Inside, past three sets of doors and a changing room cordoned off with an old tarpaulin, is a shadowy warren of alcoves, cages and dark corners. Knee-high leather boots hang from iron chains looped through ceiling hooks like fetish bunting. A gregarious barman greets regulars while hairy-chested musclemen appear on a small screen next to an ice bucket. A string of closures has caused concern for those interested in a variety of fetishes, but the leather scene seems to have been hardest hit, particularly in London. Bars such as the Coleherne, the Anvil, Bloc, Substation and, most recently, the Hoist, have all disappeared into the annals of gay history, replaced with gastropubs, luxe apartments and identikit offices.
