Definitely check out Sizar's for Greek and Middle Eastern items like yogurt, breads, spices, and olives. Currently, there is a Ramadan special on dates -- $6 a pound for regular and $8 a pound for spectacular jumbo ones. They're better than candy. But if you have to buy candy (and I do), try the pistachio nougat at the high end ($9 for 12 ounces) or the Turkish Coco Star candy bar at the low (39 cents for a bite-sized bar at the check-out).
