Eh, I don't know, I didn't find this buffet any special or different from any other buffet in Vegas. Yes, it was good, tons of variety, but I can't say it was memorable (other that the dry sushi which wasn't very tasty). Omelet bar was cool, yummy crab legs, cool little coffee and hot cocoa machines. But the line is incredibly long and it just wasn't so great.
I'd say go once if you really want to, but don't out of your way to make a stop.
