The London-Style South Side Royale was invented by Julie Reiner, co-owner of the Flatiron Lounge in Manhattan and Clover Club in Brooklyn. This easy-to-prepare cocktail makes for good party-friendly fare. It’s so light and bright that it almost seems…healthy! We like to float a thin slice of cucumber on top to further the illusion of healthfulness.
