The typical Neapolitan trattoria is a place where you go to eat like you would at home: the cook buys everything fresh in the morning, just like at home, and then spends the rest of the day in the kitchen, which he rules like a maestro. For the quintessential trattoria experience, we head to Fuorigrotta, a working-class district on the west side of Naples. There, close to the border with the seaside suburb of Bagnoli and not far from the Cavalleggeri Aosta metro stop, stands Cucina da Vittorio, a small trattoria with a few tables and a steady rotation of regular customers.

A visit to Varsos, a culinary landmark in Athens that looks much the same as it did 60 years ago, is like traveling back in time to one of the city’s grand patisseries of the 1950s. The venue, which is still in the hands of the Varsos family who originally opened it, is one of the most famous of Athens’ old-style coffeehouses and is the only one that has kept its traditional charm over the last several decades. Varsos was established in 1892 in central Athens, but it is the wonderfully old-fashioned Kifisia location, to which the patisserie moved in 1932, that has made the venue famous. At the beginning of the 20th century, Kifisia was a holiday destination for rich Athenians, and their stately summer mansions still dot this beautiful yet ever-expanding northern suburb, which is now popular with professionals, families and expats.

Zé Paulo Rocha was born in September, 22 years ago. By December of that year, he was already sleeping on top of a chest freezer in his parents’ tasca, right behind Rossio, one of Lisbon’s main squares. Like so many tasca owners in the Portuguese capital, they had come to Lisbon from northern Portugal’s Minho region years before. As a young teenager, Zé Paulo used to help with the service while his mother cooked and his father ran the business behind the counter, the traditional family tasca format. His professional fate was sealed from the beginning.

Kadıköy’s Kimyon is a friend of the after-hours and the booze-fueled denizens who are done at the bar but have yet to call it a night. It is the buffer zone between too many drinks and a brutal hangover, and doesn’t judge those who are still up at 6:30 a.m., because it’s still open and orders of grilled chicken skewers are freshly sizzling above the charcoal. Kimyon runs nearly around the clock, save for perhaps an hour at dawn when operations shut down for cleaning. Appropriately, it’s located in the dead center of Kadife Sokak (Velvet Street), whose elegant name belies the revelry that takes place inside and frequently spills out of the numerous drinking establishments that give the street its de-facto moniker: Barlar Sokağı (Bars Street).

In early September and October, Athens – just like many other cities around the world – sees an influx of young people leaving home for the first time to spend the next four years in intellectual pursuits and drinking coffee. Few among them are as concerned with what they’re eating as they are with other, seemingly more important matters, and so Greek student life is usually associated with deliveries of souvlaki, pizza and other minor domestic disasters. But for young people eating on the cheap, fast food doesn’t have to be the only option; local restaurants often offer student specials this time of year.

There’s a beautiful Greek island on the eastern edge of the Aegean Sea that is officially called Chios, but is unofficially known as “Mastiha Island.” The fifth largest among Greek islands, Chios is blessed with fertile land and a celebrated microclimate that allows islanders to grow a unique range of products, the most famous being – as its nickname suggests – mastiha (mastic), an aromatic resin produced by mastic trees. The first references to mastiha on Chios can be found in the work of Herodotus, the ancient Greek historian, who, in the 5th century BC, described those trees that grew on the south side of the island and how the ancient Greeks collected their resin and chewed it, both for pleasure and hygienic purposes. In fact, mastiha has been described as the first chewing gum in history.

It was a scorching summer day in Istanbul, one of those days when the only thing you can imagine eating is ice cream. We were in Moda, and our friend Vicente suggested a stop at Dondurmacı Yaşar Usta – in fact, he’d been raving about this ice cream all summer long. So we followed him to the branch on Bahariye Caddesi, in hopes of understanding why he’s so crazy about it. It didn’t take long for us to figure things out. The homey, no-frills atmosphere and the array of creative ice cream flavors make Dondurmacı Yaşar Usta something of an oasis in Moda, a hip neighborhood on Istanbul’s Asian side, where a majority of the new food ventures springing up like mushrooms prioritize a shiny cool look over substance.

