In "The Perfect Lecture", Frank dines here and throws up. The day afterward, he performs a "perfect lecture" as he calls it and becomes determined to repeat it. To do so, he feels he must do everything he did in the time just before his coveted lecture, so he dines here and vomits repeatedly to repeat his lecture to the disgust of the staff working here, especially Kim.
