Music and goods exchange is over priced with bad condition generally since they closed the soul and dance and moved into that small space.
Music exchange in soho has a section of about 8 shite common albums and no 45s.
Selecta disc is new releases only.
Sounds of the universe is new release with a small selection or originals downstairs that are not particularly exciting, and they don't change that often, I've seen the same lps in there for 5 years+ unsold.
The only place left on berwick at is the reopened reckless records but it's a shadow of its former self.
Used to enjoy an hour or two wandering round nothing hill and soho, I don't usually bother going there at all anymore, it's a waste of time unless you are super lucky, which I've not been for a few years and nobody I know has either.
Flashback is worth a look but their 'filing system' is a bit odd, but nice people and you can turn stuff up, but you need to sent some time in there as there's a lot of tat. Be prepared to get on your knees and dig it's a good old fashioned record shop.
I'm afraid the days of finding gems in good condition at a reasonable price in Central London are mostly gone now, not surprising considering their rates and bills alone must be extortionate,
Sorry!
