I have never been to 7 Cowper but recently had visited 45 George twice, both times had a pretty good punt and I will go back whenever I have the opportunities , the facilities are good, prices are cheap - round about the same price as RnT ! And both times I got super busty girls - all my boxes are ticked !
Only been to 22 once very long time ago with no booking, very posh venue but that day I ended up with a new girl on her first day who probably didn't want to be there and I found out later she didn't get to stay on anyway, so it was more bad luck to me than a bad punt, so for me 22 stays on my radar, just based on my belief that Roger is running a good show !
And I don't even go FS usually !
There you go, just try to give a balanced view on these shops !
Cheers
