Boucherie Union Square opened as the New York City flagship of the Boucherie group, bringing the warmth and energy of a traditional French boucherie — a butcher shop turned neighborhood gathering place — to the heart of Manhattan's Flatiron District at 225 Park Avenue South. The restaurant quickly earned a loyal following for its dedication to the craft of dry aging, with an in-house program that produces prime New York strips aged 21 days and grass-fed ribeyes aged 28 days, alongside access to rare Japanese A-5 Wagyu.
The menu reads like a love letter to the French culinary tradition: Soupe à l'Oignon and Les Escargots anchor the starters, while the mains travel from the humble comfort of Boeuf Bourguignon — available for one, two, or a table of four — to the grand spectacle of the 48-ounce Côte de Boeuf Pour Deux, carved tableside. The Charcuterie Bar, Fromage selections, and raw Fruits de Mer station all contribute to the brasserie's communal, abundance-forward spirit. Weekend brunch adds buttery croissants, Eggs Norwegian, French Toast, and Boucherie Waffles to the repertoire, alongside the popular Green Hour happy hour (daily, 2–7 PM) featuring $3 oysters and $14 cocktails at the bar.
Part of the broader Boucherie restaurant group with locations across the United States, the Union Square outpost holds a 4.7-star rating across thousands of reviews and is recognized as one of the city's premier destinations for French fine dining without the stuffiness. It is especially celebrated for delivering an authentic brasserie experience — marble-topped bars, exposed brick, and the buzz of a full dining room — that feels equally at home for a weeknight dinner, a business lunch, or a celebratory weekend feast.
