Strawberry mousse with pistache cream inside, the Saya by Sadaharu Aoki is my favourite cake. Sadaharu Aoki have two patisseries in Paris, 35 Rue de Vaugirard near the Luxembourg park, and 56 Boulevard de Port Royal in the 5 arrondissement.
There's a few secondhand clothes stores in Paris, but always immaculately selected, expensive and fashionable. Guerrisol however is a huge, dirt cheap jumble sale. Stock seems to rotate daily in each of their four stores, and prices fluctuate on the hour. Sifting through endless rails of synthetic jackets at €3 can suddenly reveal a hidden gem.
Great place for coffee in the morning, delicious homy lunch, or a drink in the evening. It's a cosy neighborhood joint, with a fun crowd and vintage furnitures
