Observe the stars from the top of the Sorbonne, see a film in a private flat, spend an astonishing night in the company of transsexuals, watch lawyers match wits in an oratory debating contest, go for a swim in the nude, crash celebrity parties, listen to a rock group in a squat, cross Paris in a Zodiac boat, meet Master Jodorowsky in person, discover the Baha'i faith and or theosophy, buckle down at a gathering of fetishists, or sleep in the most astonishing hotel rooms in the French capital. Night-time in Paris has never been so full of surprises, if you know where to go.
