Just ate there this past Thursday while in Vegas to watch the NCAA tourney.  I've eaten here a couple of times over the years and either they've gone downhill or I remember it being a lot cheaper and a lot better.  I tried a bunch of different things and even though it was buffet I didnt think it was that fresh.  The mahi mahi was rubbery and fishy, the pasta was left out too long and started to dry up, and the desert selection seemed to be quite limited.  The Bellagio or TI buffet is much better.
