Actually long, loose linen pants are quite comfortable, and have the added benefit of keeping mosquitoes off your ankles. I'm one who believes that the nicer spots are deserving of nicer clothing by diners. If you look at any of the French couples you see dining in the fine restaurants in Grand Case, you will find them dressed to the nines. I just find it respectful to dress up a bit for the nice restaurants.

I've seen diners in shorts, t-shirts, and flip flops turned away from a Grand Case restaurant. That was several years ago, and now that business is down somewhat, that may not be the case.

But yes, it is absolutely up to you. <img src="http://www.traveltalkonline.com/forums/images/graemlins/handshake.gif" alt="" />
