The view from the Mix lounge is terrific, and the ride up in the glass elevator is also very fun. The restaurant ambiance is also very nice with a glass bubble chandelier hanging from the center and panoramic views. However, it is still casual. The furniture has started to look a bit worn, or maybe we were seated in a bad corner which was right by the server desk.
There was some complementary bread as a starter, we weren't very hungry so we ordered the entrees directly. They were excellent - Brown Butter Cod and the Mediterranean Rib meat Lamb with Eggplant Lasagna. It was a great combination of flavors. We did not want dessert but the server brought us some complementary fresh baked madeleines with chocolate. It was nice but too sweet for my taste.
Service was ok, our bread and water server was much friendlier than our main server who was just stiffly polite. It seems like the service is variable.
It's a nice restaurant but a little pricey overall and I would probably check out some other restaurants in Mandalay Bay like Fleur and Aureole next.
