If you're coming from Zagreb after entering Sisak city limits (gas station on your left) keep driving straight after the first street-lights you reach and follow signs that direct to Kutina. Just before the bridge over Sava you'll notice the sign that directs you to the Stari grad Restaurant.

If you're coming from Popovača or Kutina after you enter Sisak and cross the bridge over Sava turn right on the first crossroads (follow the right-of-passage sign), take another right turn at the next street-lights and follow the road that leads to the Stari grad Restaurant.
