I'm not from the Great White North and I've only had a few Americanized versions of poutine- I wouldn't know if the version served here is legit or not. But I can tell you that it is good.
The snack-size traditional poutine is amply sized and priced ($6) for the name, and comes with fresh, skin-on fries topped with layers of fresh cheese curds and a splash of gravy. I do like that they layered the toppings so the bottom half of the order was not dry and boring. The fries were sauced just right so they were nicely soft but not soggy. Flavor in the gravy itself was lighter than expected but still savory and enjoyable.
Props for having vegetarian options available! I'd opt to stick to the namesake traditional poutine dish here over others, because the rest of the menu contains cheese-fry, chili-fry, and taco-themed concoctions that seem more on par with a bar or fast food restaurant.
