I highly recommend Au Festin de Babette for their brunch. Their selection of brunches is different than most other places. The one I usually go for includes a hot drink, a soup, a gratin dauphinois, two eggs Benedict, and a chocolate mousse. All of the items are excellent, especially the gratin dauphinois. This meal is usually very satisfying and cost less than $20 which is reasonable for good brunches in Montreal. The interior is very cute and feels homie and the service is usually good.
