I go through Toronto airport frequently and this by far is the best food you'll find in an airport. Their steak frites are excellent and always satisfy. Be prepared to pay for it though as the prices are not cheap.
Nov/16 - Updating my review as this restaurant is not as good as it was when it first opened. They have changed the steak dish and their fries and neither are as good as they previously were. Had to remove a star and knock them down to 3 instead of 4.
