Historians believe the first modern restaurant was opened in 1765

A Parisian soup salesman named Boulanger is often credited with opening the first modern restaurant and was renowned for serving meat in poulette sauce.

The Mister Softee ice cream truck began with two brothers in a Chevy van in Philadelphia, selling green ice cream.

Ice cream can be traced back to a frozen milk dish from the 7th century.

There's no definitive proof that Boulanger, the supposed inventor of the restaurant, ever lived

Legend has it that Boulanger's Paris soup shop was the first modern restaurant, but historian Rebecca Spang found no definitive proof that he ever lived. She did, however, find multiple documents referencing a different 18th-century Parisian, Mathurin Roze de Chantoiseau, as the "creator" of restaurants. (Some readers may experience a paywall.)

George Washington loved to serve ice cream while hosting guests, and spent thousands of dollars on it in a single summer.

One baker is likely responsible for several of New York's earliest pizzerias

Filippo Milone established at least six pizzerias in New York, including one that would later be called Lombardi's, widely considered to be the city's (and the country's) first pizza establishment. Milone died in 1924, leaving no children to tell his story. Researcher Peter Regas unearthed a 1903 advertisement, pictured below, from an Italian-language New York newspaper.

In the 19th century, ice-cream-related illnesses were somewhat regular in America thanks to vendors' poor hygienic practices.

Ice cream, gelato, sorbet, and Italian ice are all popular cold desserts, though they have many important differences.

America's ice cream obsession began under Prohibition, with the street treat acting as a legal vice that helped ease the pain of the Great Depression.

Agnes Marshall invented 'ices,' the Victorian equivalent of ice cream, and improved the period's hygienic practices for consuming the dessert.

Kulfi, an ice cream predecessor that's still popular in South Asia, dates back to the 16th century.

The frozen pizza was invented in 1950

In 1950, some pizzerias were premaking pies, allowing customers to take them home and cook them at their convenience. That same year, Philadelphia's Joseph Bucci filed a patent for a "Method of Making Frozen Pizza." Soon, frozen pizzas were appearing in grocery store aisles.

Delmonico's was the first American fine-dining restaurant

The steakhouse opened in 1837 in Manhattan, creating what is now considered the first fine-dining restaurant in the United States, introducing gloved waiters, white tablecloths, and an à la carte menu. The establishment also claims it invented a few American staples, including eggs Benedict, which was supposedly named after two loyal customers.

Lombardi's was the first documented pizza restaurant in the US

The New York establishment opened in the early 1900s and was a cornerstone of Manhattan's SoHo. At one point, it was open 23 hours a day, allowing laborers of the predominantly Italian-American community to stop by for pies before or after work.

France's first restaurant guide, 'Almanach des Gourmands,' helped spread the restaurant concept across Europe and the US.

The first coffeehouse opened in Constantinople

Coffeehouses began opening in modern-day Istanbul sometime in the 1500s. These cafes quickly became invaluable spaces for gathering and exchanging news and ideas.

The frozen margarita was invented in Dallas using a repurposed soft-serve machine

On May 11, 1971, Dallas restaurateur Mariano Martinez adapted an ice cream machine to produce frozen margaritas using his father's recipe. The original machine now sits in the Smithsonian's National Museum of American History.

Vanilla was originally used as an additive in chocolate rather than as a standalone flavor.

The fast food shops of ancient Pompeii

Researchers have unearthed a frescoed thermopolium (a sort of hot food and drink shop) in Pompeii, the ancient Roman city frozen in time after the catastrophic eruption of Mount Vesuvius in 79 CE. This fascinating discovery provides a glimpse into Roman culinary practices and the daily life of Pompeii's citizens.

Coffee brewing likely originated in Ethiopa and the Arabian Peninsula

A mixture of merchants and colonialism then launched the drink across Europe and the New World. Many European coffee traditions, like the Viennese custom of serving it alongside a small cup of water, are remnants of how coffee has been prepared in the Middle East for centuries.

The word 'restaurant' comes from the Latin for 'restore'

Many believe the word came into use thanks to Boulanger, an 18th-century Parisian soup vendor. According to legend, his shop claimed it served "bouillons restaurants," or "restorative broths."

