I have ranked the three buffets I visited in Las Vegas - Bellagio, Paris & Wynn - in order of my preference below with a short review of each:
3. Paris - The Paris buffet has dropped a lot in my opinion from when I first visited. The atmosphere is still one of the most unique in Vegas. The buffet dropped the raclette station and replaced it with a "fondue" station with several fondues - the garlic one was OK, but nothing special. The crab legs were the sweetest of all the buffets I tried, and the crepes were very good as usual. The French items were done pretty well, but everything else was overcooked and/or just boring. The prime rib was also the least rare of the three.
2. Bellagio - I hadn't been to the Bellagio buffet in a while, but things are still pretty nice there - except for the LONG line. I was not impressed with the atmosphere, which was the least attractive of the three, but the food made up for this. The buffet included lots of fresh seafood including Alaskan king crab and smoked ono, both of which were very good. The main foods were all above average, except for the buffalo top sirloin which was too dry. They had some unique sides including a very good potato/truffle/pastry item. The desserts were excellent, especially the creme brulee and chocolate raspberry torte.
1. Wynn - Wow! Run, don't walk, to the Wynn buffet. It is the most expensive buffet I've been too, but it was well worth it. The atmosphere was very nice, like a fine restaurant, and the food was outstanding. They had the usual starters, but the sushi and smoked sturgeon were very good. They have a noodle & risotto station making fresh entrees - avoid the noodles but don't miss the risotto (you can get anything thrown in). The prime rib and rack of lamb were excellent, and most other meats were above par - including the messy, but good ribs. The desserts were impressive including tiramisu & creme brulee, except the bread pudding and chocolate mousse.
Bottom line, King Wynn reigns supreme with Bellagio coming in second (unless the line is too long) and the Paris heading up the rear. Anyone going to Vegas should visit the Wynn buffet, especially if you're heading to the hilarious Avenue Q show there!
