This weekend I took my husband to the last place any self-respecting husband ever wants to go with his wife–the mall. But not just any mall. We went to the biggest mall in the whole world. Shinsegae Centumcity is located in downtown Busan Korea, a port city and the second largest city of Korea. It has been in the Guinness Book of World Records as the largest retail space since its construction in 2009.
