Way south of the pure, unadulterated hustle and bustle of the historic center, east of refined and residential San Ángel, and northwest of Xochimilco and its colorful canals lies Coyoacán, a neighborhood unlike any other in the megalopolis that is Mexico City. Once an artsy hangout for the movers and shakers of the day, like Frida Kahlo and her husband Diego Rivera, as well as a refuge for exiled Communists like Leon Trotsky (all three have house museums dedicated to their honor in the barrio), Coyoacán is now a popular tourist hangout. However, you don’t have to scratch far beneath the surface to find remnants of Coyoacán’s traditional, if somewhat romanticized, past.

Around 30 people crowd into a small bar in a quiet neighborhood in Lisbon for a film screening. It’s a Wednesday night, but the place, called Valsa, is full, despite the fact that it’s in a peripheral residential zone. “Valsa” is the Brazilian translation of “waltz”; the Mittel-European folk dance that arrived to Brazil via Portugal in 1808. Danced in the elite salões of Rio de Janeiro, the term is now back on this side of the Atlantic, thanks to this tiny Brazilian-run association with one of the busiest cultural programs in the city.

“The future is the past,” says Salva Serra, quoting winemaker Pepe Raventós, the latest in a long line of winemakers to run the famed Raventós i Blanc. While his lineage might not be quite as storied, Salva knows a thing or two about preserving the past – the Serra family has owned La Perla BCN, a restaurant located in the upper Poble Sec neighborhood, very close to Montjuïc Park, since 1965. It’s the type of old traditional restaurant that you only learn about from word of mouth – a friend who only went there because another friend told him about it. The wonderful area where La Perla BCN is situated, with the Poble Sec residential neighborhood on one side and the nearby gardens of Montjuïc hill, home to museums and theaters, including the Grec Theater (built for the Universal Exhibition of 1920), on the other, was not always so charming.

“His name was Mr. Antonio, and they called him the captain,” says 35-year-old Giusy Aiese, launching into the story of La Taverna del Buongustaio. “He was a wine producer from the province of Caserta, and he established a wine-making cellar here in the Fascist period, around 1930.” As we listen to Giusy recount the history of the tavern, we can’t help but think about hers: she comes from a family tree brimming with lovers of Neapolitan cuisine. Her 65-year-old father, Gaetano, a genius in the kitchen, has run La Taverna del Buongustaio since 1996, the year he bought the restaurant from Francesco de Micco, another excellent cook and, funnily enough, Gaetano’s wedding witness.

At the corner of Psaron and Salaminos streets, in a quiet neighborhood of Piraeus, there’s a place that looks straight out of a 1960s Greek black-and-white movie. Its name, eidikon, means “special,” and it’s the last of its kind: a bakalotaverna, or grocery store and eatery, all in one. The shop opened in 1920, when the three Papakonstantinou brothers from Gardiki, an impoverished village near Trikala in central Greece, came to Athens in search of better prospects. The building was the tallest in the area. It had large windows, and in good weather, one could even see the sea on the horizon.

There has always been a bit of a rivalry between the two main cities of Portugal, Lisbon and Porto, which is well illustrated by an old running joke among some tripeiros (the name given to the people of Porto): whenever someone asks what is the best thing about Lisbon they will reply, “The highway sign that says ‘Porto.’” But it’s a healthy rivalry for the most part – football aside. Lisboetas, Lisbon locals, in general even tend to recognize that the food might actually be better in Porto and its surroundings, especially traditional dishes. While Porto does not benefit from the same multicultural influences that helped shape Lisbon’s restaurant scene, it is home to some very talented cooks with a knack for doing so much with so little.

We met Don Tirso in the center of Santa Ana Tlacotenco, one of 12 villages in Milpa Alta, Mexico City’s southernmost delegation, on a sunny and cool morning. The road from village to village in Milpa Alta snakes through fields and around ancient volcanoes, slowly climbing up the mountains that overlook the beast of a city to which it formally belongs. We take a truck to his property, part of a farming cooperative ceded to the campesinos (farmers) following Mexico’s decade-long revolution that ended in 1920, which focused heavily on agrarian reform. In his village, the city’s only rural area covered with forests and farms, his generation of elders is the one that mostly carries the torch of their direct connection to the Aztec past.

