I like going out to nightclubs on the weekends.  Do you?
I love them, io love the fact that a nightclub is generally distinguished from regular bars, pubs or taverns by the inclusion of a stage for live music.
I love the live music aspect!  Can they also have DJ's though?
Yes of course Dj's are sometimes the most important part of a nightclub
Where were the first nightclubs located?
I'm not sure but i don know that Some nightclub bouncers do not admit people with ripped jeans or other informal clothing wich i think it's not that ok
Is that just at the fancier nightclubs to make them seem more high class?
The upmarket nature of nightclubs can be seen in the inclusion of VIP areas in some nightclubs, i think they should use the vip are for dress code. and YES
