The signature is sesame oil pork kidney soup — the kidney sliced thick and generous, blanched with real precision: tender and juicy with no gamey smell, cooked to the exact right doneness, where one second longer turns it tough and one second short leaves it raw. The broth runs thick with sesame oil aroma, and the portion itself reads as unapologetically generous. The braised pork rice has a good fat-to-lean ratio and balanced saltiness, so many people order a plain soup alongside it. The menu also runs through pork heart, liver, and tripe as both plain and sesame-oil soups, making this a well-known offal soup specialist in Taipei. One Google reviewer wrote that they ordered sesame oil lean pork and sesame oil pork liver soup, adding, "Their braised pork rice never feels greasy, and the pork heart soup doesn't turn tough even after taking it home — impressive." Another mentioned arriving late and finding the kidney sold out, so it's worth going early.

A long-running soup stall in an alley off Songshan Road; the sign reads "Established in Year 62 [of the Republic]" — 1973 — putting it past the half-century mark. Open from late morning until 11pm, seats fill up fast during meal times and the dining area is on the tight side, so come prepared to wait.
