One of the things we love about Japanese food is that it celebrates specialists. A good sushi chef makes only sushi, and only after years of study to learn the art of making the perfect rice. Likewise, only a master of the dynamics of hot oil can craft perfect tempura. So it’s no surprise that at Japanese chicken restaurants one can find a true dedication to specific methods of preparing fowl.

We hear it every time we bring up the V-word: “But it’s impossible to be a vegetarian in Rio!” Nonsense. Not only is it possible to eat an earthy diet here in Rio, it’s getting so trendy that carnivorous cariocas are increasingly forgoing their weekend churrasco (grilled meat on a stick) for the kaleidoscope of couve (collard greens), cogumelos (mushrooms), tofu and all of its soy brethren. While Rio de Janeiro’s vegetarian options are often lunch-only buffet-style joints (and we like those too), we’ve been intrigued by the rise of a few more boutique à la carte places. And we appreciate that Prana Cozinha Vegetariana is one of those that does not come with boutique prices.

In September of last year, Shanghai eaters were shocked when Mr. Wu shuttered A Da Cong You Bing, the city’s best scallion pancake shop. The only explanation for the abrupt closure was a worn sign on the door that read: “My family has a problem. The stall will be closed for a few days.” But this wasn’t the whole truth. Some attributed the shutdown to the fact that the stall was featured on the BBC program Rick Stein’s Taste of Shanghai, claiming that it had drawn too much attention to the unlicensed vendor and the government had taken note.

It all started with a seriously delicious hamburger in New York City. Rumor has it that it was this burger that first gave acclaimed Catalan chef Oriol Rovira the idea of opening Sagàs Pagesos y Cuiners (“Farmers and Cooks”) in the Born district of Barcelona. Specializing in high-end sandwiches, the restaurant embraces the farm-to-table philosophy, with a menu that is both distinctively Catalan and international in scope. Rovira, who also runs Els Casals, a Michelin-starred restaurant in the tiny village of Sagàs near the edge of the Pyrenees, opened his sandwich spot in May 2011. As at Els Casals, nearly all of the food at the Barcelona venue comes straight from the chef’s village farm. But why sandwiches?

(Editor's Note: In honor of the immigrants and refugees who have made their new home a better place for us all, this week we are running some of our favorite archived stories about those who have left a culinary mark on their adopted land.) "Despite the fact the Armenian quarter of Athens had been created out of the rubbish heap there was more charm and character to this little village than one usually finds in a modern city… In the midst of the most terrible poverty and suffering there nevertheless emanated a glow which was holy; the surprise of finding a cow or a sheep in the same room with a mother and a child gave way instantly to a feeling of reverence." This is Henry Miller’s description of Neos Kosmos in his 1941 travelogue, The Colossus of Maroussi. Known then as Dourgouti, Neos Kosmos (Greek for “New World”) was one of the shantytowns that had sprung up near the center of Athens housing the thousands of Anatolian Christians who had fled from Asia Minor after the Greco-Turkish War (1919-1922).

(Editor's Note: In honor of the immigrants and refugees who have made their new home a better place for us all, this week we are running some of our favorite archived stories about those who have left a culinary mark on their adopted land.) Although we’re always hitting the pavement in search of the next good place to eat, sometimes places come to us. Such was the case with Tacos Árabes La Periquita, or “The Little Parrot,” an unassuming taquería in San Rafael that serves a relative rarity in Mexico City: “Arab tacos.”

Despite the 1970s-era sign outside that says Granja (farm) and the red letters spelling “Bar” inside, you can’t really tell what this place is until you open the menu: a temple of “neighborhood haute-cuisine.” The food at Granja Elena sounds simple but tastes rich and complex. The restaurant is a family business, now run by the third generation – Borja, Patricia and Guillermo Sierra Calvo – in the same barrio in which it was founded in 1974, La Marina del Port. This modern neighborhood is part residential and part industrial, a bit far from Barcelona’s center, located near the merchant port behind Montjuic and on the way to the airport.

