The Simpsons have an Izzy’s — a restaurant and deli in the fictional town of Springfield’s Lower East Side. They have several sandwiches named after celebrities, including one named after Krusty the Clown.
This is based on the real Izzy’s Deli in Cincinnati, Ohio, famous for the complimentary pickles Bart references. You can see Izzy Kadetz (the real owner) behind the counter, and his wife Rose is the waitress. They were famous for arguing with each other and being snarky with customers as mentioned by Rose when she responds to Bart sarcastically, “Watch how fast I go” as she mosies away from their table. Their menu is emblazoned with the actual old-style logo from the restaurant.
