I went there last wed the 10th of july at 4 and no line. it was very impressive but not worth the $98 it cost for the 2 of us. Caesars just doesn't get it. They finally get a competitive buffet with Bellagio or Wynn but charge 15 dollars more.
I've been a couple of times for breakfast and dinner. Even though most items are very good, I don't think it is worth the price. If you like the single serving plates, try Wicked Spoon at Cosmo. Although I will say that if you can go for breakfast during the switchover to lunch the Bacchanal might be worth it. But overall I don't think it is worth it for the full standard price.
Wife joined me at the end of a business trip. Really looked forward to the experience. Frankly, although nice, would not go there again. Can't justify the price and overall enjoy the food at Bellagio more. The line was also staggering the afternoon we went.
