Visiting establishments with a lot of history always warms the cockles of our heart – even more so when that establishment is the oldest surviving cantina in the city. El Dux de Venecia didn’t start out as a cantina, but it became a drinking establishment in Azcapotzalco – a farming community that became part of Mexico City in the 1940s – during the Mexican revolution and has remained an important part of the neighborhood ever since. The story goes that an Italian traveler decided to open a grocery store at the end of the 19th century. He named it El Dux de Venecia (The Doges of Venice) because he was originally from that Italian city. He offered all kinds of imported products from Europe as well as local ones, including deli meats, bread and alcohol. Because some customers consumed these items in the shop, the owner installed chairs and tables for their comfort.

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.

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.

Sweet, fluffy and incredibly habit forming, yakiimo (roasted sweet potatoes) are an autumnal treat loved throughout Japan. But in a small corner of Setagaya, Tokyo’s largest ward, a dedicated shop bakes them year-round. Kept busy by a steady stream of visitors, all clutching tell-tale paper bags, Fuji has a national take on a traditional snack. The slow-baked yakiimo are often sold from slow-moving mini trucks equipped with onboard wood-burning ovens. As the trucks roll by, they fill the air with both a comforting smell and familiar song. Roasted on a bed of stones, the potatoes are commonly known as ishiyaki imo and once saved Japan from famine when rice crops failed in the 18th century. Served without butter or salt, it may seem a little simple to the untrained eye, but cooked right, the flavor and texture render any additions entirely obsolete.

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.

[wptab name='Story']Up on the walls of O Frade’s polished interior is an old radio that catches the eyes of most clients. The music wafting from it is part of an illusion: “We hid the wireless speakers we use inside it because the radio doesn’t work anymore,”' says chef Carlos Afonso, who runs this small new restaurant alongside his cousin, Sérgio Frade. The radio came from their grandmother’s house and is there to remind them of the very long afternoons the two cousins spent around the dining room table, eating with their families. “That’s where we first learned to appreciate food,” Carlos recalls. Food has always been a serious subject for both. O Frade’s namesake is an old taberna that was run by Sérgio’s family members in their hometown of Beja during the ’60s. Back then, tabernas were a big part of the way of life in the Alentejo region, serving as meeting points where men gathered after work, to eat (a little), drink (a lot) and (when the mood was right) to sing the famous Cante Alentejano, polyphonic form of singing that UNESCO designated as an Intangible Cultural Heritage in 2014.

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.

Istanbul's Kurtuluş neighborhood is home to a number of slow-burners, establishments that may be hidden in plain view due to their plainness but that end up becoming some of our favorites. Gimmicks don’t fly in down-to-earth Kurtuluş, where neighborly ties are strong and home-cooked meals are preferred. Tucked on a side street in the middle of the quarter is a small eatery that exemplifies this tried-and-true character. Behind windows that fog up quickly in the winter sit a handful of tables facing an open kitchen in what might be Istanbul's coziest restaurant, Ben-u Sen, which showcases the divine ev yemekleri (home cooking) of the delightful Nuray Güzel.

You pass through the doleful Imeretian coal town of Tkibuli, wind 750 meters up the Nakerala pass and just as you catch your breath from the climb, you lose it again dropping down from the summit, for you have entered Racha-Lechkhumi, one of the most gorgeous regions in Georgia. We were first here in 2004, for an art festival organized by a local poet who had the unnerving habit of always speaking in verse. Since that mind-bending weekend, the regional capital of Ambrolauri hasn’t changed much. There is a new little airport, a few modest hotels, a couple humble restaurants, and a giant bottle of Khvanchkara that still stands in the middle of town, though it has been renovated. The vibe is as mellow as ever.

Walk through Lisbon’s Madragoa, a neighborhood of cobblestoned streets and small houses, and you are likely to be hit with the intoxicating smell of freshly roasted coffee. Follow the scent and you are likely to find yourself in an utterly unique spot: Flor da Selva, one of the last wood-fired coffee roasters in Europe. Manuel Alves Monteiro, from Melgaço in northern Portugal, founded Flor da Selva in 1950, and Manuel’s son, Jorge, and grandson, Francisco are keeping the family business alive and kicking via an artisanal method – one they started using many years before anything artisanal was trendy, mind you. “My father was a coffee lover,” says Jorge, thinking back to when Manuel first opened his shop. “At this time, we were drinking a lot of mixtures with barley or chicory that were inexpensive, but he could see the potential for 100% coffee blends.”

The downright whimsy of Filomila is hard to ignore – or resist. Perhaps it is the red exterior with the French-inspired script or the vintage bric-a brac and posters that cover the walls. Or it could very well be the sight of all the pies, sitting patiently by the window just asking to be eaten. One thing is sure, most of the shop’s allure stems from the energy of its owner, Efstathia, who four years ago decided to go rogue after working in various Athens restaurants and open up with just 3,000 euros to her name, against all advice from friends and family.

“What year did you marry your wife?” we ask Rafael Hernandez, known as El Negrito of Mercado Medellín, one Saturday afternoon at his vegetable stand. “I don’t know!” He breaks into uncontrollable laughter, “She knows though!” “What year did we get married, Gorda?” he asks the woman next to him. Her hair is tightly permed and her hands are ever-busy sorting vegetables and tallying accounts “I was 21 and you were 25, Negro – so more than 50 years,” Josefina says. Rafael, now 79, with a shock of white hair and an easy smile, happily bustles around his stand.

Saturday, late afternoon, Jackson Heights. In the shadows of the 7, the elevated train that runs along Roosevelt Ave., sunlight is already giving way to street light; music spills from passing cars and lively watering holes; a few men and women hurry along on neglected errands. More than a few step into La Gran Via Bakery, lured by a show-stopping array of cakes and a long line of display cases filled with individually portioned pastries. At the back counter, Betsy Leites is poised, pastry bag in hand, over a bright white tres leches cake rimmed with strawberries and peaches. She squeezes out a cursive "Feliz Cumpleaños."

Order a plate of vindaloo in one of the many Goan restaurants around Lisbon and your local friend at the table may point out that the origin of this dish is, in fact, Portuguese. Even the name can be decoded back to the Portuguese vinho d’alhos (wine and garlic), he’ll say. But let’s be honest here, amigo, vinho d’alhos has about as much to do with Goan vindaloo as the croissant does with the cronut. Vinho d’alhos may have sailed off to Goa along with Vasco da Gama in the 15th century, but when it returned to Lisbon with Goan migrants in the 1960s and 70s, something had changed. It had gone Goan.

If Mexico had to choose a national flavor, the chile pepper would without a doubt be the winner. The only issue might be which chile would take the top spot in such an honor. The country is home to more than 200 variations of chiles, stemming from some 64 distinct varieties. Almost no meal is eaten without some form of chile-based salsa. And while the variety of chile ranges from eye-twitchingly spicy to robust, sweet and smoky, seeking out a dish in Mexican cuisine that doesn’t incorporate at least one type of chile would be a difficult – if not futile – venture. When FIFA held the 1986 World Cup in Mexico, the official mascot was Pique, an anthropomorphized green chile pepper wearing a sombrero. The meaning was not lost on the world, and least of all on Mexico itself. Let it be known: Mexico is home of the chile.
