Vito's Lotsa Pasta Truck in Hoboken, N.J., operated by a full-time police officer, has people pulling over for its build-your-own pasta dishes, cooked to order on the truck. Next, lunch customers dig in at Clover Food Lab in Boston. This mobile truck serving no-meat pita sandwiches, salads, rosemary French fries and blended fruit juices does not advertise the fact that they do not serve meat -- and customers do not mind that some of the town's best comfort food is vegetarian. Then, a trip to the World Fare BUStaurant, a mobile double-decker bus in Los Angeles satisfies lunch-goers with its South African inspired dishes. Finally, Vancouver, B.C., Canada's first mobile gourmet food truck, the Roaming Dragon, serves Pan-Asian fare with a West Coast influence. With dishes like pork belly sliders, fried rice balls, chicken kaarage and house-made lemonades, customers are following its lead.
