Nykris have released a collection of spoken word audio and text files that review many different restrooms in the central London area. The guide will help you decide where to freshen up, by choosing the bathroom with the nicest facilities. The reviews include snippets like this one:

“Plenty of hand washing facilities, lovely clean mirrors, each of the cubicles look very clean indeed and they’ve all got toilet paper.”

Sounds lovely! I would definitely walk an extra few hundred feet to enjoy this bathroom, as opposed to the dirty 7/11 restroom on the corner.

The service may eventually expand into other cities, and there are also other services planned, such as club/bar reviews.
