Your search takes you back to Delirium's node, you were indeed right, there is a commcode provided to call and request access to VIP list.
You copy it to your to-do list.
Otherwise your search is fairly unhelpful. Judging by the number of complaints of rough handling by the bouncers in varying nightclub review forums, they had a "non-nonsense" attitude to trouble makers, but nothing stood out as exceptional regarding their security arrangements.
