Dr. Woo of the Shamrock Social Club in Hollywood is, currently, and pretty much for the foreseeable future, the most in-demand tattoo artist in the world. Part of it is his freakish eye for detail, sure. Or maybe it’s that the high-stakes, single-needle stuff requires the steady hands of a vascular surgeon. (I mean c’mon, look at this hamburger!) Either way, the dude’s art is unreal. It took a bit of Instagram lurking on our part, but it seems everyone from Zoe Kravitz to K-pop superstar G-Dragon to Albert Hammond Jr. of the Strokes (aka just the coolest people alive) has carved out some time with the good doctor.
