La Mar Salada - Algeciras

Inside the algecireño harbour enclosure (at the interor of the sea station) is of the establishments that are worth taking a coffee or apertitivo simply to give you a tour of the port of algeciras to see the entrance and departure of ships, catamarans, ferris, large container ships, etc. I take my child and usually go there, of course. How could I not have some coffee and sit a little quiet while I looked at the sea?
