Beaches and Cream at the Beach Club is really fun but you should have a backup since they don't take ADRs and are really crowded sometimes. Swan and/or Dolphin has a similiar restaurant there.
My husband and son really enjoyed the Pizza window at Spoodles.
I personally don't recommend Big River Grille -- haven't had lots of luck there.
If you're at the Boardwalk later in the evening w/o children, try Jellyrolls- the dueling piano bar -- it's lots of fun.
Also, if you don't mind walking, I believe you can walk to the Fantasia mini-golf from the area (it may be a bit far).
