i don't think you've got time to go clubbing if you're only goin for the wknd (unless there is some special event on or a particular night you wanna go to).
last time we went we looked to see what was on and spoke to some parisian friends....................wasn't one night in the whole city we fancied and moreover, didn't want to waste the next day recovering in bed whilst Paris 'lived, breathed and happened' on our doorstep.
we found some nice bars though that got lively on friday and sat and fulfilled the desire for some nice music and a boogie..........one in particular was like a bigger version of Pacha's Funky Room.
there's a nice one near where you're staying as well
