My two cents is, that for the sake of viability, one shouldn't be too damn fussy about what kind of cyberpunks you attract. The ravers, the cosplayers, the fetishists, the hackers, the geeks, the punks, they've all got something to offer, cover charges if nothing else.
Just play the right music, set up the right kind of decor, serve the right kind of drinks, and see who comes and what grows.
But you do want to keep bikers out, so hire some real salty dogs for security or bikers will set up shop and run drugs and prostitutes through ypur club until they get you shut down. They don't care, they'll just move on to another club.
I suggest keeping a seperate conversation nook away from the dance floor if you can swing a different floor or level, maybe a net cafe or kiosks and an old fashioned video arcade.
Lots of industrial decor, chrome and Tron lines, at any rate.
