My PT Therapy, 38 St George's Walk
It was previously an audiovisual equipment shop called AV Zones photo, but this closed down some time in 2015 or 2016. The last time we definitely saw it open was in April 2015. As of May 2016 we hadn't seen it open for a while, though there was still stock inside and there was someone working at a computer. By November 2016 it had been emptied out photo.
(As of October 2012, the name of the shop wasn't actually displayed on the frontage — there was just a banner saying "TV, hi-fi, & disco gear sales" — but according to a member of staff, it was called A V Zones.)
