Save yourself the trip and wait for an appointment at Nu Nails across the street. I've given this place a chance several times, but cannot seem to get a great experience and have always felt rushed even when I've made an appointment.
I'm not too particular when it comes to my nails, but I do expect a decent pedi massage and with the SNS nails, I expect it to stay for 2+ weeks. This has not been my experience at ND Nails for either service.
Last time I was there for a pedi it was so warm inside my girlfriend and I were fanning ourselves. Add the warm temp along with the fact that this place is not well ventilated, and you'll choose the express service everytime.
Everyone is nice enough, but there are far better places nearby for the same cost, if not cheaper.
