Bad Being Bar-There’s plenty of examples of this sort of place, but the ur-example is Overload on Melvin’s Reach.  Six floors of mercenaries, soldiers of fortune, assassins, spies, counter-spies, pirates, changelings, and the other assorted sort of beings that you wouldn’t bring home to Mother and Father.  Great music, good booze, and it’s a slow night if there isn’t a murder somewhere.  Sort of like Omega’s Afterlife Club, but with fewer blue-skinned sexy beings.

(Actually, it’s very safe.  The criminal organization that runs Overload makes it very clear that they want a safe place to have business.  Usually with sarcasm and grav guns.)
