It's strange to find super authentic ethnic places in Madison, Wisconsin, but here is a PERFECT example. I went for dinner, which might not be as good as brunch, given the rest of these reviews...but it was still really enjoyable and a good experience!
It is a little pricey for dinner, but SO authentic! Cute little place (good for instagram pictures) with interesting seating. Definitely meant for an intimate lunch/dinner, I don't think it fits any more than 20 people inside. The waitress was super knowledgeable about the menu and the dishes were very unique.
If you're trying to find some authentic French food in Madison, this is DEFINITELY the place to go!
