Hello
Yes I am confirming about the Old Pirate WIFI. I was in Salou before last week and was many times to use the Old Pirate WIFI. It is free for clients of bar or restaurant.
Also my my wife and children like very much the food and the people. We come to Salou many times and are very happy to know this place
