The Japanese are good at these niche museums. I quite fancied the Instant Noodle Museum in Osaka, but my travelling companion couldn't be persuaded.

There are also some slightly more hedicational museums in Japan. A friend of mine went looking for the Penis Museum in Tokyo but couldn't find it. Having a quick Google, there seem to be a remarkable number of such establishments around the world.
