I got my nose piercing done here a year ago, and they were absolutely fantastic.
The staff was really helpful and friendly. I actually managed to scrape a sizeable chunk of skin off my ankle on my way down to the shop-a biking mishap-and when I got there they actually took me into one of the rooms and disinfected and wrapped up my ankle for me before my appointment.
As all the other reviews say, they are very professional, and very clean, and I have had no problems with my piercing or my jewelry. They are on the expensive side, but they product and services are absurdly good, so it's worth it!
