Regarding the location of your condo, you could post a link to the listing and someone here could probably tell you where it is.

Regarding a restaurant in the general area of Billy Folly Road, some suggestions, in no particular order..

La Patrona Restaurant at Simpson Bay Resort TRADITIONAL Mexican fare, which is NOT!! Tex-Mex, in a lovely setting.

Hideaway Restaurant at LaVista Resort Restaurant with a varied menu, with a lovely view of the ocean. Best check with them, the restaurant might be closed in September.

Skipjacks--sorry, too lazy to find the website--Probably some of the best seafood on the island

So French--On Billy Folly Road--Traditional French, a little pricy

Bajatzu--In Maho, so a bit further, but some of the best steaks on the island.

Enjoy!
