A beloved Vieques institution on the Malecon in Esperanza (the small, charming village on the south coast of the island that has been the social center of Vieques’s expat and visitor community for decades), Duffy’s delivers cold drinks, fresh island food, and the warm, community-rooted bar energy of an island that takes its extraordinary natural gifts seriously. Vieques is home to Mosquito Bay, the world’s brightest bioluminescent bay, where the water glows electric blue at night; Duffy’s is where you start and end the evening that includes it.
