Food: Most of their food was presented in individual portions. So it was very convenient to grab whatever looked interesting. I particularly liked that their cocktail shrimp, which came in shot glasses so people aren't digging through a pile. That can get a little unsanitary in a hurry. I loved their carving station. Their beef sirloin was one of the best that I've had in a while at a buffet.
Service: For a Vegas buffet, they have the best service! They were constantly clearing our table of our empty plates and filling our drinks. I have not seen this level of service at all of the other current top buffets including the Bacchanal Buffet at Caesar's Palace. All of their food stations are also kept very clean.
Location: It is located in the Cosmopolitan next to the elevators to the hotel rooms. Very convenient if you're staying at the hotel. From the casino floor, you can take one of the escalators to the second floor and then follow the signs to the buffet.
Bottom line: For me, this buffet is now my go-to buffet whenever I'm in town.
