★★☆☆☆ 2.0 Aznin Atl · Jan 2026

The meal, priced at 25, included burgers, fries, and bottled beverages, which is a reasonable value considering its location on the strip. However, the burger itself was quite disappointing. The patty was significantly overcooked, resulting in a very dry texture, and it lacked sufficient seasoning. The seasoned fries, on the other hand, were acceptable.

★★☆☆☆ 2.0 Mitch Stewart · Jan 2026

Love the service and the ambience here. I should’ve ordered the burger though because I ordered the chili dog and fries. Unfortunately, the dog was only lukewarm on the inside. The bun and chili are delicious, but I asked for cheese and then they put it in a wrapper and all the cheese bonded to the paper and was difficult to scrape off. The fries are overly seasoned for me. I really should’ve just gotten the burger!

We came to Naughty Patty's for the Pop Up with Sam the Cooking Guy. We tried the Naughty Sammy burger. One of the best burgers we have ever tried! The Pork carnitas SMASHED in to the Smash burger was so flavorful! The Seasoned fries were perfectly seasoned and crispy. The staff were very friendly. The restaurant is a fun vibe in a convenient location in the Cosmopolitan.

I stopped in hoping to enjoy a good burger, but unfortunately the experience fell short. The staff spent a lot of time loudly complaining about how much they dislike their jobs, which made for an uncomfortable atmosphere and didn’t exactly inspire confidence in the food. When I got back to my hotel and opened the burger, it was disappointing. The patty was dry, and the bun had already become soggy from the cheese by the time I went to eat it. On top of that, the condiment station was messy and poorly maintained — I actually had to open a brand-new bottle of mayonnaise because none of the ones out were usable. Overall, this visit felt disorganized and unwelcoming. I came in wanting a simple, satisfying burger and left pretty disappointed

★★☆☆☆ 2.0 tamica Thomas · Aug 2025

The food was ok. It wasn’t busy so the burgers didn’t taste fresh off the grill. They tasted like they had been sitting a while and the cheese didn’t appear to be new, but looked like they placed a piece over some old cheese. The ambiance is good because it’s on the second level of the Cosmo. We spent $67 on two burgers, two fries and two waters. Was it worth it? No not to me. I won’t come back because there are too many options. The “special sauce” is horrible. Do yourself a favor and ask for it on the side.
