This is really expensive, authentic high-quality Chinese food and flawless service. Prices are 2-4x what you would pay in a Chinatown somewhere in the world for the same dish. However, if you keep in mind you are in a high end casino, the prices are reasonable when looked at from that perspective. This is one of the few higher end sit down restaurants that are open for lunch.
Their $15 lunch prix fixe is a good deal. You get a soup, entree, and dessert. The mango papaya cold soup I had for dessert was awesome! Too bad I have no idea where else I can get it.
If you like PF Chang's, you will find Zine to be a couple of classes up and more authentic.
If you like authentic Chinese restaurants usually, you will be complaining at how expensive Zine is but you will appreciate the quality, cleanliness, and service.
I will be back here
