Friend of mine had every problem under the sun with a premise in Puerto Banus. Most of the problems came from the town hall inventing petty new rules to do with things like terrace licences and rubbish collection, mainly just to collect fines and invent jobs for town hall bureaucrats. They also had problems with a stubborn landlord who would rather have the place empty the reduce the rent. Be very careful. If possible, get a job in a bar for 6 months to learn the ropes before you put your own capital on the line. I know you will be excited about your plans, but don’t let that cloud your judgement. Good luck.
