Near Euljiro-3 station there is a tiny hidden alley full of pubs. These pubs all sell fried fish called “Nogari” for about 1000 won each. They also have fried chicken, tofu, fried rice, and octopus. News articles quote the restaurants as saying “it’s like Oktoberfest” but my friend and I were the only non Koreans there. That didn’t stop us from cruising through several dishes. I highly recommend.
