Gukje market is like a regular traditional market, you can buy clothes, kimchi dishes, raw things, and also food. I found this market is quite big with many branch alleys. Here is famous with 팥죽 patjuk, or korean bean porridge, and 빙수 bingsu, or korean ice flakes but since we were not in a mood of those 2 dishes we just did windows shopping
And then we got interested in a shop sells, 자몽쥬스 grape fruit juice. It costs ₩4000, so fresh and they also put grape fruit pulpy inside YUM!
