When the colder temperatures arrive, we stop by Lello’s stand for octopus soup, a beloved winter street delight for generations. Called the tea of Neapolitans, it’s a hot drink that tastes of the sea, as the water is flavored by the long boiling of the king of cephalopods. Discover Naples’ iconic street foods on our walk.

The backstreets of Istanbul's Osmanbey quarter are loaded with fabric shops, while the adjacent thoroughfare of Halaskargazi Avenue is a busy shopping area lined with chain clothing stores and hotels. Come here for a cheap shiny suit, but don’t expect to find rewarding culinary adventures, as most of the area's restaurants offer fast food that manages to be both overpriced and underwhelming. Given all that, we were thrilled when Mahir Lokantası rolled onto the scene in 2015, bringing to the table a fine-tuned rotating menu featuring daily regional specialties from every corner of Turkey. “We make a variety of dishes from the Black Sea region, the Mediterranean and Aegean coasts and Eastern and Central Anatolia,” Mahir Nazlıcan, the restaurant's namesake and head chef, told us.

When the couple Juan Pérez Figueras and Mercè Roselló bought in 1991 what is now Restaurante Agullers, it was an old run-down bar in the inner streets of Born, a neighborhood near the Port Vell area. “When I got the place it was totally ruined,” Juan explains. They decided to keep open only a long and narrow front section, creating a small bar-restaurant that specialized in fresh fish. All food was made in front of the clients, on a tiny grill behind the bar. This miniscule spot offering grilled fresh fish really struck a chord, and by the end of its first decade in business, people were lining up at the door.

A symbol of abundance and fertility, of good luck and wealth, of life and death, pomegranates have played an important role in Greece since antiquity. With their beautiful, crowned shape, this fruit figures heavily in Greek mythology, connected as it is to the goddesses Demetra, Persephone, Hera and Aphrodite. Apart from their symbolic meaning, pomegranates are also highly praised for their wonderful flavor and remarkable health benefits. Grown in abundance in Greece, there are many varieties available, with the most popular being Ako, Wonderful, and Hermione. The latter has an exterior that is almost pale yellow in color, and its seeds are paler too, but large in size, juicy and very sweet.

Sunday is traditionally a day of leisure for the average Greek, dedicated to two important aspects of life: food and family. Most Greeks enjoy the largest meal of this day at lunchtime, sharing it with an extended family that usually includes children, cousins, grandparents and aunts and uncles. On this walk – our own take on a classic Athens Sunday – we will start off at a leisurely pace, enjoying the quiet streets of normally bustling downtown. At our first stop, a dairy bar that has been around since the 1930s, we’ll get a taste of true Greek yogurt, topped with nuts and honey, as well as of galaktoboureko, a traditional custard-filled dessert sandwiched between syrupy layers of phyllo. Crossing Aiolou Street – one of the oldest paved roads in Athens, dating back to the 3rd century – we’ll walk past buildings and monuments representing the breadth of Athenian history and then catch a glimpse of parishioners at a nearby Greek Orthodox church as they leave the Sunday service. From there we’ll continue to a local spot where we’ll taste loukoumades, small balls of fried dough drizzled in honey that are traditionally enjoyed at weddings, while in a neighborhood spot that serves regional delicacies from across Greece we’ll sample ladenia, parcels of dough filled with feta, capers and chopped tomato, a specialty of the small Aegean island of Kimolos.

One of the many charms of daily French life is the ability to eat and drink well without needing beaucoup bucks. The best place to put this in practice is at a bar à vin. Since one never drinks alone in France – literally and figuratively – these bars always offer something to snack on. Sometimes, it’s simply a plate of cheese or charcuterie to soak up the wine. Other times there are more substantial plates that alone are worth a visit. The unpretentious Les Buvards, one of our favorite bars à vin in Marseille, exemplifies the latter – an impressive feat since the kitchen is barely wider than a wine barrel.

It’s been three years since that fateful windy day in December when Nacho, a friend of ours who usually prefers the quiet of his house to popular cafés or crowded bars, suggested we have a soup at Kadıköy Çorbacısı. Together with a couple of shops selling knockoff shoes and the back entrance of a famous American fried chicken restaurant, this soup spot occupies the ground floor of an ugly building located on an eerily silent alley by the Boğa, the trademark bull statue considered to be the symbol of Kadıköy. Anticipating the warmth awaiting us inside – evident from the fogged-up windows – and eager to thaw our body with some soup, we entered the restaurant with high expectations, which were resoundingly met.

