I'm split between 3 or 4 stars but I'm deciding to be nice.
Zoozacrackers is pretty solid deli with reasonable prices (at least for the Wynn). Stopped by recently after CES and was pleasantly surprised by the offerings here. Adjacent to the sports book, Zoo offers a great selection of sandwiches, salads, and soups. The deli is pretty casual, walk in, seat yourself, and order at the counter.
My Chicken Sourdough Melt was delicious. For once I could actually taste the provolone and the sourdough was not dry at all. The fries were fresh and crispy worth the additional $4. I know I was overpaying for the food but it was damn good.
Theres a huge dessert display case if you got a sweet tooth. For $13 you get a slice of the biggest cake I've ever seen. It can easily feed 3-4 people; diabetics be warned.
The Wynn Burger is their most popular dish. An all vegan cheese burger (I think the cheese is soy) along with a serving of fries and a small shake all for $9. This is easily the cheapest meal in the entire resort. Though the burger is pretty small, it tastes great and I can tell why its a favorite.
If you're hungry at the Wynn, Zoozacrackers is a great spot to catch a quick bite and not break the bank.
