It was the first of April and an absolutely pristine Istanbul spring day, the kind where one can break a slight sweat walking up a hill then catch a cool breeze in a nearby patch of shade. Returning to the city from a lovely weekend on Büyükada, we were smitten with spring and wanted to indulge in its finest offerings. In a fit of hunger-fueled inspiration, we quickly realized what we were craving: yenidünya kebabı. This spring-only affair is a specialty from southeast Turkey’s Gaziantep where chunks of minced beef and/or lamb are skewered in between sections of newly arisen yenidünya, or loquat, diminutive orange fruits that are as tantalizingly tart as they are sweet.

Istanbul’s T1 tramway is relatively pleasant if you can find a seat, but borders on unbearable if you are on your feet. Back in 2015, we wrote about a trip we took from the line’s first stop all the way to one of its last, which lies way out in the district of Güngören. By the time the tram has made it to this point, it begins to perplexingly share a lane with traffic, voiding the whole point of this type of public transportation. On one weekday evening, we found ourselves standing in a rather contorted position on the beyond-crammed train, a price we were willing to pay for a trip to one of our favorite culinary hotspots. The journey took over an hour. It was well worth it.

Despite the somewhat rundown, seedy feel of Omonia today, for all of the 19th century and a good part of the 20th the neighborhood was the real center of downtown Athens. “No one lives in Athens if he does not spend at least one hour a day in the Hafteia,” wrote the famous writer and playwright Gregorios Xenopoulos in 1913, referring to the blocks around the intersection of Aiolou and Stadiou Streets, so named allegedly after a 19th-century café in the area owned by a Mr. Haftas. The area was a commercial hub, filled with stores, coffee and sweet shops and hotels. It was a place where people would come to shop and while away the day or the evening. Given its popularity, it’s no surprise that Athens’ first large department stores, like Lambropoulos and Katrantzos Sport, opened here in the early 20th century.

Kurtuluş Son Durak is a busy intersection and transit hub that’s a hive of activity 24 hours a day. Marking a transition between the tidy, middle-class Kurtuluş neighborhood and the rough-and-tumble quarters of Dolapdere and Hacıahmet, the area is home to a host of eateries and cafes that never seem to close. Right in the center of it all, we stumbled across a diminutive white van rigged with a makeshift grill. Inside the tiny, elaborately decorated vehicle crouched Yıldırım Usta, a 75-year-old veteran of the kebab trade who has been serving up truly delicious dürüm – kebab wrapped up in flatbread – on Kurtuluş Son Durak for 28 years. He has lived in the area for just under half a century. “You see all these other kebab shops? I was here before all of them,” he told us.

If Istanbul had a city museum, in the 20th-century exhibition we’d expect to walk into a life-sized recreation of Kenan Usta Ocakbaşı, a seminal grill joint in the Beyoğlu district. As visitors descended a few steps into the exhibition, sensors would trigger the harsh light of fluorescent bulbs overhead, illuminating a room covered in photographs of husky men with mustaches posing with a stout man in an apron, grill master Kenan Usta. The somber, groaning warble of the great Arabesque singer Müslüm Gürses would cue up in the visitors’ rented headsets and ducts inside the replica grill would belch out smoke scented authentically by grilled meat.

When we talk about the “suburbs” in Brazil, some may imagine the affluent outer boroughs of London, New York or Singapore. But in Rio de Janeiro, they’re nothing like that. Far from its beautiful beaches, Christ the Redeemer and Sugarloaf Mountain, the city’s suburbs are the opposite of tony – they’re where Rio’s working-class people live. Yet the suburbs are where you can find the most authentic carioca soul. They are home to the biggest favelas, the most important samba schools, Afro-Brazilian religious temples, the majority of football fields and, of course, the best botequins, or local bars.

Inside Barcelona’s lesser-known Mercat de Les Corts is a small, unassuming bar offering up the bounty of the Mediterranean. El Bisaura opens up shop at 6:30 a.m., serving esmorzars de forquilla (hearty Catalan breakfasts like sausage and beans, tripe stew and grilled cuttlefish) to local workers. At lunch, it serves a more refined seafood menu composed of whatever owner Alfonso Puig gets from Peixateria Anna, the fish stand on the other side of the market. The fish and seafood of the day are always seasonal, local and impeccably fresh – which is no surprise, since Puig is also the owner of the fish stand.

