A nightclub, music club or club, is an entertainment venue and bar that sometimes operates late into the night. A nightclub is usually distinguished from regular bars, pubs or taverns by the inclusion of a stage for live music, one or more floor areas and a DJ booth, where a DJ plays recorded music. The upmarket nature of nightclubs are often seen within the inclusion of VIP areas in some nightclubs, for celebrities and their guests. Nightclubs are far more likely than pubs or sports bars to use bouncers to screen prospective clubgoers for entry. Some nightclub bouncers don’t admit people with informal clothing or gang apparel as a part of a code . The busiest nights for a nightclub are Friday and Saturday night. Most clubs or club nights cater to certain music genres, like house music or hip hop. Many clubs have recurring club nights on different days of the week. Most club nights specialise in a specific genre or sound for branding effects.
