Where was the Sun-Do Diner? What years was it in operation? I read someones' old post 2007 and they mentioned that name. I have a small tea saucer, with a horse head on it and it says Sun-Do Diner. I have been using it as a spoon-rest for the past 23 years. It was my grandmothers. I originally thought it had came from Elko, Navada when my mother and her friend went there to work after high school in 1963. Then when I read the post I had thought maybe it belonged to my grandfather and his brother, they had the Pool Hall in the 1950's and maybe they re-used plates from older restaurants that closed or bought new. I recently told my mother I had this plate, and she can't remember a Sun-Do Diner in Connellsville. Any information would help, thanks.
