It has that old school look.

I take it the entrances are on the south (bottom) part of the map (slight confusion due to the lack of doors), you have some private rooms as well as semi-private areas in the middle along with a bar. I'm not sure what the rooms to the East and West are for, they seem to have stages. I guess I'm not that hip of a club person, LOL. Maybe they are for private dances? I would also guess the rooms off in the upper right corner are some kind of kitchen area with storage or else some kind of offices? A few more details in there might help to make it obvious to a dope like me what the areas are for.

Congrats on entering a challenge. They are fun to do and you usually get a lot of feedback. If nothing else I keep learning things by doing them.
