Of all the celebrity chefs to jump on the better-burger bandwagon in the last decade, only Bobby Flay has made an empire of it. Burger names are inspired by his travels across the U.S., and customers are encouraged to “get crunchified,” a term Flay trademarked that means adding a layer of potato chips. The rest of the menu is limited (fries, onion rings and so on), except for the 13 varieties of milkshakes, with and without booze.
