Restaurants count! Join in!
I already mentioned a few, but here are some more that come to mind
Golden Griddle - still around, but not in the city anymore
Salad King used to be in a building called the Empress Hotel on Gould that collapsed a number of years ago. It has since relocated to what used to be a dive bar called Reilly's I think on Yonge.
Dunn's deli on King
Katz's deli on Dufferin
Mexican place called Chi-chi's. There was one near Sherway Gardens in Etobicoke
Rol Sal on Spadina is still around for now, but I think they are closing down soon
Bright Pearl that was right across the street from Rol San. There were multiple Chinese restaurants over the years at that building on Spadina near Kensington Market. Good Luck I think was one of them.
