He is referring to the pizza chain Little Caesars and their slogan
Ah. Okay, thanks for the clarification. I would have been surprised if it had been a line from the movie because its concept of Italian food is a little odd. At the beginning of the film, Robinson’s character and his sidekick go into a diner and order “spaghetti and coffee for two.” I don’t know what they get served (we don’t get a close-up), but from its general appearance and from the way Robinson uses his utensils to eat his food it sure doesn’t seem to be spaghetti. Given that the titular character, an Italian named Caesar Enrico Bandello, is played by Robinson, who’s of Romanian Jewish birth, I suppose the dubious Italian cuisine fits right in.
