A legendary fish izakaya tucked beneath the Yurakucho railway arches since 1946, run by Brit-owner Andy who hand-picks the catch at Toyosu Market each dawn.
★ Brown-rice (genmai) bread and gluten-free taiyaki
A dedicated gluten-free, rice-flour bakery counter in the basement of Shibuya Scramble Square, making breads, taiyaki and sweets with no wheat, additives or white sugar, and many items are vegan and dairy-free. It is a grab-and-go bakery rather than a sit-down meal, and as a dedicated GF facility cross-contamination risk is low though not certified celiac-safe.
★ The 'Zeitaku-don' bowl topped with tuna, uni and ikura, finished tableside as ochazuke with sea-bream dashi
A famous counter-only seafood-bowl shop where every bowl is fish over rice with no meat, so it suits pescatarians well; expect a queue, and note the soy sauce and dashi are not gluten-free.
