I've been to this Club Tattoo a few times since moving to Vegas, it's one of the only things worth braving the weekend traffic and parking at Miracle Mile.
I went in a couple days ago because I needed assistance reinstalling a piece of jewelry and have trouble lining up the internally threaded ball with the post. It's kind of embarrassing for me but everyone on staff was kind and Lani helped me out.
Previously I've gone in to ogle jewelry and Chris has helped me pick out the pieces that would look best with placement, and has then helped me with installation, lol.
It's very comfortable here, physically, aesthetically, it's clean and everyone follows safe practices. They're professionals, and this is what matters the most.
