First time I came here I ate the Best burger I've ever eaten in Canada. It was the Coca cola burger ($13). Juicy and pink. Perfectly cooked. Toasted yet soft bun. Wow!
I had a nice conversation with the server and cook as we all were shocked that the burger was made with Alberta Beef yet the best I had tasted in the country.
I came here again the next day after touring the Basilica and had the philly cheese steak. It was average at best. It was missing grilled peppers and mushrooms and hastily put together. -1 star. Two days later my wife flew in from Calgary and I took her here for lunch while visit Old Montreal. I had the Coca-cola burger again, and she got a chicken sandwich with poutine. The burger was overcooked and not the nice juicy pink, but instead average. My wife's food however was excellent especially the poutine. It had a maple flavor to it. Yum!
What I love most is that it is a cute little diner where the dress code is casual. I found most of the other places in the area with more than 3 stars were more upscale and I wasn't dressed for them being in shorts and a t-shirt having just explored old Montreal and walked/biked all day. Oh and for parking don't park in the next door rip off lot, just get street parking around the corner on a side street and walk in.
