Chris Frankel, the proprietor of eclectic Midtown bar Spare Key, is a man who does his research. Starting with Hawaii and ending with Alaska, he visited every single US state to compile his establishment’s pièce de résistance: a menu of 51 cocktails, each named after and inspired by its state of origin (plus, of course, one for Washington, D.C.). The goal for customers is to “unlock” the Spare Key menu by trying them all. What do they get for completing the mission? “A special prize,” Frankel hints.
