A Harlem Mugger is an alcoholic cocktail usually made with 1/2 oz vodka, 1/2 oz gin, 1/2 oz white rum, 1/2 oz tequila, 3 oz Champagne and topped with cranberry juice. It is normally served straight up and garnished with a wedge of lime.
Created at TGI Fridays Coventry, by bartenders Andy "Snoopy" Paganini and Colin "Smurf" Chamberlain. Called a Harlem Mugger because "it takes your money and kicks your head in!"
