Wooden wine barrels with taps, shabby old furniture, noisy antiquated fridges, soda siphons from the 1960s… these are the building blocks of Barcelona’s classic bodegas. Formerly shops that sold bulk wine, liquor and ice, these bodegas survived the Spanish Civil War, social conflicts, food shortages, financial crises and, of course, modernity, with their essence intact, even if they morphed into bars or restaurants along the way. The most important element of a neighborhood bodega, however, is neither readily visible nor easily captured: it’s the place of importance these spots occupy in the lives and hearts of the local residents. They are the scene of innumerable childhood memories and infinite moments shared with other locals from the block, making them a dependable point of reference in time and space.

Carla Santos is a busy woman. On the day we go to meet her, it is pouring rain in Porto and Adega Vila Meã, the restaurant she runs, is full. Carla doesn’t stop for a second: “One of those pork firecrackers with potatoes?” she asks a customer as she swings through the dining room. She’s not alone in this mad dash. Carla works the tables with her youngest daughter, while the oldest, who learned how to cook from her mother, mans the kitchen. Even Carla’s 7-year-old granddaughter helps out, clearing tables. “It costs nothing to start learning right now,” says grandma Carla, already certain that “we are moving Adega from one generation to the next.”

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.

It wasn’t so long ago that no one would venture to Georgia’s Svaneti region without a personal invitation, and even that was risky. Isolated, sky-high in the Caucasus, nestled between the breakaway territory of Abkhazia and the Russian Federation, it was land of the lost, inhabited by a tribe speaking their own language, living in hamlets dominated by tall medieval stone towers used for protection from invading hordes as well as from each other. Ancient pagan-Christian rituals, bride-napping, blood vendettas and banditry defined modern Svaneti – at least when viewed from the outside. We had heard too many stories of how oblivious tourists would wander there with cameras around their necks and big tourist grins only to return in their underwear with their heads hanging low. Like Georgians from the rest of the country, we stayed away.

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 typical Neapolitan breakfast is fast, often consumed standing at the espresso bar. A croissant and a quick coffee – and, boom, the day begins. Many people in the English-speaking world, however, will use coffee bars and cafès as a place to relax or work. They bring computers, connect to the Wi-Fi and, ordering just one coffee, may even sit for hours. Three years ago, a group of entrepreneurs decided it was time Naples had a bar where people could indulge in a lazy morning breakfast, a slow midday meal or a long afternoon tea – a place where the chairs are comfortable, the tables are an inviting wood and you are encouraged to stay and make your phone calls, write your papers and chat with friends.

A neighborhood on the southeast side of Filopappou Hill, between Acropolis, Petralona, Kallithea and Neos Kosmos, Koukaki was named after one of its first residents, Georgios Koukakis, who in the early 20th century opened a successful factory there manufacturing iron beds. Gradually the area developed into a charming middle-class neighborhood, full of life and – up until the 1980s – a place Athenians charmingly referred to as “Little Paris,” in large part because of its bohemian vibe. The lower side of Koukaki has long been a students’ area due to the nearby Panteion University. Rents used to be relatively low, but after the opening of the new Acropolis Museum in 2009, the surrounding area has been booming, growing into an Airbnb goldmine and turning many locals against the trend.

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).

Ask any former resident of the Balkans now living in New York where they buy the flaky, savory phyllo pie known as burek, and they may very well direct you to Djerdan Burek in Astoria. Burek (also known as börek) is a staple eaten in many forms throughout the regions that once formed the Ottoman Empire. In New York City, though, most purveyors of burek come from Albania and Bosnia, and if you’ve ever ordered a slice of burek at one of the many Albanian-run pizzerias in the Tri-State area, there’s a good chance it was baked by Djerdan as well. Their Queens storefront is a homey sit-down eatery doling out plates of meaty stuffed cabbage and grilled Balkan sausages, but Djerdan is especially well-known among immigrants from former Yugoslavia for being the only Balkan burek factory in the United States.

Growing up in Athens in the 1980s and 90s, weekend family excursions to a suburban taverna were an integral part of life. Back then, prices were affordable and eating out was not a luxury; in fact, it was a social necessity. It was a way to catch up with friends, enjoy good food and good wine, but also to entertain the kids. These tavernas were often away from the city center, in areas that offered a break from the gray buildings and the heat – usually with a large outdoor area shaded by trees, encompassing a playground and sometimes even a pond with small boats to enterain the kids. The food on offer was basic, but delicious – mainly meat (grilled lamb chops, etc.), salads, fried vegetables (zucchini, eggplant, potatoes) and dips (tzatziki and tyrokafteri, a spicy feta spread).

Despite being one of the liveliest of Lisbon’s neighborhoods, Alvalade doesn’t appear in most city guides. Maybe because of the location, north of downtown and next to the airport, with planes taking off and landing being part of the usual sights and sounds. Maybe because it is mainly a residential area, with few – if any – hotels available nearby. Maybe because it is seen as a strictly local neighborhood, with no museums, elevated viewpoints or places to listen to fado. But despite all that, it has a lot to offer, especially to those who want to eat, shop or simply roam the streets with the locals. Let’s focus on that first verb: to eat. In Alvalade, there are still plenty of places that offer traditional Portuguese food at traditional Portuguese prices: less than 15 euro per meal. Some of the neighborhood’s best tascas have been recently renovated, with a slight increase on the bill – nothing too hefty – but keeping the same old-style cuisine and the daily dishes that have been attracting a faithful clientele for the last few decades.

Like many other Egyptians, when Cairo Restaurant owner Magdy Hegad talks about khushari, his eyes glisten with an emotion akin to love – but when he talks about seafood, the glisten is elevated to something closer to religious fervor. “We do it differently,” he explains. “Just try it, and you will see.” We first ventured to Cairo Restaurant with an Egyptian friend eager to show us the delights of a cuisine we had learned little about, let alone tried. As we entered the restaurant, it became clear that this was to be a very different meal than what we had grown used to in dining around the city.

As women in pink polo shirts conveyed steaming tureens, pungent earthenware crocks and freshly-baked sweet loaves, it was clear that the Azores’ celebration of the heavenly spirit had a strong component of earthy sustenance. We were at a função (function), a communal meal built around bread, wine and traditional meat dishes that forms a central part of the archipelago’s unique Holy Ghost festivities, which take place in villages around the islands over the 50 days after Easter. “This is one of the island’s most deeply respected traditions and it’s taken very seriously,” explains José Álamo Meneses, mayor of Angra do Heroísmo, a jaw-droppingly beautiful UNESCO World Heritage city on the island of Terceira. “Only around 10 percent here go to mass regularly, but they fill the churches on the day of the Holy Spirit,” he adds, before joining 250 fellow citizens for lunch in a hall hung with patchwork blankets in the hillside neighborhood of Bicas de Cabo Verde.

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.

The up-and-coming, terroir-obsessed wine distributor Os Goliardos is reached through a tiny alley that opens into a courtyard behind an apartment block in Campolide, a residential Lisbon neighborhood just north of the Amoreiras shopping mall. The company keeps a low profile, hiding Lisbon’s greatest wine storeroom in a narrow garage that counts several auto body shops as its neighbors. Since they keep odd hours, we were told to find a mechanic named Senhor Rui who would let us in with his key to pick up our order. We looked for him in a dark garage, where a man sat, listening to fado on the radio, beside a distressed Fiat. Wrong mechanic. Suddenly a large, smiling man in work clothes appeared in the yard jangling a set of keys.
