The service, quality, and price of this student favorite make it worth the four stars. I've been to Chef on Call multiple times and have never left disappointed. Their Penne Arrabbiata is amazing and only $10 (plus tax) with the walk in special which includes a canned drink. To be fair, it isn't culinarily exotic or the most flavorful food in the world, but the consistency of great service, good food, and price make it worth a visit. If you're in Montreal as a tourist I recommend going elsewhere but for students, and residents this is a terrific place for a quick and quality meal. Note, they offer free, and in my experience rapid delivery within the downtown area.
