I've now been to three Vegas buffets for dinner and my ranking is:
1. Wicked Spoon at the Cosmopolitan
2. Bellagio Buffet
3. Buffet at Aria
I expected a little bit better. Everything reminded me of what I'd get at an all-inclusive resort. Everything was just a little bit off.
However, I really did appreciate the warm crab legs and had a boatload of them.
There's a sign at the beginning of the line that says the wait is ~1.5 hours from that point. Luckily, the line only took 45 minutes.
