Native Korean living in Korea here. Many restaraunts in South Korea have self-bars where you can refill the kimchi (and other various banchan (side dish) assortments) as much as you want - and in the rest of the places that don't have this you can just ask the waiter to give some more for free instead! Refusing to give free kimchi isn't just considered bad service here; it's just outright weird.

Only the "touristy" Korean restaraunts outside of the country don't do this - they charge hefty prices to innocuous side dishes like kimchi, and I've even heard places in Europe sell soju in shots (which is outright ridiculous, soju is one of the most cheap-ass low-brow artificially made commodity liquor here!)
