It was common belief in Japan until recently that McDonald's was a local thing only.
They really dont care much for other people or cultures.
I've never really understood the fasination with going there myself. I mean what are the chances your going to find a random Japanese girl whos all coy and sexily clumsly like in anime? Probably close to zero, besides, even if you do find one, who says that the girl is going to be into a foregner with a fetish?
I kinda get going for some food, like, really authentic food (not pocky, I can get that on the interent) I would go for that, but nothing else.
I dont read kanji, it would suck getting a manga in Japanese =/
Ah well if you want to go, I'm not stopping you, it might be worth the experience, but I'm fine sticking to manga and anime.
