Easiest route is go to the end of the highway and turn left. Cross 3 sets of traffic lights until you get to the roundabout by Debenhams/Paphiakos Stadium and go straight across.
Cross one more set of lights and when you get to the next (smaller) roundabout turn right.
Keep going straight along this road (it will be several kilometres) across all the sets of lights, past the King's Avenue Mall, along the new section of road. Eventually you will see Lidl on your right. Just after that is Capital Coast on your left.
Simples!
PS If you search on the Lidl web site for their Tombs of The Kings branch, the map will show you where it is.
