No, Seriously. Guess Where!

A few days ago I posted a funny picture and challenged you to guess where it was taken. So far, no one has guessed, so I'm just going to add another clue or two to stimulate your interest/imagination:

And this next one may make it more obvious . . .

If you were with us when these pictures were taken, you're ineligible to guess. And if you don't live in Paris or have never been, I will accept guesses of general neighborhoods or even arrondissements. Go for it!
