someone I know had a party at a nightclub once. I don't know if it was a private party or whether she just booked an area and I can't remember what nightclub it was (it was years ago and I didn't go in the end so can't tell you any more than that I'm afraid)............however, a smallish nightclub might be bookable so you could try surfing the net to find out (someone somewhere must have done a blog about a brilliant birthday party they went to at a club in Singapore at some point....everything else gets blogged about around here!

). So I'd suggest going down that route to see what you can come up with.