It’s the eve of Kurban Bayramı, and while most of Istanbul is eerily empty, the tables at Köklem Uygur Yemekleri in Çapa, a neighborhood in the Fatih district, are quickly filling up. A young couple calmly chats, using chopsticks to pick up sautéed chicken slathered in soy sauce. At a nearby table a man sits alone, his bored countenance swiftly replaced by a broad smile as a waiter arrives at his table with a steaming plate of noodles, ready to be devoured. Most of the customers are speaking a language we can’t decode. But based on how happy everyone looks, this food is bringing them some serious joy.

As the food scene in Barcelona continues to change at a rapid clip, with a constant stream of closings and openings, the city’s bodegas are an excellent example of what can be saved. These are businesses that have been updated again and again, sometimes over the course of a century, in order to preserve an essence and an identity that nobody – not now nor back then – wants to lose. La Moderna, a tapas bar and bulk-wine shop on Carrer d’Enric Granados in the Eixample Esquerra (Left Eixample) neighborhood, is a good example of this preservation model. Established in 1937, the bodega has survived just about everything, including the Spanish Civil War (1936-39).

Last year, Casa de Goa, celebrated its 30th anniversary in Lisbon. Located in Alcântara, it’s a cultural hub for Goans in Lisbon, keeping both traditions and memories alive. Besides a library and museum, there’s a restaurant – currently closed but soon to re-open – and regular events, conferences, exhibitions, games, social gatherings and food workshops. Casa de Goa is particularly active in promoting traditional Goan music and dance: it hosts a folk dance group called Ekvat and the music group Gâmat. Jerónimo Aráujo e Silva is the musical director and also the composer of some of the original songs.

Vasco de Gama’s voyage to India in the late 15th century laid the groundwork for the Portuguese empire, in which Goa, a small region on the southwestern coast of the Indian subcontinent with ample natural harbors and wide rivers, would come to play an important role. In the early 16th century, Goa was made the capital of the Portuguese State of India and remained as such until 1961, when the Indian army captured it. Over four centuries of colonial rule, Goan intellectuals most often migrated to Portugal in search of education, especially in the 20th century. Yet following the annexation of Goa by India, many Goans, particularly those working in government and the military, accepted the state’s offer of Portuguese citizenship and made their way to Europe.

When we first entered Titú, a new spot in the trendy Botafogo neighborhood, our mind immediately went to SpongeBob SquarePants, oddly enough, or more specifically, the Krusty Krab, the diner where SpongeBob works as a fry cook. Like the Krusty Krab, this recently opened bar specializes in seafood burgers – when we popped our head into kitchen, we saw a mountain of patties awaiting the grill. The only difference between Krusty and Titú – besides the fact that latter is real and the former is merely a fantasy under the sea – is that at Titú the burgers are not made of crab, but of octopus. Delicious and tender baby octopuses, captured in the waters off the coast of Rio de Janeiro.

Each year in late summer, some of the best athletes on the planet converge on Flushing Meadows Corona Park to compete in the United States Open Tennis Championships. In 2018, the U.S. Open begins with practice sessions and qualifier matches on Tuesday, August 21, and concludes with the men’s singles final, scheduled for Sunday, September 9. The tournament site does provide hungry fans with several cafés and casual bar-restaurants as well as a pair of “food villages.” But when in Queens – where some of the best food in the city is so close at hand – why would we confine ourselves to the boundaries of the tennis center? To energize ourselves beforehand or wind down afterward, here are a few of our favorite nearby dining destinations.

Editor’s note: It’s Beat the Heat Week at Culinary Backstreets, and in this week’s stories, we’re sharing some of our favorite spots to visit when the summer temperatures soar. One of the great joys of spring and summertime in Istanbul is the chance to get away for a day to one of the Princes’ Islands, the car-free and forested archipelago that is a short ferry ride away from the city. The only downside to an island hop is actually getting there: as soon as spring makes its first appearance in Istanbul, the hordes descend on the mainland’s ferry terminal, filling the boats to beyond capacity (at least on the weekends).

Street life still remains a big part of the port zone’s narrow alleys, which are lined with small traditional shops and restaurants, many with a big charcoal grill out front for cooking up whatever fish is in season. We sample several preparations of seasonal fish and seafood on our Song of the Sea walk in Lisbon.