Pizza is believed to have been invented in Naples

Flatbreads were eaten by ancient Egyptians, Romans, and Greeks, but historians trace pizza—flatbread with toppings, including present-day staples like tomatoes, cheese, garlic, oregano, and oil—back to 18th-century Naples, where the food was loved by its working poor, who appreciated a cheap, tasty meal. Naples formally became a part of Italy in 1861.

There's no definitive reason why an ice cream sundae is spelled with an 'e' rather than a 'y.'

One food history professor says pizza is more American than Italian

Alberto Grandi, a professor at the University of Parma, argues that Italians who left the country developed the food now considered "traditional Italian cuisine," thanks to abundant ingredients and opportunities that were not available in the impoverished country they left behind.

The steak sandwich had been around since at least the 1800s, but in the early 1900s, a Philadelphia hot dog vendor topped it with cheese and used different bread to create the cheesesteak.

Chicago deep-dish pizza arrived in 1943

Pizzeria Uno was the first establishment to sell the concoction, which turned more traditional pizza upside down, with cheese as the base and sauce as the topping. Soon, Uno employees went out on their own, sparking a citywide deep-dish phenomenon.

Ancient Romans helped develop modern cheese production techniques

The ancient Romans loved cheese and experimented with different processes to elevate its flavor, like aging. Some of their innovations, like Pecorino Romano, you can still find today. Others, like the smoked goat-milk Caseus, we only know about through historical records.

A fresco from ancient Pompeii featured an 'ancestor of modern pizza'

A team of archaeologists discovered a fresco from 79 CE featuring what appears to be a proto-pizza: a pita topped with fruit, spices, and other toppings. One archaeologist in the PBS documentary below calls it an "ancestor of modern pizza in the sense that it's a very simple, poor kind of food."

Italian immigrants brought pizza to Argentina in the late 19th century

Two million Italians emigrated to Argentina between 1880 and 1920, many of them the poor who regularly ate pizza. In Argentina, they were pleased to find that mozzarella was plentiful, allowing them to make cheesier pies. By 1882, Italians owned 126 of the 198 bakeries in Buenos Aires, as well as the majority of shops selling butter, cheese, and pasta.

Ice cream trucks are surging in popularity

Modern companies like HipPOPs and Big Gay Ice Cream are driving a resurgence of ice cream trucks, with an annual growth of approximately 9%. Experts say the market will keep growing through at least 2030.

Ancient Rome had an early version of macaroni and cheese

Called placenta (with a hard "c"), the holiday dish consisted of sheets of rolled-out dough layered with cheese. It is the first recipe documenting the combination of the two elements. While there is debate about whether the dough can be called pasta because it's not boiled, many scholars view the dish as a proto-lasagna.

Pizza didn't take off in the US until after World War II, likely because of technological advancements and soldiers' exposure to it abroad.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

The first glasshouse was constructed in 1931

The Maison de Verre in Paris was built to house a doctor's office on the ground level and an apartment upstairs. Unlike the typical model that would follow, this glass house exposed very little of the home's interior.

Pizza became more popular in Italy after it took off in the US

Pizza was invented in Naples, though it wasn't particularly popular outside the region. As it grew more popular elsewhere—and as more American and European tourists visiting Italy began asking for it—restaurants across Italy adopted the cuisine. It's something anthropologist Agehananda Bharati calls "the pizza effect."

Ice cream’s unfrozen consistency is thanks to sugar

Making ice cream is a complex, multistep scientific process. But the treat’s scoopable, chewable consistency is due to the product’s dissolved sugar.

The American diner evolved from a 'lunch wagon' into a restaurant

Providence, Rhode Island's Walter Scott began serving homemade dishes from a freight wagon to late-night workers, who were looking for meals long after proper restaurants had closed for the night. Scott quickly inspired dozens of copycats, crowding the streets and leading to complaints. Soon, Scott and his imitators parked their carts, which became the earliest American diners.

Art Deco formally began in France in 1925

The design style—often associated with 1920s New York—is named after the International Exhibition of Modern Decorative and Industrial Arts in Paris, which featured many works in the style, which was already popular in France.
