This buffet is alright. It has the essentials which are prime rib and crab legs. What it doesn't have is a modern/clean look and beautiful scenery. I guess I started off by saying these things because I went to Bacchanal Buffet the day before at Caesar's Palace and that blew away every single buffet experience I've ever had.
The buffet at the Bellagio is obviously better than a random buffet off the strip. You pay for what you get for here (~$40 for a tasty buffet that's not bad). Paying $12 for all your can eat garbage somewhere else isn't comparable. But when you compare it to the Bacchanal Buffet, you'll understand what I'm trying to say in this review. I'm still going to give this place 4 stars (well deserved), but this is really a comparison review to the best buffet in Las Vegas (as already stated).
So, if you're going to only one buffet in Las Vegas, I do not recommend coming here. If for some reason you end up here though, you're stomach will still be happy and money well-spent.
Be sure to crab some crab legs and walk to the pasta station to get them steamed. Oh, and be sure to walk to another location to get butter. This is unlike the amazing/beautiful/spacious Bacchanal Buffet where you get your crab legs steamed and grab butter in the same location (makes sense right?).
