After a morning of climbing the stairs to the Sacré-Cœur and exploring the hilly streets of this former village, I was ready to relax and have a good meal. I turned to food blogs to help differentiate between was seems to be rows of interchangeable cafes in the area and came across this gem. 
Miroir has a traditional bistro feel with a modern edge. The fixed price lunch menu is a great deal at €19.50 and includes the main dish, a glass of wine, coffee, and dessert. More importantly though, the quality of the food was excellent. I had the lamb with roasted vegetables, which was tender and delicious. Dessert was an assortment of warm mini pastries, chocolate mousse, and an espresso, all of which were good.
I can't speak to the prior reviews, but I had no problem with the service (and I don't speak French). I left full and happy- overall, a solid choice near Sacre-Cœur!
