I recently stumbled across The Attendant in Fitzrovia, London. Quite simply, it's an old underground Victorian toilet that's been converted into a café - complete with original urinals.
Inside, the items on sale are not dissimilar from other cafés, with coffee, tea, cakes etc available. But the very obvious sight of urinals and a hand dryer make for a novel experience.
I usually have a thing about toilets and, although the urinals hadn't been used for around 50 years, I still found myself not wanting to touch any of them!
