A restaurant chain is a group of restaurants that are connected through ownership, management or branding. These chains can be found in various parts of the world and offer different types of cuisine, from fast food to fine dining. They often have standardized menus, prices, and procedures to ensure consistency across all locations. Many restaurant chains operate on a franchise model where individual owners purchase the rights to use the chain's name and operational systems in exchange for fees and royalties. Some well-known examples of restaurant chains include McDonald’s, Burger King, KFC, Starbucks, Subway, Taco Bell, Pizza Hut, Dairy Queen, and many more.
