This mall is a good place to kill time. For example, if you're meeting a friend who notoriously unpunctual, you can chill out at Indigo.
There's also a food court on the lower level with tv's tuned in to CP24. Sushi Shop offers a small discount near closing time.
The grocery store often has long line ups and some pretty disillusioned staff, but the location is very convenient, with direct access to the subway.
