I don’t think there is an authentic American fast food restaurant in Shanghai. It is a real American size burger, a real American burger, a solid fire roast beef, authentic, ready-made, cola, soda is not afraid of people, this is the characteristics of the card. Carrefour is a chain of fast food restaurants from California, and its branches can be seen near the highways in several major cities in the West Bank. In 2009, the company opened four branches in Shanghai. Because of the authentic taste, so many Americans working in Shanghai come here to relish their hometown flavor, which proves that their taste is really loyal to the original taste.