Tucked against the back wall of the Expendio de Maiz kitchen are three massive metal pots. Containing cloudy mixtures of corn kernels and limestone water, they seem to sit unattended, when in fact intermittent yet constant attention is being paid to their progress. What is happening is one of the most ancient and important processes birthed by Mesoamerica: nixtamalización. For a people whose main staple was corn, the discovery of nixtamalization was just as important as the domestication of corn itself. This process of mixing corn kernels in an alkaline solution not only loosens the husks of the corn kernels, making them easier to grind, but also provides all kinds of additional nutritional value.

One of the problems for travelers with celiac disease is that they often can’t taste local gastronomic specialties. This is particularly true in Naples, a city famed for its pizza and pastries, such as the mythical babà; pastiera, the queen of Neapolitan sweets; and the ancient sfogliatella. Until about 20 years ago, it was very difficult for someone with celiac disease to eat in Naples; the number of restaurants equipped for gluten-free cooking could be counted on one hand, and they often had to resort to processed food products sold in pharmacies.

If anything in recent history has bonded Spanish hearts, it was neither politics, language, flags nor even TV. It was the tortilla de patatas, the iconic potato omelet. In every house, bar and restaurant, the tortilla de patates is always treated with intimacy and respect, like some sort of communal great-great-grandmother. And in every Spanish city, you will find a list of the best kitchens offering this specialty. For Barcelona, one neighborhood temple devoted to the omelet is Les Truites, a small family restaurant in Sant Gervasi run by Joan Antoni Miró and his son Marc.

The Algarve, one of the most visited regions in Portugal, also has some of the country’s most distinctive and delicious cooking. Integrating layers of different historical influences, from the Romans to the Moors, along with fishing traditions and countryside rusticity powered by its fertile land, the Algarve has made a deep impression on Portugal. But until Taberna Albricoque came on the scene, the region hadn’t been making much of an impact on Lisbon menus. Bringing the Algarve’s history to the forefront of Lisbon dining was one of the goals of chef Bertílio Gomes in opening his new restaurant. Albricoque, in fact, is the word for apricot in the Algarve, notable because the south has preserved its Arab etymology, as elsewhere in the country damasco is used (instead associating the fruit with the city of Damascus).

A former village annexed to Barcelona in 1897, the city’s Sant Andreu district was a center of industrial development throughout the 20th century, becoming home to a large population of factory workers. Today, it is a quiet residential area that feels caught between its Catalan village roots and industrial past, with buildings being renovated and repurposed, including factories transformed into creative arts complexes and parks, and a former canódromo (dog-racing track) that is now an “innovation center.” It’s not a part of town that’s considered a dining destination, but Sant Andreu’s El Congrés neighborhood now has its own gastronomic unicorn: TocaTeca, which opened in 2012. A unique establishment of its kind in the area – for now, at least – the restaurant is a gourmet endeavor sustained by a couple of professional chefs, Maria Cots and Guillem Carulla.

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.

Agapi Stavrakaki was born in Anogia, a mountain village on the island of Crete famous for producing fine produce and excellent musicians. Decades before she would open Raeti, a delightful restaurant in Athens’ Ambelokoipi neighborhood which pays homage to her island home, a 10-year-old Agapi worked by her grandmother’s side at her family’s vineyard in Anogia, cooking for the workers harvesting grapes and making wine. She and the other women would prepare huge quantities of food in enormous kettles. Despite being cooked in bulk, the food was always traditional, fresh and tasty – Cretans have high standards! Before continuing with Agapi’s story, a few things about Cretan cooking: One of the most legendary of Greece’s regional cuisines, it makes use of all the simple ingredients that are offered by nature with an open hand.

When a streetcar ran down Queens’ Metropolitan Avenue in the first half of the 20th century, soda fountains like Eddie’s Sweet Shop were commonplace in big cities and small towns across America. Today, this hundred-year-old corner gem on Metropolitan in the leafy, Tudor-style enclave of Forest Hills is one of the last of its kind left in the country, and it certainly shows its vintage. On summer afternoons, Eddie’s still fills up with crowds of happy Queens kids, and the diversity of the clientele reminds you that fortunately, it’s not the 1920s anymore. The shop itself, though, is practically unchanged – every piece of equipment behind the counter, from the shiny Frigidaire to the tiny metal cabinet hand-painted with the words “hot fudge,” could be from a museum.
