An eclectic mix of Italian, Greek and North American foods that can be served without compromising quality for quantity or speed.
It's one of the few spots I'd define a fast food that actually serve GOOD food at very reasonable prices. Their Alto Burger trio usually fills me up pretty well, and this comes from a proficient eater.
Alto is strategically placed close to the McGill campus, the ghetto, the residences and the downtown scene. Yet despite the surroundings, it is never full and you are guaranteed to find a seat even when the Montreal Canadians hockey team is playing.
The common sense with which Alto is run and their great quality for the prices charged would earn them four stars, yet one can't fail to mention their insanely late opening (and delivery) times and their proverbially fast delivery service.
What's more, delivery is free and I've never encountered a "minimum amount" barrier.
I hotly suggest their burger trios and their milkshakes. Pita dishes are OK if you fancy a quick bite but aren't too hungry. The poutine is a good effort, but the cheese is normal grated brick one rather than the traditional curds, so explore other parts of the menu.
It is the meeting point of the restaurant, the deli and the fast food joint. It runs like clockwork, the kitchen is always busy (indicating good grocery turnover) and if you order to deliver you will have your food extremely fast, wherever you are.
