HI,
Don't know if it is still there but comming from Tortosa you take the third exit from the roundabout this is for Mcdonalds and entrance for Carrefours, go pass both to r/bout take first exit and in the village on the main road on left hand side was a place that sold and cut glass. Its not far from Carrefours and could be worth a look.
Yours an uncertain Bulldog.
