I keep getting visitors (search engine referals) here looking for directions to Ikea in Birmingham, let me help you out:

Look for Wednesbury rather than Birmingham generally.
Junction 9 of the M6
Down the sliproad, turn left (if you're Northbound)
left again
follow the road under the bridge
right (ish) at the roundabout
It's a bit further up on the right.

Have a meatball for me.
