We ate at Mangoes twice during our trip to Abaco. On the first visit, we ordered the seafood platter to share. The conch fritters were greasy and there wasn't much conch; the dipping sauce was awful. As another reviewer noted, it really needs a spicy sauce. The coconut shrimp were o.k., the chicken wings were way overcooked, so were impossible to eat. I don't remember what else was on the platter; it was pretty unremarkable.
I asked a server where the restrooms were, and she sent me off in the opposite direction, telling me to go left, when they actually were to the right. Very strange. The view of the marina from the outside deck is very pretty.
The second visit we both ordered the hamburger. They actually were the best we ate the entire trip. Cooked perfectly, and the fries were also good. It's actually sad that the best item on the menu was not any seafood item, but a burger. It was really hot on this visit, and they didn't have the fans on, and it was very uncomfortable.
Service was average on both visits; not awful, but nothing special. Note that on their webpage, the menu listed is not the current one. Prices have gone up since that one was posted, and some of the menu selections have changed.
Would I eat here again? Only for the burgers.
