This place deserves the 5-star rating that it has. My girlfriend's eyebrows have looked amazing every time she leaves here, beautiful before, and wven more beautiful after.
We've been here a few times so far and both Marci and Raji are very talented and good at what they do. Both have a fine attention to detail and they do it quite fast! It's well worth the $10 (+ tip) to get your eyebrows done here, and by the feedback I hear from my girlfriend this is the best place she's ever been to.
Making an appointment is not necessary, but is helpful. There are times when it can get quite busy, however, they are very fast so it's not so bad. There's a waiting area in the front (comfortable chairs!) and a TV in the corner that's usually showing an entertaining movie.
Customer service is excellent the moment you walk in. Usually a male is at the front counter to greet you and offer you some water. Aside from the eyebrow threading and all they do have merchandise for sale.
If you're a Las Vegas resident or even an out-of-towner, I highly recommend this place for eyebrow threading!
