I would say that the Greenspot is one of the biggest hidden gems in Montreal. This place has every single type of food you could imagine. The menu is huge and everything is so good. It has a very old school feel to it. The seating is very comfortable and you get to choose where you would like to be seated. The food comes very quickly and the staff are extremely friendly. I would recommend trying a poutine there as they seem to be the most popular item.
