The far-reaching influence of New York's reigning queen of mixology, Audrey Saunders, is hard to measure. Her storied cocktail lounge, the Pegu Club, begat many of today's standard-bearers, including Death & Company, PDT and Mayahuel. Pay a visit to the urbane barroom, a second floor sanctum on bustling Houston Street, and explore Saunders’ eminent opus, which includes new classics such as the Gin-Gin Mule. She first served the drink—a vivacious elixir of homemade ginger beer with Tanqueray gin, fresh mint and lime juice—at the Beacon Restaurant & Bar in 2000. Equally renowned is the Earl Grey MarTEAni, a frothy and fragrant nod to English teatime traditions made with loose-leaf–infused Tanqueray gin, lemon juice and an egg white.
