I have been coming here regularly for the past year or so (only just started checking in...shame on me) . If you are not familiar with the location, it is located on Ft Apache and Tropicana directly behind the KFC.
They take walk-ins but you can make an appointment too. I would highly recommend an appointment if you plan to be there on a Saturday afternoon. Otherwise the wait time is anywhere from zero to ten minutes.
The ladies who do the threading are great... even though the staff has changed a little throughout the year, the threading is still consistent. I have also never paid more than $7.00 for eyebrow threading. As long as I am still on this side of town I will continue to this location
