The tattoo shop is hard to find. If you try Google Maps, you won't unearth much. Once you do obtain the address (via Instagram Direct), you may still have trouble locating it - the building's exterior blends into the monochromatic ones surrounding it. When you finally enter, you'll be greeted by a loud buzz. And there, inside Secret Fire Tattoo, you'll find Hira Lupe and her wife, Laura, working. The influence of horror movies, Japanese comic books and Italian art are apparent in Lupe's work.
