1) I could be wrong, often am, but I don't think most restaurants on SXM serve local seafood, other than lobsters. I believe that most seafood served on island is brought in from France. Bistrot Cariabes does a wonderful Caribbean lobster.

2) Ocean 82. But I do echo someone else's suggestion, go have a big meal for lunch on the ocean somewhere.

3) We haven't made it Orient Village for a couple of years, and our favorites have closed. But not sure why you are ruling out beach bars, as many of the beach bars can rival the food in Grand Case. Most them are not open for dinner though, if that's when you want to go. Unless you're going in dead high season, just drive to the Village and park. Walk around and look at the menus and decide where you want to go based on what looks good.
