I did a walk-in shellac manicure and was really pleasantly surprised with the results. The staff was very friendly and the shop was very clean - and quiet. There's a tv in front of the manicure station (as well as some of the pedicure stations), so you can watch some tv as the staff do your nails.
I'm no manicure aficionado (I get one occasionally), but I was very happy with my nails. I would definitely go back again (and plan to).
