There're 8 famous branches of Chinese cuisine, classified according to where these dishes are originated from.
In Taiwan, Szechuan and Cantonese restaurants are more common, and Fujian cusine is already incorporated into Taiwanese cusine, since a lot of Taiwanese people are immigrated here from Fujian county in China 300 - 400 years ago.
The flavors of some dishes were adjusted based on local people's tastes, and some of the dishes were "created" by Taiwanese people. For example, in many Szechuan restaurants, you may order a dish called "Fifth watch spicy fire pot", the ingredients including duck bloods and pig intestines, which is kind of close to the dish "mao xue wang" in Szechuan province in China. But "Fifth watch spicy fire pot" is not available in China. Therefore, if you want to do some really authentic Chinese food, plan a trip to China instead.
