This was recommended to me by a friend who said it was the best pho in Montreal. I ordered the rare beef pho and some minced pork spring rolls. Both were delicate and flavored just right.
downsides:
It's small and cramped- you may get seated at a table in very close proximity to others and it is kind of a slog from the metro (uphill). Parking can be found on one of the side streets if you're driving and willing to walk a block or two. I think it is cash only so be prepared for that.
