There's a serious lack of counter service options in that area outside the theme parks.
If you are on the dining plan, your only options are the Beach Club Marketplace and the Boardwalk Bakery, or maybe Hurricane Hanna's if the pool is still open. If you're not on the dining plan, you can also use the Spoodles pizza window (till that place closes in its transition to Kouzzina - word is that Kouzzina may keep the pizza window but it might close for the transition, don't know yet) or the kiosks on the Boardwalk itself. You could also try the Fountain or Picabu at the Dolphin (not on the dining plan).
