Naughty Patty’s

Naughty Patty’s at Block 16 Urban Food Hall inside The Cosmopolitan is a retro-style burger counter that leans all the way into the smash burger trend. The menu stays tight: thin, lacy-edged patties made from a chuck-and-brisket blend, grilled cheese, and loaded hot dogs, plus golden fries on the side. For something sweet, they’re pouring thick concretes with throwback toppings like Oreo and strawberry shortcake. It’s a quick, guilty-pleasure stop when you’re roaming the casino and want a classic diner fix with a little Vegas attitude.
