This is kind of odd that I can answer this. I don't have a lot of experience in nail salons.
I did however notice one, and though it was odd for the area, which is why it stuck out. It's down by Wonderland Liqour in the same little shopping center. Which is at the intersection of Katella and Walnut(the street behind the DLH and PPH). I can't say it's still there today, but was at one point.
