking to my friends about the same frustration I have. Tse Yang in NYC is pretty good, upscale, very clean. The food is a little 'gwai lo', but I only had lunch there. THeir fried rice though is top notch. Those who have real fried rice know what I mean. Fragrant, fluffy egg flakes, light rice, NOT GREASY.
Shanghai Pavillion on the Upper East Side in NYC is pretty clean too. ANd the price is not that bad. Chinatown has great food, but boy, why can't we have a clean place down there?
