If I eat bagels, this is my spot as they have the best bagels in Montreal. They have several locations but my favorite is the original one on st-Viateur. When I am in the area, I stop by and grab a warm bagel (or more) and eat it right away while fresh. They also have a wide selection of spreads and cream cheese so you can eat on the spot.
If you're visiting Montreal or in the area, make sure to stop by and you will soon understand why his Montreal landmark is known for its bagels.
