Went many, many years ago. Awful place, a nightmare to enter without being seen. Two rooms (basic table with tissues), and a woman sitting behind a desk. Got a massage with HE, also had a punt from there but that was in a house slightly up the road which was better. (Venue not the punt)
Noticed the outside is currently undergoing a tidy up, but St. Peter's Road is a place I'd avoid during the day,let alone the evening.
Have you asked if the WG will actually be at the shop, as they did have a house up the road from there?
