I stumbled in here after google maps had me going in circles in Vieux-Montreal looking for a place that had gluten free sandwiches etc. I was hungry, cold, and tired when I was lucky enough to walk by this place, scan the menu, and see they had brunch with gluten free pancakes. Came in, sat down, and a few minutes later, I had some coffee, gf pancakes with fresh fruit, and a reprieve from wandering around hungry and cold.
Not sure why it says it's closed on Sundays, but it's definitely open for brunch starting at 10am on weekends.
