This is an area we didn't discover until the end of our trip. There is a little area in Grand Case that has four different barbecue places right next to each other. The competition keeps their prices really low. Everything is grilled and they have plenty of sides. Two of us ate for about $16. They do have some more expensive choices, but it's a nice price break from the norm on the island.
They have things like lobster, chicken, ribs, shrimp, and more.
