Be Advised - Call Ahead.
I was happy that this "shop" was near my home. However, when I arrived I found it to be a home in a residential neighborhood. I was hesitant to enter so I drove down the street. Then a car drove up and parked in front of the house and a woman entered. I felt more secure about going in so I parked. A sign was in the driveway asking that no one park there. All perfectly understandable. But then I approached the door and another sign. This one was not so friendly. It read,"Don't even think about knocking if I'm not expecting you". I then noticed that under the business sign it said, "By appointment only". I wish I had known that ahead of time. In any event, they didn't appear to need my business.
