Episode: “The Bowtie” (Season 5, Episode 2)
Address: Various locations
Larry meets Jeff for lunch at the Hollywood burger landmark, where a run-in with Funkhouser's excited daughter causes Larry to launch into a speech about his fame as a “friend o'lesbians.” He also realizes here that he's accidentally swiped his private investigator's bathroom key. Which is almost as strange as a well-known burger spot being just as famous for its French onion soup. Which this place is.
