The Booth Diner is where Lois meets with Bonnie, Donna and Elle Hitler to recap her date with Peter at the His & Her's Restaurant the previous night in "The Munchurian Candidate".
While there, she reveals that although the dinner went well, she was disappointed when Peter wasn't willing to perform oral sex on her afterwards. Bonnie suggests seeing a hypnotist that was able to help Joe with the same problem. Before she can elaborate further, they are advised that a birthday party for a six-year old at the next table doesn't appreciate their conversation.
