One of my favorite buffet places in Vegas. Bellagio's was meh, Wynn's was good & so was Rio's seafood buffet & Mandalay's. The Buffet at Aria was fun, exciting, enjoyable & honestly quite impressive.
I'm subtracting 1 star because there was a large group of us eating there (about 12 adults, plus I think 3 kids), & they said they'd have to charge an extra $100 bucks to seat us together. My cousin voluntarily paid - through the nose. Never in my life had I heard of an extra $100 charge to seat a big group together. Maybe that's Aria's version of 'Welcome to Vegas'. I'm not sure the place was full, but yeah.
Apart from the annoying $100 charge & the "the buffet" logo with its awful kerning (sorry), there really was nothing to complain about. Vegas really does have amazing chefs, & a bunch of them are at Aria. The place has a young, modern feel to it; the food selection was diverse (there was pizza amongst all the sushi & lobster -- or was that crawfish? no idea, hehe); the seafood was fresh & clean but flavorful; the desserts were adventurous & artistic. It was expensive (can't remember how much, exactly), but it's worth the $ if you're a foodie, or eating there for the experience.
