If you want to come for burgers fries and a shake, this is the spot. I come to Cosmo Burger all the time and have ordered to go multiple times. The burgers are always perfectly cooked and the fries are the optimal texture and cut. The grilled onions are a welcomed addition. The vibe is more of a bar vibe. Service is hit or miss. If it is a weekend evening, there will probably be a wait. There are only 6 booths and 5 2-person tables and a bar that seats 10 people. I love that they offer both a vegan burger (Impossible Burger) and vegan shakes for any variation on the menu! They also have vegan dipping sauce. It is pricey if you want any vegetables besides grilled onions on your burger. Heads up that they only have street parking. read more

was looking for a new smash burger spot in kc and stumbled across this place. parking was tough so plan ahead. we were seated almost immediately at the booths and given menus and waters. i was a bit confused as to why this place needed waitresses and table service as burger spots are usually fast unless it's a gourmet place and they didn't use plates or silverware. the menu was a bit confusing pricing wise but we got two basic burgers and sides. the tots are the best, skip the fries! and the food came out pretty fast. despite the place having table service, our waters weren't refilled once and i noticed as more parties would come in they were moving trash off the tables themselves to sit down. the workers almost seemed overwhelmed by the fast turnover of customers. i think this place would be much better with counter service or something. i feel like chick fil a or even culvers gives better service. Maybe it was just an off day but i probably won't be back read more

I've been a fan of Cosmo Burger for a while now. I was peeved at first about having to make the trek into the city instead of Lenexa City Center, just minutes from my job. But I'd move mountains for these burgers I think. I've already been blown away by their vegan options in the past but getting a dairy free shake alongside my burger today was... the cherry on top. My milkshake came with sprinkles though, no cherry. Do you like burger? Eat here. No regret. read more

Burger delicous as always. Be sure to hit it up during May to try seasonal mango sticky rice milkshake. The mango flavor is overtakken by the rice, but amazing to enjoy. Looking forward to trying kimchi burger in the next couple of days too. read more

This place burger hits way more than their salty tots. I know I wasn't the only one because the table next to us barely touch their tots. It was so salty, I drank one cup of water for over a few bites. As for their burgers, it was way delicious and worth it. Their original and Kim chee burger was delicious. Their shakes are good too! As for their venue, it's spacious, plenty of seats, and it fits in the crossroads area. read more

We went to Cosmo Burger for a quick bite. You walk in and seat yourself. Then someone comes to take your order. The women working were friendly but getting the food took a while considering they only serve one item - smash burgers . The restaurant was nicely decorated and clean. The burger was delicious though. The edges of the patty were crispy. The kids burger is just meat, cheese and bun. It's the same size as a single burger. I didn't ask about a military discount. With a kids burger, single burger, and fries was around $24. read more

This spot is a hidden gem--honestly, the picture says it all. Such a cute, vibey diner that's perfect for catching up with friends or taking yourself on a little solo date (highly recommend). Burger, shake, and tots? Elite combo. I love that you can customize with extra toppings, swap tots or fries, and even choose between a regular or a spiked shake. Every time I've gone, the staff has been super nice and attentive too. Definitely worth a visit if you haven't tried it yet read more

Great food, quick service, and a laid-back atmosphere make this an easy recommendation. Definitely a spot that's earned a place on my KC favorites list read more

Like every place in the Crossroads, parking is nonexistent. This is a cute little diner with a very simple menu. It was clean, bright, and service was fast and friendly. I ordered a single minus onions add tomato and my son had a double as-is. I ordered Diet Coke and he had a vanilla shake and tots. Everything was delicious and as expected. No complaints, I would recommend. read more

Smash burgers were great! Single for me, double for hubby and we were both happy. Recommend the 50/50 for fries and tots. This is a relaxed bar/restaurant and an easy place to spend some time, as evidenced by the regulars we saw! Right across from Grinders, so might be a great place to grab a bite before a concert. read more

