My favorite massage parlor is called Tarawadee. Their prices are not as expensive as The Lord, but they are more expensive than other massage places on Ratchada Street. They are also considered as a high-end and classy place.
They have great quality girls, better than the Lord (my opinion), but you have to travel because it's not on Ratchada or Sukhumvit.
These girls who work in the high-end massage places, they move around, they don't stay in one place for a long time. They would go to work at a place that they can get paid better or up their rates. I saw a girl at The Lord last year who used to work at Tarawadee.
