La Cite de la Mode et la Design
34 quai d'Austerlitz
UPDATE 10/15/14: Vince visited and has this to day: "This is an outdoor photo booth - the only one we could find. It's located outside Wanderlust nightclub, on the dock directly in front of the entrance. The building it's at also houses a very cool design school (Cité de la Mode et du Design) and a hip burger place, so it's worth a visit despite not really being around any other fun tourist activities."
