This is my go-to place for nails in Madison. I've had my nails done here several times, and to be honest, all my friends in Madison go here too. Everyone is very friendly, and I've never had a an experience where someone is too rough or creates an uneven finish or anything like that. I feel like they take extra care to make sure that your nails are smooth and you really get pampered (paraffin!!). Always consistently good, which to me is a good sign.
I even brought my bridal party here to get their nails done before my big day. They got everyone through quickly (approximately 2 hours for six people to get pedicures and shellac manicures) and blocked the place off from walk-ins or other bookings to make sure we could get everyone done on time.
Highly recommend if you're looking for a nail salon in Madison!
