I don't live in Manchester anymore, but if I did, I'd see indies or use GFE, which is basically Sandy's without the pretentious 'look at us, we're a professional business' shtick.
Sandy's really wasn't that special imo, yes it was well run at client level, obviously not so much behind the scenes as they fucked up in some way to attract Police attention, but the services were extremely rushed and formulaic and the girls, bar a few stunners, were no more attractive than those you'd find in any other parlour. The receptionists seemed to operate on a binary system of cold and overprofessional to rude and unprofessional and if you complained to Merv/Adrian Burch if anything went wrong he'd simply twist your words and try and discredit you, just read any forum thread on the other site containing Sandy's complaints and you'll see example after example of this. Proper twat of a bloke, I guess you can't expect anything else from a pimp though.
The fact it was so well regarded was mainly due to how crap most brothels in the UK are under the current legal system rather than them doing anything particularly groundbreaking. Just look at Germany to see the kind of places we could see if the Government ever legalise.
