I went with a girlfriend to do a ladies night out at Tranquil Waters and the experience was mediocre at best.
Even though they advertised "girls night out" as an evening event with hors d'ouevres and pedicures, the girls who did our nails were bitter and bored and wanted to get out of the place as soon as they could. We got there at 6pm and the hors d'ouevres (stale crackers and cheap cheese and old grapes) were almost all gone. While the interior was quite relaxing and attractive, the bikini wax I received as part of my supplemental service was not very thorough, and my friend had a similar experience with her eyebrow wax (a half-hearted job that left lots of stragglers).
The pedicures and manicures were fine but nothing extraordinary, and what took away from the experience - which should have been relaxing - was to be subject to the pedicurists' grumblings about how long they'd had to work and how they couldn't wait to go home. Then they had the audacity to say that they didn't provide manicures/pedicures in the way of "those Asian places" with as much disdain as they could.
Quite frankly I've had better manicures/pedicures at those "Asian places" and for less than this place charges.
If you're looking for a nice spa in the are, stick with Elayne White, Elizabeth Arden or Facing Thayer - all of which are beautiful, clean, relaxing and with less 'tude and cultural prejudice.
Pros: Nice decor, ample parking
Cons: Sub-standard services for the money, surly staff