You are motionless, stuck in a traffic jam after a long day at work while your stomach growls. You know the rest of the family will be hungry when you get home and that the fridge is empty and sad. Shopping and cooking is out of the question, so you turn onto a Vera side street, zig-zag through one-way lanes to Tatishvili Street, double park, and run into a tiny gastronomic oasis that has been saving lives like yours for nearly a decade. Its name is Tartan. Located in a step-down ground-floor apartment, takeout cafeterias don’t get homier than this. The front room is taken up with a long counter of refrigerated display cases half filled with enough ready-made dishes to lay down a feast when you get home.

For the most part, hamburgers in Mexico City disappoint. The accepted bread-to-beef ratio is shameful, with slender slices of overcooked meat hiding somewhere within the pillowy fluff of too much bread. The stringy, flavorless beef underwhelms. Even worse are the fancy sandwiches one finds at upscale burger joints, where blue cheese and spinach and a dozen other inappropriate ingredients only momentarily distract from the aforementioned defects of bad meat and a surfeit of bread. Against this dim backdrop of underachievement, the hamburgers at the Legión Americana shine like stars. This is something of a surprise considering the no-frills, dive bar atmosphere here.

One tip often given to travelers is to look for restaurants full of locals. In fact, we do the same thing when dining out in Naples: If we see a spot packed with groups of employees or policemen on their lunch break, it’s almost a guarantee that we’ll eat well. Trattoria Avellinese, the late Peppino (Giuseppe) Cipriano’s restaurant near the central train station, is one place that’s always crowded with Neapolitans. Moreover, we can personally testify that this trattoria is a local favorite. Growing up, we lived near Piazza Garibaldi, and whenever our family went out for lunch – which, to tell the truth, wasn’t that often – we went to Peppino’s place.

On our Xochimilco walk, we learn about the one-of-a-kind agricultural system in this UNESCO heritage site. Called chinampas, the island plots of farmland between the canals were first built by the ancient Toltecs when the area was on the edge of a long-gone lake. Today they are still used to feed nearby Mexico City.

Few places conjure more vivid images of delicious, cult meat consumption than Vari, a southern suburb of Athens, particularly the neighborhood of Vlahika. How, exactly, Vari became a meat-eating paradise goes back to members of the nomadic Sarakatsani tribe, who used to move their herds from the neighboring mountains of Parnitha and Penteli to spend the winter in this area, with its milder clime. In 1917, a few Sarakatsani families decided to make Vari their permanent residence. Later down the line, in 1962, Christos Goulas opened the first butcher-taverna called Tseligas (the name for a sheep herder) on Varis Koropiou Avenue (now called Eyelpidon, it’s one of the main drags in town).

When we think of Spanish convent pastries, we imagine a group of old nuns gathered together in the dark and humble kitchen of some small Gothic or Baroque cloistered convent, hidden away in the old part of town. We picture them working quietly, baking elaborate, time-consuming treats from ancient recipes that have been passed down over the centuries by the previous nuns who lived there. Yet when it comes to the only convent in Barcelona that still makes sweets to support themselves, we should throw our biases out the window – Santa Maria de Jerusalem defies all stereotypes.

It only took three years for Alibaba’s made-up shopping holiday on Singles Day, originally a joke celebration created by students in Chinese universities in the 1990s, to exceed Cyber Monday and Black Friday’s sales figures – combined. Since 2009, massive discounts have been offered annually on November 11 (11/11 – one is the loneliest number, after all). In 2019, sales on Alibaba topped US$38 billion in a 24-hour period, blowing last year’s record – US$30 billion – out of the water. In case there’s any doubt as to the importance the company places on the date, this year Taylor Swift performed at the gala evening that coincided with the day’s online sales activities.

On this week-long seafood pilgrimage, we’ll delve deep into the world of barnacle hunters, oyster fisherman, lobster trap builders, razor clam-diggers, and net menders, along with the local chefs who are harnessing the incredible offerings of their coast, transforming Galician cuisine into something new and exciting.
