As the show lets out around 10:30 pm, Garnier's façade glows like a jewel and the steps fill with evening gowns. Nobody will ask for a ticket to sit there.
The right time
10:30–11:30 pm: the crowd leaving the show, then the square emptying.
Lights
Façade and golden Apollo lit until 1 am; the Grands Boulevards shop windows stay on.
The photo spot
From the central strip of avenue de l'Opéra, level with rue de la Paix: the whole façade with the lampposts in a row.
The tip
Pigalle and its cabarets are a 10-minute walk up rue des Martyrs — Madame Arthur opens its after-party Thursday to Saturday.
