I'll talk about AMPS not girls, since they move around non stop. Most AMPS in west Dallas are quite clean.
The title for most upscale (FS) AMP with the nicest rooms, especially with the fabulous VIP suite , ( with the classy B&W movie star photos) there is no doubt in my mind goes to Pearls of Asia. You need to check the cheerleaders stats but Lisa is a sure bet.
The cleanest, tidiest, relaxing ambiance (and no trace smoking ) I experienced as of late, is Palace Therapy. Sue is a sure bet.
