With signage inscribed by the younger brother of Puyi, the last emperor of the Qing Dynasty, circa 1921, this state-owned restaurant is a real treasure. Dark wood is a prominent decorative feature, while red tablecloths lend it a rustic, classic vibe. Since 1997, diners have been coming to the current location to enjoy its authentic, no-frills Huaiyang cooking, with dishes like scorched eel with garlic and soy. Only private rooms can be booked ahead.
