Yangsando Yeouido serves hitsumabushi, a Japanese freshwater eel rice dish, in Yeouido. Diners eat the eel and rice first, then mix in scallions, seaweed, and wasabi and pour in broth to finish it like ochazuke. The set comes with salad, miso soup, steamed egg, soba, and kimchi, and reservations are available through CatchTable. Prices are on the high side.
