I have been there a few times. One visit was with Taiwanese Lisa, 45 minute visit good massage and good flip. No tip amount discussed, just total slurpy bliss. Left very satisfied with service and I tipped at $80. Look forward to repeat.
Lisa was off work so I tried Mimi, half Korean and Chinese. Was expecting service level comparable to Lisa. It was a flop of half and hour. Poor massage, half ass body slide, no linguistic skills, not very handy. Would not see her again. Would not recommend.
Sherry (I think that was her name, white girl, per-negotiated likes and service level. Delivered with a great attitude. Will go back.
There is another Korean girl Rachael, next on my list and if I get adventurous I will try Maya a black girl full size girl.
Always remember YMMV.
