Fantastic store with helpful friendly staff. Sure there are some issues with the car park but at least you can get a space.
It really is just a first world problem that you may have to sit comfortably for a bit in your car. The end of the access road is shared from the roundabout by a big Sainsbury's so, on a Sunday with reduced trading hours there is a bit of a backlog to get out in the afternoon, just plan to go another day.

As far as Ikea goes it is clean bright well stocked and a credit to the team.
