Zoozacrackers is one of the entry-level restaurants at Wynn. Tucked into the sports book, and being more self-serve, it won't wow most people for ambience. If you're looking for a great deli sandwich, burger or other more casual fare, though, it's the best restaurant in the Wynn.
I had a half corned beef sandwich and a bowl of matzoh ball soup that were better than any NYC deli that I've ever been to. Most of my party ate burgers or sandwiches, and all were impressed with the overall quality of the food.
Full bar in the book or you can get beer from the counter.
Downside is that it is next to the sports book, and across from the casino in open air, so it can be smoky. Other than that, it is a nice staple restaurant for those looking for a $10-15 meal in a hotel where the snacks in the gift shop set you back $8.50 or more.
