Similar road pattern...

Steve McQueen's trousers are wet suggesting the photograph was taken after dancing...

“To me it does look like the location is the 13,Rue Saint Benoit one. The exterior shots at the beginning (where they are standing by the cars and motorcycle) looks like the open cobble stoned space by the Eglise St Germain des pres. And the exterior shot where they are sitting at the table and the fellow is going in through a full-length window/door is also very similar.”
