Gyoza dumplings are the specialty at this unpretentious counter shop inside the Joinus food hall. There's space for ten diners at two tightly packed counters, but most customers get their gyoza to go. Signature "Manten" gyoza, stuffed with juicy pork and chives, are the most popular item, but the rest of the menu is worth a try as well.
Other options on the rotating seasonal menu include Berkshire-pork gyoza, spicy fried-chicken gyoza, fragrant shiso gyoza and curry gyoza, and you can choose either regular dipping sauce (with optional chili oil) or miso-based sauce. Gyoza plates start at Y260, and you can add on rice and kimchi. Drinks include beer, "ginger highball" cocktails and three kinds of tea.
