Gyeongju Issi is a Korean tavern in Seongsu, Seoul, serving jeon, bibim noodles, and traditional liquor. The food centers on jeon cooked to order, including minari shrimp jeon, potato spam jeon, eggplant jeon, and cabbage jeon. Seating is at the bar only, so the cooking happens directly in front of each seat as orders are placed. The traditional liquor selection is broad and includes options that are not sweet.
