I don't know much about bagels, but I came here because i heard it's the place to get montreal bagels if you are ever in montreal (other than fairmount)
I came around 12:30-1 and there was maybe 4 people in line. It was long after I paid though. It's amazing to see authentic bagels made; you see the huge dough pile and a baker cutting it and rolling it. The oven is in front of you and staff are very friendly. There's a wall with lots of newspaper articles with their history. There are fridges with lots of cream cheese options too.
I had a matzoh, which is a plain and crispy giant cracker. The flavourful is all from the sesame. Bought two dozen bagels. Bagels are nice and chewy, I guess it depends on your preference of bagels, but I like chewy foods.
