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.

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.
