Please, for your own sake, try to go to this store on a weekday because come the weekend it is packed. Seriously you will wait a while in the queue!
This large, one floor open plan store has clothing for everyone at low low prices. It is very easy to get in and out of the store as it has entrances/​exits at both ends of the store.
If you have mobility problems, use a wheelchair or have a buggy I would suggest that again, aiming for a weekday will make things easier as by Saturday afternoon it looks like a clothing bomb has gone off and you will end up with wheels/​crutches tangled in clothes somebody decided should go on the floor instead of the shelves.
