Just thought of two more in Munich:

- Der Lautenladen sells only lutes, Anatolian lutes to be precise.

- Almost next to it is the "Spy Shop". I don't know if real spooks buy there but you can take the name quite literally.

New York used to have a Spy Shop in the 80's. It sold all kinds of tiny cameras and listening devices and things. I never went, but the ads made it seem interesting.

There's still one there. I see them often in tourist/beach cities, presumably because kids are enticed by things like invisible ink (judging from their billboards).
