Venue for Charity Event (Paris)

Hi all, just looking for any suggestions or experienc you may have in this area!

I am helping to organise a Charity event in the autumn in aid of TELETHON, we are currently looking for a venue. The format is probably going to be a nightclub/live music 9pm-3am event with a target of Protected content !

Does anyone know of anywhere suitable (obviously the cheaper the venue itself the more money we raise...so we can't really afford room hire...)

Thanks in advance!
