By Patrick HiegerWhat happens when a Michelin-starred Argentine chef returns home from his base in the South of France to cook a one-night-only meal? Magic, that’s what happens. On September 9, Mauro Colagreco will take to the stoves in his native Buenos Aires for an unforgettable, one-night only dinner with Germán Martitegui at his hidden palace Tegui in Palermo Hollywood. The evening’s menu will consist of five courses, as prepared together by the two giants of Argentine cuisine. The only drawback is that the dinner is exclusively for HSBC Premier clients, so you might want to check your bank account status if you’re thinking about going. Reservations can be made by calling 5291 3333. Don’t miss this.
