I live in a wealthy city in China called Hangzhou, which is about 200 miles south of Shanghai.
In Hangzhou, Shanghai and other cities, Pizza Huts have opened. I have met no foreigner (including myself) who likes Pizza Hut. Pizza Hut's pizzas are greasy, have no taste whatsoever, and expensive. My colon has suffered mightily from eating there. I do like the salad bar and the onion rings (because this is the only place in China that sells them). For the price that one pays at Pizza Hut, one could have a fantastic Chinese meal with wine.
The Chinese love it, and most every night there is a line of people outside their door waiting to get in. Pizza Hut makes their waitstaff wear seasonal costumes, including Halloween and Christmas, two holidays that the Chinese really don't understand or widely celebrate. Pizza Hut has been imitated by several other companies, who more or less make a knock off version of the same crap the Hut dishes out.
Hangzhou has KFC, McDonalds, and Pizza Hut. Shanghai has all that Hangzhou has, plus Subway sandwiches and Papa John's
pizza. Burger King is being test marketed in Shanghai and I hope it succeeds nationwide. Taco bell is being test marketed also, but the Chinese do not like cheese or tacos
I've had KFC in China, Taiwan, South Korea, Thailand, and Vietnam. The food in Vietnam and Thailand are so wonderful, I could not imagine how the KFC's would survive there, but they do. It's fun to eat American fast food in foreign nations because they tend to add their own local specialties, or with pizza, put non traditional stuff on it like fish, corn (which is good), and peas. My friend from Iceland who has lived in Korea and Japan has told me that the KFCs on the Mainland are not as good.
I ate at a Popeye's chicken in Korea that just was not good at all. I always remember Popeyes being good, but the chicken in there was always dry and too spicy.
