Nana Plaza and outside Thermae
I went to Whisky & GoGo in Nana Plaza just for a drink. Very little girls dancing (1-2) as every other girl (5-6) was drinking with costumers. It seems with just 1 ladydrink they would stay with customer quite long (the full 30 mins I was there at least), but the cute ones were already taken at 10:30 pm so I just did drink alone. Only bad point is that outside and inside they have many signs advertising beers at 99 bath but the bill was 150 b.
Outside Thermae after closing time (11:30 pm), I was quoted 2 k and 2.5 k plus the expensive hotel upstairs from 2 of the cutest / younger girls (I didn't try to offer less and they didn't too when I started walking away). Few days before a good looking but a bit older girl asked 1.5 k and quickly decreased to 1 k when I didn't accept straight away her first offer. I guess the best looking ones still have no problem finding customers. (as I left, one of them actually walked the same way with her friends to Soi Cowboy and entered Penny Black).
