This is a popular Lebanese restaurant at the southern entrance of the popular Crescent Street area of Montreal - the English-speaking side of the city's infamous partying street.
Boustan is really popular in the late night hours when people are pouring out onto Crescent Street around last call. They gorge themselves with shawarmas and kabobs which is excellent drunk food.
One thing you can order that's not on the menu is the "creation special" where they liberally add toppings like eggplant and potatoes to your sandwich.
Honestly, I don't find the quality to be that good. Boustan came highly recommended from a friend but I didn't find it to live up to the hype. The food just doesn't taste fresh nor is it very warm.
