An awesome daytime activity to climb up the steep stairs (much faster) or take the long walk around to the top of the mountain. There is a great lookout spot at the top with an awesome view of the city.
We have no idea what is sold here, but if you google it we think it's something cool.
This is best middle eastern food in the world; Likely need a reservation.
A classic Montreal brunch spot with milkshakes that are worth the possible wait.
