This is a super-basic Tim's, located right near the airport. I've visited it a few times when I've been staying at the nearby Hampton Inn. It's pretty much just a drive through -- the inside area maybe has a counter to sit at, but I am not sure it even has that much -- it's probably better to use the drive through in any case.
Service is always friendly and they've never messed up an order.
This location is also notable as being the very first Tim Horton's I ever visited.
