The MAC conference room is the 2nd blue building on the left of photo and this is where North and South meet at a table inside the room that has a North - South line down the middle of it. This is the only place where you can "technically" walk into North Korea. DPRK pavillion at the background of picture. Note the SK guard's stance. Unmoved and they wear very dark "aviator" style sunglasses to prevent eye contact with the North Korean counterparts. Photos taken from the Freedom House
