Got a shellac Mani here, and my mom got a regular mani and a shellac pedi. The girl did a good job on my cuticles, and the shellac application was even and carefully done. I will say that the end result came out a little streaky which is unfortunate, but I guess it was mostly due to the pale pink colour I chose. I asked her to do an extra coat on one finger which she did without complaint, but she didn't bother checking the rest of the fingers for a touchup - probably because there were waiting customers so she was a bit rushed. So that was a downside.
My mom did say that they do a really good job on the pedicures - lots of attention to smoothing down the soles of the feet and making sure calloused areas were given extra attention. She's a regular at this place, and her shellac mani and pedi always look good after.
