Green Door - Pass the famous entrance of the Green Door lounge, and you will follow the lead of multiple high-volume celebs, such as—to name two—Prince or Pink. You better know the art of dropping names though, as this top club is a social fortress. The secession-meets-Belle-Époque décor leans towards an effect of a haunted manor, with large mirrors plus walls and ceilings covered deliberately in big water leaks. The antique furniture and golden chandeliers will make you feel truly aristocratic, and no wonder that even the celebs feel attracted to that mood.
