Spotted the place where Piña Caladas were originally created!
Two bartenders from Puerto Rico won a contest for the ownership of their national drink. Ramón "Monchito" Marrero Pérez claims to have first made it at the Caribe Hilton Hotel's Beachcomber Bar in San Juan in 1954, using Don Q Gold rum and the then newly-available coco lópez cream of coconut. Coco lópez was developed in Puerto Rico in 1948 by Don Ramón López-Irizarry, hence the Puerto Rican connection and the 1952 account of the drink's creation. Some say the drink did not acquire its name until the 1960s.
