I came here the first time I visited Montreal and am back a second time with my family! The service was friendly and fast, and the small portion is already quite large. My family of four shared three small poutines.
The hand crushed potatoes are really good. We created our own poutine and added the red wine sauce. Definitely try this sauce! The pulled pork poutine was also good, but the julienne fries got really soggy really quickly since they were so thin. The Montrealer had smoked meat, one fried pickle, and Swiss cheese. It was good, but the least favorite of the three.
In general, this is a great place to go if you've never had poutine before.
