Soubois is excellent for its vibe and crowd. Soubois (as of September 2015) is the place to be seen, according to my Montreal based friends. On a Saturday night, the place was packed with great looking people. The cocktails were delicious and their wine offering was extensive. I easily found a few of my favorite reds on the list and devoured a bunch.
As for food, there are some dishes that seem to be better than others. I particularly enjoyed the decadent poutine (with foie gras, wild mushrooms, cheese curds and gravy). The seafood platter with oysters, crab cakes, mussles and clams were quite nice also. I was mixed on the charcuterie platter - while I thoroughly enjoyed the foie gras pate and cold cuts, I didn't enjoy the pickled peppers spread along the length of the platter - I felt like it detracted from the spread. I was also left mixed feeling about the mains. I had a mushroom spaghetti. The sauce, the mushrooms and spaghetti itself were pretty good. But the large dollop of mozzarella took away from the rest of the dish. The steaks that many others in my dining party ordered did not particularly look appealing to me either.
In any case, I would recommend this venue for a dinner and/or drinks for its very cool vibe!
