This is for the restaurant, and not the club:
Five stars for the atmosphere, 5 for the view, 5 for service, but only 2 for the food itself.
Riding up the secret elevator to the top floor of the Mandalay Bay was by far the highlight of this experience. The glass elevator propels you high up to the 44th floor, where you have a panoramic view of the strip.

The Boneless Ribeye with black peppercorn was not visually appealing, but its flavor wasn't too bad. Mix's downfall were their side dishes. The Wild Mushroom Fricasee was limp and unflavorful. The Fork Crushed Potatoes tasted starchy and bland. And for something that they're supposed to be "famous" for, the miX Macaroni and Cheese with Ham is to be avoided at all costs, unless you feel like shelling out $9 for Easy-Mac with chunks of Oscar Meyer ham slices.
Service was impeccable though. We were in a rush after dinner, but our server insisted on complimentary dessert for our entire party. I'd definitely return here, but merely for the view/bar/drinks.
