I had high expectations and they met them and exceeded them. My burger was fresh, juicy, loaded with all the extras I added on and the tots were crisp and hot. I can’t say enough good things about the food and my experience with the staff. Those guys were incredibly accommodating and proud of the product they put out.

Do yourself a favor and try Cosmo Burger!! We grab takeout here no less than 1x a month and it’s always as good as time before (and a highlight of our week). Absolute STRONG contender for the best burger in KC. Maybe not even a contender.

got food poisoning from double burger with cheese lettuce and tomato. Was sick and threw up 6 times at night. Will never ever come back and not recommend to anyone. ???

Let me tell you.... I you don't think this isn't the BEST burger in all of KC, I'll fight you!! Fresh, high quality meat, soft steamed bun, and fresh condiments. Outstanding! Don't sleep on those tots too!

Love this place! Excellent burgers, vegan options, and you can get a Hamm sandwich at the bar (Hamm's, shot of whiskey with a pickle back shot). Good price and so delicious! Favorite burger in KC.

This place came highly recommended by some friends. My biggest knock on the place was having to order online. It seriously was a pain!! The service was great, and the place has a great atmosphere! The burger definitely was not one of my favorites. I ordered a double cheeseburger, but the patties are so thin you couldn't tell. The McDonalds Quarter Pounder has more meat than the Double. I'll probably give it another try knowing what to expect. Also there were no fries on the menu. ?

Made my list of top 10 things I have eaten and is quickly becoming my favorite burger ever. Originally went with sauce on the side but the second time I ordered, it should go on the burger. My new go to order is two doubles with chopped chillies, pickles, and then another single burger with bacon. If they have a pickle pint in stock, get it.

Best burgers I’ve had in a very long time.

I have one issue with cosmo burger. How the hell am I supposed to get through all of these tater tots? It would be a crime to throw them out and you know I demolished that burger so how am I going to fit all this food??

Got a double burger home, had nothing on it except 3 pickles. The online order system did not have any options to add lettuce, tomato, cheese or onion. Just options for no sauce, no cheese,etc. So it's automatically thought all the trimmings would be included. We added .25 for extra onions. No onions at all. Buyers beware when ordering online, you will not get what you want.
