I have been to this particular location for eyebrow threading twice.  On both occasions I walked in without an appointment and was greeting right away.  There was no wait and the desk attendant was very professional.  The brow threading person did an excellent job.  I would recommend that she improve her customer service.  She did not ask me how I would like my brows done or even speak to me at all.  Overall, I would come back again since they did make my brows look great!
