Chef on Call is the best delivery food in Montreal hands down. They deliver until 4am on weekends, their staff is really friendly, and the food always tastes fresh and of quality.
The sweet potato fries are amazing, and all of the dipping sauces are so good. Try the chicken tenders, any of the wraps, or even the light dishes like the Chic salad are a good choice. If you don't want pizza, Chef on call is the best option!
