Meet the newest rule-breaker at Block 16 Urban Food Hall—Naughty Patty’s, where the classic diner gets a rebellious makeover. This isn’t just another burger joint; it’s a bold, flavor-packed experience. At Naughty Patty’s, the smash burgers are sizzling, stacked, and sinfully delicious, seared to crispy perfection and loaded with crave-worthy toppings. Pair it with golden fries and a rich, creamy concrete, and you’ve got a meal that’s equal parts nostalgic and unapologetically indulgent. So go ahead—break the rules, take a bite, and get a little naughty.
You get what you would expect from this fast food location. Decent smash burger and fries at reasonable price. Crowded with mostly young people and they try to tidy the place but it is difficult with this crowd.

Way over priced and over rated, greasy burger, charged me for fries I didn’t order. $44 for a burger, fries, shake. Ouch… won’t be returning.

Okay, I didn't actually try the food other than the milkshakes but I'm going to rate this place five stars just based on the milkshakes because they were amazing, especially the strawberry one.

We ordered chili fries and a chili dog. The chili was not good very dry and had a strong lime taste. Very expensive

Stopped in to check this place out after hearing a lot of buzz. The food was good—fresh and nicely prepared—but pretty basic overall. Nothing that really stood out as memorable or unique.
It felt like you’re mostly paying for the location and the atmosphere, which are definitely great if you’re looking for that kind of experience. It’s a solid spot to try once, especially if you’re visiting, but I probably wouldn’t make it a regular go-to.
Definitely caters more to the tourist crowd in my opinion. Worth checking out, but not the best value if you're mainly going for the food.
