This is quite possibly my favorite place to get Chinese food in the 'flyover' states.
Though some flavors are Americanized, in its bones, the experience here is similar to my experiences in casual / informal restaurants in Asia. The numbered character wall-style menu? Check. The pictures? Check. The complex and sometimes only very slightly differently-named dishes that are vastly different in execution and flavor? Check.
Don't be intimidated if you're new - there are loads of friendly (and often funny) signs to help you navigate your experience here.
Others have already better described the experience, so I will encourage you to read a few more reviews and then grab a friend, two, three, or six and pick some entrees and dim sum-type items to enjoy family style.
Or go alone and order for 6. I consider it a win, either way.
