I decided to go for the "world's best buffet" (based on some Las Vegas magazines reviews). As soon as we get there we spend 45mn at the self-pay line everyone was packeted there waiting for a table !
Funny thing is that from the line we could see a lot of free tables all around but the staff was not on a particular rush to escort people to thier tables.
After our first 45mn waiting we finally could have access to the buffet, the food was forgettable... compare to other buffets like the Orleans few blocks from there.
I definetly do not recommend this experience.
