6. The Friars Club
The Friars Club, where Susie goes to find comedy talent manager Harry Drake, is a real private club in New York City, located at 57 East 55th Street. The club is known for its celebrity toasts and roasts, which were aired on Comedy Central between 1998 and 2002.
The building the club is located in was not built for the club originally, but as the mansion of an investment banker. For historical accuracy, the club would have indeed been located in this location, having moved here in 1957.
