I am impressed with the Berlin public toilets, though. Here are some pictures I took of a City Toilette: it's wheelchair accessible, non-gendered, and has instructions for use in four languages. Note that unless you have a EuroKey, it costs 50 cents to use the toilet.
I also discovered that in the Kino in der Kulturbrauerei, the women's toilets have a urinal:
This is something I haven't seen before, and I'd welcome opinions on whether this is useful or not!
None of the toilets at the venue are gender-neutral, but OKFest put a sign up to convert one, and also marked it on the map. They responded quickly when I told them I couldn't find it!
.@RachelKnowler The sign on the door called down! Thanks for telling us, we'll put it up again now! #genderneutral #OKFest14
