Named for the Connaught Bar’s head bartender during the 1940s, this sparkler was the first cocktail on the famed bar’s menu when it reopened in 2008. “Betty is Back is a dry, bubbly sip with delicate floral and citrus notes from a complex blend of Aperol … and elderflower liqueurs and fresh lemon juice,” writes Ago Perrone in his book, The Connaught Bar: Recipes and Iconic Creations, “while the Champagne raises a toast to this memorable wartime bartender and her customers, who kept returning to this iconic spot for more.”
