The Snow White Grill in Winchester was built c. 1948. Snow White Grill was another burger chain, along the lines of Little Tavern, White Tower, or White Castle. They were in the West Virginia, Virginia, and Maryland Area. Interestingly, the Snow White Grills were designed by the same architect, Luther Reason Ray, of the Structural Porcelain Enamel company, who also designed the classic Little Taverns, as well as Hot Shoppes in the same area. This explains the obvious similarities in design and materials.
