In one of those hidden courtyards off of Rue du Temple in the Marais is a nice surprise. Inside is the home of the Cafe de la Gare which is actually a small theatre. When you enter the courtyard you can hear music and sometimes the rythmic stamp of feet doing a flaminco as there are dance classes going on on all sides. I was meeting friends at a cafe there in that courtyard at what turned out to be a mexican restaurant.
Just for fun, here is the webcam of that courtyard. You can sometimes see two dogs. One is the mother. A friend told me this. She comes to this website everyday and she saw one rather fat dog, and then, a little later on, two dogs. She never saw the puppies though.
