Aria is legit!
Of all the places I walked through and checked out, this was hands down my favorite. EDIT: Talking about the place in general to R2R.. not recommending this as a buffet to OP.
Cosmopolitan is all the rage right now (and it's definitely pretty), but I feel like the over-the-top decor there will be considered out of date and tacky within a few years whereas Aria is simple and clean. Definitely more my style.
To the OP: I'd check out a buffet or two (one of the awesome ones mentioned), but if you're going to be stuck there for business after the first few days anyway, I'd check out some reputable regular restaurants too. I know everyone has their own interests and yours might not be food, but the food I had in Vegas was the most memorable part of my trip there.
