The boardwalk bakery has sandwiches (and pastries). The Spoodles window (unless it's closed now) has pizza and salad. There is a small kiosk with hot dogs, fries, sausage sandwiches, and some other items.
You can also get counter service at the Beach Club (indoors) and of course, there is Beaches and Cream at the Beach Club too.
Hope that helps a bit.
