they prob used recycled oil/pig oil to deeep fry the chickens. The oil has probably been used like 100 times frying various different things, so that's why tehre's so much 'robust' taste. personally i'm chinese and i like KFC more than the ones from 'chinese restaurants'. Real chinese people never order wings anyway.
Sorry to say this, but if you go into one fo those restaurants with those huge pictures of food items on the wall, chances aren't u aren't going to be eating chinese food. Wings, and those things are catered towards americans. it's like eating taco bell and thinking taht's mexican food.
