Ancient Romans Invented Fast Food Over 2000 Years Ago

The thermopolium was a place of refreshment in ancient Rome, a sort of snack bar where drinks and hot food were served. While the Greeks might dispute this claim, the first archeological evidence of a fast-food establishment dates back to ancient Roman times, more than 2,000 years ago. Lacking kitchens in their multi-story apartments, a growing population of city dwellers would buy prepared food from food counters called “thermopoleums”.
Several thermopolias have been found in Pompeii, where there are 89 of them, in Herculaneum and ancient Ostia. Perfectly preserved food kiosks have been unearthed from the ash of ancient Pompeii, complete with signage indicating a menu that included duck, goat, and snails. A mere 40 percent of the lower-class homes and 66 percent of middle-class ones in the Vesuvian area had a hearth with which to cook, meaning the average working-class citizens relied on these establishments for sustenance.
Medieval Paris Had Thriving Street Food Networks by the 12th Century

Paris was one of the most vibrant street food capitals of medieval Europe. By the twelfth century, the city had developed a thriving network of food vendors who set up stalls along major thoroughfares and bridges. Historical records indicate that Parisian street vendors sold grilled meats, soups, and various types of bread.
The French historian Jean-Louis Flandrin notes that in medieval Paris, it was common for vendors to sell “waffles, pancakes, and tarts to passersby, often directly outside churches or busy marketplaces.” The city’s street food culture was so integral to daily life that municipal authorities established strict regulations to maintain food safety and prevent fraud. London’s medieval street food scene was similarly bustling. By the thirteenth century, the city’s streets were filled with vendors selling everything from roasted meats and fish to hot pies and fried dough.
Thomas Jefferson Introduced French Fries to America in 1802

In 1802, Jefferson had “potatoes served in the French manner” at the White House and subsequently introduced French fries to America. This presidential endorsement helped establish what would eventually become one of fast food’s most popular items. Now, it’s the second most popular fast food item.
The timing was perfect for America’s growing love affair with convenient foods. Jefferson’s influence as a founding father meant that French fries gained immediate social acceptance among the upper classes. This early adoption would prove crucial when fast-food chains began standardizing their menus more than a century later.
Automats Were the Real Predecessors to Modern Fast Food

Automats, vending machine restaurants, were invented by Max Sielaff in Berlin in 1895. Introduced in Berlin, Germany, in 1895, this new form of casual dining made its way to Philadelphia in 1902 courtesy of restaurateurs Joe Horn and Frank Hardart. Essentially a self-service cafeteria, the automat featured rows of windowed compartments along its walls, from which hungry customers could retrieve an array of prepared dishes by depositing a coin.
Horn & Hardart, a famous chain of automats, started in Philadelphia in 1902 and expanded to New York City in 1912. Though automats didn’t have classic fast food, they introduced customers to the concept of getting their food right away and serving themselves. These mechanical marvels trained an entire generation to expect immediate food service without human interaction. Automats were popular for years until a new kind of fast food took over the convenience food industry.
White Castle Overcame America’s Fear of Ground Beef

Yet in the early 20th century, many people were reluctant to eat burgers. Consumers suspected ground meat was low quality, thanks in part to the gruesome depictions of the meatpacking industry that Upton Sinclair had created in The Jungle (1906). Although Americans were leery of ground beef following the exposé of the meatpacking industry that featured in Upton Sinclair’s 1906 novel The Jungle, Anderson eased those concerns by preparing his food in public view.
Co-founder Walt Anderson had already developed a method to quickly cook delicious sliders, and to make people more comfortable with the idea of eating burgers, White Castle emphasized the cleanliness of their restaurants. White Castle’s founders decided to change the public’s perception of hamburgers. They built their restaurants so that customers could see the food being prepared. They painted the buildings white and even chose a name that suggested cleanliness. Even so, in 1961, White Castle became the first restaurant chain to sell 1 billion burgers.
McDonald’s Borrowed Henry Ford’s Assembly Line for Food Production

The foundation for McDonald’s success was laid in 1948 when Richard and Maurice McDonald restructured their small San Bernardino, California, restaurant into an assembly-line operation. Inspired by the efficiency of factory production, they introduced what they called the “Speedee Service System,” a revolutionary approach that streamlined food preparation by eliminating unnecessary menu items and focusing on a few core products – hamburgers, fries, and milkshakes.
In later memoirs, the brothers would credit Henry Ford as the inspiration for their process, saying that they modeled their restaurant around his assembly lines in Detroit. Their streamlined production method, which they named the “Speedee Service System” was influenced by the production line innovations of Henry Ford. They had a radical idea — the Speedee Service System: limited menu, walk-up service, assembly-line food production, and drastically reduced prices. At the end of 1948 they introduced this new system, which revolutionized the fast food industry.
The Drive-Through Was Invented to Serve Lazy Car Owners

In 1921, Jesse G. Kirby and Rueben W. Jackson opened the Pig Stand in Dallas, TX, America’s first drive-in, and changes fast food forever. Kirby has been quoted saying, “People with cars are so lazy,” Kirby explained, “they don’t want to get out of them.” This brutally honest assessment proved prophetic about American car culture.
Much like the debate over the birthplace of hockey in Canada, there are competing claims for the title of the first drive-through. Many say the distinction belongs to Red’s Giant Hamburg in Springfield Missouri in 1947. In-N-Out Burger revolutionized the concept of a drive-through in 1948 when it allowed customers to order from their car using an intercom system. These innovations recognized that Americans were becoming increasingly attached to their automobiles and didn’t want to interrupt their driving experience for a meal.
KFC’s Secret Recipe Contains Exactly 11 Herbs and Spices

In 1940, Harland Sanders finalized his Original Recipe of 11 spices and herbs. The recipe is STILL a well-guarded secret. KFC’s 11 secret herbs and spices give their fried chicken its signature flavor, and the company’s homestyle sides are also quite well-known.
This carefully guarded formula became one of the most famous trade secrets in food history. During this time, Kentucky Fried Chicken (KFC) also began franchising on a large scale, with Colonel Harland Sanders promoting his “Original Recipe” of seasoned fried chicken across the country. The mystique surrounding the recipe has generated countless attempts to reverse-engineer the formula, making it one of the most discussed secrets in the culinary world. Sanders reportedly kept the recipe in a safe and only a handful of people have ever known the complete formula.
White Castle Burgers Have Five Holes for a Scientific Reason

White Castle meat patties are square shape and have five holes in them so they can be cooked without turning over. This ingenious design solved a fundamental problem in fast food production. The holes allowed steam to escape and heat to penetrate evenly, ensuring consistent cooking throughout the patty.
This innovation was pure engineering brilliance disguised as simple food preparation. The five-hole pattern became White Castle’s signature feature, instantly recognizable to customers and completely functional for kitchen efficiency. The square shape also maximized the number of patties that could fit on a grill, another example of how early fast-food pioneers optimized every aspect of production. Locals quickly took to the compact 5-cent burgers, later known as “sliders,” and Anderson soon opened two more stands.
Subway Built a Mobile Restaurant Inside the World Trade Center

According to some accounts, Subway reportedly operated a mobile restaurant during World Trade Center construction, though this story remains unverified by historical documentation. If true, such an innovation would have demonstrated the lengths to which fast-food chains would go to serve customers in unusual circumstances, adapting their business model to serve customers wherever they gathered.
# Conclusion
