We are in Platja d'Aro for a week during which my son will have his 16th birthday. We want to plan a fun evening of dinner and festivities which are appropriate for a teen-birthday, but having some difficulty finding nightlife venues that are not just for adults. By the way, his birthday happens to be on the French national holiday (July 14), so perhaps there are some French communities here celebrating Bastille Day? Also, he loves medieval castles, knights, and that sort of thing. Any suggestions?
