Fast food refers to a type of food that is prepared and served quickly, often at restaurants that specialize in speed and convenience. These establishments typically offer a limited menu of items that can be made rapidly, such as burgers, fries, and pizzas. The appeal of fast food lies in its affordability and accessibility, making it a popular choice for people on the go. In addition to traditional fast food chains like McDonald's and Burger King, the industry has seen a rise in healthier options and gourmet fast food. Many consumers are now seeking alternatives that offer fresher ingredients and more diverse flavors, reflecting changing dietary preferences and lifestyles.
