How about a Korean BBQ grill set? Your dad can have his own at-home Korean BBQ experience. You could also consider getting him a subscription to a Korean snack or food box service so he can try new Korean snacks every month. Alternatively, you could book him a cooking class to learn how to make his favorite Korean dishes or buy him a cookbook filled with his favorite Korean recipes.
Or you can get him a star map with the date when he welcomed you in this world.
