Entrance is just around the corner on Drolet as you walk up Rue Rachel, building no. 4185... right next to a white residential car garage... not very conspicuous especially in the evening... and when it's located in the residential neighborhood. If you still can't find it, look for people waiting and standing on the sidewalk.
There is something about the ramen here at Yokato Yokabai... it was late, nearly closing time actually, and we couldn't help ourselves from devouring bowl after bowl of Tonkotsu ramen. Three bowls per person if someone was counting... were we hungry, maybe... was it that good, certainly... something in Canada's water that makes tasty ramen broth, who knows.
