The Neapolitan stairs are ancient urban routes that connect the upper city (the Vomero district) to the lower city (the historic center). The most famous of these stairs is the Pedamentina di San Martino, a staircase of 414 steps dating back to the 14th century, which starts from the old center and reaches the Castel Sant’Elmo, on the Vomero hill. Along the way there are beautiful panoramic views of Naples. One reason to walk these Neapolitan stairs (besides the views) is to look for Totò Eduardo E Pasta E Fagioli, an old tavern with an amazing terrace overlooking historic Naples. The name is dedicated to two great masters of Neapolitan theater and cinema: Totò (Antonio de Curtis) and Eduardo de Filippo.

If a gastronomia or delicatessen prepares good food, it can survive for decades. But if a gastronomia also promotes a social cause, there is a risk that clients will visit once to silence their consciences, and not return. At Sfizzicariello, a “social gastronomia,” the food is at once excellent, and the cause worthy. A group of 10 people with mental health disorders run the deli, an example of commitment but, above all, quality dishes that will keep people coming back. Here is one of the best eggplant Parmigiane in Naples, an exceptional endive pizza, and a number of unparalleled meatballs. Come for a quick snack, a long lunch break sitting at one of the few tables scattered about or to order take away. The environment is modern in design, with eight seats inside and four out.

Come summertime, Carmine, a street vendor for all seasons, prepares refreshing granita on Via dei Tribunali in Naples. The semi-frozen dessert made from sugar, water and various flavorings, counters the oppressive heat. Don’t leave before exchanging a few words with Carmine, who is renowned for his ability to strike up a conversation with anyone.

We are in the Vasto district, a difficult to navigate maze of narrow streets that criss and cross, a market area squashed between Naples’ central station and Centro Direzionale, the business district. The district’s Via Nazionale, a street adjacent to the station, is a shrine to local gastronomic treasures, and we consider it a true paradise for lovers of good food. It’s a jewelry box of flavors, ideas, and unique and original products. The daily street market on Via Ferrara, another local artery, is one of the city’s most colorful and fascinating – mentioned several times in renowned author Elena Ferrante’s “My Brilliant Rriend.” It was here, in 2016, that Dario Troise brought to life a project 15 years, if not centuries, in the making: a panini bar that serves only cuzzetiello (which roughly translates to bread bowl sandwiches).

When the other butcher shops in Naples are closing for lunch and at the end of the day, activity at D'Ausilio Macelleria is just picking up. The cooktops are lit, sandwiches are being made and this Italian butcher shop becomes a quality burgeria. “I come from Vomero (the hill district) to buy Raffaele’s hamburgers. My children love them,” says customer Rosaria Esposito at 8 p.m., when the macelleria is an hour into its transformation as a burgeria. But this is no trendy burger bar; the menu is steeped in local heritage. Rosaria leaves the burgers to the kids, choosing for herself the delicious home-style dishes created at D’Ausilio. Parmigiana alla Genovese stands out among those on display. Here are two sacred words of Neapolitan cuisine – Parmigiana and Genovese, a simple yet miraculous sauce made of meat (veal, beef or pork) and a heap of onions (red or white) – cornerstones in the history of local cooking.

An espresso coffee is an integral part of most Neapolitans’ morning routine. We start off our walk with a (small) cup of this potent brew and sfogliatella, a pastry first created in a Catholic convent near Naples.

At any time of day you’ll see crowds of people at the ancient, welcoming restaurant. At lunchtime, many regulars come daily not for the pizza, but for Maria’s home cooked dishes. “Here we serve traditional Neapolitan dishes,” says the 74-year-old. “Pasta and potatoes, pasta and beans, pasta sorrentine style or bolognese. The menu changes every day, and the bread is made every morning, here, directly in the pizza oven … with my hands.” There’s something about the pizzeria that transmits a sense of history, particularly its inner room, the walls of which are covered in declarations of love for the restaurant and drawings made on paper napkins by loyal customers over the decades. “It is as if customers wanted to leave something of themselves,” Attilio tells us proudly. “They wanted to return some of the goodness they just tasted with something that would last.”

