Tantei

Perched on the 2F of a commercial building in Asagaya-Minami, Tantei provides a relaxed space to settle in for grilled beef tongue and homestyle set meals. The house specialty pairs savory, richly seasoned grilled tongue with barley rice and clear oxtail soup; diners with hearty appetites will also appreciate that refills of barley rice are offered with the teishoku.

The menu features the eponymous Tantei Teishoku alongside options such as the Yuchan Teishoku and fried chicken sets accompanied by grated yam tororo. With mugitoro (barley rice with grated yam) as the anchor, choices extend from beef tongue to grilled fish and small side dishes, making it easy to lean toward meat or choose lighter seafood depending on the day. Regulars are often seen tucking into bowls of Japanese curry, underscoring the approachable, everyday diner appeal.

The setting works equally well for solo meals at lunch or dinner, as it does for unwinding over draft beer and a few easy snacks around the table.
