Across the street from Changdeokgong, we found a nice Korean restaurant. When you get Korean food, they will serve you these appetizers (bonchon), and you can then order what else you like. We got some bulbogi (marinated grilled beef) and bibimbap (rice with mixed seasonings, egg, vegetables, meat etc).
What's interesting is that with the bibimbap, you put in a raw egg and mix it. Hopefully, the dish is warm enough that the egg is cooked well enough by the time the mixing is done!
