The flavour of the falafel and of all the salads and sides are great. I enjoyed every bite of my vegetarian platter even though I felt a bit sick from the huge mount of garlic mayonnaise afterwards. Prices are probably unbeatable for Montreal too.
If I judged Boustan as a take-away restaurant only, I'd give them 5 stars. But if you want to sit in, you have to take away two stars unfortunately. Firstly, there's an air con blowing icy wind directly onto the dining tables. Secondly, the interior is very basic and not particularly inviting.
