A couple little birdies told me Luce’s chef, Dominique Crenn, was going to be opening her own project, Atelier, in the PlumpJack Cafe space, but I was told to keep my maw shut. No matter, since the word is now out: she is aiming to open ~ATELIER CRENN~ this December. Crenn will be offering a modern French prix-fixe menu (three courses for $55, five for $65, and a tasting menu for $95) that will allow diners to pick and choose dishes. Reportedly Nancy Nielsen will be designing the space with a European sensibility, with 40 seats in the dining room and 20 in the private dining room. In the meantime, Crenn will stay on at Luce during the transition. 3127 Fillmore St. at Greenwich.
