I love Shila's! The location is convenient and 9 times out of 10 you don't have to wait too long. You can always call ahead and make an appointment and they will tell you how many people are currently waiting.
There's one lady whose there on Thursdays, I think it may be Shila.. I should know since I've been going there for almost 2 years but she is AMAZING! I just LOVE how she does my eyebrows!
It's $10 for brows however they always have check in specials and they also have a stamp card where you get a threading for free!
At the check out counter they sell various other things like colored contacts and accessories!
If you live in the Southwest area, Shila's is great!
