Meals prepared for kings are specifically called sura, and a table set with sura is called surasang(sang means a dining table in Korean). Sura is not a word of Korean origin. It is a Mongolian term that was introduced in the late Goryeo Dynasty when Goryeo was the country of the Mongolian king's son-in-law. Surasang was served twice a day: at ten o'clock in the morning and at five o'clock in the evening. A light snack was served around two o'clock in the afternoon rather than lunch. Early in the morning, a bowl of porridge was served, and it was called chojoban (early breakfast).
