Tipping is optional in Seoul and is generally not expected. In South Korea, service charges are often included in the bill at restaurants, hotels, and other service establishments, so there’s no need to leave an additional tip. In fact, attempting to tip might even be confusing or politely declined by the staff. However, if you receive exceptional service and want to show your appreciation, a small gesture, such as discreetly leaving a tip or offering a kind word, can be appreciated, though it’s unnecessary.
