K.O. Burger

K.O. Burger is a window-service hamburger spot in New York's Chinatown that serves smash burgers. The Knockout Burger and the "I'd Hit That" burger can be ordered with double patties, crispy fries, and jalapeño ranch sauce. Customers press a bell by the window, receive a ticket, and wait about 10 to 12 minutes after ordering. There is no seating inside, so it functions as takeout.
