Let's face it... most of us are not kids playing these expensive miniature games. Sure the companies say they are marketing to children, but most players I meet are pushing 30, balding, and single. So we need a man's map and nothing says "manly" more than a Nightclub with dancing girls and poles and couch rooms.
Like the Dark Alley map, I wanted this map to appear as though it's night time. I wanted to invoke the image of Kingpin or Black Mask sitting at a table when Batman or Daredevil came crashing into the bar.
It was a bit of an artistic liberty to put the dancing girl on the map, but I felt the map wouldn't look right without her. None of the gaming companies print bystanders on their maps so I felt this was a unique leap. I toyed with the idea of not making the bar hindering terrain, but in the end I knew this map would see a ton of play from my Batman Ally team and I wanted to maximize the amount of hindering terrain.
I also wanted to make the couch rooms and bathroom fairly disgusting and I think I have succeeded. My girlfriend was personally grossed out by the stain on the couch. That's a sign of success in my book.
