Why don't you visit some and find out for yourself? But as the girls rotate, might have to go to the same one every day until the the first you saw?
You got a couple in Upminster and a couple in Elm Park where could try. Hope you bank balance is big enough as this is gonna costalot. Then you can post a review of it.
And for the record, yes I did get it at one out of the four. But that's for you to find out where???
