With Chinois, I feel like Wolfgang Puck sort of sold out... It's definitely a PF Changs type restaurant, with moderate quality food for a moderate price.
This restaurant is located in the Forum Shops at the Ceasar's Palace, so if you're hungry while you're shopping, it's not a bad place to stop and eat. I really enjoy the tofu dish with the reddish sauce -- I can't remember what it is called, but I recall that it was the only tofu dish on the menu.
Note that drinks are extremely overpriced.
