Unagiku Oozuka Honten is a small eel restaurant near Koshinzuka Station serving unaju and eel kabayaki. Its signature dish is a boneless eel kabayaki, with each bone removed one by one, served with Kanto-style steamed-grilled eel, liver soup, pickles, and two kinds of sansho. Because the eel is prepared and grilled after ordering, regular eel takes about 30 minutes, and the boneless dish requires a reservation. There are only a few tables, so the space is not large.
