The Sunset Bar & Grill is a legend, as much for the raucous sunset celebrations as for the fact that you're right below the flight path of 757s zooming in and out of Princess Juliana airport—just a few dozen feet, in fact, from the hair on your pretty head. (The flight schedule is even posted on a blackboard.) That, and the treacherous drinks, beachside setting, dive-bar sensibility, and live reggae music, make this a must-do, if only once. It can get mobbed around happy hour.
