Here's a list of some of my favorites -
Lolos in Grand Case. Piazza Pascal, Grand Case. The Palms in Simpson Bay, St Maarten Yacht Club's Happy Hour Grouper Fingers in Simpson Bay, Chesterfields in Philipsburg, Buccaneer Beach Bar in Simpson Bay, El Zarfino Beach Bar, Pineapple Petes Simpson Bay, Big Fish in Oyster Pond, Dinghy Dock Bar in Simpson Bay and Oyster Pond.
A stop at Maho Beach at end of runway, Tijon in Grand Case for perfume/cologne making class.
