As much as I hate buffets, you're missing out if you don't go to at least one in Vegas. I must say the Wynn has the best quality food out of any buffet i've had. Generally they have stations inspired by global themes, in particular asian, italian, mexican etc. While the pure number of items might be less than Bellagio, the quality was significantly better. For dessert, the homemade ice cream was amazing!
On Saturday and Sundays they have champagne brunch which is great... nothing like unlimited boozin in the morning, mimosas here I come! All in all, the buffet is the quintessential Vegas experience, and no better place right now than the Wynn.
