Yeah, that place has been kinda on and off for a few years (if not more, but as long as I've been in Berkeley), and they look pretty shady to me. I'd stay away.
Additionally, I'd like to warn you if you don't know already that ZEBRA IS TERRIBLE. They quite simply DO NOT know what they are talking about (they advised me to stretch way too fast), as well as selling crap jewelry at huge markups. They are there to rip tourists and students off. You talk to a person at the counter about a piercing and then they give you a number; you don't even get to talk to the piercer about what you're doing until you're back in the room -- it's like an assembly line.
I've heard of people getting decent tattoos there, but I wouldn't risk it.
Industrial is on Dwight and Telegraph, like half a block away, and orders of magnitude better. They use all real, quality jewelry, know what they're talking about, and are very professional. Their tattoo work looks great too, though I don't have any. I swear by their piercing, though. Plus they have a lot of the jewelry BAF sells so you can see/buy it in person, as well.
