I had the chance to eat at Duffy's twice on my most recent trip to Vieques. Located in the heart of Esperanza's entertainment district and right off the south shore of the island, you can't ask for a better place to grab a midday meal or late night drinks.
The waitstaff is very much American, as is the cuisine - definitely targeting the tourists that make up the majority of the Malecon crowd. The artisan beer menu is extensive and the food is reasonable priced and delicious. For lunch I had the Miami Cubano, served on island bread, piled high with pork and sliced ham and topped with melted swiss cheese. The fries were battered and fried to perfection. I accompanied the meal with a bottle of El Presidente (a Dominican brew widely available in PR) - all for $13 bucks.
Our group was so impressed with the food and service that we returned that night for dinner, knocking out a couple more bottles of Presidente and this time ordering a Mahi Mahi Wrap. Not as good as the Cubano in my opinion, but still generously sized and stuffed with lettuce, red onions, tomato, and large chunks of Mahi Mahi. Again, the service was top notch and even gave our group some great information on places to go and things to do on the island. I will absolutely return next time I am in Vieques.
