Depends on what you want to do. There are also many kinds of restaurants, fast food, ordinary and high-end. See how you position yourself.

However, Chinese food is still very popular in America. Especially fast food, don't look at small business, make money quickly. Ordinary restaurants rely on luck There are good and bad, just like doing it at home.

There is also a market for high-end restaurants or chain high-end restaurants, especially in the rich areas of China.
