Her enthusiasm and curiosity, and that of her class, are what led her to establish Onggi, a modern Dupont circle oasis serving modern hansik, or Korean traditional food. Onggi, which is named after the earthenware vessels used to ferment, cook, and serve hansik, has three pillars to its menu: the first, a selection of lunch specials served with black bean tea, assorted banchan, jeon, and salad; the second, hanjeongsik, or multi-course meal, menus served with floral tea for the table; and the third, a menu of à-la-carte small bites and main meals available all day.
