Pigalle, SoPi, Montmartre: why the 9th has become Paris’s sweet quarter

Ten years ago, Pigalle mostly evoked red neon, late-night bars and tourists hunting cabarets. In 2025, it has become one of the most active Paris neighborhoods for new pastry, specialty coffee and dessert bars. This shift is called SoPi — South Pigalle — and it redraws the city’s sweet geography. Here is how the change happened, what you find there today, and why a crumble bar like Crumbles naturally settled in.

SoPi: what exactly is it?

SoPi (South of Pigalle) refers to the southeast quarter of the 9th arrondissement, roughly the triangle between Pigalle, Saint-Georges and Notre-Dame-de-Lorette. The term emerged in the early 2010s, popularized by lifestyle magazines like Le Bonbon and Time Out searching for a chicer name than "Pigalle". The area is still famous for its iconic cabarets (Moulin Rouge, Folies Bergère), but a new wave of openings is rewriting the script.

First cocktail bars (Lulu White, Glass, Dirty Dick) in the early 2010s, then neo-bistro restaurants (Pertinence, Bouillon Pigalle), then in the second half of the decade, coffee shops and pastry shops. Rue Pierre Fontaine, where Crumbles now sits, is one of the most transformed streets.

The specialty coffee boom in the 9th

Specialty coffee — meaning coffee whose origin, roast and brewing are controlled — exploded in Paris from 2015 onwards. The 9th was one of its epicenters. Tanat Coffee, the roaster partner of Crumbles, embodies this wave: Paris-based roasting, beans traceable from grower to cup, slow methods (V60, Aeropress, espresso). Today the 9th counts more than ten dedicated addresses.

For a coffee-shop neighborhood, the advantage is that it attracts a different audience than traditional cafés. The crowd skews young, urban, mixed tourist/local, willing to pay €4–6 for a quality latte. That same crowd appreciates counter desserts, creating natural ground for niche pastry shops.

The new Paris pastry: a favorable terrain

The 9th hosts several chefs and shops that are redefining contemporary Paris pastry. The neighborhood has welcomed Yann Couvreur (rue des Martyrs), Cédric Grolet has a nearby outlet, newer concepts like KL pastry or Genève éclairs are within walking distance. This density creates an ecosystem effect: a customer coming for Couvreur discovers Crumbles, and vice versa.

Dessert bars, still recent in France, ride this momentum. The concept centers on a single dessert (mochi, cookie, sweet dim sum, crumble) served at the counter, without the high-end staging of a traditional pastry shop. That is exactly the logic of Crumbles, the first crumble bar in Paris, opened in September 2025 at 3 Rue Pierre Fontaine.

Why a crumble bar settled in Pigalle

When Arnaud Vely, founder of Crumbles, scouted a location in 2024, he considered several neighborhoods: the 11th, the Marais, the 17th Batignolles. He eventually chose rue Pierre Fontaine for four reasons. First, foot traffic between Pigalle metro, Saint-Georges and rue des Martyrs is constant, day and evening. Second, the local audience is mixed (young Parisian professionals, tourists, students), well suited to a build-your-own affordable dessert.

Third, the immediate proximity to other gourmet addresses (rue des Martyrs is 200 meters away) creates natural weekend trails. Fourth, SoPi’s anchoring in lifestyle press (Sortiraparis, Paris Secret, Le Bonbon, L’Essentiel) guarantees editorial visibility from opening day — confirmed by ten-plus articles in September 2025 alone.

What to do in the area around Crumbles?

If you are planning a visit to Crumbles, you may as well discover the neighborhood. Five minutes on foot, rue des Martyrs lines up pastry shops, cheese shops, greengrocers, butchers — one of the liveliest commercial streets in Paris. Ten minutes south, rue Notre-Dame-de-Lorette descends toward the more bobo 9th with its concept stores. Fifteen minutes north, the Montmartre funicular climbs to the Sacré-Cœur Basilica and one of Paris’s most iconic views.

Museum-side, the Gustave Moreau Museum (rue La Rochefoucauld) and the Romantic Life Museum (rue Chaptal) are within walking range. For a specialty coffee after your crumble, several addresses are 5 minutes away: KB Café (rue des Martyrs), Le Bal Café, Lockwood. The neighborhood lends itself to a sweet-and-coffee afternoon route.
