Le Cottage is located on the main road through Grand Case; however, it's not on the beach. This is probably the only drawback of the restaurant, though.
The food was excellent, and the restaurant even has a wine aficionado who can recommend wines with your entrees. They have a nice array of dishes to choose from and probably the best and most extensive wine list of any restaurant we tried. Not connoisseurs ourselves, we happily took a recommendation and were not disappointed.
I was feeling slightly less adventurous that evening and played it safe with my appetizer by choosing the French Onion soup. It was slightly different than the American standard (maybe a different type of cheese mixed in?), but it was quite tasty. And the lamb dish I tried for my entree was delicious. I topped the meal off with (yet another) chocolate dessert, which was quite good (although not quite as good as the one I tried at Temptation - you can see my recommendation for that as well).
All in all, we really enjoyed our experience at Le Cottage, although we wished the restaurant had been located on the beach. I love the beach terraces at many of the restaurants, and on warm evenings, it makes a big difference!