For a fun and casual date night, my partner and I went to Cosmo Burger! We loved the retro vibes and the smash burgers that hit the spot!! When we got to Cosmo Burger, we arrived just at the right time where they had some openings. The host told us that a lot of times, you will have to come in and get on the wait list (there isn't an online wait list or reservation system), so it seems like you may have to check in and go grab a drink somewhere else while you wait, as an FYI. Once we were seated, we got beers and ordered our burgers (and fries!). Everything came out quickly and tasted delish! The whole dinner experience didn't last more than 45 minutes to an hour (I drink beers slowly!), so it was definitely a quick bite. The sides of fries or tots are to share and I'm so glad we only got one! Looking forward to going back at some point to try some of their other drinks and have another great burger! read more

One of the best burgers in all of the Kansas City Metro area. Full stop. It's also one of the messiest burgers in the Kansas City Metro area. Also full stop. But messy is good! Cosmo Burger XR has taken their game from a small insert inside Dodson's in the Waldo area, as far out west to the Lenexa City Center, and now in the Crossroads. The location is great, the space is even better, and the food, well, it's pretty outstanding. You are there for a burger - as the name implies - so you should expect a really good one. They don't mess around with styles and toppings, no, they just give you a choice: how many patties do you want? A double burger is a fairly good size burger, and you can adorn it however you want. My recommendation: grilled onions, bacon, and their house pickles. Hit that up with a side of their 'burger sauce' and you have yourself a really good burg. Just know that their house pickles have a little bit of a kick to them, so if you get with that, then they're really good. And even if condiments aren't your thing, their burger sauce compliments the smashed burger patties really well. The service, particularly at the bar, is really good. Always patient, always pleasant, and willing to make a suggestion here & there based on your palate. I would not have thought to try the 'Hamm Sandwich', a cheap can of beer with a shot of Four Roses and a shot of pickle juice, but I'm glad I did because it was suggested to me. Great space, awful parking, REALLY good burgers, and it seems like it fits in the Crossroads and has been there for years. read more

Pretty good just nothing exceptional. Tried the vegan burger with vegan cheese (even though I'm just vegetarian and could have had regular American cheese). Grilled onions were a nice touch but otherwise pretty basic. Fries were standard affair and not fresh cut. Value seemed a little steep too. Was $19 before tax and tip. For food and value would probably give 3 stars but the staff were friendly so giving 4 stars. read more

Cosmos really does a great hamburger! You can tell it was done on a seasoned flat top! You only have 4 choices of hamburgers, fries or tater tots! We took our teenage granddaughter w/ us! She loved it & wants to go back! Definite 2 thumbs up! Winner! read more

First time here and WOW!!! Truly blown away with how good it is! Started with the pickle margarita and it was to die for good! Not too sweet not too pickle perfect amount of salt 10/10 delish. Then I had the single burger and added lettuce, it was so yummy, cooked to perfection and just amazing! The fries were perfectly crispy and salty. The bag of fries was also a very generous helping! Also their ranch and fry sauce are both very good read more

This place is a small hole in the wall. I will say it's a very friendly place but they aren't very attentive which I personally love it because I hate being bothered while eating! They also give you a perfect amount of time to browse the menu before ordering so you don't feel rushed. Now the food, personally wasn't a big fan of their pickles but the burger itself was amazing. They're smash burgers which you can customize to your liking. I got mine with extra grilled onions and it was delicious. I was a fan of the fires more than the tots. If you're opting for dessert I got the chocolate milkshake with the peanut butter whiskey and it was honestly delicious! Definitely worth a try! read more

I've seen so many "advertising" on social media about Cosmo. This fairly new location is fun, bright space with booths, table and bar seating. Service with a smile and good banter is always a good sign. Ordered to go: fries and 2 shakes : N/A Elvis Shake and Strawberry. Even though their fries are not freshly cut and cooked they were good. The dipping sauce/aoili provided was tangy and good. The shakes made with ice cream, milk and fresh ingredients are Devine temptation! Peanut butter & bacon.. how could you go wrong! read more

I'd heard good things and was excited that they opened in the crossroads because it's closer to me than the Waldo location. I headed over for a drink and some food to go. The interior isn't super big but they do have a decent amount of seating for the space. Service was friendly and the food came out fast and was accurate. They have lots of drink options-beers, cocktails, floats, shakes-alcoholic and non, soft drinks really everything. I regret not getting a shake because it looked pretty good. But that will just have to be next time. I tried the prickly pear seltzer: tequila, prickly pear syrup, lime acid, house carbonated. It was so pretty. And it was really nice and refreshing. I'd definitely order it again. The menu is simply burgers and fries or tots and a couple desserts. I went with a double and added an egg and bacon. I also ordered tots. Everything was really good. My only complaint is that someone in the kitchen had a super heavy hand with the salt. I'm not sensitive to salt and I do tend to like salty things but this was a bit much even for me. I'm definitely going to return to try it again because I don't think this is the norm. But overall it was good. Definitely check them out in the crossroads! read more

