Kappabashi-dori is definitely worth a visit though: in addition to fake food, they have epic selections of Japanese ceramics and all sorts of kitchenware. It was originally mostly for wholesale quantities, but has become increasingly retail/tourist-friendly.

These stores around Asakusabashi are actually "show rooms" for national distribution networks.
