I think picky eaters might do better at cape may because there are so many choices. I do recommend, however, not getting the first seating (5:30) We did this last time and it was sooooo crowded. If we had gone closer to 6 or 6:30, it was a lot less crowded.
If you are looking for fun, go to Ohana. kids might find some of the polynesian tastes weird, although I am sure they have some standard "kids" dishes.
My thoughts on garden grill are that the foods there are more traditional, so you won't be suprised by weird tastes. Also, we went here when it was not very crowded (around 6 I think) and we had chip and dale at our table for quite a while. We even chased them around the little circle! It was a lot of fun. It's kind of neat for kids too because it revolves and they can look at all the different scenes, but still stay in their seat.
