Pretty sure this place gets a lot more hype than it really deserves but it's still a decent place to go.
I've come with some friends with tattoos and have only once been really been blown away by the work.
I myself got my tongue pierced here and had a decent experience. No infections and everything healed nice.
I'm never a fan of places that ask for and pressure towards tipping. Of course I'm gonna tip you, you pulled my tongue out and pierced it! By asking for it you're only shorting yourself!!
