Part of it is spicy, there must be Koreans who can't eat spicy food. So there are non-spicy foods.

Anyway, Korean dramas are not just for Koreans, and there are many countries that follow Korean dramas, so at least the dramas convey something of Korea's own traditions.

You can try the street fried rice cake, not expensive, that spiciness is appropriate if no problem.

Carp dumplings are filled with bean paste and are super cheap, but they don't get old.

Ramen = instant noodles, a better partner if you like kimchi.

There are also Chinese restaurants if you can't, but they are more expensive than local meals.
