With its cool tropical coconut and pineapple flavors, the piña colada is one of the most popular drinks on the island. Two equally charming San Juan restaurants claim to have conceived this concoction. The elegant and historic Caribe Hilton credits bartender Ramon Marrero with the creation of this sensual drink in 1954; you can sample today's sweet and frothy incarnation at the hotel's swim-up bar. The colonial Barrachina declares its bartender Mingot invented the drink while experimenting in 1963. They have a creamier, more alcoholic version that you can drink in the interior courtyard.
