How spicy is Korean food?
Korean food is actually not all that spicy, unlike what many people believe. I'm not saying people wouldn't find Korean food hot at all. It's just not the hottest in the world. (Mexican, Indian, and Thai are all spicier.)
A quick tip. If you think Kimchi is too spicy to eat, then don't try any other spicy food. Because if you do, it will feel like somebody is torching your tongue with a lighter. (And make sure you have plenty of milk around.)
