Hikari Udon is a neighborhood udon shop in Seoul that serves udon with fried dishes. Its menu includes cold udon and agalchi udon, along with sides such as inari sushi and fried shrimp. The agalchi udon comes in a soy-based broth with chili, topped with fried vegetables and Japanese-style karaage, and beer is served in a frozen cup. The noodles and broth lack a distinct character.