We came on a Saturday night and though it was busy, we had no problem sitting at the bar right away. We ordered relatively quick but service was a it backed up due to the crowded spot. However, it's worth the wait, the burgers came out fresh and the tots were perfectly golden! A perfect spot on the crossroads! read more

I can check this restaurant off my list. I finally had the chance to see what the hype was about, and let me just say, I wasn't impressed. The space was a lot smaller than I'd envisioned, the food was average, and the service wasn't that great. I ordered a double burger with bacon, along with a side of half tots and half fries. Our food came out within 10 minutes. The burgers were hot and fresh, but the fries and tots didn't seem all that fresh. I also tried a cherry limeade phosphate, which was pretty good. Overall, it's just another burger joint nothing fancy or standout about it. I might return eventually, but it's not a place I see myself craving. read more

Partner and I came in for a burger which is good considering the menu is quite limited, and we devoured them! Classic smash burger grilled to perfection! Fries were basic but I sense this is more of late night spot in the sense that those who are about and about late at night looking for a quick greasy fix need look no further. Old school diner vibe with a few tvs, overall not too loud though. Service was fine, didn't see our server much but food came out quick! read more

Cosmo Burger XR just opened in the Crossroads and it's already a KC favorite for me! The space has a fun retro diner vibe with a modern twist--perfect for a night out or a late-night bite. We kicked things off with drinks: the pickle margarita (way better than it sounds--refreshing and tangy!) and the prickly pear seltzer (light and crisp). The burgers are the star--juicy smash patties with crispy edges, melty cheese, grilled onions, and their signature burger sauce. I added lettuce, tomato, and pickles, while my friend went classic with a double and fries. Both fries and tots were perfectly crispy. Love that they also have vegan options! We finished with the Elvis Shake (peanut butter, banana, chocolate, and bacon). I skipped the bacon but it was still so rich and delicious. Friendly staff, creative drinks, and seriously good burgers--Cosmo Burger XR is a must-try in the Crossroads! read more

I put Cosmo in my top 3 burger joints after visiting the now closed Lenexa location. I'm so glad they are a lot closer to me with the new Crossroads (XR) space. Much more fun than a food hall in the suburbs, with an expanded menu and tables and booths along with a full bar. I ordered a single with standard toppings and added bacon and goobered it with peanut butter and chopped green chilis. Any regrets? Yes, I should have had a double just to prolong the profound enjoyment that my taste buds were experiencing. Not only do they remain in my Top 3 burger joints, they now tie for #1. The bartender told me they have had 2 hour long waits since they opened. It's that damn good. My order of tots were large and the burger sauce for dipping made them equally memorable. Returning soon and often! read more

I went for an early lunch right when they opened to beat any sort of lunch rush. My wife and I figured this would be a good time to go because a few weeks prior they had a 45 minute wait to get a table for dinner on a Saturday. We've always been fans of Cosmo Burger so we were determined to get out to this new location. The space is cool. The food was great too. I had a single burger and tots. They're generous with fries and tots and almost fill the bag all the way. We couldn't resist the temptation of dessert after looking at the milkshake, float and soda menu. Looking back, we made the right choice by ordering shakes. read more

Wow. This spot showed up on a Yelp search for a good smashburger and my word was it just that. A little hard to find, Cosmo burger is a counter tucked into the corner of Dodson's Bar and Commons that is truly taking something simple and making art with it. Like is the case with the best burger-joints, there are only a couple of options for you to choose between. Ultimately, you can select a pre-built burger or build your own with a choice of one, two, or three patties. Then you have a large selection of ingredients you can add from there but I don't recommend watering it down too much because the flavor is tremendous. Cosmo burger is one of those places that unapologetically is kicking ass and not needing too much recognition. The staff is fun and humble and deserving of a massive amount of gratitude for the flat-top art they are performing. Whether you're nursing a hangover on a Sunday morning or just looking for a bite to go along with a fine-crafted cocktail, Cosmo Burger might just be one of the best smashburger you'll ever have. read more

