For a lovely lunch in Grand Case, my vote also goes to Rainbow.
Calmos is nice, but food and beach space at Rainbow are better.
They have a small private lot to park, but you have to get lucky. Chairs are complimentary if you are eating and drinking there. I was amazed at the quality of the food, beef was from South America....yum!



Delicious filet, with cristofene au gratin. I've since gotten the recipe and made this at home. Nice islandy alternative to potatoes.



Nice view, easy water and access.
