When you visit the French side of the island, stop at Paradise View, a restaurant with a killer view overlooking Orient Bay and St. Barth's to the east. The restaurant is nice, but the real jewel is a little stand called Rums and Spices right outside the restaurant. Bernadine Ali sells bottles of local rums (excellent!), spices and island sauces. She also rescues homeless dogs and cats. Buy a shot of rum for a buck. She uses the buck to feed and care for her homeless friends while she works tirelessly to get them adopted. Then buy something from her. Contribute whatever you can to her cause. The woman is a St. Martin version of Mother Theresa for animals.
Visit Bernadine and help her help the helpless. It will be a highlight of your visit to St. Martin gauranteed!
