I've never been to New York, though, I've been to London, Seuol, & Tokyo... I think they are all quite different in their own way. In Seuol, I remember all of the hills and mountains, and all the roads being very steep--- the shops were rarely very tall in the shopping district and there were a lot of non-Korean shops. In the underground stations there were always flower salesmen, and lots of shops...
London, it seems like everything has it's seperate place, from Camden, to Kennsington Highstreet, to Victoria Station, all linked by underground.
And last but not least, Tokyo, I remember when I first walked out of the station at Shibuya, and saw all the people milling around, looking bored, smoking their cigarettes, I thought it was one of the most vibrant places on earth. And as for the shops, absolutely all of them were Japanese.
Aaaaa memories.
