Glad you asked this question as I took a long hiatus from the walkups, but went to King Hing last week and then Fuji building yesterday. King Hing was very busy the girls ranging from $400 Thai girls to $800 Russians and then Chinese girls of $500-$600. It was a little bit annoying with so many other brothers.
Yesterday at Fuji, it was a bit of a disappointment and when I went into the lift the policeman was walking out from the 22nd floor. There were a whole host of Taiwanese girls for $700 but then also there was mainland Chinese girls, some of whom were really fit, but still 6 to 700. There was no Russians or European girls, interestingly enough there was a Thai girl who said she was a mixed American but then she said $800 which is ridiculous. Then from the fifth floor onwards there was a police cordan so I promptly left.
Overall, King Hing is better.
