Akatsuka is an old izakaya in Sotokanda, Chiyoda City, a five-minute walk from Akihabara Station. It serves grilled fish set meals, sashimi, and kelp rolls, with fish dishes such as vinegared mackerel and nishikyo-yaki alongside draft beer and warm sake. The Showa-style interior fills from early in the day, and the counter seats run out quickly. The menu is not large.
