I am not Chinese, but as a Jew from New York, I am almost Chinese.
I find that Chinese food in the UK is much more authentic than Chinese food in the states. If you go somewhere like Hong Kong, the food is very very similar to the Chinese food in the UK (probably because most of the UK chefs are HK born) I much prefer UK Chinese food to US because it has more flavour and just tastes better to me. Although...NOT ENOUGH BROCCOLI!
The Tai Pan in Manchester has the BEST Chinese food outside of HK imo. Thank goodness I live near by it!!!
