I love this place!! They have a huge range of colours, the people are extremely friendly and pay attention to detail but it's extremely popular so if you go without an appointent, be prepared to wait.
I don't recommend this place if you're planning to get fake nails (bio gel etc). I sent my sister here, where she did get biogel nails, and she didn't like the outcome. I've actually never seen someone get fake nails here before - everyone goes for the more traditional, one colour nail.
