18 years of age is your best shot. They will not allow any minors in the club. The police have executed many raids and fined many niteclubs. You could probably take them to the "Malecon," but I can't guarantee you won't be ticketed. I took my cousins out drinking to the Malecon, in San Pedro de Macoris. We were not approached by the authorities but, it could have been a blue moon out.
