Sexy show

The other day a friend from Besancon came to stay, we went for a walk around Pigalle and Montmartre. This is without doubt the seediest part of the town, full of filthy clubs and cinemas which show sexy DVDs in "booths". I'm not too sure what you are supposed to do in your "booth", I don't like to think about it, but they seem frequented by lonely middle aged men.
There's even a museum of erotica, which is the same thing with an intellectual gloss to make it socially acceptable for people like us to visit it.
We also went to the Cafe Amelie Poulain, which is just like any other cafe in Paris, but more expensive and with even less interest in keeping the customer happy, if such a think is possible. I took a picture of it, but as it looks like any other cafe, it hardly seemed worth putting it up.
