For the $20 tattoo Tuesday, do you recommend appointments, and are there any specific restrictions? (i.e. no color, smaller than 2 inches, etc)

Wow they have 20 dollar Tuesdays?

I'm not positive on the size but they have a few books full of tattoos for the $20 tattoo Tuesday. They're small but hey, its $20 lol they also have a bunch of $20 & $30 piercings that are about double that on any other day. As for appointments me and my friend never made one and we were seen almost immediately, but that was for the piercings. However, the 5-6 times we went it was never really packed. Just a few people sitting on the couches.
