I went there about 3 weeks ago for the first time. My nails were rugged.
As soon as I went in I was greeted and immediately dat in a chair. I told them I just wanted a fill and French tips. The woman talked me into getting the gel polish. She did an amazing job!! I told her I had acrylic nails (gel sort of freaks me out) and she was totally cool with it, she didn't try to talk me into doing something I didn't want.
My nails were so much smoother and Awesome after she got done. I did pay a little more than I was expecting ($34, rather than the $17 for a fill), but my nails were crap and she had to do some serious work. I definitely didn't mind paying that amount.
Even though Cobblestone is a little out of the way when I come to visit Phoenix I will definitely be coming back here!
