Sangsun Naengjanggо in Seoul is a pork restaurant near Hongdae in Sangsu-dong that serves pork collar, samgyeopsal, and pork jowl. Staff grill the meat from start to finish and cook whole green onions and whole garlic alongside it. They check the griddle temperature with an infrared thermometer, then place the finished meat in a warming dish so it stays hot until the end of the meal. The wait is long, so there is a delay before eating.
