Stari Grad - Kneza Mihaila Ruski Car or Russian Tsar is a commercial-residential building and a restaurant in downtown Belgrade. The purpose of the building has not significantly changed since the erection: the residential area is on the upper floors, the business space in the mezzanine and the restaurant on the ground floor and in the basement. The name of the old, ground floor venue of "Ruski Car", which was demolished to make room for the new building, was kept. During the Interbellum, it was an elegant Belgrade restaurant, the meeting place for both noble citizens and the intellectual elite of that time. Arch. Petar Popović and Dragiša Brašovan
