I am really curious on how Ginza classes each girl into different levels. I have visited Diamond , Gold premium, Gold and even silver class.

It surely can't be the service level as 9 out 10 times you walk out with a smile on your face with all levels.

Looks? Possible, silver and gold levels are generally not as attractive as Gold Premium or Diamond levels.

Still the divide between Gold Premium and Diamond are debatable. My personal opinion are that some Gold Premium girls are even better looking than the Diamond girls.

Look forward to other punters opinions!
