I want to eat at the Zesty Fork restaurant. I've seen the advert for it a dozen or more times. It's there every time a newspaper or magazine reviews or discusses the film.
The sign is only on screen for a fraction of a second - one of many "blink and you'll miss it" jokes in the film.
The writers probably worked hard coming up with some scenes or clever in-jokes. Unfortunately for them, the bit most people will remember is Homer holding the pig up to the ceiling, singing Spider-pig Spider-pig, does whatever a Spider-pig does....
