During a conversation at Krusty Burger, Officer Lou mentioned that he had visited a McDonald's restaurant in Shelbyville and explained that the chain had more than 2,000 locations throughout the state. He described several differences between McDonald's and Krusty Burger, noting that a Krusty Burger with cheese was equivalent to a Quarter Pounder with Cheese, while Krusty Burger's partially gelatinated non-dairy beverages were called shakes at McDonald's.[2]
The Simpsons once ate at a McDonald's located next to the Tower of Pisa in Italy. Wine was served there. Homer marveled at the fact that it was "a McDonald's where you could get drunk!"[6]
