Just visiting the location of American Graffiti is worthwhile - it's a quite magnificent museum of flash tattoo. The receptionists are friendly and welcoming, a bit harried, but that's understandable since AG is usually packed with people waiting to get tattooed. The artist I worked with, Scott, is outstanding. He's patient, takes his time, worked with me realistically when it came to prices, and the man is a genuinely brilliant artist and tattoo artist. I'm sorry he's leaving Sacramento, because it's our loss.
Pros: Ability of artists, environment, location, generally pleasant attitude
Cons: parking not too good
