We've heard that Tony Baxter is apparently thinking of ways to put Ratatouille into the parks in some way. Well, they could easily theme Cafe Orleans in New Orleans Square after La Ratatouille from the movie.
It wouldn't take much work to do, just a sign change here and there. But if they really wanted to "plus" it, they could have a large window on the kitchen door where a little animatronic Remy could peek out of the window from time to time. And, although some people don't like this, they could even have character dining with Remy and Emile walking around the tables.
Cafe Orleans is great, but theming it after Ratatouille would make it even better.
