Togawa Sakae is a restaurant in a side street across from Sakae Parco in Nagoya, serving freshwater eel hitsumabushi. The eel is grilled over charcoal until crisp, then eaten with rice, mixed with nori and wasabi, or served as ochazuke with broth poured over it. Google reservations are available, so you can enter without a long wait. Travelers are sometimes directed to the second floor, where the seating is narrow.
