After Xi'an, you may never want regular American-Chinese food again. Hollis Johnson TimeOut US just named Xi'an Famous Foods the second-best Chinese restaurant in the US.

The New York City-based chain (pronounced "she-ahn") serves authentic, mouthwatering cuisine from the Shaanxi province in northwest China.

Xi'an has enjoyed a lot of attention since it was a food stall in the basement of a mall in Queens. The likes of Anthony Bourdain and Bobby Flay have given it their thumbs-up.

Since 2005 the chain has grown to nine locations throughout New York City, and is proving to be incredibly popular. Xi'an recently also landed on Zagat's first "11 Hottest Fast-Casual Chains" list, further proof of its rise to fast-casual stardom.

It may just be popular enough to take on a larger market and bring real Chinese fast-casual to the Panda Express fast-food market.
