4-5K for G club quality?.....

Hopeless, plain and simple.
Even me, having been a member at more than a few (existing and defunct) G clubs and Japanese clubs/lounges, could hardly get this price with my regulars who were willing to meet me outside the clubs.
(4-5k considering: usually 3k for the LT and some food + other gifts was the lowest I ever paid and it was with: a girl from the now defunct Champagne room, not even a G club, and a girl from the ex Ritz, St Moritz and I was a big regular customer)

If one wants really to pay 4-5k for G clubs quality: Then get yourself a membership, focus on a girl and then you might have her visit you before or after work and pay only 3-5k for the deed....but this takes time and is out of reach of a tourist who is there for only a few days or weeks.

Cheers
