Gamasot Sirakguk in Seoho Market, Tongyeong serves sirakguk made by simmering eel. Add chives, Cheongyang peppers, green onions, and sancho powder to the broth to taste, and serve yourself from the side dishes. The restaurant opens early but closes early, and lines can form during mealtimes; seats turn over quickly. Sirakguk has a taste and aroma similar to chueotang, which can be divisive.
