I stopped by on a lark while I was wandering around the mall today. I had a very short wait (around 5 minutes) before the aesthetician called me up to one of the service chairs. I showed her a picture of my eyebrows after a really good waxing job, she studied it for a few seconds, and then got to work. Threading can sting a little bit (the thread is pulling hairs out), but she used a very even pressure and offered several short breaks before moving to the next area. The redness subsided much faster than after a wax.
She finished in 6-7 minutes and the results were a perfect match for the photo. The pre-tip price ($16 for brows and upper lip) is a great value.
