Here's a quickie list with the cheapest level girl:
Black Caviar (4000THB) is always good. Pricier, but worth the quality.
La Belle (2700THB) used to be my go-to. They had top quality girls and really nice rooms. I went twice post-covid and left because of no options.
Emmanuelle (1900THB) post-covid is now my go-to. I feel like girls migrated there when other spas closed. They have the most selection from what I've seen. The rooms are meh, but they all have bathtubs for soapy.
Alaina (1900THB) is and was always a piece of shit! I sometimes stop by there on my way to Emmanuelle -- just in case. Not really "high end."
Maria (5100THB) is AWESOME, but pricey. BUT AWESOME!!! High end, VIP, classy.
Tara (4900THB) renovated and doubled their prices. I haven't been because 4900 STARTING is way too much for me. But I think they're going for high end market now.
Little Duck: I haven't been, but friends say it's so-so, though they always found someone. In the old Nataree spot (RIP)
The Office (2300THB) it was good, but I went pre-covid
The Bank (2300THB) it was good, I went pre-covid
