Fairview has definitely improved over the last 5-10 years. The renovations also help a bit more. The tenants are the real reason for a mall to become "upscale", which Fairview doesn't have. They have got some better stores than what used to be there, but in order to achieve a higher status the renovations help to potentially attract them. The food court imo is now better than Yorkdale's.
I was briefly in Fairview recently, and I agree with you, the food court is better than Yorkdale's.
That's not saying much though: Yorkdale's food court is really poor. For such a successful mall, you'd think they'd have a roomier, brighter food court, but in reality it is incredibly noisy and crowded and the selection is not up to scratch.
