Zlatni Vrtic is an excellent and cheap restaurant in the center of Zadar, on the main street of the fascinating working class district of Varos. The waiters will call out to you from across the street (usually the sure sign of a tourist-trap), but once you enter you find a beautiful shaded courtyard with a genuine local vibe. If you want something light, they serve great soups and the mussels in tomato sauce were excellent. The only drawback was the service. Too slow and the waiters a bit clueless.
