Depennds on what kinda music you like loh:
For Retro - Check out MW(1&2) and Zouk on Weds
For House - Centro,China Black and Zouk
For Techno - Music Underground, Devil's Bar and Sparks(Loadsa Kids
and Bengs...)
For Trance - Heard that Liquid Room plays good Trance..

BTW, MS and BQ are quite OK, but the dance floor and place is too
small to really enjoy....
