Kimchi Jjim (Kimchi with tender steamed pork)
That's the dish on the left -- the world's most tender, melt-in-your-mouth pork, kimchi, and on the right a pot of kimchi stew. It seems like a lot of kimchi, but it's delicious. I could consume like 3 bowls of rice eating this.
The restaurant is 한옥집 (Hanok Jip) at Seodaemun Station, Line 5. Get out at exit 2, make a left at the Hana Bank, and a right at the Holly's coffee shop.
