Think of Ramadan, which just began in many parts of the world, as a kind of monthlong biathlon that consists of an all-day race to beat back the hunger and thirst of fasting, followed by an all-night marathon of eating and drinking in order to fortify the body for the next day’s fast. In recent years in Turkey, iftar, the traditional break fast meal that used to mostly consist of some dates and a freshly baked round of Ramadan pide, has started to become an increasingly trendy affair, with ministers, businessmen and regular people trying to make an impression by hosting ever more lavish meals.

Something special happens when the sun goes down. Night markets, whether in Southeast Asia or in the heart of Queens, inspire a thrill — we call it a sense of wonder — that brings boundless childhood summers to mind. We still feel it, on warm-weather Saturdays, when we ride the elevated 7 train to the Queens International Night Market. (It's a pain to park anything bigger than a bicycle near the market; we always take public transportation.) Many of the other passengers seem to be headed our way. Surrounded by fellow pilgrims, our anticipation builds as we descend from the train platform and march south. As we near the market grounds, and as the wind freshens and comes about, perhaps we catch the scent of sizzling meat.

When Japan’s last shogun ceded control of the country in 1868 and a centuries-old closed-door policy was reversed, foreign influences on the country grew from a trickle to a steady stream. Foreign residents were confined to restricted living areas, one of the largest one being in Yokohama, just south of Tokyo. Capitalizing on their fellow expatriates’ homesickness, some enterprising Westerners began importing or even brewing beer. In fact, the brewery that would become Kirin, one of Japan’s most ubiquitous tipples, was founded by a Norwegian by way of America in 1869 or 1870. As a domestic market for beer emerged, the Meiji government sent fledgling brewers to train in Germany and elsewhere, as well as brought in American advisors to help grow the industry.

On our culinary walk in the borough, you'll quickly realize that Queens is not just a paradise for different ethnic cuisine but also for street food! Approach with an empty stomach.

Entering Central de Cacao, one might think it any other café in the hip neighborhood of Roma Sur. Sitting upon stools, customers hunch over their laptops, sipping from steaming mugs. A wide, beautiful geometric design hangs on the high wall behind the counter. To the left of the entryway, colorful products for sale line a stack of long shelves. But upon closer inspection, the sweet nature of the cafe and store reveals itself. The contents of the steaming mug: chocolate. The geometric design behind the counter: molinillos, or traditional Oaxacan chocolate whisks. The products on the shelves: all chocolate. Chocolate-infused honey. 100 percent chocolate bars.

What the taco stand is to Mexico City or the wok-wielding hawker to Bangkok, the Würstelstand is to Vienna. At any time of day or night, people line up to snack on a quick sausage, with a pickle, mustard and a can of beer. There is an astonishing variety of sausages to choose from – from well-known Vienna sausage to Waldvierter, a twice-smoked sausage made from pig’s head, from spicy Burenwurst to Käsekrainer. The last one is for many locals the king of the Wurst: a coarse sausage filled with pockets of hot, melted cheese that ideally form a crispy crust on the outside once the sausage has been grilled.

The calango is a tiny lizard commonly found in the hottest, driest and poorest parts of Brazil’s Northeastern countryside, and in popular culture, the calango is also a symbol of hunger. Someone who eats calango is driven to do so because he has nothing else to eat. Thankfully, at Kalango there’s plenty to eat. Kalango (the “K” is for chef Kátia Barbosa, owner also of Aconchego Carioca) is a spartan botequim, or small gastropub, located near downtown that serves the specialties of Brazil’s Northeast states. This comida sertaneja, as it’s called, is very hard to find in Rio.

As you approach Maroussi by train, it is difficult to imagine that 100 years ago it was full of mansions with lush gardens – some still standing today – olive orchards and vineyards. Situated 13 km north of Athens, Maroussi (AKA Amarousion) was the home of Spyros Louis, the first athlete to win the modern Olympic marathon event in 1896. It is also where the modern-day Olympic Stadium and sports complex are situated. The train was connected to Maroussi in 1885, when it was also known as “the beast,” and it took three hours for the beast to make the trip from Omonoia.

There are certain places that experience the strange phenomenon where everything and nothing change at the same time. Take the example of El Racó del Mariner (The Sailor’s Corner), located for 40 years at the old fishermen’s dock in the port of La Barceloneta until it was forced to move when the area was turned into a marina for luxury yachts. Regardless, even at its new address in the modern Port Fórum area, reaching El Racó del Mariner requires that you cross a port police checkpoint, just as you had to at the old spot.

Many people think of miso as the soup that gets tacked onto every Japanese meal. We can still remember our first experience of Japanese food in the West, when the waiter brought the soup at the end of the meal, and someone thought he’d forgotten to serve it at the beginning. Any self-respecting Japanese meal, just about anywhere in the world, will end with miso soup. The miso used in the soup is a paste that will determine the flavor of the soup. There are basically three kinds of miso: red (akamiso), white (shiromiso) and mixed (awase), which has a brownish hue and is the most common variety used in miso soup.

These days, a good Portuguese-style savory pie is hard to find – even in Portugal. In a country with so many great examples, namely in Alentejo, Beiras or Trás-os-Montes, where pies (or empadas in Portuguese) are beautifully made, it’s disheartening that in Lisbon you’ll find mostly dull and dry versions or disappointing fillings within good pastry. Belmiro de Jesus, a native of Trás-os-Montes, one of the most remote and unspoiled regions of Portugal, always loved the empadas his grandmother would cook for special occasions or festive times of year, like Easter or the August village festival. So when he decided to open an empada-themed restaurant, he used hers as an inspiration but changed the format and developed a thinner pastry.

The rustic Neapolitan tarallo, made of 'nzogna (lard), pepper and toasted almonds, is a true delicacy. It can be considered the first popular snack in Naples, a bite that combines the punch of black pepper with the sweetness of almonds, the whole united by lard. It’s a dangerous combination for the waistline, that’s for sure. Taralli are offered to celebrate a new home, shared with friends during soccer matches, enjoyed with one’s significant other on the rocky shore, given to guests at parties, taken aboard boats (it’s the very height of yuppiness to eat them accompanied by iced spumante while out at sea). Until a few years ago, taralli were sold by tarallers, roving vendors who carried a basket full of taralli on their heads.

Oaxaca, consistently ranked as one of the three poorest of Mexico’s 31 states, can also claim the title of having the country’s worst school system. Demonstrations and rallies by students, teachers and unions are a regular occurrence in Oaxaca City, causing frequent gridlock in the center of town. The walls of the city in bold graffiti reflect the young voices of the social movement: sometimes, a mere angry scrawl, but more often, these are canvases that will move you to pause and consider these depictions of revolution, past and present. One such wall is on Calle Porfirio Diaz in the Centro Histórico. It’s the exterior of Espacio Zapata, the home of the Asamblea de Artistas Revolucionarios de Oaxaca (ASARO).

When Tonkatsu Hamachan first opened in 2001, it became an industry favorite – one of those places chefs, foodies and lifestyle journalists kept to themselves. Perhaps they closely guarded this spot because the dining room barely fit six tables, most of which were usually occupied by Japanese businessmen. The restaurant itself refrained from self-promotion – the shoji screen with hiragana script and a frosted glass door would have been as illustrative as a blank canvas to the mostly Japanese-illiterate pedestrians in the expat-friendly enclave of Jing’an. We lived just two blocks away from Hamachan for over a year when we first moved to Shanghai in 2007 and didn’t know about the tonkatsu genius until a friend drunkenly whispered the secret to us one night.
