Let me first say that the buffet wasn't horrible but wasn't great.
Me and my family came on a weekend for lunch and the prices stemmed normal for a Vegas buffet. The selection was okay but not those really unique foods like the other unique foods at the Wicked Spoon. Once he ate the food we didn't know if it was good or bad. It was a mix of it. Also let me say that the service is good and the buffet seemed clean.
Conclusion:
I really don't recommend coming to the buffet here at the Aria but there's also many other restaurants at the Aria.