Being a street butcher in Naples is not for the faint of heart. “Rain, sun, wind, heat, cold… being on the street seven days a week means knowing how to face every type of weather,” says Gaetano Iavarone. He is part of the invincible team behind Macelleria Iavarone, a butcher shop in Naples’ Sant’Antonio Market run by Domenico (Mimmo) and his three sons, Gaetano, Lorenzo and Davide. The so-called “street butcher shop” has a huge display of meat outside with only a small cash register inside. Also inside is a larger photo of Gaetano the elder, Domenico’s father, who opened the butcher shop 60 years ago. Domenico took over the reins 30 years ago and now runs it with his close-knit team of sons.

Pizzeria Gino Sorbillo has been serving pizza made with bio flour, which is made from grains that haven’t been exposed to fertilizers or other pesticides, and mother yeast, the proportions of which are top secret, since 1935.

Sold for one or two euros, the spritz, which at its most basic is a combination of bittersweet liqueur, sparkling wine and seltzer, has been dubbed “the champagne of the poor” – no wonder it has been the king of cocktails in Naples for at least a decade. Aperitif time – often starring a cool spritz – is the most relaxing, and thus most awaited, moment of the day. And Neapolitans have made an art of this pre-meal ritual. In a city that is known (although sometimes unjustly) throughout Italy as the city of the idle, the aperitif has come to symbolize living well, in the company of friends.

Like the Proustian madeleine, sweets can stir up all kinds of feelings in the minds of those who eat them. In Naples, struffoli (small, round doughnuts glazed with honey) and cassata (sponge cake with ricotta and candied fruit) speak of Christmas, while chiacchiere (sugar-dusted fritters) and sanguinaccio (literally “blood pudding,” but actually made of chocolate) bring to mind Carnevale. And then there’s pastiera, whose very scent and taste make us think of Easter and spring. These days, pastiera can be made all year long, not only when the wheat has just sprouted, as was the case for our ancestors. Yet, when Easter approaches, all Neapolitans dream of this tart.

The handywork of Pasquale De Stefano, better known as Pasquale ‘o nummararo, “the number man,” can be seen all over Naples. His signs, which he hand paints on wooden boards with ancient paintbrushes, are used by food businesses and fruit and vegetable vendors across the city. On our Naples walk, we visit his workshop to chat with the master himself.

Some people might tell you that the patron saint of Naples is San Gennaro, a 3rd-century bishop who died as a martyr. But that’s not actually true. The patron saint of Naples is, in fact, Diego Maradona, the Argentinian-born soccer player who, in 1987, propelled Napoli to win the Serie A Championship (Italy’s top football league) – it was the first team ever from the impoverished Italian south to do so. To this day, Maradona’s portrait is everywhere in the city. Just like any good patron saint, his picture watches over shopkeepers, restaurant owners and families in their living room. So when someone on the street called Francesco Sepe the “Maradona of wine,” you can imagine how proud he felt.

Rua Catalana is a very ancient road, a corner of Naples where time seems to stand still. Located next to the financial district and now squeezed by 19th-century buildings, it is curiously the only road in the city that, instead of the Italian “Via,” uses “Rua,” a distortion of the French “Rue.” In the mid-14th century, Queen Joanna I of Naples welcomed merchants from all over Europe to the city as part of her efforts to promote trade. She donated this area to the Catalans, and tinsmiths and junk dealers settled here. Even though 700 years have passed, a smattering of small copper and tin artisans continue to practice their craft on this street, now making artistic copper and tin objects for the increasing number of tourists roaming the city.

It almost never snows in Naples. Yet in the last decade, the city has seen an invasion of snowflakes. We’re not talking about an atmospheric phenomenon – rather, it is Pasticerria Poppella’s il fiocco di neve (“the snowflake”), a true gastronomic prodigy that has quickly become a “new classic” of Neapolitan pastry, as evidenced by the long lines at the bakery every day of the week. Ciro Poppella is quite a character: not only an important figure in the Sanità neighborhood, where Poppella is located, he’s also an icon of Naples. The inventor of the snowflake, Ciro is a living example of how there are no limits to what you can achieve when you believe in a project.
