After feasting on Persian kebabs and stews at this attractive restaurant in Richardson, we looked at each other and said, "What a find!" Zereshk Polo resembled a chicken kebab prepared with onions and saffron. The dish was topped with sauteed barberry, which tasted a bit like redcurrants and provided a sweet and slightly piquant counterpoint to the gently spiced chicken. Like most of the entrees, Zereshk Polo was accompanied by excellent saffron basmati rice. The stews, such as Ghormeh Sabzi--beef braised with dried Persian limes--are house specialties and all worth trying. Service was slow but gracious.
