Naughty Patty’s to Host Exclusive Pop-Up at The Cosmopolitan This Memorial Day Weekend!

May 4, 2025

LA VEGAS-(KSNV) — Memorial Day Weekend just got tastier in Las Vegas as the celebratory world-famous smash burger act Naughty Patty’s is setting up a one-night pop-up Las Vegas event on Saturday, May 24, at 6 p.m., at The Cosmopolitan of Las Vegas.

This occasion will allow guests to have a special sneak peek at the new venue that will be opening this summer at Block 16 Urban Food Hall. As a bonus, the first 25 people in line will be added to “Patty’s Naughty List,” earning them free Naughty Patty’s for an entire year.

Attendees can expect a mouthwatering menu that includes Naughty Patty’s signature smash burgers, crafted with a bold blend of ground chuck and brisket, seared to perfection, and topped with flavorful fixings. Guests will also enjoy crispy fries seasoned with the brand’s signature “Kitchen Sink” spice blend, and thick Concretes — rich, creamy shakes loaded with toppings like Oreos and strawberries.

Supplies are limited and the event follows a “smash-and-dash” format, meaning once the food runs out, it’s gone, so early arrival is encouraged.

The exact location of the pop-up within The Cosmopolitan will be revealed on the day of the event via @NaughtyPattys on Instagram.

Further details about the full launch of Naughty Patty’s at Block 16 will be shared in the coming months.