From the street, Café Lamas looks almost intentionally nondescript. A fluorescent-lit bar with a glass case of snacks and a few metal chairs would make it identical to any other lanchonete (snack bar) across the city, if it weren’t for the shadowy doorway behind the bar’s aisle. Behind that door awaits a blast from the past. Café Lamas is Rio de Janeiro’s oldest restaurant – a respectable 138 years old in a city that is rapidly putting on a new face as it buzzes with Olympic, hotel and condominium construction – and the place radiates a sense of history and tradition. Bow-tied waiters politely bend as guests enter the dining room, which is dimly illuminated by lamps on ornate cast-iron mounts.

The era of Portugal’s seafaring might was so long ago, it seems almost like a myth – one still patriotically related by locals today. Gastronomic evidence of the country’s imperial past remains, however, particularly in Lisbon, where Angolan, Brazilian and Goan eateries can be found among the many other restaurants serving non-Portuguese food. Yet, despite Macau being under Portuguese control for around four centuries, passing into Chinese administration only in 1999, Macanese cuisine is still a mystery. Lisbon has yet to see even one Macanese restaurant open. There is a place here, however, to eat food from Macau: a cultural association in between Alvalade and Areeiro on a main road that leads to the airport, far from Lisbon’s center.

Cyprus’s tavernas are famous for flame-grilled meat, fish and halloumi cheese, but go to an islander’s home and you’re much more likely to find a pot of something slow-cooked simmering on the stove. Mageireia are traditional Cypriot restaurants serving this comfort food at reasonable prices. We think Mattheos, a tiny family-run lunch place located behind the Faneromenis Church and beside a disused mosque in Old Nicosia’s most picturesque square, is one of the best.

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.

Dear Culinary Backstreets, I’ve heard about “wet markets,” but what are they exactly? And where can I find the best wet markets in Shanghai? Stocked with all the fresh produce and live seafood that hungry Shanghai residents could ever cook up, wet markets are an essential alternative to the brand-name supermarkets vying for their slice of the market share of the planet’s largest population. These markets are so named because the floor tends to be wet, thanks to the live fish flopping around and the vendors’ habit of throwing water on the ground to keep the area clean. They are, however, under constant pressure from the central government’s drive to urbanize the population and modernize facilities, which has led to the steady destruction of the more traditional ones.

Tacos are everywhere in Mexico City, and though the options are many – chicken, al pastor, carnitas, carne asada – the basic ingredients tend to be the same wherever you go. That’s why, as we were walking the aisles of Tianguis La Raza on a Sunday morning, El Parrillón caught our attention. A big sign announced tacos – nothing new there – but besides the classic chicken and bistec, cecina and arrachera – all different cuts of beef – El Parrillón (roughly, “The Big Grill”) offers several Argentine-style sausages and cured meats, including chistorra, a small spicy sausage, and panceta, pork belly (like Italian pancetta), as well as Spanish chorizo, which, unlike the fresh Mexican sausage, is cured. But for us the real draw was griddled provolone, which we had never seen on a taco before and happens also to be one of our favorite cheeses.

On a beautiful corner of L’Eixample sits Norte, a small yet warm, inviting and light-filled bar with a constellation of shining lights spelling out its name inside and a few tables with fresh flowers. The restaurant was started by three partners, Lara Zaballa, María González and Fernando Martínez-Conde (who left the project last year). They met while working at Barcelona’s acclaimed Moo restaurant and had come to cooking from studying philosophy, art history and journalism at university. They were each looking for something more hands-on, work that gave them direct physical contact with matter, and that shared motivation connected them from the beginning. All three also came to Barcelona from other cities in northern Spain. After their experience at Moo and other projects (Zaballa and Martínez-Conde wrote for the prestigious cooking magazine Apicius), they looked for a more enjoyable and less stressful way to do what they loved, starting with basically nothing but their enthusiasm and their solid ideas to convince the banks to give them a loan to start their own restaurant in 2011.

Mexican cooking is clever. With just a handful of ingredients, each region of the country has managed to create a unique cuisine that reflects local lifestyles and traditions. This fact is made abundantly and deliciously clear at Con Sabor a Tixtla, a small, family-owned restaurant in Mexico City’s hip, vibrant Roma neighborhood. Located on a quiet street not far from Mercado Medellín, the restaurant specializes in food from Guerrero, a southwestern state – home to the famous resort town of Acapulco – known for its seafood and its green pozole, a meat and hominy stew that is one of Mexico’s most iconic dishes.
