Negiunagiya is an eel restaurant in Seoul that serves eel over rice and eel soba. Its unaju places a whole grilled eel on rice with sansho, gim, scallions, and wasabi, and can also be eaten as ochazuke. At lunch, when the shop is full, you can wait about 10 minutes in the waiting area next to the store. The eel is on the oily side, so a greasy feeling lingers after the meal.
