In all honesty? No.
Between Disney and CityWalk, they've locked up most of the best of the theme restaurants. Now that's not to say that there aren't some great Orlando restaurants. There are a lot of them around here. But if you're looking for (as Moe said on "The Simpsons") "crazy c--- on the walls", the best you'll do outside of DTD or CW is TGIFriday's, Applebee's, etc.
