Mastermind as a whole is extremely over priced in my opinion. Went in to get a few basic swirls added onto a piece and was charged $100. There was no shading. Just a few free handed lines he did. I was looking into getting a microphone from them, but they wanted $500 for something barely taking up any room on my forearm. Only a few of them guys in there are good, Jason being one of them. He's really friendly. One of the other guys, I think his name is Ron, is really rude.
The shop, though, is clean and they're open pretty late. They probably wouldn't be my first choice because of the prices, but some of the artists work is worth it, I guess.
