I probably won't be adding anything new to what's been said about this place - but wanted to add my two cents.
The steak and frites is to die for!! It's one of those things one MUST try while in Montreal!
This is one of those places where they pay careful attention to detail and everything, from appetizers, to main course to dessert are delightful.
Reservations are essential. Call a couple of days in advance and if you're planning to visit on Saturday - reserve a week prior!.
Can't wait to come back here next time I'm in town!
