Numerous wines and craft cheeses are enjoyed on our Greek Wine's Rebirth, Uncorked walk, where some of the country's most exciting up-and-coming wines are presented alongside perfectly-paired snacks.

When people think of rice and Spain, they think of paella. In Barcelona there are hundreds of places to eat paella. And every Thursday you can find it on the menú del día at most restaurants across the city. There’s more to Spanish rice dishes than just paella, though. The word “paella” didn’t even appear until the 18th century; recipe books from the Middle Ages talk only of rice, and particularly the Valencian and Catalan kinds. In fact, “paella” originally referred to the pan used to cook the grain, but eventually came to describe the dish as we know it: rice prepared so that the water or broth completely evaporates and sometimes is left with a toasted layer on the bottom. But enough about paella!

For the most part, Mexico City pampers its citizens with year-round warm, sunny weather, give or take the occasional downpour in the rainy season. And like any spoiled child, chilangos have grown so accustomed to living in such a temperate clime that any slight deviation registers as almost unbearable. At 19 degrees C, pedestrians cloak themselves in winter coats and hurry down the sidewalk, worrying that they will freeze to death on the two-block walk from their parked car to their front door. It’s rumored that chilangos are so unused to seeing their own breath in the cold that they mistake it for their souls escaping their bodies, augmenting their hatred of frigid weather.

Tapas of artichokes and prawns with mushroom paste in a Sant Antoni bodega are among the numerous treats encountered on our walk of Barcelona's iconic bodegas.

Istanbul's conservative Fatih district has perhaps the highest concentration of Syrian refugees in the city, and the tree-lined Akşemsettin Street boasts a staggering number of Syrian eateries, from spacious sit-down affairs with full menus to hole-in-the-wall, standing-room-only kiosks slinging shawarma, fried chicken, and falafel. Having popped up rapidly amid the waves of Syrians fleeing the devastating civil war that has displaced more than half the country's population, these establishments have made a firm imprint on the culinary scene. While the falafel at many of these places is a mediocre afterthought overshadowed by the more popular poultry-based items, we found one counter offering falafel and falafel only, serving up a generously crafted sandwich the size of a chubby child's forearm for a measly TL 2.50 (US$0.75).

Avenida da Liberdade is commonly acknowledged to be the most luxurious and expensive artery in Lisbon. It’s the obvious place to go to buy a famous designer’s dress or fancy jewelry. It might be surprising to learn, then, that it’s also the place to go for good pernil assado (roasted pork shank) or cabidela (chicken blood rice). The reason is simple: the area is filled with great tascas, which draw a wide range of local office workers, including lawyers, business consultants, public servants and unpaid interns. Among these tascas, O Cartaxinho is one of the best, if not the best. Unsurprisingly, it’s also one of the most popular – it’s not unusual to see groups waiting outside for a table during lunchtime.

Anticipating a line, we arrived ahead of our appetite, but the slightly acrid smell of fresh dashi wafting over the street hurried our hunger. Tucked behind a handful of confounding corners southwest of Shinjuku Station in a mixed-use neighborhood of apartments, shops and offices, Udon Shin has consistently ranked among the best udon restaurants in Tokyo since opening in April 2011. At around ¥1000 (US$9) per meal, you feel like you're getting away with something. Owner and chef Shinji Narahara deftly handles the classic accompaniment to udon (think homemade dashi, deep-fried tofu and tempura) but elevates the humble noodle to modern heights with their trademark carbonara udon.

Fall is in full effect in Istanbul and its our favorite time of year (not that there is a bad time) to hunker down in a meyhane around some rakı and meze. Our meyhane walk stops at three of our favorites and involves the sampling of no small amount of both.

Baijiu, which translates literally as “white alcohol,” is a clear spirit made predominately from sorghum, although glutinous rice, maize or other grains can also be utilized in various proportions. It is ubiquitous in China at official events, like weddings, business deals, and boozy government lunches, but under President’s Xi Jinping’s ongoing crackdown on government largesse, sales are down about 13 percent from a peak in 2012. As baijiu growth falters, many brands are looking abroad to push sales – not only to introduce it to foreigners, but also to keep it relevant to the younger, wealthier generation of Chinese who are living as expatriates.

Hidden behind the imposing stadium of the Panathinaikos football team – the green team as opposed to its eternal rival, Olympiakos, the red team – lies a tiny eatery that recalls Athens before the 1960s, when urban sprawl destroyed everything. Occupying two adjacent whitewashed houses, Oinomagereion to Trifylli, named after the team’s clover logo, has been serving simple, delicious food to loyal customers for the last 60 years. The taverna was founded in 1962 by Kyria (Mrs.) Koula, the present owner’s mother, in order to earn additional income for her family.

Some of the best tacos in Mexico City are found on the street, and they are among the delicacies sampled on our Mexico City, Street Food Paradise walk.

“I don’t want to be famous, I just want to do my best and make good food. You have to work with honesty, from the heart,” Salem Kabbaz tells us. Born in Damascus in 1945, Kabbaz is smiling and animated as he chats with friends and suppliers and walks in and out of his restaurant in the Barrio Gótico. A very small, discreet sign above the door marks his eatery, El Cocinero de Damasco – the Damascus Cook – which is devoted to Syrian specialties like shawarma, hummus and falafel. Neighboring residents and City Hall workers come for take away or to eat at the few tables inside the small eatery.

Rio’s bar culture is crazy for chicken. It’s common to see at bars dozens of the cooked birds laying within heated glass cases, awaiting hungry customers. The more popular the botequim, the more parts of the chicken are available. In the fancy bars of Ipanema and Leblon you can only find voluptuous breasts and legs, accompanied by salads and risottos. But in more humble botequins in the North Zone or further out in the suburbs, you’ll find gizzards, feet, beaks, and even rear ends. Yes, cu de galinha is a rare delicacy in Rio... Not only is every part of the chicken appreciated, but also all ages of the bird.

Among the deep array of goods found at Tbilisi's Dezerter's Bazaar, the focal point of our culinary walk in the city, is a formidable selection of colorful and tasty pickles.
