This is probably one of the better buffets in Las Vegas, and it is pretty good food, but no longer a good value.
There is reasonable variety -- particularly strong Italian food, and some decent Asian food, plus Mexican and seafood. Unfortunately, there is never any king crab, and snow crab only on weekends or some dinners. Breakfast is a particularly poor value.
Waiting lines are really long unless you have TR diamond or seven stars, or a pass. (I'm a diamond so it only takes 1-3 minutes to be seated).
Staff are great -- friendly, and good about keeping drinks refilled.
