The oldest city in Western Europe, once the hub of a trading empire that connected Macau in the east to Rio de Janeiro in the west, Lisbon today feels staunchly Old World European, a sleepy town of nostalgic storefronts and scenic churches. But that’s only its façade.

Spain, Italy, Greece, Turkey, Portugal, Morocco, Tunisia – one thing that unites this swathe of the Mediterranean is olive oil, whose use in the Fertile Crescent can be traced back to 6000 B.C.E. Olives arrived in the southern part of the Iberian Peninsula around 9th century B.C.E. with the Phoenicians. Ancient Rome saw huge quantities of olive oil from Hispania Baetica (currently Andalucía) being transported throughout the Roman Empire in millions of amphorae (made in Baetica). Spain leads production of olive oil to this day, with 45 percent of the global total. The majority (65 percent) of Spanish olive oil production is sold to Italy, where this oil is mixed with others (normally of the same quality, but not always) and sold under an Italian label.

Barcelona’s food shops and colmados offer culinary treasures all year long, but the holidays are a particularly exciting time for browsing their wares. The festive window displays show magnificent gift baskets overflowing with tasty treats – with many Spanish and Catalan specialties among them. Perhaps the most desirable items in holiday gift baskets here are the seasonal sweets, which previous generations would amass in quantities that would serve as “emergency” treats for unexpected guests the rest of the new year. (Thankfully, one can now find these year-round, so there’s no need to hoard them.) We’ve written previously about artisanal turrón, which continues to be handmade by a few family-run companies.

With shops closing, pensions and salaries shrinking, and more and more Greeks feeling the pinch, it never ceases to amaze us that good food in the capital and elsewhere is still appreciated and faithful customers still abound. The restaurants below are just a few among the many wonderful, lively places that are managing to keep their standards despite enormous financial pressures. Their prices are affordable, their quality outstanding. Sea Satin Nino, Korthi Bay, Andros This is one of those restaurants that a Michelin Guide would rate not merely as “worth the trip” but “worth the detour.” Although it may take an hour’s drive from the port and half an hour from Hora, any meal at Sea Satin Nino is cause for celebration.

Is there a flavor more typically Greek than avgolemono, the smooth yet tart sauce that enriches dishes on virtually every restaurant menu in this country (apart from the souvlaki joint)? You’ll find it livening up soups of every description, poured over dolmades (wraps) of cabbage, vine leaves or chard and stuffed zucchini, thickening dozens of fish, meat, poultry and vegetable stews and fricassees. It marries particularly well with artichokes, in a famous delicate dish called anginares ala polita (or Constantinople-style), and binds the interesting innards in mageiritsa, the traditional fast-breaking stew-like soup eaten on Easter eve.

When we arrived in Tbilisi in 2001, there was one café/restaurant that was a beacon to those seeking an alternative to the traditional Georgian dining experience of stark rooms and banquet tables or greasy spoons with clunky tables and little stools. It was a funky little crooked house of pure originality that served the regular dishes, but with a personal homey touch that suited the place perfectly. Although it felt like a world apart, the art installation cafe was Georgian to the bone, being the creation of Rezo Gabriadze, the renowned artist, writer, sculptor and film and stage director.

Despite being home to Lisbon’s most photographed street, Bica has maintained its close-knit-community feel, with encroaching internationalization still held at arm’s length from these bumpy cobbled lanes and steep stairways. The small residences here have generally been passed down through generations, meaning a steadfast family vibe where everyone’s laundry is, literally, there for all to see. Estrela da Bica is a cozy, rustic restaurant at the bottom of this tiny hill district that perhaps marked the first sign of middle-class interest here. Historically inhabited by fishing families, Bica is becoming increasingly touristy by day and, thanks to the several bars around, more of a hangout at night.

We’d just about given up on hotpot, what with last year’s scandals of rat meat parading as lamb and opiates mingling with the Sichuan peppercorn to give diners a real buzz. But 2014 has seen the trend of farm-to-table dining hit Shanghai in a big way, spurred on by these food safety concerns. The most recent entrant to the organic dining scene is the aptly named Holy Cow. More than just a phrase made famous by Chicago Cubs announcer Harry Caray, Holy Cow is a healthy hotpot restaurant specializing in – you guessed it – beef, plus vegetables sourced from owner Anthony Zhao’s family farm. Loyal CB eaters might remember Zhao from his Shanghainese lunch hotspot Mi Xiang Yuan.

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.

A legendary snack bar sits on a corner of Praça Luís de Camões, a busy square dedicated to one of Portugal’s most celebrated poets (his most famous work is the epic Os Lusíadas, a fantastical interpretation of the Portuguese voyages of discovery, narrated in Homeric style). The square is a major thoroughfare in Chiado and witnesses thousands of journeys daily. Many passing through make a pit stop at O Trevo. This tiny and perpetually packed eatery has historical roots in the area; traces of the old sign, “Leitaria Trevo,” over the marble entrance reveal its beginnings as a dairy some 80 years ago.

Roughly a year ago, José, the owner of Das Flores, was heartbroken: he had just received an eviction notice demanding that he close the restaurant. And it’s not like he hadn’t been paying his rent – he had, but there were plans to transform the whole building into a luxury hotel. That has become a common occurrence in Lisbon’s recent history: closing an old family-owned business to make way for something more profitable to its landlords. Only this time the story had a different ending. With the help of a lawyer, José managed to keep his doors open. At least for the time being. He’s now a happier host, running the place behind the counter with his business-as-usual mindset.

September heralds the start of Portugal’s wine season, and while harvests from Alentejo and the north usually get all the attention, many forget that Lisbon itself also offers much to try from its own soil. This old wine-producing area was previously known as Estremadura, which extends from the capital to about 100 km to the north. In 2010, the rebranded Lisbon wine region (Região dos Vinhos de Lisboa) was born. Production has since expanded on average around 25 percent annually, with 70 percent of sales now allocated for export.

We recently spoke with travel writer Caroline Eden and food writer Eleanor Ford about their new cookbook, Samarkand: Recipes & Stories from Central Asia & the Caucasus (Kyle Books; July 2016). Eden has written for the Guardian, the Telegraph and the Financial Times, among other publications, while Ford has been an editor for the Good Food Channel, BBC Food and the magazine Good Food and currently writes about restaurants for Time Out. How did this book come about? Caroline Eden: It was an idea I was percolating for a long time, since about 2009. Travelling in Central Asia, mainly as a journalist but sometimes for fun, I got fed up with guidebooks dismissing the food in the region as “survival fare.”

For the last few months we’ve been obsessed with finding the best tacos de guisado in Mexico City. This is not an easy task because these types of tacos are abundant in a city where people are always on the lookout for inexpensive and fast eats. We have tried some amazing tacos de guisado throughout the years, but we keep finding new and delicious places in a city that never fails to impress us. A few months ago we started going to the Saturday Sullivan market for just one reason: eating breakfast at Los Barriles, a booth that sells between eight and 10 different types of tacos de guisado – usually ready-made stews served atop a tortilla – at a time.

Each morning, 82-year-old Giorgos Chatziparaschos’s bicycle pedals clank and echo down the cobblestone streets of the Venetian-era port city Rethymnon, on the island of Crete. For almost 60 years, he’s parked his bike in front of a 17th-century building where a simple hand-painted sign reveals his family name and his family business. By eight o’clock he has donned his apron and hat, and with the steely determination that underlies his work ethic, he begins to roll out the dough. Chatziparaschos is one of the only pastry makers in Greece specializing in handmade kataifi. The traditional phyllo pastry looks like shredded wheat, with strands as thin as vermicelli.
