Cards, you need to make an appointment
They accept cash and card, but there is a fee for card transactions. "Cash is King"! As for walkins I'd try contacting individual artists. They do however have a "get what you get machine" that is $100 for a random tat out of an actual gumball machine. Pretty neat if you're willing to take a gamble!!!!
Either cash or card is fine. I'd contact them to see if what you're looking for is something suited for walk-in services or appointment based services
