Known for its excellent fish and seafood, the port town of Piraeus, just west of Athens, was not until recently a destination for meat lovers. But that all changed a year ago with the opening of Bar Bee Kiou. Situated in the center of town, a two-minute walk from Zea Harbor, this tiny eatery is the ideal place to cap off a promenade around picturesque Pasalimani.

Dear Culinary Backstreets,We are traveling with a group of friends to Barcelona. A few of us are vegetarians, and we all love good food. I know Barcelona is a meat – and particularly pork – lover’s paradise, but can you recommend any vegetarian-friendly restaurants? Is it possible to enjoy tapas and Spanish cuisine without meat or fish?

As the moon starts to wane each January, people throughout China frantically snatch up train and bus tickets, eager to start the return journey to their hometown to celebrate the Lunar New Year (春节, chūnjié) with their family. This year, revelers will make an estimated 3.64 billion passenger trips during the festive season, up 200 million from the previous year. One of the major draws for migrant workers heading home is the chance to eat traditional, home-cooked meals.

Fried tortillas, stuffed and sauced: enchiladas are simple in concept, but they come in a seemingly endless variety, depending on region and ingredients. The tortillas might be made of corn or wheat flour, and they could be stuffed with all manner of meat or vegetables (or both), but the sauce – or salsa – is really what it all comes down to.

“I’m not a missionary, but I am not doing this just to make a profit. People must see that there is mantı outside of Kayseri, there’s Crimean Tatar mantı, as well,” explained Gülben Resuloğlu, in front of her restaurant in the leafy Feneryolu district of Istanbul’s Asian Side.If Martha Stewart were in the mantı (also known as “Turkish ravioli”) business, her place would look just like Gülbi’s – meticulously decorated in pastels, white and floral prints. Everything matched, even the two neatly dressed women who welcomed us: Gülben (the Gülbi in question) and her sister, Leyla. But kept just behind tidy appearances, we discovered, is the pain of being Tatar. We’re convinced that this identity, which was forged in the fire of dispersal and diaspora, made the food taste better.

Editor’s note: We regret to report that La Portería has closed. Looks can be deceiving. A case in point: La Portería appears dull at first glance, but venture down the few steps that separate this singular restaurant from the street’s frivolity and you will be rewarded.

It’s been more than half a century now since The Beatles formed, and their worldwide popularity continues unabated. In Japan especially, the band’s presence and influence were outsized almost from the beginning, and John Lennon’s marriage to Yoko Ono cemented the band’s place in Japanese culture.

In a country the size of Brazil, you’ll have an easier time finding a carioca who’s been to Disney World than to the Amazon region, so cut off is it by vast forests and pricey airfares from the cosmopolitan southeastern cities of São Paulo and Rio. When we visited Manaus and took a days-long boat trip on the Rio Solimões, we introduced ourselves as American, living in Rio. Locals seemed uninterested in asking the usual litany of questions about America but grilled us on Rio, which they had only seen in evening telenovelas.

Editor's note: Our last dispatch for Breakfast Week takes us to a charming spot in Beyoğlu, where followers of Istanbul's two competing schools of breakfast can enjoy their morning meals side by side. Istanbul is a dynamic city, where conditions can change so quickly and completely that it’s easy to forget the way things used to be. The new reality can be so strong and ever-present that the past feels like a hazy dream, if that. But no, this is not an article about Turkish politics. This is an article about Turkish breakfast.

Fried pig’s ears fortified with garlic and parsley, veal cheek and tongue laced with vinaigrette, hefty veal and pork meatballs, creamy artichoke or eggplant omelets or a hearty bocadillo of marinated tuna, red pepper, anchovies and olives: these esmorzars de forquilla, or “fork breakfasts,” are how a Catalonian might start his day – especially at Can Ros, a tapas-and-bocadillos joint that’s open every day from 7 a.m. until midnight. Office workers might drop by for a coffee at mid-morning, followed by the lunch crowd, which takes over from 2 p.m. to 4 p.m. Dinner, of course, lasts well into the night. It’s breakfast, however, that has made Can Ros most popular among locals.

Editor's note: We are regret to report that Nixon and Hip Cafe are closed. Editor's note: Our third installment for CB's Breakfast Week takes us to Athens, where we take a look at traditional breakfasts and how globalization is changing the way Greeks eat -- especially on weekend mornings. In Athens, brunch has become big business. Over the last couple of years, locals have fully embraced this foreign import, and numerous venues have sprung up across the city to bring Eggs Benedict and Bloody Marys to hungry Athenians every weekend.

Editor's note: It's Breakfast Week at CB, and the second piece in the series takes us to Mexico City for a look at typical morning meals and the best places to find them. Stay tuned for more breakfast dispatches from other CB cities throughout the week. Mexico leads the world in per capita egg consumption, according to the country’s National Poultry Institute. That’s not hard to believe if you’ve ever taken a look at a typical Mexican breakfast; in homes and at restaurants huevos are the first order of the day for many a desayuno. And with all those eggs they eat, Mexicans have come up with a number of ways to dress them up or down. One of the most popular ways to prepare them, for example, is huevos revueltos al gusto, two or three scrambled eggs with an additional ingredient or ingredients, such as ham, chorizo, sausage, vegetables or a la mexicana (onion, chilis and tomato). Huevos can also come divorciados, which are two sunny-side-up eggs, one bathed in green salsa and the other in red; rancheros, or fried and served over corn tortillas and refried beans and bathed in a red or green salsa; al albañil, scrambled and served with a very hot red salsa and fresh cheese; or ahogados, poached in green or red salsa. Most of these egg dishes are served with a side of refried beans, avocado and corn tortillas.

Editor's note: It's Breakfast Week here at CB, and to kick off the series, we first head to a street corner in the heart of Shanghai that offers a remarkable variety of breakfast foods. Stay tuned all this week for more morning dispatches from other CB cities. We’re all guilty of indulging in the complimentary hotel breakfast buffet a little too often while traveling. But in Shanghai, the widest array of street food is on full display in the morning hours, as young professionals and retirees alike gather at their favorite stands for a quick bite with friends or on their way to work.

In a city filled with Technicolor snack bars, Casa Paladino Comestíveis instead looks more like the kind of place where you’d find seedy men smoking cigars in a black-and-white film. Glass cases lining the walls display manila-labeled cachaça and Cuban rum bottles, with an occasional anachronism, like boxed Toddynho chocolate milk, breaking its turn-of-the-century salon aesthetic. Cloudy mirrors, a handwritten menu and a grape-adorned Bacchus sculpture decorate its black carved wooden walls.

Just a stone’s throw from centrally located Vasileos Konstantinou Avenue, the tree-lined neighborhood in and around Plateia Proskopon (Scouts’ Square) is verdant and full of charm. Wonderful dining options abound here, with new entrants such as the popular Mavro Provato joining a host of beloved older eateries. Among the latter is Magemenos Avlos, a glamorous throwback specializing since 1961 in European cooking, and a favorite meeting place of musicians, poets, actors, politicians and remarkable personalities of the 1960s and ’70s.
