Under the shimmering red lights of Boulevard de Clichy, the 9th arrondissement has become a magnet for chic Parisian night crawlers. The area retains a certain sleazy, dingy kind of charm, epitomized by places like Le Sans Souci.

The wan exterior of this archetypal brasserie doesn’t look like much by day, but at night this place doesn’t sleep, bursting at the seams with bobos, professionals, internationals, and the token artist. Le Sans Souci means ‘no worries’ in French, and this ethos pervades its boisterous, boozy environment.

Smack-dab in Pigalle, the bar is well-trafficked and a perfect pre-destination hang at which to make an appearance before hitting up late-night parties at the nearby Chez Moune or Le Bus Palladium. You’re also welcome to remain, as Le Sans Souci doesn’t empty of its throngs until they’re kicked out. Later in the evening, the fun spills onto the sidewalks, resulting in a lively convergence of happily chatting chain-smokers.
