The burgers here are good, but you're going to have to pay a premium price just for the fact that it's inside the Cosmo. Here's why you will pony up: you get what you pay for. \n\nThe buns were soft on the outside and toasted on the inside. When you ask for a medium or medium-rare burger, they don't overcook it. Lastly, the seasoning is on point without having a heavy hand with the salt. \n\nI went with the Fun-ghi burger with roasted portobello, gruyere, and truffle oil. Each bite had the perfect amount of flavor without one ingredient overwhelming the next. I tried a bite of my friend's Rising Sun, which had tempura avocado, crispy yam, nori, spicy mayo and a patty with a teriyaki glaze. It was even more amazing. I liked that the burgers had flavor without sacrificing the texture. The beef patty wasn't soft like Umami.\n\nService was quick. They do automatically tack on 18% gratuity for parties of 6.
