Faten Saad knew she wasn't in a typical Wal-Mart when she saw an end-of-the-aisle display featuring Mamool. Boxes of the date-filled, whole wheat cookie from the Middle East welcomed the 21-year-old Lebanon native into the international aisle of the new Wal-Mart store in this Detroit suburb known as the capital of Arab America. Aisle 3, which also features Eastern European and Hispanic food, represents many of the 550 items geared toward Arab-American shoppers in the store that opened last week.
