Snow White, Tulip, Mango & Co.
When I'm in Bangkok I mostly avoid the go go scene nowadays. The price is high, but that's not my main problem. Many of the girls don't live up to their promises they gave in the bar, they cut the visit from long to short time, refuse to do this or that.
I never get this feeling when I'm visiting the massage shops in the Sukhumvit area. Snow White, Tulip, Mango always give a good service, many things included. Total damage is 800 bt for the shop and 1500 bt for the girl, she will happily accept and offer BBBJ, A and GFE. And she will do it with a smile.
Long time is available too, but don't go before 10 pm. Otherwise it's too expensive.
