There are many restaurants in Detroit which serve the foods of these areas. There are many other international restaurants too. Americans enjoy the foods in these restaurants as well as the opportunity to better understand the people and their way of life (31) . one of the most common international restaurants to be found in the United States is the Italian restaurant. The restaurant may be a small business run by a single family. The mother of the family cooks all of the dishes, and the father and children serve the people who come to eat there (32) . or it may be a large restaurant owned by several different people who work together in the business. Many Italian dishes that Americans enjoy are made with meats, tomatoes and cheese, they are very delicious and tasty. (31)
