A gay bar is a drinking establishment which caters primarily to a gay or lesbian clientele. It may often be called a gay club or pub, and occasionally queer bar, lesbian bar, dyke bar, or boy bar. They include gay nightclubs, entertainment venues which usually do their primary business after dark. Gay bars range in size from the tiny, five-seat bars of Tokyo to large, multi-story "super clubs" with several distinct areas and often more than one dance floor. A large venue may be referred to as a nightclub, club, or bar, while smaller venues are typically called bars and sometimes pubs.
