One of China’s most ubiquitous culinary exports, Sichuan cuisine is famous for the 麻辣, or málà (mouth-numbing spice), that comes in the form of a peppercorn (花椒, huā jiāo). Prompting a tingling sensation that has been likened to licking a nine-volt battery, the lemony husk is tossed into dishes with dried chili peppers, and never more skillfully than at Yu Xin.

Inside Fatih Karadeniz Pidecisi, nothing could be heard over the crunch and crackle of fresh pide being torn open and chomped down on. Still, the man across the table from us spoke in a low, conspiratorial whisper: “There are some very well-known businessmen sitting at that table by the window. They all come here,” he said.

Colibri constitutes something of an Athenian phenomenon: what started out as a small neighborhood pizza and burger takeout place in Mets, next to Athens’ grand First Cemetery, has now evolved into three successful restaurants where people actually queue for more than half an hour to eat homemade pizzas and burgers. The menu is the same in all three places, offering simple comfort food at decent prices.

The so-called “ethnic” cuisines – from Middle Eastern and Indian to Chinese and Japanese – came to Athens relatively late, in the mid-1980s, and were a costly affair. Athens’ first “exotic” restaurant, the Kona Kai in the Athens Ledra Mariott Hotel, opened its doors in 1984 and was one of the city’s most fashionable, high-class restaurants for years, serving Polynesian cuisine. It remains untouched, at least in terms of décor: the venue is a glorious extravaganza of bamboo and waterfalls!

Peynir means cheese in Turkish and peinirli (derived from the Turkish word peynirli, meaning “with cheese”) is a delicacy adored by pretty much everyone in Greece that strongly resembles the Turkish pide. It is a boat-shaped bread that is high in yeast and butter, with a buttery, cheesy filling.

Housed in a bright pink neoclassical-style building on bustling Praxitelous Street (a road full of shops selling electrical equipment, wholesale beads and jewelry supplies), Doris has been around since 1900. It’s a traditional Athenian eatery known as a mageireio, which roughly means “cooking house” or “eating place.”

Any Shanghai denizen who has lived in the city for longer than a few months worships at the altar of xiǎolóngbāo (小笼包). These steamed buns of goodness – tiny pork dumplings with a slurp of soup wrapped up in a wonton wrapper – provide delicious fodder for debates among Shanghai’s fiercest foodies.

Viena is the love child of an Austrian ski lodge and a McDonald’s. This Catalan fast-food joint – which has become an obligatory foodie stop thanks to New York Times food writer Mark Bittman, who famously wrote that Viena’s flauta de jamón ibérico was the best sandwich he’d ever had – dishes up fast and delicious grub with a side of kitsch.

We’re especially fond of Istanbul’s vibrant – and sometimes plain wacky – street food scene. Here we present three of our favorite street foods and the best places in the city to get them.

For a Chinese city as fast-paced and increasingly cosmopolitan as Shanghai, there are surprisingly few late-night dining options that don’t involve ordering from the roving, streetside pushcarts that hawk grilled skewers or fried rice and noodles. Unfortunately, these midnight vendors are not always where you want them to be when you need them most, after 10 beers. Enter Ding Te Le.

In a city that stays up as late as Athens, it’s no surprise that late dinners and even later-night snacking are big. People don’t go out to dinner before 9 p.m., and most restaurants serve food up until midnight every night. Plenty of places are up and running till the early hours, or even all night long.

Hong Kong native and Cha’s owner Charlie Lau became a restaurateur because of a hankering. A movie producer by day, Lau came to Shanghai with Ang Lee to film “Lust/Caution,” and was disappointed that Shanghai lacked a proper Hong Kongese cha canting, a casual all-day eatery that serves traditional Cantonese food alongside milk teas and coffee. So he decided to open his own. On the set of “Lust,” a 1930s period piece, Lau was responsible for ensuring the historical accuracy of the costumes, casting and set design, so it’s not surprising that he designed Cha’s with the past in mind. Walking across the restaurant’s threshold transports you to 1950s Hong Kong.

In the evolutionary process of the Istanbul fish restaurant, there was a moment in the late 1990s when the amphibious, shore-hugging boat restaurants crawled out of the Bosphorus and became land dwellers. Overnight, yellow Wellington boots became black loafers as seafaring grill men became restaurateurs and waiters.

Beyond the kebab – and what you will find listed in most guidebooks for Istanbul – lies a wide range of unique Turkish regional cuisines and restaurants with hints of Balkan, Caucasian and Middle Eastern cooking. The city has been a crossroads of numerous civilizations for centuries and, more recently, a magnet for migrants from across Turkey, with every group that has either come through or stayed put adding their ingredients to Istanbul’s culinary stew. Thanks to this, one of the joys of visiting Istanbul is that, in terms of eating, it’s possible to visit every one of Turkey’s varied regions – and even a few neighboring countries – without ever leaving the city limits. With restaurants serving everything from the Middle Eastern-influenced kebabs of Southeast Turkey to the homey, rib-sticking soul food of the Black Sea area in the North, Istanbul has truly become the culinary Babel of the country.

Dining like a local in Shanghai often requires a small leap of faith. You have to forget about ambience and brave tough crowds with even tougher elbows to join the raucous, slurping masses with their steamers of the city’s famous soup dumplings, xiǎolóngbāo. Even with its thriving economy and sky-high construction boom, Shanghai still has a street food culture that is deliciously cheap and easy to find. To become a part of the appetizing fun, just look one street off the main road or wander into the city’s disappearing lilong (里弄, alleyways), which more often than not are teeming with Chinese pancake hawkers, wonton shops or makeshift grills emitting the smoky aroma of charred lamb kebabs.
