Sejong Traditional Market operates as a regular market. On the 4th, 9th, 14th, 19th, 24th, and 29th of each month, it transforms into a larger fifth-day market with an expanded selection of food and attractions. Visitors can find fresh vegetables, fruits, seafood, and everyday goods at affordable prices. Popular snacks include handmade mandu with a 50-year tradition, as well as jjajangmyeon (black bean sauce noodles) and syrup-filled pancakes with nuts, which often draw long lines.
