The building at "No. 3, Aiguo East Road" was originally constructed as a prison warden's residence during the Japanese era and later served as the residence for the Deputy Warden of a prison after World War II. It is the last surviving building of its kind in the area, witnessing Taipei Prison's history alongside the remains of the Kin-Hua district. Now restored to its original charm, it has been transformed into Lepu Lounge, offering both cultural and culinary experiences.
