Since I never heard of any restaurants in Toon Studio, Well here is my plan of the Gusteau's restaurant from Ratatouille.
Guests will enter in a 5 star restaurant and get served with many type of foods from another part of the world and inculding food that are seen in the film like Linguini's soup, The special order and the Ratatouille what Remy serves to Ego.
While the diners wait, Remy, Emile and on special occasions, Linguini and Colette will come to your table to sign autographs and take pictures with you while you wait and also a bar for adults to collect drinks.
There will be a plan of it soon when I do something about my MS Paint since it's getting quite screwed up recently.
