Myeongnan Sikdang is a Korean restaurant in the Seochon Tosokchon samgyetang alley that serves ochazuke and mentaiko onigiri. It seasons rice moistened with green tea water using mentaiko, and also offers mentaiko, spam and avocado onigiri. It is open only until lunch, and customers look at the receipt-shaped menu on the entrance wall, sit down, order, and register a waiting number to be notified of their turn through an app. There are only 13 seats, so the lunch wait is long.
