"Fuku’s famed chicken sandwich got its start as an off-menu item at David Chang’s restaurant, Momofuku Noodle Bar. The sandwich earned enough of a following that Chang launched a standalone restaurant in 2015 in New York City called Fuku — a quick-service operation that focused on the sandwich and a couple of side items. It’s grown into a chain with stadium concessions stands since then and is now at T-Mobile Arena in Las Vegas." - Janna Karel
