Blue Door Dungeon

The front door may be blue, but the interior world of this well-equipped and sadism-embracing enterprise has a major red thing going on. This is a predominantly straight domain — thus the flaming reds — but torture and masochism are universal concepts, guaranteeing a gay-plus following here. Rooms are rentable by the hour (£50 in 2022) or for extended stays (nine-hour daytime + 13-hour overnight for £275), and come themed (Medical Room, Red Room of Pain, Chill Out Area, the Play Zone etc). Opened 2008. Located just off Chapel Market in Islington. Tube station: Angel.
