THE BISTRO BUS: The Bistro Bus is the street arm of Delizios Bistro and Wine Bar, which is based on Main St in downtown Litleton. The theme of our truck ties in with our brick and mortar bistro and conveys imagery of a European bistro. Food offerings vary depending upon the event, and range from gourmet panini sandwiches and unique salad offerings to homemade soups, and even gelato and espresso.
