Fast food has come a long way from simple roadside diners to the massive global industry it is today. It started in the early 1900s with quick-service restaurants like White Castle, which introduced the concept of standardized meals. Then came McDonald’s in the 1950s, revolutionizing the industry with its assembly-line model. Over time, menus expanded beyond burgers and fries, adding healthier options, international flavors, and even plant-based alternatives. Today, fast food is all about speed, convenience, and innovation, with mobile ordering, AI-driven kitchens, and sustainability efforts shaping the future. 🚀🍔
