After North Korea our next stop was the second half of what used to be one country. But today it's a very different place.    I'm still traveling with my daughter, Clara, and we've arrived to South Korea. We've decided to visit two places in this country, but first another big city - the capital Seoul.    We meet one of the locals, Dong Mi Lee, Editor in Chief for Time Out Seoul for a talk about the country, the city, the people, K-pop and North Korea.
