If you want to eat salmon in Korea, this is the place to go.

A great salmon restaurant located in Yeonnam-dong, near Hongik University Station. The restaurant is called 'Yeoneoropda(연어롭다)'. I went around 6 PM on a weekday and was barely able to get the last table. Since a line forms right after, I recommend going early. The salmon was incredibly fresh, and all the various salmon dishes were delicious. It's also a great atmosphere for a drink, so it would be nice to have it with some alcohol.
