Americans have long had a love for Chinese food.

"Chinese food is popular in the United States," said Wang Rui, a co-founder of Cuckoo Kitchen. "There are more than 43,000 establishments, and with an annual sales of over $25 billion, it is the second most popular takeout cuisine in America."

However, despite its popularity, most Chinese food in America is perceived as unhealthy and low quality, said Wang, who used to be an actuary at a big insurance company with a high-paying managerial position. He quit months ago.
