Día de los Muertos (Day of the Dead), or at least some variation of it, has been an annual celebration in Mexico for over 3,000 years. During the Aztec period, it took the form of a festival in August dedicated to Mictecacihuatl, otherwise known as the Lady of the Dead. Today it is one of Mexico’s most colorful holidays, encompassing popular traditions both old and new. To the Aztecs, death was nothing to be feared; it was but a passage and a continuation to the next level of consciousness. Life was viewed as a state of dreaming and death was when someone was truly awakened from their slumber. The Aztecs’ monthlong festival was meant to honor those who had passed on and to entice their souls to visit once more.

In September of last year, Shanghai eaters were shocked when Mr. Wu shuttered A Da Cong You Bing, the city’s best scallion pancake shop. The only explanation for the abrupt closure was a worn sign on the door that read: “My family has a problem. The stall will be closed for a few days.” But this wasn’t the whole truth. Some attributed the shutdown to the fact that the stall was featured on the BBC program Rick Stein’s Taste of Shanghai, claiming that it had drawn too much attention to the unlicensed vendor and the government had taken note.

Greeks love going out till late, even on weekdays, so it’s no surprise that Athens is legendary for its nightlife. There are bars to suit every taste: bars with a great view, bars by the sea, mainstream bars, bars with great cocktails or music, etc. But for us, the really special bars are the ones that fly under the radar, bars that feel like a real discovery. We’ve done our homework and found some of the best of these “hidden” bars. Just between us, of course.

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.

Julian Ramirez started out at the age of 14 as a shop boy at a busy bakery in Colonia Guerrero in 1959, then a bustling blue-collar neighborhood, easily connected to downtown by streetcar. Back then, at La Antigua del Guerrero, he learned the business: wiping windows, sweeping up and eventually making deliveries on his bike. One nibble at a time, he picked up the art of cake- and bread-making from the shop’s master bakers. Those trade secrets would serve him over the next 63 years and beyond as they pass on to his kids and theirs. Many of Mexico’s classic bakeries like the Guerrero operation fell one by one with the introduction of mass-produced bread, tearing at a staple of communities across the capital.

Barcelona continued to thrill this year with its seemingly never-ending possibilities for great eating, from ambitious family-run eateries to neighborhood restaurants steeped in Catalan traditions to world-renowned temples of gastronomy. Granja Elena With its great gastronomic aspirations and a solid foundation in farm-to-table cooking and traditional Catalan recipes, this small Zona Franca granja (literally “farm”), which was been passed down through three generations, has gone from a simple shop serving breakfast and snacks to a full-blown restaurant and total culinary wonder. Run by the Sierra-Calvo family since 1974, Granja Elena is now helmed by the third generation, who are all industry professionals: Borja runs the kitchen, Patricia the wines and Guillermo the dining room.

One of our most exciting discoveries this year was Yılmaz Tandır Evi in Istanbul's Feriköy neighborhood, where many people from the eastern Anatolian province of Erzincan have settled over the years. Yılmaz İngeç, a native of Erzincan's İliç district, serves only the finest ingredients from his hometown, including fresh honey, kavurma and tulum peynir, a salty, crumbly cheese aged in goatskin. A simple serving of fried eggs topped with tulum was a match made in heaven, perhaps our favorite breakfast this year. We were thrilled to stumble upon a secluded slice of the Black Sea province of Trabzon right here on the Asian side of Istanbul earlier this fall.

Located just beneath Istanbul’s first Bosphorus Bridge in the Anatolian side district of Üsküdar is a secluded slice of Trabzon, the Black Sea province known for its otherworldly lush green forests, hot-tempered inhabitants and distinctly deep cuisine. The Trabzon Kültür Derneği (Trabzon Cultural Association) is something of a clubhouse for folks who grew up in the province and later moved to Istanbul for school and work. Founded in 1970 and having changed locations a number of times, the association set up shop in Üsküdar’s Beylerbeyi neighborhood at the turn of the millennium and crafted a miniature version of home in the heart of Turkey’s largest, ever-sprawling city.

