When I was a student, I went on an exchange program to Seoul, South Korea. There I fell in love with Korean cuisine and the restaurant Kimchi House in the centre of The Hague is a really nice restaurant with good Korean food. This can also be validated by the number of Asian people who eat at the restaurant (one of my teachers once said that a restaurant is good when it is visited by a lot of locals).
The restaurant is specialized in Korean barbecue and therefore, every table has its own grill. They offer separate dishes or all-you-can-eat. If you go for the all-you-can-eat version, you have two hours and you can order whatever you want from the menu. The menu includes many traditional Korean dishes, like tteokbokki, kimchi, naengmyeon, and different types of jeon. There are also different types of meat that you can grill at your table. The bulgogi is amazing and it is a nice place to eat with a group because it is shared dining and interactive, so it can double as an experience.
