I have eaten at many buffets in Las Vegas and Around the World!
It was OK, Little pricey for what you get, the presentation looked pretty, seemed like fine dining "buffet style", but the buffet was actually small in items you can pick from!
The food had some great tastes to it, but not all was great!
There are many better buffets in Las Vegas.
Examples are; Cosmo - Wicked Spoon, Bellagio, M Casino Buffet, Caesars Palace are a few Yum Yum Yum I've been to them all!
I do not recommend Buffet at Aria
