Sarah did a cover on a small tattoo on my foot. It is amazing and I consider it way more than just a tattoo...an artistic creation that stays with me. They do take appointments (as a previous reviewer seem to be VERY determined to give Jester's a bad name) and I can only assume one would prefer to meet and discuss ideas with a potential customer. I am planning on going back to Sarah in the fall for another cover up.
Clean establishment (I've only been to South Side location), friendly well trained staff who are more than willing to answer questions. Check out their website and portfolios of the various tattoo artists.
