Old Omppang House is a cheonggukjang restaurant in Deokjin-dong 1-ga, Deokjin-gu, Jeonju, across from Deokjin Park. It serves only cheonggukjang baekban, and once you sit down, cheonggukjang and steamed mackerel arrive according to the number of people. It is open only from 11 a.m. to 1 p.m. on weekdays, so customers who arrive late are turned away. It accepts parties of two or more and does not take card payments.
