Pierre Hermé

This macaron shop carries the name of pastry chef Pierre Hermé, who is nicknamed the "Picasso of pastry." Expect to spend a while agonizing over the flavors.

Although it's a Frenchman making traditional French sweets, he oddly opened in Tokyo first and came to Paris three years later. This shop is one of his first in Paris. It's small, so take your macarons to go and eat them in the Luxembourg Gardens a little later.

Good picks are the shop's signature raspberry with rose petals, chocolate passion fruit and pistachio. Pierre Hermé and Ladurée are the macaron shops visitors seek out most in Paris, and interestingly, Hermé once worked at both Fauchon and Ladurée. The downsides are the high prices and the line that's always there. Some prefer it to Ladurée for its slightly more complex flavors.

If you'd like to sit and relax, there is also a café. Close to our route, there's a branch in Bo Passage, home to the Certified Café we stopped by on the way to Saint-Thomas-d'Aquin. Links for café reservations and for booking macaron pickup are under "Learn more" at the bottom of the in-app script.

■ Getting to the next stop Our next stop is the church of Saint-Sulpice. With Pierre Hermé behind you, head down to the right until you reach an intersection. From there, Saint-Sulpice is visible at about 10 o'clock to your left. The church and Café de la Mairie, our extra recommendation, are separated by one small street, so take care crossing. It's about a one-minute walk.
