As others have said, this is a spin off of the PF Chang chain, but it's like fast food style. You order up front and they bring the food to you, so they cut cost on wait staff etc. And it's fairly fast.
One thing I'd definitely recommend is the hot and sour soup. If you are with a group of a few people, get 1 bowl. It isn't a typical bowl, there is enough soup for 5 people. And it's tasty.
