This vintage diner sits on an intersection that has been described as a 'dog's breakfast'. A main throughway into Toronto that sees heavy amounts of traffic, but lined with parking lots and vacant buildings.

I cannot find any info about the diner, only small mentions like in the above linked article. It has been abandoned and boarded on google street view, as far back as street view goes (2009). From a view things I saw inside and the decor, I think it closed in the late 1980s or early 1990s but it is hard to tell.
I really prefer to have some background information about explores and the history, but this one is very cool without it! Outside of some things left by other explorers (a birthday cake, names left on the displays, etc) it has been left the same as the day it closed!
