A favourite of mystery novelist Edogawa Ranpo, Tempura Hachimaki is located in the book district of Jinbocho. The space permeates with the aroma of sesame oil and a tendon only costs ¥1,200 (¥900 for lunch).
If you’re feeling flush, it’s worth upgrading to the ‘luxe’ conger eel and shrimp tendon. For ¥1,800 (¥1,700 for lunch on weekdays) you’ll get the aforementioned seafood plus an eel-flavoured rice cracker and two pieces of vegetable tempura.
