Every time I visit Montreal, I go to Bistro Florin. The owner(s) are indeed from France and are now in Montreal by way of here and there. This restaurant is truly amazing for the following reasons. There is a shaded outdoor patio for summer dining. During the summer, reservations for the patio are a must. But there is usually interior seating inside at all times of year. Even though every single dish on the menu is amazingly delicious, the prices are reasonable for what you get. You can have a delicious soup such as vichyssoise plus an appetizer including their fabulous "La creme brulee au foie gras", a main course (often including a duck preparation and one or two of the main courses always include an optional fois gras accompaniment), and a desert (a frozen nougat cake on my last summer visit, yum) for $40.00 U.S per person. Apportez votre vin (Bring your own wine.)
The menu changes frequently, if not daily. They are also open for lunch with slightly smaller portions and of course priced inexpensively.
I found this little place on my own and then took my Montreal friends there. They could not believe that I had found such a jewel of an authentic country French restaurant without anyone's recommendation. They now attend this gastronome of gustatory delights at least once a month. LOL.
