In more fashion-conscious towns, such as Miami, Los Angeles, and New York, there's a big tradition of night clubs which don't actually let people in: instead, you wait outside in a big line until a muscular and well-dressed doorkeeper selects you.
I say take this to its logical extreme, and open a night club which doesn't let ANYONE in.
The night club could be called "Blackjack," and to judge by the line of Beautiful People and Celebrities outside its door each night, it would be the hip place to be. Every time the front door accidentally opens, you see flashes of light and hear the thumping bass of house tracks. But you never actually let anyone in to this, the hippest of all night clubs in your city.
On the last night of your club's existence, of course, you DO accept bribes to let people in, but when they enter they see not a hip crowd of dancers, but a completely empty room filled with nothing other than an old TV, a few empty folding chairs, and a portable table on which people were playing blackjack.
