Salvatore Ferragamo, the grandson of the Italian shoe and leather-goods maker, says you’ll be hard-pressed to find any Ferragamo wares at Il Borro, a luxury hotel and resort in Tuscany owned by his family. “I try to keep the two businesses completely separate, to build on the brand equity on the two different projects,” he told us at an event for Relais & Châteaux, the association for world-class hotels of which Ferragamo has been named the 2013 ambassador. He toasted his new honor Wednesday night at Del Posto with R&C member chefs Daniel Humm from Eleven Madison Park, Marea’s Michael White and Del Posto’s Mark Ladner.
