I think you can have a rubbish night at a good club, and a good night at a rubbish club. Its all an bit in the lap of the gods. Some of the best nights I've had have been in clubs where i wouldn't want to suck up to the cruddy denizens as a performer, but they just happened to have booked a brilliant guest.

Similarly you can go to a brilliant club and some lunatic will think of an ingenious way of sodding up the whole evening for everybody.
