Xinjiang cuisine in NYC area?
The link Chandavkl provided has lots of info. Also there are some older threads on Northern Chinese regional restaurants.
Try searching for Little Pepper on Roosevelt in Flushing which is Szechuan/northern Chinese, Afanti on 41st in Flushing which is Xinjiang/northern Chinese, and Waterfront International on Prince St in Flushing which is Northern Chinese. All three are great.
