I love the Cosmo, so why not give the buffet a try.  Arrived at 8:30 am which was perfect because it was dead.  Paid $9 extra for AYCD mimosas and bloody Mary's.  Easily drank our money's worth, but I am a buffets best friend, I get one plate and I'm done.  I enjoy that they have small, separated portions, so that your food isn't running into each other.  Had to try the Mac n cheese, and that was probably the best thing I had.  The biscuits n gravy was also yummy.  I think the Wynn buffet is prettier, you don't feel like you are at a buffet, but the service was really good at WS and our waiter even sent us with a to-go drink.
