if its clubbing you want just pop on a train into central london
you got:
fabrics - highly recommended if your a D&B junkie
ministry of sound - i think you will know what they play
pacha - same as above
turnmills - varied
koko - very varied but dance music on a weekend
there the ones i goto and are pretty good also you can goto places like watford which is just up the train track.
the clubs there are destinys or area they got a shed load of bars in the high street though but can be a good night out
hope you have a good stay fella
