long time no see. glad to see you're doing great.
i'll give you an educated, experienced opinion. of all the clubs i've ever dj'd in and promoted and managed, i think the thing that is MOST overlooked and not taken seriously, and causes tremendous discomfort to patrons is the bathroom situation. Many clubs are jammed into buildings that shouldn't be clubs, or were one type of club in on era, yet another type for the new business.
A tricked out plush girls bathroom designed for girls will fill your club ten times over with puss. You know as well as I do, girls do consider that stuff when they go out.
If you have the luxury of building a club from the ground up focus on the things from the patron's view. Traffic flow and plenty of bathroom stations. If a building code calls for 4 urinals put 12 in there. Like I said if you're building your club from the ground up and not moving into a venue that's built.
Make plenty of space for people to get into the bathroom and back out. There's nothing worse than having a great time and having to go wait in a bathroom line for 25 minutes with a bunch of other dudes. The best clubs I've ever been in were built from the ground up to be super clubs.
Bathrooms. Oh, and a coat check. Must have a coat check for the girls.
And, if you really wanna get big pimpin, put a separate bathroom somewhere for the talent to use. Nothing is worse for the staff than having to wait in bathroom lines.
Hope it helps.
