I keep feeling like I'm doing something wrong at Korean restaurants?

Do not worry, most Koreans are very understanding with foreigners learning the ropes! Here are the key things that tripped me up at first. Side dishes called banchan are free and you can ask for refills anytime by saying 반찬 더 주세요 or just pointing at the empty dish. Water is self-service from the water dispenser in most restaurants, so do not wait for a server to bring it.

To call the server, press the bell button on the table or call out 저기요 (jeogiyo). It is not rude at all and is the normal way to get attention. Tipping does not exist in Korea so do not leave money on the table. You pay at the counter near the exit, not at your table. When eating with older Koreans, wait for the oldest person to start eating first. Do not lift your rice bowl off the table like in Japan or China because in Korea the bowl stays on the table and you eat with a spoon. When pouring drinks for someone older, use both hands as a sign of respect, and turn your head slightly to the side when drinking in front of elders. Lastly, do not stick your chopsticks upright in your rice because it resembles funeral rituals.
