I enjoyed a nice brunch with some girlfriends here last weekend! We arrived right as the restaurant opened, so we did not have to worry about a line, but there was definitely one once we left.
I had the Brunch de L'Atlantique, which is perfect for those who like smoked salmon. It included half of a Montreal bagel with smoked salmon and all of the fixings, smoked salmon and eggs, a smoked salmon cake, and salad greens. The bagel was delicious (as they always are in Montreal), and I quite liked the crispy flavorful salmon cake. I could have done without the eggs. It was certainly plenty of food for brunch.
The prices seemed a bit high, but I think worth it for the quantity and quality of food. I recommend!
