Helsinki has “sporakoff” a pub-tram.
It still operates.
Did they have toilets?

Some of the comments on Foursquare(!) https://foursquare.com/v/m10-party-tram/4bf7225f5ec320a1a17f86d3 (Is it the same one?)
I understand it doesn’t exist anymore…
The tram’s website exists only in the Wayback Machine https://web.archive.org/web/20140116093305/http://www.bvg.de/index.php/de/3859/name/BERLINERFAHRBAR+mieten.html
The webpage, and I assume the hire service, disappeared in 2014, according to the Wayback Machine.
