Kamppi is a quite big mall and easy to reach since it's connected with the tram, local and long distance busses.
You can all kinds of shops from a kiosk to a high end clothing store. There are a couple of cosy bars and cafeterias as well as street food and fancy restaurants. You can find enough ramps and elevators for disable people and baby wagons. There are also lockers for baggage. I quite like this mall since you can find pretty much anything you need in it.
