Had a great time here with a large group! We had 16 and they gave us essentially a set course meal for $20CAD a person (they quoted $25 but it seems to be a flexible number and they will adjust the contents of the meal accordingly)
Their hummus was alright, but their baba gnoush was fantastic! They gave us as much pita as we wanted too. In general, everything was fantastic, they accommodated our large group perfectly, and adjusted to our vegetarian's needs as well. It was a good mix of meat and non-meat courses, and by the end, everyone felt stuffed. The communal feel of the meal was also fantastic, with 4 people sharing a large set of food
If you are in downtown Montreal with a big group, definitely recommend calling ahead and booking here
