The only thing I have pierced are my ears and I'm really not that cool. I love Halo anyway. They have a fantastic jewelry selection not just for those with plugs or exotic piercings. Everyone here is always super friendly and helpful. I've come as the hand holding companion for numerous friends who have gotten pierced. I've always been impressed by the hygiene standards and knowledge of the piercing staff.
I also think their small museum collection of ancient piercings they've had over the years is pretty awesome.
