I am a huuuuge fan of "greasy spoon" old-timey diner restaurants. I love them. I love the classic eggs and sausage kind of breakfast, and I LOVE 24-hour diners, I love the shitty coffee and pour-out sugar dispensers.... but Fran's is the worst diner I've ever eaten at. The server wasn't nice, it didn't feel friendly (like you think a diner would), and the sausage was gross... and I'm one of those people who never complains about anything at a restaurant.
I think Fran's is a completely overrated tourist attraction that is staying afloat by name alone. Maybe their other food items are better, but I don't think I'll ever go back to try. There are too many amazing diners in downtown Toronto that have never failed to give me acceptable breakfast.
