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.

When Liz Hillbruner moved to Mexico City in 2010 from the United States, she found herself obsessed with tlacoyos, the little football-shaped street eats she saw cooking on griddles around her neighborhood. They were a perfect package of corn dough, wrapped around beans or cheese. As she ate her way through the neighborhood, she simultaneously enrolled in a master course on Mexican cuisine. When it came time to formulate a final project, it seemed only natural to study what was already on her mind. She decided on a map – the Tlacoyografía – a tool for the community and street food-loving transplants to find all the tlacoyo stands in the tlacoyo paradise that is the San Rafael neighborhood.

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).

The restaurant that Inês Mendonça dreamed of can only be described using the Portuguese expression levantar as pedras da calçada – literally, to raise the stones from the sidewalk” –to create something totally new and groundbreaking. When Porto’s now-popular Ruas das Flores was being restored, the din of construction clanging as workers labored to turn it into a pedestrian-only thoroughfare, Inês was seeing miles ahead. It was there that her restaurant would open its doors, she decided, and it would be a place different from all the rest – relaxed and full of curiosities.

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.

Stretched to translucence by a series of acrobatic, table-slapping wrist flips, then stretched just a bit further until it seemingly must tear under its own weight, the palata dough passes from the hands of Myo Lin Thway. In a moment, other hands take over. Perhaps they fill it with minced spiced chicken, for keema palata, or perhaps they fold it instead into an empty square, soon to be the conveyance for masala-red curry. After a brief interlude at the griddle, the flaky flatbread is surrendered to still other, hungrier hands. Myo, in the meantime, has swirled a little oil on his tabletop and patted down another wad of dough, pressing it wider and flatter until it, too, can take to the air.

It wasn’t very long ago that finding a vegan restaurant in Mexico City was like finding a friend on the city’s overcrowded metro during rush hour (read: impossible). In fact, until this decade there were no exclusively vegan eateries in Mexico’s bustling capital. This is not to suggest that vegan options weren’t available, but exploring the city as a vegan could be a tricky business, and veganism was a little-understood concept. So unusual an idea it was, that journalist-cum-chef Mariana Blanco was often called a loser or perdedora by friends who found her animal-free and plant-rich lifestyle to be at odds with what they knew. So when she opened the first vegan restaurant in the city, and indeed the first in Latin America, she called it Los Loosers.

We bit into the khinkali, its handmade dough indelicate and sticky, as we like it. Steam poured out the newly made hole, and we blew lightly before slurping up the rich stock and gobbling the dumpling down, even the puckered knob. The ground pork and beef was packed with fresh cilantro, the juices absorbed into the jacket. It was a perfect khinkali. A home wrecker. This seducer of a dumpling is molded by the knowing hands of Manana Osapashvili, born in Gudamakhari, a mountain village in Pasanauri, the heartland of khinkali. A professional cook for 29 years, Manana has been making khinkali since she was 10 years old. Today, she is running the kitchen at Sioni 13, located at the Tbilisi Theological Seminary in Old Town. It is a part of the city known for its tourists and hookah bars, and the mediocre "traditionnel" Georgian restaurants that cater to them.

Olivos Comida y Vinos is like an independent movie playing at a small cinema on a quiet street in Sants, a neighborhood just outside of Barcelona’s center. It leaves you with the impression of having had an unexpected, intimate connection with something personal and precious. They don’t have customers – they have fans. Decorated with plants and flowers in a comfortable setting of simple, natural materials, Olivos is full of thoughtful details (enough space between tables, no table cloths for green eating) and super-friendly service. The exquisite food follows a sustainable “slow food” philosophy, where products should be local and obtained in both a clean and ethical way, and everything is cooked with a highly professional hand. In Barcelona, where mainstream culinary trends, big hospitality groups and huge investments in interiors and PR are frequently the rule that moves the masses, the independent, honest spirit at Olivos is a treasure.

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.

For a century and a half, the building housing Guixot has taken on many personalities – though one thing has remained the same: It’s always housed some type of bar that also served food. Now a tapas bar celebrated for its sandwiches, brothers, partners and cheery owners Francisco and José Gutiérrez Murillo have been running the iconic eatery in the Raval neighborhood since 1986. Here we can find some of the more interesting sandwiches of the Old City, along with good tapas and a lunch menu of daily specials. Exuding a relaxed, familiar and friendly atmosphere, the space still keeps an old school look with its marble tables and thin iron columns from the past century dotting the interior. It makes good use of its walls, exhibiting paintings that seem to recall its previous life – and it’s had many.

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).

Addy has cornered the Astoria market in Kenyan cuisine. Even so, large portions of his menu are devoted to dishes familiar all around the world, and popular with all ages. They include a dozen or so flavors of chicken wings and a fistful of burgers, some basic, some overloaded. (Lean forward over the plate, is our advice, when biting into a Juicy Lucy.) To our surprise, the American South stakes a claim at Addy's after all: The country-fried steak, served atop mashed potatoes and accompanied by a brimming cup of gravy, is one of the best we've ever had. Because mishkaki is new, at first, to most of Addy's clientele, he's simplified the presentation rather than risk confusing his customers. Typically, at a Kenyan roadside stall, mishkaki is served with flatbread, the meat arrives on the skewer, and the customer adds sauces and other accompaniments to his or her liking. In Astoria, mishkaki is served with rice and a salad, and the chunks of meat, sans skewers, are already seasoned, à la Addy. We can practically taste the sizzle.

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.”
