Been here many, many times throughout my university years at McGill. Most times the services are friendly, especially at night when it's not busy the workers seem super chill and they make small friendly conversations. Food was always good, better than all the other A&Ws in Montreal. Only bad experience is that one time the cashier seemed awfully inconvenienced by the fact that we wanted to replace one item with something else and obviously showed it. Never saw him again so all good :^)
