Patate Mallette isn't some simple roadside eatery you happen to stop at when you want a snack. Patate Mallette is the destination. It's small, but the Beauharnois eatery has gained a reputation for slinging some of the best poutine in the province, a reputation held since it opened in 1956. Just make sure to only head here during the warmer months, as it closes up shop during the winter.
The small town of Lachute may not be much of a tourist destination, but plenty of Montrealers head to the little hamlet solely for the poutines at Restaurant Labelle. Affectionately referred to as “Labelles” by folks who know and love the small truck-stop-esque eatery, the poutines served here achieve a near-perfect ratio of cheese, fries, and gravy, in portions that aren't too big nor too small.
