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.
Climb your way up the escalators to the 9th floor of the Printemps department store (the Beauté & Maison building) for possibly one of the best panoramic views of Paris. You can see pretty much everything from here and unlike the views from the Eiffel Tower you’re right in the middle of the city and can almost reach out and touch the monuments around you. Go up on a sunny afternoon and take a seat on one of the benches, lay down on the fake grass lawn or have a drink and a snack at the Deli-Ciel café.
