A gay lifestyle store on Bismarckstraße in Friedrichstadt, on the same short stretch as K1 and a few minutes from the main station.
It stocks books and magazines, films and toys, and it still runs a DVD rental, which is now rare enough to be worth mentioning. The name is literal: the shelves are half bookshop, half sex shop.
It is the one queer retail address the local LGBTQ+ directory lists for the city, so it doubles as a place to pick up flyers and find out what is on.
