While Athens’ more upscale neighborhoods have recently rediscovered the gastronomic joys – and, let’s face it, the economic sense – of eating souvlaki, this classic dish has never gone out of fashion in Athens’ downtown. The city’s longtime souvlaki venues may have changed little in the last 50 years, but there is something particularly satisfying about their old-fashioned, no-frills approach. With their clientele of seasoned fanatics, the best of the bunch offer a lesson in what it truly means to eat like an Athenian. (Keep in mind that the menus at these old-school souvlaki places have remained virtually unchanged for decades, meaning that there is no chicken served, only the traditional pork or “kebab” – usually made with a mixture of minced veal, lamb and sometimes pork – in variations described in our Athenian souvlaki primer.)

Mushroom hunting has an irresistible, magical pull. Composer John Cage, an avid mushroom collector, found them an integral part of his creative process, once writing: “Much can be learned about music by devoting oneself to the mushroom.” Every fall, thousands of Catalans likewise find themselves under the mushroom’s spell, following the elusive fungus’s silent melody into the woods, a rustic wicker basket in one hand and – more and more these days – a GPS-enabled smartphone in the other.

Earlier in 2012, Jing’an Villas – a square, block-sized 1930s-era housing area in the heart of downtown Shanghai – survived an ironic plan that called for permanently relocating all of its 3,000-plus residents in order to better “preserve” the historic neighborhood. Luckily, the plan was shot down in a party committee meeting. For now, at least, Jing’an Villas remains the perfect setting for trying longtang cai, simple, home-style alleyway food that features local favorites.

The arrival of fall in Istanbul usually means one thing for us: hamsi season is about to begin. Hamsi, of course, are the minuscule fish (Black Sea anchovies) that Istanbulites are mad about, and the coming of fall and the cooling of the waters of the Black Sea mark the beginning of the best time of the year to eat the little suckers. In honor of hamsi season, we offer a list of six of our favorite places to try these tiny fish.

In the ’90s, as the first American burger and pizza chains began appearing all over Athens, it looked like the humble souvlaki was not the takeaway or delivery option of choice anymore. Luckily, the past 10 years have seen a huge comeback of souvlaki. Neo-souvlaki places that looked nothing like the greasy joints of the past started appearing all over Athens. The economic crisis has made the return of souvlaki even more poignant: people want cheap, tasty food more than ever, and souvlaki shops are opening up everywhere.

Dinner and a comedy routine isn’t a concept that has caught on in China. A few Sichuan restaurants feature a traditional show with the help of some loud music, a man with a flashy cape, and a mask with many thin layers that changes with a quick, hidden tug. But a Hunan restaurant? Never. At the popular neighborhood joint Hunan Xiangcun Fengwei, however, the finger-licking good food from Chairman Mao’s home province shares top billing with the subtle art of Chinglish menu translations that at first glance seem to defy explanation.

Like Clark Kent hiding his Superman tights beneath a brown suit and glasses, Klemuri maintains the appearance of a predictable Beyoğlu café – wooden tables, shelves loaded with knickknacks, Buena Vista Social Club on the stereo, spinach crepes and a crispy chicken salad on the menu. But down in the kitchen, out of public view, Klemuri’s alter ego – a spry Laz cook – is waiting to save you from another boring “café” lunch.

There’s nothing like a debate about “urban renewal” – often touted by municipal governments as a way to repurpose run-down urban areas for gentrification – to work up a good appetite. In a city like Istanbul, a teeming metropolis of 15 million people working to build a modern life among ancient ruins, these discussions seem to occur on every corn

Turkey’s take on the pizza comes in two distinct varieties. There’s the Arabesque lahmacun, a round, ultra thin-crusted snack topped with a shmear of finely ground meat and seasoning. Then there’s pide, a more substantial canoe-shaped creation that’s a specialty of Turkey’s Black Sea region.

With a menu from the frigid provinces that border Korea, Dongbei Siji Jiaozi Wang – literally, “The Four Season Dumpling King from the Northeast” – is all about hearty dishes to warm you up from the inside out. The further north you head from the Yangtze River, the more the temperate climate demands that wheat trumps rice as the staple grain, often showing up on menus as dumplings and noodles. Yet despite its eponymous claim to represent China’s Northeast, not even the Dumpling King can escape Shanghai’s astringent influence, specifically in the condiment selection. Here you dunk your boiled dumplings in vinegar and sweet chili pepper rather than the typical Northern garnish that adds soy sauce to the mix (or sometimes boldly goes it alone with no vinegar), occasionally coupled with roughly chopped garlic.

The sap of the spiky maguey plant has long been used by the indigenous peoples of Mexico to prepare pulque, a milk-colored, viscous drink that has roughly the same alcohol content as beer. When they arrived in Mexico, the Spanish were introduced to pulque. Used to imbibing harder stuff, however, the conquistadors experimented with distilling a mash made out of the maguey plant, in the process inventing the beguiling spirit known as mezcal. Previously a liquor considered the province of the poor and working classes, mezcal has in recent years become one of the trendiest and most popular alcoholic drinks in Mexico, with more than 150 different brands now on the market. (Tequila, made from blue agave – a kind of maguey – and produced within a specific region of Mexico, is the best-known member of the mezcal family.) The rise in mezcal’s popularity has led to a proliferation of mezcalerías, wine bar-like spots that specialize in pouring the drink. In Mexico City in particular, mezcalerías have popped up in nearly every neighborhood, and their numbers keep growing.

Editor's note: This week, Mexico City joins Culinary Backstreets as our fifth city. We're delighted to launch Culinary Backstreets: Mexico City and look forward to sharing our culinary discoveries in this captivating metropolis. The vast megalopolis of Mexico City is one of the most misunderstood and misrepresented cities in the world. Adventurous tourists are often surprised to discover a vibrant national capital filled with incredible architecture, beautiful weather and amazing food. In some ways, this scene has been playing out for 500 years.

Thwap. Thwap. Thwap. “Do you hear that?” asked Sean Roberts, an expert on Uighur culture and politics and our dining companion for the day. “They’re making the lagman.”

If there is a symbol of the adoring relationship that Greeks have with lamb, it is none other than the lamb on a spit that most Greeks in mainland Greece eat as a specialty on Easter Sunday. Greeks eat beef or pork at least once per week; lamb, however, is not an everyday thing but a treat, something more than just meat.

We like to think of Istanbul’s Grand Bazaar – open since 1461 – as the world’s oldest shopping mall. If that’s the case, shouldn’t the Grand Bazaar be home to the world’s oldest food court? That may be taking the analogy too far, but for us, the Grand Bazaar can be as much a food destination as a shopping one. As we see it, one of the hidden pleasures of going to the bazaar (once you get past the overzealous shopkeepers hawking souvenirs) is exploring some of its quieter back alleys and interior courtyards for new dining possibilities, especially some of the smaller restaurants that cater not to tourists but rather to the locals who work in the sprawling marketplace. Here are some of our favorite places.
