BOIze is Cologne's FLINTA* bar, on Friesenstraße near Friesenplatz. It is one of very few bars left in the city for lesbians and queer women, which is most of why it matters.
There is a bar to sit at and a floor to dance on, with DJs at the weekend. The bar has hosted public viewings and community nights alongside the club nights.
It has been through a renovation and ran pop-up events in the meantime, so it is worth checking its channels before making the trip across town.
