A club is an entertainment venue 
Having recently gone to Ibiza and attending numerous clubs there. I feel that most "normal" clubs aren't that entertaining anymore
Nightclub
A nightclub, music club or club, is an entertainment venue and bar that usually operates late into the night. A nightclub is generally distinguished from regular bars, pubs or taverns by the inclusion of a stage for live music, one or more dance floor areas and a DJ booth, where a DJ plays recorded music. The upmarket nature of nightclubs can be seen in the inclusion of VIP areas in some nightclubs, for celebrities and their guests. Nightclubs are much more likely than pubs or sports bars to use
