Loup isn't a fancy restaurant but one with great atmosphere and good food. The deco is quite interesting, stuffed animals hanging on the walls, grilled chicken turning on the grill and a Dj mixing some tunes in the evenings (I went on Friday). Perfect warmup before hitting the city, not on an empty stomach!. Good address to put down for lunch or dinner if you find yourself in the first arrondissement and the great thing is, it's open every day. Bon appétit xxx
