Nadai Unatoto Ueno Ten is an eel restaurant near Ueno Station that serves freshwater eel rice bowls and skewers. It offers the Unadon Double with thick, tender eel and special sauce, hitsumabushi, and a rolled egg set, with free extra rice on some menu items. On a weekday at 11 a.m., entry was immediate, while on a Saturday around noon the wait was about 10 minutes; there are second-floor seats and luggage storage. The hall is narrow and eel-grilling smoke does not vent well, so clothes can pick up a smoky smell.
