I highly dislike this place. Located in the middle of the McGill ghetto, it is a local Montreal style diner that serves late night food to a huge student population. It is very popular amongst students but I really don't understand why.
Their poutines are made with soggy fries, shredded cheese (no cheese curds!!!) and a very bland sauce. Their pizzas tastes like store bought pizza dough with some vegetables and processed meat added to it. I have yet to have something that tastes good from Alto. I definitely do not recommend, if you are craving late night food, you are better off with chef on call down the street.
