I agree with the previous post. There are too many good restaurants on the island to limit yourselves to one place, however good it might be.
These were some of our favorites during our trip earlier this month:
Jam-Bel Jerk Pit, Elvi's, Capricorn, Sweet Basil (lunch), Papi's Diner, and Estel's (breakfast).
Casa Picasso, El Divino, Maneely's Ice Cream
