Skewers of grilled lamb have replaced joysticks at the former address of the Fun Arcade in Metairie. In its place, Hassan Seraji has built Cyrus Restaurant (612 Veterans Memorial Blvd., Metairie, 309-2477), which serves the traditional Persian cuisine of his native Iran. The menu includes a range of salads and dips and grilled meat and fish entrees served with rice pilaf. Stewed chicken with cranberry rice is one specialty. Cyrus also has a full bar.
