Piraeus holds the distinction of being Greece’s biggest port, as well as the largest passenger port in Europe. Although it is a mere 20-minute train ride from downtown Athens, most Athenians think of Piraeus with a reverence reserved for a foreign country. There is just something almost mythic about this ancient port, which has been in existence since the 5th century B.C. – the famous opening line of Plato’s Republic is, after all, “I went down to the Piraeus yesterday.” In the modern period, the greater Piraeus area – home to a population of about half a million in Piraeus proper, along with a number of suburbs – has witnessed dizzying highs and lows, especially over the past century. The area has been a major destination for immigrants from elsewhere in Greece, including the islands and the Peloponnese. One of the biggest population expansions came after 1922, when vast numbers of Greek refugees fleeing Asia Minor (modern-day Turkey) migrated to the area and established new working-class neighborhoods, including Nikaia, Keratsini, Drapetsona and Korydallos.

Most people who visit Barcelona are sure to spend at least some time at one of the city’s beaches. Yet few are aware that when seeking respite from the bustling urban streets, heading up into the forested hills above the city can be just as pleasant. Vallvidrera, a village at the entrance to Collserola National Park that offers gorgeous views of the surrounding forests and the city below, is just the place for such an excursion. Starting in the early 19th century and up until the 1980s, Vallvidrera served as a vacation destination for wealthy Barcelonans who wanted to escape the summertime heat of the city. The abundance of mansions here, many built in the Modernist style, is a testament to this bygone era. Nowadays, although Vallvidrera is a year-round community that is technically part of Barcelona proper, it’s still a destination for local urbanites and their families wanting to get out of the city and relax, particularly on weekends.

Editor’s note: This feature, by guest contributor Gizelle Lau – a Chinese-Canadian food and travel writer based in Toronto – is the first in an occasional series on “diaspora dining,” covering the best places to find our favorite cuisines outside of their places of origin. The history of Chinese in Canada – pioneers who left their native land in pursuit of a better life and future – is a familiar immigrant story.While the first record of Chinese in Canada dates back to the late 1700s, it wasn’t until the late 1800s and early 1900s that they began to arrive in greater numbers, establishing Chinatowns in cities such as Toronto and Vancouver and opening their own restaurants, grocery stores and laundromats. Despite exclusionary government policies that existed for many years, today Canada is home to one of the largest Asian populations outside of Asia, including over half a million Chinese in the Greater Toronto Area alone.

Dear Culinary Backstreets, I keep hearing about the wonders of Cretan cuisine, but is it really any different from regular Greek cooking? And is there anywhere nice to try it in Athens?

Editor’s note: This is the second piece in our series featuring the hidden gems in some of Athens’ most touristy neighborhoods. We previously explored Psyri; it is now time to take on the holy grail of Athenian tourism: Plaka. There’s a reason why this area of old Athens, just below the Acropolis, is the city’s most touristy neighborhood: it has a history of more than 6,000 years.

With the brutally forceful clearing of Gezi Park of its temporary inhabitants by Turkish police, the recent protests in Istanbul have lost the imposing physical presence that, incredibly, lasted for two weeks. These days, protestors are tossing ideas onto social media walls to see what might stick. To keep the resistance alive, we’ve been urged, via Facebook, to take part in all sorts of acts, passive and active, madcap and practical. But the one that really struck a chord with us is a campaign not to spend any money in shopping malls, not to even enter shopping malls, and to spend only what we must at small, local shops. Boycott the mall? Now, that’s a battle we’ve been waging since the late 1980s.

It’s not every day that you find a former national volleyball champ in the kitchen, but that’s just the case with Lu Dajie (aka “Big Sister” Lu) and her eponymous restaurants. After a successful career with the Chinese military’s volleyball team, followed by years working in restaurants for others, she left her hometown of Jianyang in Sichuan province with her brother, bringing her region’s famous cuisine with her. Now, in Shanghai, she is slowly building an empire.

Dear Culinary Backstreets, Where can I go in Barcelona when I'm tired of sightseeing and I just want to sit down and relax with a cup of coffee? Visiting museums and landmarks can be a lot of fun when you're a tourist but sometimes you can learn more about the life of a city by sitting in a chair in a café than you can by reading any guidebook. In Barcelona, there's no shortage of cafés but like anywhere else, it can sometimes be a bit tricky to find one that has just the right ambiance.

Editor’s note: This week we are celebrating street food, in all its fascinating, delicious and sometimes offbeat forms. Each day, we’ll take a look at the top street foods in a different city that Culinary Backstreets covers. This feature from Shanghai is the first installment. 1: Shengjianbao A Shanghai specialty, shēngjiān mántou (生煎馒头) – or shēngjiān bāo (生煎包), as they’re known everywhere else in China – are juicy pork buns wrapped in bread dough, then arranged in a flat, oil-slicked wok in which the bottoms are deep-fried till they are crispy. Although shengjian mantou can be found on most street corners in the morning, we’re especially fond of the delicious misshapen buns at Da Hu Chun. A Chinese Time-Honored Brand (老字号, lǎozìhào), Da Hu Chun has been splattering grease since the 1930s and, nearly 80 years later, has six restaurants across Shanghai. The venue’s chefs use the rare “clear water” technique, frying the pinched side of the dough face-up to create little Frankenstein buns that might not be as photogenic as the more common “troubled water” variety, but that have a thinner skin that gets extra crisp – and we’ll sacrifice good looks any day if it means better flavor.

Dear Culinary Backstreets, My husband and I are planning a visit to Istanbul with two little ones in tow. We love to be adventurous with food and want to explore the city’s culinary scene, but are also a bit concerned about finding “child-friendly” places to eat. Do you have any recommendations?

In 2008, Shanghai’s noodle scene was dealt a mighty blow. A Niang, a granny from the ancient seaport of Ningbo who was famous among local foodies for her seafood noodles, was forced to close her streetside shop after being diagnosed with kidney disease. Over the past few decades, she’d gained a loyal following; her friendly, wrinkled face was a common sight in the dining room, as she often wandered through the hordes of hungry diners to say hello to regulars or wipe up a splash of spilled soup.

Considering Athens’ position as a top tourist destination, it may come as a surprise that it is only recently that local museums have decided to up their game when it comes to their dining offerings. Worldwide, a good restaurant and café are now considered part of the whole museum-going experience, but it took a little time for Athenian museums to catch on to that, though catch on they have.

On the diner intimidation scale, Shanghai’s Chenghuang Miao Tese Xiaochi – which can be loosely translated as “City God Temple Snack Shop” – ranks pretty high, with aggressive lunchtime crowds and nothing but Chinese character-laden menus for guidance. But the payoff, a baptism by fire in authentic Chinese eating, is worth it. The hungry masses that congregate here have discovered a simple truth: the food here is quick, tasty and cheap – a gastronaut’s holy trinity.

Dear Culinary Backstreets, We will be visiting Barcelona with our children. Do you have any good recommendations of places in the city to eat with kids?

While the Princes’ Islands make for a great escape from the city, it used to be hard to think of them as a culinary destination. That is, until Heyamola Ada Lokantası opened. The restaurant is a perfect storm of inspired food, chill ambiance and small-label Turkish wines, all at ridiculously low prices.
