Where can I find any stuff with superheroes in Taipei? (like for example: Batman )
I’ve seen Batman T-shirts, but most of them are kid-sized. But you may try around Ximen: it seems there are plenty of geeky stores around. If you can’t find them, as a last resort you can order them online. I recently ordered some geeky stuff from Thinkgeek, and they sent it really fast. The custom’s fees and taxes are another matter, though.
