A few miles off of the coast of mainland Puerto Rico is Vieques Island. It’s reasonably small, but still supports a couple of towns, one of which is Esperanza, which caters to tourists a bit more than elsewhere. It was there that we found Duffy’s, a barĀ and grill with food you could probably find anywhere in the rest of the US, but with a distinct island vibe to it.
