One of Manhattan’s favorite Italian eateries, Il Buco, is offering foodies and skiers a unique opportunity this winter to travel with its staff to Courchevel 1850 in the French Alps for a food-and-wine getaway. From January through March, Il Buco owner Donna Lennard and her husband, Luca Boniciolli, who is a private ski guide, will host groups of eight to 12 people in private chalets for one-week vacations that combine skiing, food, wine, and other activities.
