It's fall again and to me that brings one thing to my mind -- white truffles! I know it's not quite tartufi season but I want to make reservations now for one of those pricey truffle dinners. Anyone been to one and have recommendations? I know certain restaurants generally have them: Delfina, Oliveto, Ristorante Milano, Palio D'Asti. Anyone eaten these dinners? Have a recommendation for another spot?
