This place is awesome on so many levels.
I'm not a poutine specialist, but for me the food tasted really good. You have a huge selection of "toppings" you can put on your potatoes. Portion sizes are generous for sure. There are premade options as well if you don't know what to get. There's even some $100 poutine dish that could probably feed 50 people! No kidding! My friend eats quite a lot of pouitine in different places and he also said the food's really good!
Service is excellent! We went with a group of 8 people. No problems making reservations, being seated, or getting our meals. The owner,Kosta, actually came and talked to us, and even gave us a special dish on the house. There was always someone around taking care of our orders. In the end we even got our deserts for free. That's exactly the kind of service I hope to receive at any place I go to.
Atmosphere is quite nice. I was expecting a fast food place when I heard of poutine. Couldn't be farther from truth. Music is good, even though a bit loud to my taste.
I'd definitely go back again, and probably visit their Montreal locations.
