Great customer service and great seasoning on the food. Would recommend for those looking for a quick bite in The Cosmopolitan!

If you are looking for an absolute masterclass in the art of the smash burger, Naughty Patty's at The Cosmopolitan completely delivers. Taking over the casual burger spotlight on the Strip, this spot inside Block 16 Urban Food Hall turns fast-casual comfort food into a high-end culinary experience. read more

I love the Naughty Patty burger w/ bacon! The place is at the Cosmopolitan (2nd floor). You order at a counter and then pick up your food. Tater Tots are perfectly crispy outside and yummy inside. Fr, fr. This is a tasty burger. read more

A solid spot for some quick fuel before a night of going out in Vegas. It can't always be a sit down restaurant, so it's nice that the Cosmo has a large food court area with lots of fast-casual options. The menu at Naughty Patty's keeps things classic - choose between a burger, hot dog or a grilled cheese and add tots on the side. The hot dog was actually delicious and grilled to perfection! The tots were also crispy perfection. Quick and easy and definitely hit the spot. read more

Great customer service all around. The staff was friendly, attentive, and made sure our whole group felt taken care of from start to finish. A few people in our group also checked out Lardo's and Hattie B's, and they couldn't stop talking about how good the food was. Definitely a solid spot if you're going out with friends and everyone wants options. Overall, good vibes, great service, and a place I'd come back to without hesitation. read more

In a pinch burger place before the show. Wanted a bite before our show at the Chelsea. 1 level down is a good size court with lots of options. Naughty Patty's I'm guessing takes the place of Holstein which was bland at best. This place is a workhorse at least during show nights. A bit of a cold industrial feel with metal seats and not much help if you need something after the fact. Gotta say their fries are tremendously good. In and out good for a pre show bite but not a place to go out of your way for. read more

A solid spot for a quick lunch. We had just left the museum of illusions and needed to refuel when we walked by Naughty Patty's in the Cosmo's food hall area. My mom and I split a burger and seasoned tots and it was perfect for the two of us. Typical steep Vegas prices, but we did think the burger was tasty! Though we didn't try them - the milkshakes looked good too. read more

Naughty Patties is located inside the Cosmopolitan, and overall it was a solid spot--just very Vegas when it comes to pricing. The three of us ordered the patty meals, which come with a burger, fries, and a drink. One thing to note: they don't have fountain drinks, only bottled or canned sodas, which feels a little off for a ~$25 meal. Not a huge deal, but definitely noticeable. The burgers themselves were good--I enjoyed the flavor, and they're classic smash burgers. My only complaint is that they smash them so thin that the patty ends up falling apart while you're eating it. It's almost paper-thin, which made it a little messy and less enjoyable structurally. Still tasted good, just wish there was a bit more substance to it. Now the fries... honestly the highlight. They were super crispy and had a really good Cajun-style seasoning--kind of like Five Guys, but better texture. All of us agreed the fries were amazing. Overall, I'd come back for the fries alone. The food was good, just a little overpriced (but that's Vegas for you). read more

Such a vibe, amazing concretes! Such a wonderful addition to the food hall at cosmo. One of the best burgers in town!

Stopped by on a whim and was honestly impressed. The burger was cooked perfectly, juicy, flavorful, and loaded with fresh toppings. The fries were crispy and hot, and everything came out quickly even though the place was pretty. The staff was friendly and welcoming, and the restaurant was clean and well-maintained. You can tell they care about both the food and the customer experience. Definitely one of the better burger spots I've tried in the area. I'll be coming back the next time I'm craving a great burger. Highly recommend! read more

Was craving a burger and fries and this place more than satisfied. I thought they were both perfect. Surprised by some of the negative reviews because everything was great read more

This is a quick walk up location. The menu has a few options of hotdogs or smash hamburger. Fries available as a side order. Our burgers were well seasoned and the burgers have cheese lettuce and fresh tomato and onions. The fries are crispy and seasoned perfectly. All condiments on the side are available. The service is quick and a few tables available to enjoy your food. It's a louder area with a lot of foot traffic and music. read more

I frequent the Cosmo when we go to Vegas and was pleasantly surprised to see this new addition to Block 16 Food Hall, which is a must stop for me during every Vegas trip/Cosmo stay, as I love Hattie B's. Because of time, I sadly did not get to go there, but ended up trying Naughty Patty's and was very happy to get my burger fix and fries! Pro Tip-order from the online ordering display/panel/kiosk right outside the store front to avoid the line. While I was a little annoyed it took 10 minutes to get my food, it around noon (I am not sure if this is the norm, BUT they were cooking NON STOP). Now, as far as the food, I was surprised the bun was cold (I would have liked warm buns), but the meat was fresh and tasty (they cook it in front of you), so overall was very happy. The fries are also out of this world; they have some sort of spice blend that is almost like crack! If I could get more, I would! I am definitely intrigued by this place and would try it again! read more

I liked the hot dogs here. It felt like an old fashion hot dog. Nice texture and flavor. The burger, not so much. I wasnt really into their smash burgers. It didn't taste juicy and the sauce wasn't my type of flavor. The service is excellent and they were fast! They have a big sitting area with a food court feel. Overall I really liked this place for the hot dogs and fries. The burgers just wasnt my style. Other than that, I definitely go again and I did. Lol! read more

Wow. What a cool restaurant. Loved the vibes and the burgers. Gotta say the concretes were on point. Great spot in the Cosmo.

