Chelsea Market, that West Side beacon of gourmet foodstuffs (not to mention Posman Books and Anthropologie), lands its first barbershop this week. On March 21, Decatur & Sons (75 Ninth Ave., nr. 15th St.; 646-470-7288), helmed by third-generation scissorhands Thorin Decatur, will offer limited appointments leading up to its early-April launch. Expect all the trappings of other salons (reclaimed-wood stations, Ursa Major–stocked marble shelves, $45 straight-razor shaves), but with a more flexible booking policy. Unlike at F.S.C. Barber, where Decatur was a manager, you can call ahead—or just swing by when you’re done shopping the rest of the market’s crêpes and charcuterie.
