I grew up in the neighborhood and went to what used to be the elementary school around the corner on Old Orchard (I believe it's some business school or something now) and I can tell you that this place not only has a rich history with the neighborhood, but it has some of the best greasy food in the city.
If you feel like throwing calorie caution to the wind, then CHECK THIS PLACE OUT! Not only is it a part of Montreal history, but hockey history as well, being owned by the family of hockey player Sergio Momesso.
Great burgers, great subs, great fries, great everything! The prices are great and the staff is super friendly. A definite go to for anyone living or visiting the NDG area!
