Mallang Gotgan is a takeout rice cake shop inside Gangneung Jungang Market selling castella injeolmi and mugwort, chocolate, and sundubu injeolmi. The premium castella injeolmi combines soft castella powder with chewy rice cake, and mugwort, chocolate, and sundubu versions are also available. Free samples of each flavor are offered before purchase, and everything is made and sold the same day, with weekend stock selling out by noon. There is no seating, so the shop is takeout only and nothing can be eaten inside.
