I find that their smoked meat is very good, I recommend checking it out if it's your first time in Montreal and you would like to try some local food.
During my last visit, I ordered one of their steaks. I think it's called Hamburger Steak (I might be wrong). It is served with sauteed onions on top and comes with a side of French fries, veggies, a pickle and some gravy.
Portions are pretty big and food quality was also pretty awesome. Service was also good (the waitress was very nice to us).
The only thing that I didn't like was that it was very dark inside.
