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.

To call Tacos & Deli, a one-year-old family-owned spot in the popular nightlife district of Zona Rosa, small would be an understatement. The main dining area contains six little tables, a tiny kitchen, a taco station and a cashier stand, all of which are squeezed into a micro-sized area that in many other restaurants would probably end up being used as a broom closet.

When Yi Sheng Yue Wei opened on Yongkang Lu almost three years ago, its neighbors were pajama-clad retirees, a mahogany furniture workshop and the Shikumen History Museum – which, to be honest, is actually just one history buff’s storied alleyway house. Now the two-block street is one of the most laowai-gentrified in Shanghai, with bars run by French interns, coffee shops stocked with beans from Ethiopia and competing fish-and-chips shops. Rents have skyrocketed, and there’s even talk of transforming the thoroughfare into a pedestrian street. But amongst the hustle, bustle and inebriated foreigners, Yi Sheng Yue Wei remains, loyally serving the same home-style Cantonese food as it did when it first opened.

The perfect burger, or rather the perfect American-style greasy spoon, has long been the holy grail of expats and locals in Athens. There have been a number of places that have gone after the title of the Athenian burger king over the past 30 years, usually in the affluent southern suburb of Glyfada, home to a U.S. military base in the 1980s, but none have had lasting power. The military base has been closed for some time now but the appetite for American diner-style food (the kind popularized in what have traditionally been Greek-owned diners) has not abated in the least. Enter New York Sandwiches, opened less than two years ago near Pyrgos Athinon (pyrgos means “tower”) – the only skyscraper in central Athens – in the busy area of Ambelokipoi. With a menu that includes burgers, bagel sandwiches and Philly cheesesteaks, old-school letter boards hanging above the counter listing what’s on offer, and pictures of New York on the walls, the restaurant works hard to bring a bit of America to the heart of Athens.

We can’t prove it, but we suspect a network of tunnels lies underground in Beyoğlu that connects most of the meyhanes of Asmalımescit and Nevizade Sokak to the same mediocre kitchen, resulting in unexceptional mezes at scores of venues in this dining district. Following a number of tips, our search for a standout meyhane led us to the unassuming Asmalı Cavit on Asmalımescit Caddesi, where we’ve consistently had outstanding food. This traditional meyhane bucks the trend toward mediocrity with subtle but significant tweaks that, for us, make the meal.

There is literally nothing like a bowl of steaming má là tang (麻辣烫) when Shanghai’s wet, cold winter sets in. In English, it translates to “mouth-numbing spicy soup,” and if that weren’t indication enough that it will get your sinuses going, then the fire-engine-red broth certainly is.

Culinary Backstreets’ co-founders Ansel Mullins and Yigal Schleifer recently spent a few days introducing a crew from the CBS Sunday Morning show to Istanbul’s gastronomic underbelly, at one point journeying in a rickety wooden boat on the Golden Horn in order to get to the next meal.

Certain global phenomena, like sushi, the mojito and the sitcom Golden Girls, might have arrived a bit late in Turkey, but as the world scrambles to go local, eat seasonally and connect with traditional culinary roots, Turkey is way ahead of the pack. Gram, chef Didem Şenol’s carefully curated locavore deli in Şişhane, feels perfectly in step with the stripped- down style that chefs from New York to New Zealand are favoring today.

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.

Turkish politics make for a great lunch counter conversation. These days, one of the hot topics is a perceived axis shift, as if Ankara, feeling burned by the West, has turned the gaze of the Republic eastward, as easily as a dönerci reverses the rotation of his spit. But down in Karaköy at NATO Lokantası, an esnaf lokantası named in honor of Turkey’s entry into the Western Bloc some six decades ago, the tenor of the debate is still decidedly Cold War-era.

We’ve previously extolled the pleasures of Cretan cuisine at Athens venues like Kriti and noted that Crete has one of the highest life expectancies in Greece, thanks in part to its healthy food. So we were particularly intrigued by “The Island Where People Forget to Die,” a recent New York Times Magazine article on Ikaria, a Greek island in the Aegean that’s home to some of the world’s longest-living people.

There are places that have been around so long that they've become emblematic of a city’s entire eating culture. In Athens, Stani (meaning "sheepfold" or "barnyard," depending on your definition) is certainly one of them. It may have a rustic-sounding name, but this wonderful, old-fashioned dairy bar – in business since 1931 – is an urban fixture.
