There are many kinds of night-clubs where different music is played and representatives of different sub-cultures hang-out. The main point of difference is basically the music played.
My idea is establishing a True Diversity night-club that would fit the musical preferences of any visitor, serving music invividually, no matter if it's classics, hard rock, trance, house, jazz, latin, country, african, gothic rock, hip-hop, flamenco, pop-music, art-rock, trip-hop, r&b, acid and dance drive.
Just imagine what a typical evening in this club will look like!
