Yodobashi Akiba in Akihabara is like the Disneyland of electronics stores. It's a massive, multi-level wonderland filled with every gadget and gizmo you can imagine - from mobile phones to electric shavers. You could easily spend a whole day exploring its aisles, but watch out for the annoying theme song on repeat! I'm including this because of the top-floor restaurants that could appease the whole family.
