I always do the shellac manicure and they are very quick and the final result is really good. It normally lasts 2.5 - 3 weeks. I get bored of the nail colour before it starts looking funny. I literally only change it every 2 weeks because my nails grow super fast and because I get bored of the colour. They only take cash in the salon so if you want to pay by credit card use the app to pay. I definitely recommend them as I have been going there 2x per month for more than a year, but it's a bit pricey.
