I should really know better... Any restaurant in the Wynn is going to be pricey.
We were there for a show and wanted to grab a quick bite before heading in. Zoozacrackers offers a wide variety on their menu from appetizers like Buffalo Wings to burgers to pasta.
Their lines are long but seem to move pretty fast. You order first, find a table and they bring your food out to you. Luckily we didn't have to wait long before our food arrived. Buffalo wings are just ok along with the wrap and fries.
It's not a place to rush back to but it's probably the cheapest in the Wynn.
