MOZZA, the hotly anticipated pizzeria owned by Mario Batali, Nancy Silverton and Joe Bastianich, is still a week from opening, but apparently some sausage fans couldn't wait. Late on Oct. 28, someone broke into the restaurant and walked away with $700 of hand- crafted cured meats made by Batali's father, Armandino, at his Seattle business, Salumi. Then just two days later, a 13-pound imported Italian mortadella sausage also disappeared.
