Gale's Snack Bar, 539 Eastern, at Carlaw, no phone
Not only is this east-side hole in the wall Toronto's oldest luncheonette, it's also the cheapest. Where else these days are you going to find a freshly roasted turkey sandwich with fries and mixed veg for $3.75? And that's tax-inclusive, too. Not only that, but when you order a slice of house-made raisin pie - a buck! - it comes with a side of culinary history.
