Another one of my favorite Parisian passages is the Passage du Grand Cerf in the 2nd arrondisement, mostly because of the stark contrast between its beautiful interior and the reality of the sex shops just bordering the entrance on Rue Saint-Denis.
One of my favorite passages in Paris, the Passage Bourg L'Abbé still retains some of the imagery conjured up by Walter Benjamin's descriptions of the arcades in the 19th century. Places that blurred the line between interior and exterior, not just through the architecture but by the nature of the objects on display.
