Come with a big appetite. The poutines are quite large! There's a lot to choose from. One regular sized poutine would have been enough for my wife and I. The gravy was sweet. Cheese curds were firm and squeaky.
The place was packed. Popular choice. We sat outside. It was a very cool little secluded patio with many plants (fake but still nice to look at). Note that you can't have beer on the patio. Just indoors.
I would say the only thing we found was the bathrooms were gross. Walls covered in graffiti. Reminded me of an outhouse.
Also they only accept cash or Canadian debt cards.
Very cool area of Montreal.
