I've been here a half dozen times or so, mostly because it's pretty inexpensive. If you're looking to fill up after a long day of pressing the slot machine "spin" button, you should probably give it a shot. The champagne brunch is worth the price, and the servers I've had have all been fast and generous with the mimosas.
There's probably not a single item on the buffet that you'll "need" to go back for, but as far as overall value for your dollar, it's hard to beat.
I'll go back. More than once.
