Okada (そば処おか田) is a beloved standing-soba counter in Nihonbashikodenmacho, known for honest, quick, and incredibly affordable buckwheat noodles under ¥1,000. Ordering is done via vending machine at the entrance — a classic Tokyo experience — before joining the fast-moving counter queue. Regulars favor the spring chrysanthemum tempura soba and the chilled eggplant tempura soba in large size. With over 300 reviews averaging 4.1 stars, it punches well above its humble price point.
