Live around downtown and want a simple piercing done

What places do good work, and preferably allow walk-ins?

I'm also open to experienced individuals someone may know. I don't know if I can just head to someone's place, or pay someone to come to me, but that'd be cool.

I just want it done without having to book between some slot or come back another day. If I ever thought I would get a piercing, I would've just picked up on information over time lol, but I didn't....

Let me know!!!
