London Calling is just one of several food trucks anchored in a parking lot on Glenstone, but it is certainly the most visible and unexpected in this Ozark community. First you’ll see the bright red double-decker bus. It’s available for indoor seating the days when sitting outside on picnic tables is not a pleasant experience. The family that owns London Calling comes straight from the streets of London and offers authentic pasties, Shepherd’s Pie and sticky toffee pudding, among other treats.
