The queue that forms along Newcastle Street is the first clue: people wait here for xiao long bao, and the kitchen makes them the slow way, pleating and steaming to order rather than holding trays under lamps. The soup dumpling is the house signature, a delicate parcel of meat and hot broth sealed in thin, hand-rolled dough, meant to be nicked with a first small bite so the soup can be drawn off before the whole is eaten. It is Shanghainese cooking treated as craft rather than volume, and the room runs at the brisk, unfussy tempo of a place that knows its trade. Beyond the dumplings sit the wider comforts of the Jiangnan table, and a second room has since opened north in Karrinyup for those who would rather not join the Northbridge crowd. There is nothing precious about the setting; the appeal is in the making, in the discipline of dough and filling and the few minutes of steam that separate a good soup dumpling from a broken one. Come early, expect to wait, and order more than you think you need.
