Portugal’s great 19th-century novelist José Maria de Eça de Queiroz was ahead of his time in many ways, dealing with raw subjects like incest, abortion and priestly sex crimes in his books. Yet Eça de Queiroz, a renowned bon viveur, also peppered his writings with less controversial culinary references. In fact, one of his best-loved scenes features the main character tucking into roast chicken and rice with fava beans. It’s a fictional meal that Restaurante de Tormes, a restaurant in the hamlet of Santa Cruz do Douro dedicated to serving dishes associated with the author, has turned into a reality.

Lunch at Casa Guedes is one of our favorite culinary rituals in Porto: After snagging a seat at the bar during the midday rush, we sit, mesmerized, as Mr. Cesar nimbly cuts slices of roasted pork shank, then places them on bread and moistens it all with his secret sauce. While not the only item on the menu, the famous sande de pernil (roast pork sandwich) is Casa Guedes’s raison d’être. After taking in Mr. Cesar’s entrancing sandwich-making choreography, we order the upgraded version of the sande, which is topped with gooey queijo Serra da Estrela, a creamy sheep’s milk cheese. Seating at this humble and low-cost eatery used to be minimal, and Casa Guedes’s popularity had long outstripped its capacity – fans could be found waiting patiently in queues stretching down the block.

Corn is so vital to Mexican cuisine and culture that we could scarcely avoid it even if we wanted to. Not that we would ever want to – one of the things we love most about dining in Mexico is the high likelihood that our meal will have a healthy dose of corn in one form or another. Take atole, a traditional beverage made of corn flour, fruit, spices, and milk or water, which is often sold alongside tamales, corn patties most often stuffed with meat or veggies, steamed in a corn husk or banana leaf. Wash down your corn with some corn; that’s the Mexican way.

The market plays an important role in Mexico City’s daily life, not just because of its vendors but also because of its food makers – these market districts are home to a dizzying mix of street food sellers and small specialty restaurants. We sample some of these treats, tacos included, on our Market Watch walk.

In a few years time, one might look back at the year 2019 and feel a bit sorry for it. That’s not for lack of delicious things to eat: record numbers of restaurants continue to open – although fierce competition means around half shut their doors within two years. But 2019 risks being forever overshadowed by 2020, when Tokyo will host the Olympics and Paralympics for the first time since 1964. It certainly is a preparatory year for the anticipated influx of overseas visitors. Fortunately, the city was able to lay claim to hosting the Rugby World Cup and did very well, both at demonstrating Japan’s omotenashi (hospitality) at its best and in the national team beating Ireland, causing one of the biggest upsets in the tournament’s history.

In Shanghai, robot restaurants (and grocery stores) were all anyone could talk about in 2019. Well, that and bubble tea shops. But we love that there are still thousands of mom-and-pop restaurants serving traditional foods that are handmade and well loved, if you know where to look. So next time, skip that trendy, US$100-a-head hotpot joint where you still have to queue for an hour after your reservation has passed, and try your local noodle joint. Of course, you’ll probably scan the QR code on your table to order (and pay), and you won’t even chat to the staff until they put your dishes in front of you – after all, it is 2019 in one of the most tech-forward cities in the world.

It’s almost 2020, and Mexico City continues to be one of the best eating cities in the world. So maybe you won’t find world cuisine the likes of New York or London, but instead you will be bowled over by a deep culinary tradition, genius chefs who were self-taught and a delicious meal waiting on every corner (and we mean every). No “best of” list will ever cover all the deliciousness awaiting you in Latin America’s foodie megalopolis, but here are a few places that we fell in love with in 2019.

Holiday traditions in Greece, like so much in that country, are rooted in ancient Greek and Roman customs – pagan, of course – that evolved through Byzantine times and were adapted with the advent of Christianity. More recently, the westernization of Christmas and New Year celebrations has made those holidays here look more like the globalized version of them, for better or for worse. Greeks like preserving their old traditions, however, and some customs still persist, even if many Greeks don’t know where they came from. The Christmas season, known in Greece as Dodekaimero (twelve days), officially begins on December 24, includes the celebration for the New Year and ends on January 6 with the huge celebration of Theophania (the baptism of Jesus Christ by John the Baptist).

