Namdaemun Hairtail Alley

"Similar to the grilled fish alley, but this time within Namdaemun Market, there’s a hairtail fish alley where you’ll find a number of restaurants serving a spicy hairtail (cutlassfish) chili stew. I had it for the first time on this trip to Seoul, and it’s now one of my favorite Korean dishes. Open hours: throughout lunch and early evening, probably best to go at lunch, and some restaurants are closed on Sunday."
