Absolute best Gamjatang in town. I've tried many many places for it and Insadong is the best, hands down. Husband claims he could eat it everyday. Never disappoints and is always consistently good. The mains on the other hand are a hit or miss but most soups are very good. All you can eat is also very good. And lunch specials are a great deal as well.
Overall Insadong is our family's go to korean restaurant and we would rather take the time to visit here rather than have disappointing meal elsewhere.
