I've been here twice. Both times were pretty good. They had tasty crab legs, lamb, and a good variety of everything else. Desserts were great. For the price (I think it was around $30), it's a pretty good value on The Strip. Not as good of a value as Mandalay Bay's buffet, but not bad.
For quality, you still gotta shell out for Wynn or Bellagio though. They're worth it.
