Level:0 is tucked in the residential area behind Yongsan Station. The name of the joint has a double meaning: the first floor and the pursuit of zero-waste cooking focused on sustainability. Here, diners can enjoy their multi-course meals in a nomadic fashion as they wander from space to space. Committed to sustainable dining, the chef reuses leftover ingredients by drying them into powder or fermenting them. The establishment also sources its beef from organic farms. On the aesthetic side, its tarts in the shape of a finely manicured garden, and a dessert resembling the whole restaurant, are a delicate feast for the eyes as well as the palate. Since Level:0 adjusts reservations to avoid crowding, double-check with the restaurant before visiting.
