Mofongo is a very Puerto Rican dish that is made from fried plantains. I got my first taste at Puerto Rican food from Mojitos that is toward the bottom of Old San Juan and more by the cruise ships. It is honestly so tastey!
Most people go to Raices, since I believe Man vs Food or another TV show, has gone there. But if you are looking to try Puerto Rican food without such a long ridiculous wait time, try Mojitos!
