Depends on your definition of close. Walking distance, there isn't much. Catch, Hooters, Shmidt (sp), El Torito, a bunch of fast foods off the top of my head.
If you don't mind driving a few miles, looks like there are a few restaurants near the Tilted Kilt area on Katella that others on the board might be able to comment better on.
If you go the other way on katella, you are approaching the Disney area.
