It must be something I ate.

Donkasu at Kimbab Cheonguk (trans. Kimbap Heaven) down the street from my place

It's a pork cutlet served with rice, salad, and corn (sometimes it's apples). It's also served with a bowl of some meat broth and kimchi, of course. This is probably one of my favorite dishes in Korea. I probably get it two or three times a week. It also helps that the kimbap place I usually go to is open 24 hours. Anyway, I can get donkasu at any kimbap restaurant.