I've had my share of smashburgers and Naughty Patty's was not good. It lacked flavor. It needed salt and pepper at the very least. The edges weren't crispy as like other spots I've tried. I was disappointed with the fries. I made mines dirty with chili and cheese and it was a slice of American Cheese on top. Not a spot I'd recommend. I think it can be better if they truly made the burgers tasting good. read more

Food was excellent! Quick and friendly service. It has a fun vibe! Will definitely visit again.

I have walked by this place many times and finally stopped in. The counter is simple. Order, wait, pick up. Staff is friendly and explained exactly what items in the menu were. I decided on the hot dog. The meat was cased in a good case and had a good snap. The meat was a little off. Not sure if it was over cooked or just sat precooked. I asked and the staff said they would replace. I said it's ok. I think maybe this is a one off but it's for sure worthy of another try. read more

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. read more

The newest addition to Block 16; we only tried this because Lardo has dropped their Pho'rench Dip sandwich (they said it may come back for Winter and if it does.. go get it now!). Wanting a small snack before our late dinner reservation, we decided to try this. As you would expect here, it's not cheap. The burger alone is $16, you can make it a combo with fries and a drink for $26 total, but if you want to upgrade the drink to beer or concrete (shake), add a few bucks more. So we got the NP Burger as it comes with dressed fries. Wait wasn't too terrible for a fresh smash burger. This didn't hit the spot. Burger was nothing special... it was fine, but this could've been shake shack or in n out at fractions of the price here. I read that some people didn't have hot fries; ours were hot, but even dressed they were tasteless. I had to add salt to them and I NEVER add salt to fries. I will say that the additional seating they added for NPs was nice so there's that, but my recommendation is that if you're eating at Block 16, you can do better, both in taste and value for the price, at Lardo, Tekka, Hattie B's or Bang Bar. read more

Fun concept for a tasty burger, hot dog, grilled cheese, fries, and ice cream. Loved the chili cheese fries, chili is tasty and not spicy. I bet it would be jam packed at nighttime after 10pm.

Strong addition to Block 16 Food Court inside Cosmopolitan. Didn't even know this was here! Located across from Lardo as you're heading towards the Chealsea tower, this spot is at the corner complete with bright lights and added seating! The line to order and pick up food went super fast! Seasoned fries were crispy and fluffy inside while the seasoning wasn't overwhelming. The Burger, at first bite was amazing! Juicy, seasoned well with fresh toppings. $19 for the Combo meal is not bad... plus the cost of bacon! Enjoy!! read more

The food was delicious and prepared the way we wanted it! We dined in. All the empty tables had not been wiped off. People just sat at dirty tables. We tried using the ketchup bottle at our table, it was empty. We tried the bottles at two other tables before we found one that had some ketchup in it. This inattentiveness to the dining experience should be addressed. The food was great, though. Thank you for that' read more

The burger has wonderful flavor and very friendly staff! Convenient location in the food court. Will definitely be back to try shakes!

Las Vegas, you've got glitz, glam, and a million places to drop a dollar... but finding a great burger on the Strip? That's apparently still a side quest. So there I was, strolling through the The Cosmopolitan of Las Vegas, burger dreams alive and well, when I spot Naughty Patty's. The name? Catchy. The vibe? Kinda fun, a little edgy. I'm intrigued. I walk up, scan the menu, and just as I'm trying to decode the "naughty" concept, an employee swoops in ready to take my order. Respect the hustle--but also, give a guy a second. I go all in: Naughty Patty with avocado, bacon, smash sauce on the side, fries, and a Coke (light ice, because we're classy like that). While waiting, I peek around... and whew. The energy behind the counter? Not exactly "we love it here." More like "we're counting down the minutes." Not the most comforting pre-burger vibe. Finally, my name gets called. I grab my order, sit down, unwrap this highly anticipated burger... and boom--no avocado. Not a trace. Not even a whisper of green. So I walk back up, politely explain I ordered avocado. The employee checks and says it wasn't added. Then--plot twist--the same employee who took my order jumps in and goes, "Oh, did you want avocado? You can pay for it." Excuse me??? I did ask for it. Loud, clear, and with bacon as its best friend. I was fully ready to pay the avocado tax--but don't act like this is a surprise guest appearance. At that point, I waved the white flag. No avocado. No argument. Just vibes... slightly annoyed vibes. Back to the burger. And honestly? It didn't redeem itself. Somehow soggy and dry at the same time--a culinary magic trick I didn't ask for. Flavor was mid, texture was confusing, and the whole experience just... didn't hit. Between the awkward service moment, missing ingredients, and a burger that didn't live up to its "naughty" name (more like mildly mischievous at best), I left feeling pretty underwhelmed. Cool concept, but the execution? Needs a serious glow-up. Would I come back? Let's just say... Vegas has plenty of other bets I'd rather place. read more