Despite the 1970s-era sign outside that says Granja (farm) and the red letters spelling “Bar” inside, you can’t really tell what this place is until you open the menu: a temple of “neighborhood haute-cuisine.” The food at Granja Elena sounds simple but tastes rich and complex. The restaurant is a family business, now run by the third generation – Borja, Patricia and Guillermo Sierra Calvo – in the same barrio in which it was founded in 1974, La Marina del Port. This modern neighborhood is part residential and part industrial, a bit far from Barcelona’s center, located near the merchant port behind Montjuic and on the way to the airport.

Ramadan fasters in Istanbul may not love the endless daylight hours in summer nor the susuzluk (no water), but when the reward is a leisurely iftar under the trees on Kadinlar Pazar, the pedestrianized market known as Little Siirt (named after the southeastern Turkish city where many of the local shop and restaurant owners hail from), it must surely seem worth it. A February iftar would not be quite the same, at least not in Turkey. As we walked through the twilight to Siirt Şeref Büryan Kebap Salonu at the end of the square last Saturday, hundreds of fasters waited in front of cling-filmed plates of iceberg lettuce and ciǧ köfte for the Ramadan cannon to signal “breakfast” time.

When the nationalist Kuomintang army retreated to Taiwan in 1949 after losing to Mao’s communist forces, the island experienced a sudden influx of immigrants from around Mainland China, many ripped from their homeland and moved into crowded, hastily-assembled housing complexes. These gave rise to tenement communities, called military villages (眷村, juàncūn). During the years after the war, these new immigrants kept the memory of their hometowns alive, recreating the dishes of their childhood but – out of necessity – using local ingredients and adapting the recipes. Out of this homesickness arose a new type of Taiwanese cooking called Military Village Cuisine.

For more than six decades now Café La Habana has served great coffee from the state of Veracruz and also sells the beans by the kilo. As in many Mexican restaurants, it offers café lechero, which is one or two shots (depending on the customer’s preference) of very strong espresso in a large glass that is then filled up with hot milk. One of our favorite drinks here, however, was the café bombón (roughly translated as “marshmallow coffee”), a cortado double espresso shot with ground coffee sprinkled on top.

Wave after wave of migration from Anatolia has bestowed upon Istanbul a population of 15 million at bare minimum, with countless pockets of the city representing villages and districts from every last corner of the country. In the neighborhood of Feriköy, those originally hailing from the eastern province of Erzincan have managed to consolidate their presence on an entire street. Lined with a number of restaurants and shops selling fresh goods typical of the province, and a row of village associations established for the purpose of maintaining cultural ties between those living in Istanbul and their relatives back home, Feriköy's Gediz Sokak is all about Erzincan, a land of sheep and mountains famed for its dairy products.

Our “Culinary Secrets of the Old City” walk goes beyond the major monuments and into the backstreets where all of the serious eating is done. We’ll set off through the atmospheric, lesser-explored market streets around the Egyptian Spice Market and then go deeper into the untouristed Fatih neighborhood.

Although, thanks to its once flourishing silver and gold mines, the north-central Mexican state of Zacatecas was an economic powerhouse during the colonial period and the early years of the Mexican republic, its cuisine is not as well known in Mexico City as that of states such as Oaxaca and Michoacán. But when we headed this past New Year’s to the state’s eponymous capital city, we were blown away by its food, as well as its history and beautiful colonial architecture. Zacatecas played a significant role in Mexico’s economy during the colonial period: When the Spanish conquistadors learned about the region’s rich mineral deposits in the mid-16th century, they started mining operations immediately. In 1585, the city that had grown from the mining settlement was recognized by the Spanish crown and called the “Muy Noble y Leal Ciudad de Nuestra Señora de Zacatecas.”
