The Mitchell Brothers O'Farrell Theatre was a strip club at 895 O'Farrell Street near San Francisco's Tenderloin neighborhood. Having opened as an X-rated movie theater by Jim and Artie Mitchell on July 4, 1969, the O'Farrell was one of America's most notorious adult-entertainment establishments. By 1980, the nightspot had popularized close-contact lap dancing, which would become the norm in strip clubs nationwide. Journalist Hunter S. Thompson, a longtime friend of the Mitchells and frequent visitor at the club, went there frequently during the summer of 1985 as part of his research for a possible book on pornography. Thompson called the O'Farrell "the Carnegie Hall of public sex in America" and Playboy magazine praised it as "the place to go in San Francisco!"
