very good seafood- restaurants close to the farol da barra.
the island "morro de sao paulo" ist very lovely, one hour from salvador city, boats every day.
take a room in a pousada on the 2nd or 3rd beach, there are less peoplo than on the first. when you're arriving in morro, you will be asked if you want to visit different pousadas- he will show you some in you price class, and you can have a look at them before deciding(service which includes the carriage of you bagages) costs about 10 dollars.
lots of restaurants on the island and also fresh fruit drinks(with alcohol) and the beaches are also very nice.
