Ate here for the first time yesterday! We came around 11:50am for lunch and the wait was 20 minutes (only one cashier working). We came here on Christmas but our Travelzoo voucher didn't work (on weekends too).
The food was decent. The sushi wasn't good, but I liked the variety of other things, like the Southern food. I enjoyed the shrimp cocktail and white wine clams. The best part though? DESSERT. The ice creams were so pretty, and unlimited cotton candy?! You've got to be kidding me. The guy working there (we came back to look for his name tag but he didn't have one :() was really nice too.
Also, we had an AWESOME server, Rudy (extra star for him). He checked up on us pretty often and was super friendly. He brought us a lot of drinks and we didn't manage to finish it all. There was even hot tea with honey. ^_^
Overall, not the best buffet in Vegas but decent, especially if you love desserts lol. Might come back again???
