Saiko Gyozabou (菜香餃子房)

Saiko Gyozabou is a tiny, six-seat counter-only gyoza and izakaya spot on a Kita-Senju drinking alley in Adachi-ku, Tokyo, serving handmade pan-fried dumplings and Chinese-style small plates to solo diners. It has a distinctive set of house rules — solo customers only, no reservations, cash only, a two-hour seating limit — and has repeatedly been honored on Tabelog’s Hyakumeiten lists, including the 2025 Izakaya EAST Top 100.
