I liked Aria. I don't know why so many people give it unfavorable reviews.
Yea, I think the casino could use a bit more personality, but that's about it. The overall design of the place and all of the great food options are tough to beat.
If you're looking for $1.00 beers and a $10.00 buffet, this isn't the place to be. But you're also not going to step into someone's heroin overdose induced vomit stream on your way to get a scone in the morning...
