Patent Coffee/Patent Pending

NoMad’s Radio Wave Building, a former residence of physicist-inventor Nikola Tesla, is now home to a bar with a split personality. By day, the subterranean space operates as Patent Coffee, serving up espresso drinks, pour-over coffee and pastries. But by night, the coffee bar becomes a candlelit entryway into Patent Pending, a cocktail den concealed behind a secret door. The drinks, organized into Tesla-inspired “Energy,” “Vibration,” “Frequency” and “Descent” categories, come courtesy of Harrison Ginsberg and Nick Rolin, alums of BlackTail and the Dead Rabbit. Exposed lightbulbs and teal leather booths create a relaxed atmosphere perfect for sipping well-crafted drinks like the AC/DC: a blend of Armagnac, peach, fennel, egg white and seltzer (file that one under Energy).
