Surprisingly, the best Chinese BBQ in Chicago I had was here, not in Chinatown. I've had Peking Duck in Beijing, and this was the closest I've had to it back in Chicago. There was also a great beer selection at good prices to wash it down. For something a little different, go with the eggplant.
The main downside was that service was a bit slow. Especially on a busy night, expect to have to waive your server down. They're not likely to stop by too many times on their own.
Pros: Great food
Cons: Slow service
