Not understanding the hype of this place at all, I found La Banquise to be very mediocre. Montreal is known for hearty poutines, but I had much better experiences downtown back home in Toronto from food trucks... yes I'm not joking in the slightest.
Our order was the classic poutine, adding a plate of onions and a hamburger which we shared. The poutine was nothing special, lots of gravy and lots of cheese, however didn't wow us at all. Burger was nicely cooked. Onion rings were the worst, bland and extremely greasy.
With tip, our total was about $20 for two patrons which was pretty reasonable. No complaints about our server, received good customer service. Food was the shortfall unfortunately.
