Im going to add to numberonebigsizes post, and even up this debate a little

It is always the case that the customer has to clarify what he is paying for at all times - beforehand

What noubroz has found, is that even at Diamond Class level at a great place like Ginza, you have to clarify carefully what is included

The only mention of the subject of services on the website (where most newcomers find out about Ginza for the first time) is "All kinds of GFE & PSE".
What is not stated, which adds mystique to the place, is that services may vary, even at Diamond Class level

But the fun about Ginza is this mystery and finding out yourself which Class you like best !

What my own personal preference would be, is that the Diamond Class woman should do all the basics to totally satisfy the guy
And as far as I am concerned, the basics at such a "Diamond Class level" include DFK, GFE, CIM/COF/COB, and not finishing before the time allocated

Note that Greek or other more exotic expectations are NOT basic

We all have had GF and ex GFs who wont do CIM, so if Diamond Class level is no better than my ex GF, I wanna know beforehand

I would like to finish by saying Ginza is awesome, and I agree with all the posters saying the Manager does an absolutely fantastic job, and the ladies are superb
