They don't understand their own food, Magister, how can they understand Western food? They do understand that to achieve that special pork dumpling taste, the pork should be left to go dangerously off before using it. There have been scares surrounded the likes of McDonalds in China but by and large it's likely to be safer than San Migs' fresh Chinese fish and vegetables, because McDonald itself keeps an eye out for any malpractices. Of course a lot of the food in so-called Western food restaurants in China is just as unhealthy as Chinese food proper. Egg sausage and chips, if cooked by Chinese people in China[left to their own devices] is Chinese food; it'll get the same loving care as a dish of Shanxi noodles,potato and chicken.
