The "nude part" is actually clothing optional, and one can wear or don't wear what they want. according to their comfort level. No one cares, however when we were there a couple of weeks ago, 2 couples showed up, and tried (fully dressed) to set up their own chairs in front of the front row, blocking other people's view - a no-no. Regarding beach bars, you'll find quite a variety, all with plenty of parking. A couple of favs - the shrimp Caesar salad @ the Perch Bar & Grill and thin crust pizza at Orange Fever.
