I'd probably say 3.5, but I'm rounding down because I probably wouldn't go back.
We stumbled into this place as we were wandering around Old Montreal, my boyfriend insisting he wanted to eat something authentic. To him that meant only french things or poutine, so here we were.
I honestly have no complaints about this place. The food I ordered was very good (assorted seafood baked in a lobster bisque sauce), the view overlooking Rue St. Paul and a bit of the bay was fantastic, and the service was prompt, polite and attentive. They also offer some of the cheapest bottles of wine I've ever seen in any restaurant ever.
The problem is that somehow the experience was lacking. Maybe it's because the restaurant was kind of empty. Not in a cozy romantic way, but in a way where you feel a little awkward that you're the only people in the room. Maybe because even though the service was good, it was also a little cold. Maybe its because even though everything was good, nothing wowed me (except those wine bottle prices!).
It's a perfectly good restaurant that I have no real interest in returning to. Make of that what you will.
