Dinner at the drive-thru
Ratatouille has it’s own crossover as well. The restaurant that Linguini and Remy make famous is called Gusteau’s, used to be the most famous and well-respected restaurant in France. I’m not sure how the legendary chef Auguste Gusteau would feel about his brand being messed with.
But in Cars 2, during the character’s trip to Paris, you can see a very similar -looking restaurant in a town square. Gastow’s (see what they did there?) features a chef car in place of Gusteau’s likeness. I wonder what French onion soup is made of when you’re serving automobiles?