On our Hidden Flavors of the Hillside walk, we explore Lisbon’s historic neighborhoods of Mouraria and Graça. While the smell of change is in the air here – new communities are sinking roots and new restaurants are opening – we also visit traditional spots, like the city’s oldest coffee roaster, a third-generation family business.

Location, location, location is a familiar mantra of New York real estate; invariably it comes to bear on restaurants and other food businesses, too. When e-commerce giant Amazon decided not to build a second headquarters in Long Island City, many food vendors were disappointed, sometimes bitterly, at the loss of a possible 25,000 new customers. With an eye on the lunchtime rush just across the Hudson River, in Manhattan, they wondered, why not in Queens? By contrast, continual development in Flushing, albeit on a much smaller scale, continues to displace many small businesses. The food stalls in the lower level of the celebrated Golden Mall shuttered in late summer for a renovation that was planned to last several months; it seems nowhere near completion.

Editor’s note: We’re celebrating another year of excellent backstreets eating by reflecting on our favorite meals of 2019. Starting things off is a dispatch from Alexis Steinman, our Marseille bureau chief. This year began with a bang, when Marseille nabbed a coveted spot on the New York Times’ “52 Places To Go in 2019” list. Written by food writer Alexander Lobrano, the blurb lauded the city’s ever-expanding food scene. Throughout 2019, new restaurants opened, captained by chefs who trained at local tables, first-timers emboldened by the city’s entrepreneurial energy and Parisians seeking sun and the easygoing vibes that go along with it.

In the tale of Don Lázaro El Viajero, a Spanish Jew named Lázaro L. Torra, escaping the fascist advance in that nation’s civil war, fled in 1939 to Mexico City – one of tens of thousands that then-President Lázaro Cárdenas invited to find refuge in Mexico amid the black conflict of that war. By 1944 Torra had become something of a restaurateur/maestro, teaching kids in a kinda-working-class, kinda-middle-class neighborhood to speak in English and improve their Spanish and feeding them some decent grub in the same go. (The name of the restaurant, Mr. Lazarus the Traveler, has to do with its proximity to a road heading out of town before the city went all crazy huge and viral.) That was the deal. You got food, but you had to learn something in the process.

So ubiquitous as to be rendered almost invisible, the sticky bottles of soy sauce that decorate every table, counter and shelf in Japan are never far from reach. Both an ingredient and a condiment, there isn’t a chef in the land who would begrudge a diner a dash of the sleek black sauce – be it at a Michelin-starred sushi restaurant or a back street ramen joint. While the bottles are often slung behind stacked menus, their everyday presence is no sign that their contents should be underestimated. As common as table salt but infinitely more complex, the sweet, salty mix offers a glimpse of the sought-after umami flavor Japan is famous for.

On a blustery, drizzly winter afternoon in Istanbul, Muhittin Öztürk swipes his cell phone until he finds the photo he’s looking for: three men clad in blue aprons, standing behind a grill inside a small fishing boat. “That one’s my father, that one’s my uncle,” Öztürk says, pointing at the image. “This is the culture I come from.” Now a 35-year veteran of the business, Öztürk is the owner of the Derya, one of three gaudily adorned neo-Ottoman-style vessels moored to the shoreline in Eminönü, where a crew of cooks and waiters serve up fish sandwiches – balık ekmek (literally, “fish bread”) in Turkish – at a rapid pace to heaving crowds, most of whom are tourists.

A philosophical bar with a throwback name, Cuccuma Caffè opened in October 2018 as a counterpoint to the Neapolitan coffee culture – unlike the many, many bars where you sling back a shot of espresso while standing at the counter, this spot prioritizes a slow coffee. Achille Munari, 32, fell in love with Naples when he arrived 10 years ago from Umbria and decided to stay here in our city. A brilliant guy, Achille prefers a calm, relaxed pace of life, one that allows for reflection and conversation. So he decided to set up a bar that puts his life philosophy into practice.
