While watching Corrie last night, I noticed something, the location Sophie was calling home from. It'd been used before, and quite recently too, as Cheryl's lap dancing club (the second one, where she only worked for a few days, not La Belle). Knowing the Corrie set quite well, I also know that it is very close by to where the old Davenports Garage used to be, which of course was under a viaduct - Which was the viaduct used for the original outdoor Corrie set!
