I flew into Montreal after a grueling month and was too tired to go out. So my wife and I ordered in Boustan. We got hummus, stuffed grape (vine) leaves, the falafel trio and the Shish Tawook (Chicken) trio. The garlic potatoes were excellent. The grape leaves were great and were covered in a tangy, mayo-like sauce that was really good. The hummus was OK and the pita it came with was a little hard and dry, but this was the main downside.
My falafel sandwich was pretty good. Not quite as good as my old favorite falafel stand in New York but still good. My wife really liked here Shish Tawook sandwich.
Also it was really cheap. We got all of this delivered for $25 (CAD) including tip. And there was a lot of food.
