Jabro did an interesting spot of research in a recent visit to Hong Kong, being sure to check out the numerous centres of otaku culture there, as well as plenty of more general sights. It does not look as if anyone with an interest in such things will have any difficulty finding what they are after in Hong Kong, not that this can be said to be surprising in the least.
As expected of a Chinese market… Chicken feet.
By all means see the rest; there isn’t a great deal which isn’t immediately comprehensible from the numerous photographs. Also see more general photographs here and here, and some particularly nice Hong Kong cityscapes here.
