Super nice place; a little on the expensive side but worth it for the atmosphere. If you hate greasy poutine this is the place to get it! The fries are nice and crunchy and don't feel like they've been dipped in oil. In fact, you can get the poutine with smoked meat on top which is another Montreal must-try, and it's absolutely delicious! I've had both the chop-chop (smoked meat) and the pulled pork poutine. Both are great, though if you have to choose one, I'd say go for the smoked meat.
I've also had the cheesecake, which they say is "Montreal-style"... it's a bit more fluffy than typical cheesecake; worth a taste but very difficult to fit if you've had any of their huge main dishes!
