Seinfeld, the NBC television comedy show about nothing that ran nine seasons was set in Manhattan. The indoor scenes were filmed in California but the outside footage was shot on location in New York businesses. These Seinfeld landmarks are still being visited by tourists. One of these Seinfeld landmarks is the New York Health & Racquet Club, pictured above. Located at 24 E 13th St., this health club was where George urinated in the showers and shoe salesman Jimmy insisted on speaking in the third person. Seinfeld first aired in May 1990.
