I have been going to this place since moving out to Vegas from Los Angeles (about a year ago). I've had several different people do my eyebrows here but my favorite is Dippy! There are several locations around town but I don't mind doing the drive if Dippy is working at this location. Dippy is very nice, professional, takes her time and does an amazing job shaping quality brows.
I prefer getting my eyebrows threaded because it lasts longer and I avoid the burns, scabs and tenderness usually associated and comes with waxing.
Eyebrows R Us locations offer coupon cards and deals for unlimited threading a a year which could be really useful depending on how fast your eyebrows grow out.
*the place itself is not fancy, nor does not offer any spa like services, but they do great and shaping quality eyebrows* do not expect a fancy 5 star place! It's only $7.00 (plus tip) for the services. You get what you pay for!*
