For poutine, this is my favourite place. Easily beats Smoke's aromatic offering. I don't know about the hotdog or burgers as I think it's insane not to order the large poutine.
Poutini's is pretty decent.
The fries are nice, chunky, and satisfies my body's need for grease. The gravy is thick, tasty, and well spread on the fries. The cheese is nice and creamy.
For seating, anywhere in Nathan Philips Square. Just be sure to kick the pigeons and seagulls out of the way first. Whatever you do, don't drop any fries or else they will all fly over to your area.
Would I drag a friend to this place?
Yes, I've done it before and will do it again. During the winter, I just be a man about the weather and tough it out while greedily munching my fries. I'll endure anything to get more of this delicious poutine inside my body.
