Hi Lewis,
As Anne said Casanovas seems right (11 City Arcade).
I think it opened about 1982 and closed in about 1991.

It was run by Andrew Stewart Ford. He filed the company for bankruptcy in 1986 (this may have been where the 'Cane In Style' name came from, as it probably needed to change names to continue opperating???).
The shop next door was Carrick Travel agents in 1991 but became a Florist (Tomlinson Flower Company) shortly thereafter and remained so until recently (13 City Arcade).
