everyone was nice and professional. The shop felt a bit stuffy and the air was heavy with chemical smell, I think they need better ventilation and they needed us to wash our hands at sinks pushed up against the pedicure chairs it felt awkward to stand so close to the other clients to wash my hands. My nails turned out great, a lil more sensitive than usual but the shape is perfect and the length is even.

Came here on a whim and couldn’t be more pleased. All the workers are friendly and helpful. I’m pretty detail oriented about my nails, toes not so much. But they’ve done great work. The entire pedicure process seems much better than other nail salons I’ve been to as well. Highly recommend this nail shop!

First time coming here today and I will definitely be back! Great service, standard pricing and I love that they have an online booking system.

I’ve noticed a lot of salons lately will do your manicure while also doing your pedicure to save on time but personally I like doing one after the other to relax and enjoy the experience. I loved that they did my pedicure first then my manicure next!!
