As a general rule, restaurants housed in broken-down busses are superb. Curtis’s Barbecue of Vermont is one good example. At the other end of the continent in the province of Alberta, Rocky’s Burger Bus is example #2. A 1960s-era urban transit bus long ago run aground in an industrial park at the southeast edge of Calgary, Rocky’s serves some of the best burgers in the West. There’s no indoor dining room here. Dining facilities are nothing more than a few scattered-around picnic tables painted red to match the bus.
