As part of the ongoing improvements to make the city look more like Disneyland*, the Rue des Rosiers has been completely torn up for re-cobbling. The west end towards the Rue Vieille du Temple (in the photo) is already done, although I think they still have to put the bars in that keep cars from parking. The whole area in front of l'As du Falafel is still dirt and planks.
According to one of the shopkeepers on the street, they're going to make Rue des Rosiers pedestrian-only on Sundays. It's about time!
* Of course, we all know where Disney got the idea in the first place. They're really just trying to make the city look like it did before tarmac was invented. Minus the cholera and plague outbreaks.
