The Goombay Smash is a Bahamian cocktail made of pineapple juice, orange juice and Malibu rum. It was created by Cyril Watler, who ran the Queen's Bar in Nassau , Bahamas.
However, like with many rum cocktails, there are several variants on the recipe, each claiming to be the original/true goombay smash. After hearing about the Caribbean chain, Bahama Breeze introduced a new island cocktail menu, which included this one.
