Deservedly famous for its rich food traditions, the state of Oaxaca is one of our favorite culinary destinations in Mexico. But with Oaxaca City lying nearly 300 miles southeast of Mexico City, we’re always on the lookout for places to satisfy our appetite for Oaxacan cuisine in the D.F. Specializing in tlayudas, one of Oaxaca’s most typical foods, the recently opened Aguamiel is a very welcome addition to the local dining scene.

A bodega can be a corner store or a corner bar, or sometimes even a wine cellar with a small kitchen serving refined riffs on traditional Spanish foods. In Barcelona, a bodega is all of these, but most of all it is the beating heart of the neighborhood.

QUICK BITE: Spend the day eating your way through Sants, a lesser-explored neighborhood with a booming local food scene and an interesting history. We’ll dig into markets and old vermuteria, pastry shops and down home restaurants, but we’ll also find the pulse of Sants in some contemporary culinary projects.

Lisbon seems to be getting its groove back. Or at least, more people are taking notice of this city’s unique character and clearly taking to it. Recently, Vogue and The New York Times profiled the Intendente district, an up-and-coming neighborhood in the city center; Monocle magazine held its first “Quality of Life” conference in Lisbon; and many friends of ours, from Istanbul to San Francisco, are sharing beautiful photos of their latest trip to the city. Oddly, in a city on the upswing with such a rich culinary heritage, we found there was little storytelling on the subject of food and how it impacts Lisbon’s urban culture, be it in print, on the Web or on the ground (as in a tour or other guided experience).

In the era of such food crazes as the “cronut,” it seems that every city has its own classic fried-dough treat that is now being reimagined, and in Athens, loukoumades (think of them as the Greek predecessor of doughnut holes) seem to be getting a major overhaul as of late. Why revamp such a perfect childhood classic, you might ask? Loukoumades are considered to be one of the oldest recorded pastries (and desserts, for that matter) in the world – in fact, the ancient Greek poet Callimachus and philosopher Aristotle wrote about these bite-sized, fluffy fried-dough balls. The triumphant winners of the first Olympic games in ancient Greece were the ceremonious recipients of xarisioi plakoi (χαρίσιοι πλάκοι), or honey gift-cakes.

Tbilisi’s Vake Park district is an upscale neighborhood full of designer cafés and fancy-looking Georgian-European restaurants offering mediocre grub at prices that complement the black SUVs and silver Mercedes that crowd the streets. Sure, you can find a good place that serves up the typical tasty Georgian menu at a fair price. But for original Georgian cooking with particular attention to fresh ingredients and the process of putting them together so that all the individual flavors explode in your mouth, look no further than Citron Plus.

Up in the high streets of the Horta-Guinardó hills, not far from the old historic building of L’Hospital de La Santa Creu i Sant Pau, there is a restaurant with a big concentration of culinary talent but just eight tables. To make things worse, they are only available during two hours for lunch. Fortunately for those who can’t snag one of those precious tables, La Cuina del Guinardó (“Guinardo’s Kitchen”), a Catalan traditional market-cuisine restaurant, is also a store selling cooked food to take away from morning to evening and a great wine shop, with a tasting area in the upper level.

Settled by Greek refugees from Turkey after 1923, Nea Erythraia is a northern suburb of Athens that started off very low-key and has now evolved into a buzzing shopping and nightlife area, full of cafés, bars, restaurants and gelaterias. Despite the recent boom, many places that have been local favorites for over a decade now are still popular. One such venue, a small, unassuming restaurant with the welcoming name of “Kali Parea” (meaning “good company” in English), is hidden in a quiet street off the main road. Its faithful clientele come here to savor seasonal fish (mainly small fry) and seafood (calamari, octopus and shrimp), prepared either fried or grilled.

Bāozi (包子), or steamed buns, are a basic, on-the-go meal. It’s rare to come across a shop selling these buns for more than 1.5 RMB (US$0.25), and yet, the past five years have seen a dramatic rise in the stature of this humble dish – thanks mostly to celebrity chef David Chang, whose Momofuku pork bun has become world-famous. They even got a domestic boost in 2013, when President Xi Jinping visited a local 60-year-old baozi shop in Beijing. (Now, thanks to an hours-long queue to try the “President Special,” that chain is looking to go public.) Legend has it that baozi date back to the Three Kingdoms period (A.D. 220-280) and are credited to Zhuge Liang, a renowned military strategist who was also an eccentric foodie. He invented both this steamed bun and our favorite breakfast treat: the jianbing

