Chain restaurants are dining establishments that operate under the same brand and offer similar menus across multiple locations. They are often part of a larger corporation and maintain standardized practices to ensure consistency in food quality and service. Popular examples include McDonald's, Starbucks, and Olive Garden. These restaurants benefit from economies of scale, allowing them to purchase ingredients in bulk and reduce costs. They often have recognizable logos and marketing strategies, making them familiar to customers. Chain restaurants can be found in many cities and are popular for their convenience and predictability in dining experiences.