Cosmo Burger is one of those places that absolutely lives up to the hype every time. I'm so glad Cosmo Burger has opened this Crossroads location. The vibes are super cool, and I love all of the retro branding on the menus and signage. I'm used to Cosmo Burger's counter service/online ordering locations, but this is a sit down restaurant. Service was quick and friendly. The food menu is intentionally slim. Just burgers and fries and tots cooked to absolute perfection. They even have a vegan smash burger as well! The drink menu on the other hand is extensive! The milkshake was delicious, but I have heard great things about the pickle margarita. How can I even describe how good the burgers are? Perfectly crispy edges, perfect pickles, perfect carmelized onions. Just perfect. Street parking in Crossroads can be a challenge on weekends, but on a weeknight there is plenty of street parking available in this area. Can't wait to come back often and eat more burgers! read more

Stopped in for a snack and a drink. The Prickly Pear Seltzer was GORGEOUS and tasted so good !! Would come back for that alone. The tots and fries were good, but nothing to write home about.

Cosmo Burger has staked its claim to cooking one of Kansas City's best smash burgers and are upping their game with this location. Not only can order their fantastic burgers (don't forget the tots and special sauce,) but you can wash them down with a delicious milkshake (adult versions are available) or cocktail. It's a heck of a match. The inside has a bit of a retro feel (I kind of wanted to order a Pepsi Free) with an old school bar that wraps around the room and booths constructed along the outside wall. It's a little cozy when it gets busy. Please prepare to wait during peak times. read more

Since I can't have In-N-Out I'll settle for this place. In all seriousness Cosmo Burger is my favorite burger place in the Midwest. The burgers never disappoint. The staff is friendly and efficient.

I have been wanting to try this place so long because I've heard so many good things. I have to say, the burger, the bun, onions... all were cooked so well. Texture-wise, couldn't have been better. The bad part is, it was SO SALTY. It tasted like there was a tablespoon of Worcestershire or Fiesh Sauce dumped on it. An incredibly overpowering umami that made it such a let-down. Now, because of the hype I'm gonna chalk it up as one of the cooks just not paying attention, because I can easily see how this burger gets so much love from people. I'm hoping next time I get it at its best. read more

As a vegetarian, I don't typically choose a place with "burger" in the title, but I had heard great things about Cosmo Burger. I came in on a Monday night. The place was popping! My friend and I were quickly served our waters and beverages. I got the Beyond Burger (which is actually vegan). The burger and sauce were DELICIOUS. I also had a side of crispy and perfectly salted tots. My friend got the Double Cheese and loved it as well. If you're looking for a good burger, this is definitely the place. read more

I thought the flavor of their burger and chocolate shake was good. I "goobered it" with peanut butter and jalapeno jam. That's the most important thing, but I have some feelings here that aren't great... 1). The smashed patty was miniscule. I know being smashed it is supposed to be flat but considering I'm paying $15 for a burger I don't consider it a value. The bun was standard, nothing special. They only have American cheese - which they seemed possibly proud of? American cheese is far from "good" unless you are a kid. Other than that the only other thing I'd mention I won't "ding" them for, as it is a pet peeves of mine...wobbly table! We hates them, Precious! Anyway, service was good and environment was nice and comfy, but I haven't decided if I'll go back. read more

The food was absolutely delicious! the sauce they make in house MUST be on your burger. it's tangy and has a hint of mustard flavor to it. compliments the burger fabulously.

Finally tried the highly renowned Cosmo burger and have to say I was underwhelmed. The interior is kind of a weird vibe - it seems a mix matched vibe to me. Food was okay. The burger was straight grease. I'm looking at other yelp pictures and they don't look as greasy as the ones we got so maybe it was an off night. It was literally all you could taste. The standout was the jalapeño jam / peanut butter addition. It had great flavor but it's possible that it's the only other flavor that came through the grease. The tots were super crispy which I enjoyed but fries were subpar. Overall, I have some other burger joints that stand out in kc so I probably wouldn't come back. read more
