Hongdae sushi restaurant with brush-on soy sauce: Yu Iksang Sushi
Yu Iksang Sushi is a compact sushi restaurant near Hongdae Entrance Station in Mapo, Seoul. My girlfriend and I tried the 56,000-won Couple A Plus set, with generously long fish slices and aburi sushi. Verdict: a great pick for couples who want to sample lots of sushi styles.
