Not up to date with the roster as I am out of circulation sorry but if it is extras service you seek look for the half japanese girl that goes by Emily/Aline depending on which shop she is at.
Does shifts at at least 2 or 3 different places including SBM.
Failing that check out the new short term J girls at SGM (Cathedral St) and Parra Blossom for the same reason. I think one of them does a shift at SBM (highly recommended by a good industry friend)
