The food, view and ambience was memorable. The seafood platter with sea bass, bream, prawns and mussels was the best ! Out of the way restaurant but easy to get to with Uber.

Mar do Inferno is a very popular restaurant with many local visitors. Specialized in seafood. Prices are not cheap, but very acceptable for what you get. Try to make a reservation for the terrace with seaview
