The legal age is supposed to be 18 however as a one-time bar owner in Sosua, i can assure you that unless you are making a real idiot of yourself, 99% of the bars will serve you in the Sosua area. A diplomat I know tells me that there are ocasional crack-downs in the Santo Domingo area, but they are aimed towards Dominican kids whose mothers might have complained to the local cops,and NOT towards tourists. so, i would suggest you don't worry about a legal drinking age, just have a blast, enjoy the Presidente (muy frio por favor) or the Barcelo rum. avoid the Quisqueja, they should have left it in the donkey. Richard if you want some suggestions as to good pubs in the Sosua area send me an e-mail and I will be pleased to try and offer some ideas.
