My husband is pretty picky too. We have found the buffets generally please everyone, and everyone can find something they like.
Cape May Cafe
Chef Mickeys
1900 Park Fare
Crystal Palace
Hollywood & Vine
There are usually lots of items on the buffets, and all have "kid buffet choices", which are good for adult picky eaters also.
Most of the quick service restaurants have selections that appeal to picky eaters. (Chicken fingers, hot dogs, etc)
