We go out of our way to go here every time we visit Montreal (in fact we've booked hotels just so that they're within walking distance). It can get pretty crowded especially on weekends for brunch and it looks like it is very popular with locals. The decor and service are both wonderful, really cosy right in the heart of old montreal. I've been getting the egg-on-your-face sandwich (basically a panini with ham and cheese and a poached egg plus some sriracha on it) since I first went there five years ago. It has been consistently excellent as are all their pastries. Great selection of teas and coffees too.
