Unagi Kappo Ebisutei
A venerable eel kappo restaurant with about 100 years of history. 3 minutes' walk from Ageo Station East Exit. Traditional Japanese setting with private rooms, sunken kotatsu, and tatami rooms. Eel carefully grilled over charcoal using traditional methods. TripAdvisor #8 in Ageo. Online reservations available via Ikyu.com.
Tabelog 3.42 (156 reviews), TripAdvisor 4.2 (#8 in Ageo), Retty 3.87. Locals say 'The reliability of a 100-year institution' and 'If you want eel in Ageo, this is the only choice.' Unmatched formality and atmosphere.
