A Boston restaurateur adds a mobile arm to his operation this weekend. Philip Frattaroli of Ducali Pizzeria & Bar and Cunard Tavern will unveil his new Caffe Pellicano Mobile Espresso Bar at a festival in the North End near another of his family’s restaurants, Filippo Ristorante.

Caffe Pellicano tips its hat to the craft of Italian coffee in more ways than one. The truck is a vintage Piaggio Ape — a three-wheeled Italian truck — which Frattaroli had outfitted for the coffee operation. “If you think about coffee culture in the U.S., it’s all based on the Italian system of cappuccino and espresso,” he said, and he wanted Caffe Pellicano to hark back to that same Italian heritage.
