Bibiri is a self-serve buffet in Hongdae where you eat bibimbap and cup ramen without limit. You fill your bowl with as much rice, basic vegetables, and side dishes as you want, then choose gochujang or doenjang sauce and mix it in. You order at the ticket machine at the entrance, pick a fully cooked or soft-boiled egg, and help yourself to soup, danmuji, and kimchi. Mild sauces and guidance for foreign customers are available, but the basement space is not fancy.