Though Brazil is rich in mother earth’s most colorful produce – like passion fruit, guava, papaya, collard greens and sweet abóbora pumpkins – residents of Rio nonetheless have a steady love affair with hot dogs, which are pronounced “HOH-tchee DOH-geey,” or literally translated into Portuguese as cachorro quente. Vendors across the city pile the bunned favorite with a set of toppings as elaborate as they are consistent from one cart to the next: hard-boiled quail eggs, green peas, corn, potato straws, stewed onions and Parmesan cheese. “Tia” was a young mother of three with a husband whose blue-collar salary as a cop meant life was a hustle in their working-class neighborhood of Freguesia. “I had to take them all to school, prepare breakfast, the school uniforms,” she said. “I got no rest.” Her hot dog vendor days began in 1982, when her daughter was a newborn, and she had what she now says were two decades of busting her chops before the cachorro quente da Tia would become one of the most in-demand snacks in this periphery neighborhood of Rio. “Thank God,” she says of her success in her hot dog business, which now encompasses both a quiosque and a store, with 16 employees in total.

Metin Akdemir is a filmmaker based in Istanbul. In 2011 he made a short film about street vendors in the city. The film, “Ben Geldim Gidiyorum” (“I’ve Come and I’m Gone”), won several awards in Turkish and international film festivals, and we think it’s a very valuable piece of work that captures a side of Istanbul’s culture that is slowly disappearing.

As the towers of Tokyo’s Nihonbashi financial district began to proliferate and grow taller, developers took special care to preserve and in many cases not displace the area’s mainstream department stores, art galleries and varied restaurants, and so traditional establishments were often incorporated into the new buildings. The Mitsui real estate group, which opened the two Coredo Towers in 2014, made sure to include time-honored restaurants in the new setting, including an amazingly good, classic Edo-mae sushi bar lured from an outdated setting, an outpost of a Kyoto home-cooking restaurant and a dazzling array of famous sweets shops. The developers were also clever enough to include a classic izakaya, or pub-style establishment, enticed away from the Tsukiji market. Every evening, office workers pour out of local mega-buildings and pack into Nihonbashi Suminoe to enjoy the collegial atmosphere and flavorful charcoal-cooked fish. Sakaya means a location in which to purchase sake, and “i” means to stay in a place and feel at ease. Thus, i-sakaya becomes “izakaya” when pronounced correctly, and it’s the perfect way to describe Nihonbashi Suminoe.

When we picked up a cab from Meşhur Unkapanı İMÇ Pilavcısı recently, it turned out the driver had just been there for a refuel himself. Sensing a captive yet interested audience, he held forth all the way to Beyoğlu about where to eat well and cheaply – without stomachaches ensuing – in Istanbul. We’re always happy to discuss the finer points of kuru fasulye (stewed beans), but this driver seemed to have a particularly deep interest in the subject. After debating the merits of various canned brands (“Yurt” brand or nothing, in case you were interested), he dived into the subject of soup.

It might sounds sacrilegious, but when we’re in Berlin, döner isn’t our go-to street sandwich. Though it is widely believed that the German capital is the birthplace of the beloved sandwich, that fact alone does not provide citywide quality assurance. The rapid ascension of the döner sandwich as the city’s eminent fast-food staple has unfortunately resulted in its mass production, which means one is likely to encounter a nondescript rotating wheel of frozen mystery meat. This isn’t to say that excellent yaprak döner (a carefully crafted cylinder consisting of freshly layered cuts) cannot be found in Berlin. But the way the sandwich is dressed in this city – with a variety of vegetables, sauces, cheese and fresh-squeezed lemon or lime – is indeed conducive to covering up the taste of boring meat.

Editor's note: Our recurring feature, Building Blocks, focuses on foods and ingredients that are fundamental to the cuisines we write about. This may come as a surprise, but little Greece is Europe’s fourth most important honey producer after Spain, Germany and Hungary. Every year, between 12,000 and 17,000 tons of this liquid gold are stolen from the country’s roughly 1.5 million hives and poured into jars to satisfy the local desire for honey. And it seems Greeks can’t get enough of it. They rank high among the world’s consumers, slurping up 1.7 kg per person every year as they use it to sweeten tea, drizzle over yogurt, slather on toast and soak baklava and other desserts. By contrast, the average American ingests a mere 400 grams.
