I'm not exactly sure the location it is in the airport but I think it's the Tim Hortons upstairs in a food court (up the escalators) by Montanna's. The service was poor. They were rude and couldn't understand a simple order. I clearly ordered a sausage and egg breakfast sandwich. When I got my order and opened it, I received a plain sandwich with only a sausage in it. I took it back and told them this was not my order. They had argued with me and said that's what I ordered. They did absolutely nothing about it.
It tasted so disgusting. I ended up throwing it out and got something much better on the other side where I needed to depart. I'll never go back to that one again for as long as I live.
(As far as I am concerned, they don't deserve even 1 star!!)
