I've only enjoyed this buffet for breakfast, but it was excellent!
Arriving around 9 AM, we were the only two guests there under the age of 60, which gave us a chuckle. Why we were up and at'em that early in Vegas is another story altogether. Anyway, we did have somewhere in the vicinity of a 20-minute wait to be seated, but it was worth it.
The buffet is broken up into multiple stations, each offering different regional French fair. There are obviously your standard breakfast items available, but the more abstract items really drew our attention.
They have $10 bottles of wine (yeah it was breakfast, what of it?) and a great crepe station.
I highly recommend this buffet for breakfast.
