Mainhattan is one of the most well known and easy to find of all the sex saunas in Germany. In the context of the commercial sex industry it is used to describe sex shops loosely based on a nudist club model that helps limit the responsibility of owners. Prostitution is totally legal in Germany and laws have been written to try to turn it into a regular profession but issues still remain that many would simply like to avoid.
At the FKKs working women pay a set fee to enter the club for the day. Men pay another fee to enter. They can then make deals between themselves for sex. The owner makes money from everyone who comes to the club without actually employing any sex workers directly. Only the management, security, and service staff are the payroll. This has worked well for years and become a sort of universal model. Prices may vary from one place to the next but the women in each particular establishment tend to charge the same money for the same services.
Mainhattan is no exception. Unlike some other clubs located out of town Mainhattan is located in Frankfurt proper. While some may take light rail tram 11 to Daimlerstrabe Station and others may even walk I imagine most customers reach the place by taxi.
It is so well known in the city that most cab drivers know exactly where it is located without researching the address. The club almost looks like some sort of workshop from outside. Customers simply walk right in through the glass doors and to the front counter to enter. Taxi drivers often follow right behind to do some sort of business with the place though it in no way increases the prices for customers. Nude and semi nude women can often be seen hanging around the entrance which may surprise new guys even more than the open advertising found around town.
The front desk worker and most everyone else in this and every other FKK can speak at least passable English. If a customer is visiting for the first time the way things work will quickly be explained. Those who already know the routine can simply hand over the entrance fee and get on with it. There is an ATM machine in the front lobby but it charges the kind of ridiculous fees that would make any strip club owner feel right at home so preparation minded men bring their money in from somewhere else before coming.
