Order the original apple pie with its 144-layer pastry, plus seasonal lab-only variations like fig walnut cream cheese or yogurt apple pie. Sagwadang started in Yesan, the apple-growing region of South Chungcheong, and this Mokdong branch is its first "bakery lab," running exclusive items the original shop does not carry. The location sits near Omokgyo Station across from Hyundai Department Store Mokdong. Open daily 08:00 to 22:00, with an unmanned vending window covering the overnight hours.
