Saiko Gyoza Bo is a tiny, six-seat counter in Senju that has earned a cult following for its food and its famously exacting owner. The main event is the pan-fried gyoza, handmade with a thick, chewy skin that becomes perfectly crisp on the bottom, encasing a juicy pork filling. They are served with a prescribed tasting ritual to best appreciate their flavour and texture.
Beyond the dumplings, the menu features a short but refined list of Shanghai-style small plates. Reviewers consistently praise the oysters marinated in Shaoxing wine (be sure to drink the flavourful broth), the delicate Shanghai wontons, and other homemade sides like smoked tofu and sand gizzard marinated in oil. The playful house drinks, like the 'awawa' (a shochu highball with beer foam), are also a signature.
This is a place with a very specific character. Visitors should be aware of the strict house rules, which are enforced without exception by the owner. The izakaya is primarily for solo diners, it must be your first stop of the evening, and an order of alcohol and an appetizer is mandatory. Some guests report being turned away or spoken to abruptly for not adhering to the code. For those who fit the rhythm of the house, the reward is a convivial atmosphere and truly outstanding food.
Reviewers find the prices to be excellent value for the quality. A plate of five gyoza was recently around ¥650–¥700, with Shaoxing oysters at ¥700. A satisfying meal typically costs between ¥3,000 and ¥3,900.
