Excellent buffet!
Great selection of food, and good service. Their dessert department was great too.
The line was long, but I found the payment kiosk so the cut the wait in more than half. So this is is the little trick--just go around the line and there are 2-3 kiosk on the left side. The kiosks are not visible from outside.
Other than Wynn, I think Mandalay Bay had the best buffet.
