I'd give it a zero if I could, one of the worst buffets I've ever gone to in Las Vegas or anywhere for that matter.
You expect lines for a good buffet, but not for the really bad ones. It took 30 minutes to get to the cashier, not so much because there were a lot of people, no. It was due to the comical incompetence of the staff. Four registers and only one working with 7 employees manning the one! Despite there being cashiers and hosts and a manager no one seemed to have ever seen the coupons that all these places have for locals every week, or the comp slips that loyal gamblers get from the casino. Literally every single customer seemed like the end of the world as these people had no idea what to do with the coupons or how to process them.
Meanwhile, a host and a manager are getting into a yelling fight in front of everyone when they could have moved the shouting match 4 feet and out of sight of the rest of us.
Now the food: Skip it, just go eat somewhere else.
I did find the mongolian grill okay but the chef there was rude and testy with the other staff and the customers. The rest of the food was generally tasteless and gassy. We left feeling bloated and ripped off, and spent far too much time in the restroom the rest of the night!
The Italian section had moderately okay thin crust pizza.
