It's not a CS, but Beaches and Cream is a great little restaurant that's pretty quick and easy. Priced like a CS, too.
If you have park hoppers, you can pop into Epcot and have fish and chips or grab something from the Tangerine Cafe.
Your other option is the Spoodles pizza window (until Spoodles closes), or the kiosks set up on the Boardwalk that have hot dogs, chicken fingers, subs/burgers, pizza, fries, etc.
