Back in August, Parisian pastry chef Cédric Grolet began teasing his plans to open a boulangerie on Instagram. By late October, when I happened to be in town, the storefront windows at 35 Avenue de l’Opéra were plastered with a larger-than-life photo of Grolet’s professional number two, Yohan Caron, as well as three other core team members: Ariitea Rossignol , Sebastien Morin, and Mathieu Serais (above, from left). The image—equal parts boy-band album art and Diesel ad—had been torn back in places, revealing a near total gut renovation within. What remained unseen? Cédric Grolet himself.
