After moving to Toronto 6 months ago, my girlfriend and I have frequented Nuit Social at least a dozen times. One of the best places in the city by far because of its amazing food, but more importantly, its amazing service. As Montrealers, we have admittedly high standards (we've been so spoiled with great cuisine for so long). Nuit Social would fit perfectly in the Montreal scene. Do yourself a favour and give it a try!
Also, the ribs are out of this world. Tess is cool too.
