I think out of the buffets I tried in vegas, I would have to say that Carnival World Buffet is pretty good. Yes, there was an hour wait on a Sunday afternoon, but if you have a rewards card you can save $4 a person up to 6 people and it's free for the card. I would have to say their selection was great, they had a little bit of everything and everything was pretty good. I have to say props to the crab legs and prime rib. Also, free mimosas on Sunday Brunch, included in the price.