Berlin Wall No2 is a rickety wood and plastic-sheeting structure on the pavement right on the Greek-Cypriot side of the “green line,” as the border that divides the Cypriot capital is known. It’s overlooked by guards and is a five-minute stroll from the more stylish eateries in the center of Nicosia’s Old Town. But this little hole-in-the wall serves the best sheftalia we’ve eaten in the city. You could argue about whether these wonderful little nuggets are a form of sausage – what the French would call crepinettes. Two cuts of pork – backfat and loin – are minced, mixed with onions, herbs and seasonings, then encased in caul fat – the membrane that surrounds a pig’s stomach – and grilled over charcoal.

As one approaches the port of Ermoupolis (named after Hermes, the god of commerce), the main town of the island of Syros and capital of the Cyclades, one cannot help but marvel at its beauty and grandeur. Imposing public buildings and private mansions, marble-paved streets, a large Italian-style piazza and numerous churches make the city one of the best preserved examples of 19th-century architecture in Greece. This should not come as a surprise: in the aftermath of the 1821 Greek War of Independence from the Ottoman Empire, Syros developed into an important commercial, cultural and industrial center, as refugees from Asia Minor, Chios, Crete and other areas found a safe haven from the war on the small island.

In Argentina and Uruguay, asado – beef cooked over a parrilla, or open pit grill – is a fundamental part of local culture. On weekends, Sundays especially, grill smoke can be seen rising from backyards, rooftops and even small balconies, as well as, of course, from restaurant ventilators. Out of town, there are asados in chacras (small countryside farms) and in parks and picnic areas in forests. Asado’s defining role in these countries has existed for quite some time; it was even mentioned by Charles Darwin in his journals from 1833, when he was traveling towards Buenos Aires in the company of gauchos and native people.

In Istanbul, there is a single neighborhood where one can find Uzbek mantı, imported Ethiopian spices and hair products, smuggled Armenian brandy, Syrian schwarma and sizzling kebap grilled up by an usta hailing from southeast Turkey’s Diyarbakır. Kumkapı – a shabby seaside strip of century-old homes, Greek and Armenian churches and residents from a vast array of countries that most Americans couldn't pick out on a map – is far and away the most diverse place in Istanbul. Nowhere else comes close. In perpetual motion, Kumkapı is home to a rotating cast of eclectic restaurants that cannot be found anywhere else in the city. Many of these open and close before we can squeeze in a second visit.

Istanbul’s Aksaray district is a difficult place to get to know. It's probably the most diverse district in all of Turkey and with a very high turnover rate. Those Georgian ladies you saw dragging an overstuffed plaid duffel down Buyuk Langa Caddesi yesterday? They might be halfway to Batumi by now. The Syrian family by the bus stop? They may be on their way to meet a man in Izmir about a boat. Who knows? Aksaray’s unknowableness makes some locals uneasy; there's got to be mischief in all that motion, with all of those foreigners. Such is the stigma of Aksaray, den of thieves.

We could devote a weekly column to the culinary treasures of Istanbul’s polyglot Aksaray district and probably never have to worry about running out of things to say. The area is jam-packed with places to eat, and while we've written about many of them, Aksaray just keeps on delivering. Having previously covered the Syrian, Georgian, Azerbaijani and Uighur restaurants that make Aksaray a true patchwork of culinary destinations, our most vulnerable soft spot still lies in the strip of kebab restaurants inspired by the cuisine of southern Turkey’s Hatay and Urfa and located adjacent to the metro station.

The working-class area of Brahami has never been Athens’ hottest gastronomic destination. It is a mostly residential neighborhood, halfway between the city center and the exotic beach-loving southern suburbs. Like most of the city’s suburbs, in the not-so-distant past, this area was once made up mostly of fields. Now formally named Agios Dimitrios (St. Dimitrios, after St. Dimitrios’s church), it has a vibrant local market. It’s also home to Remoutsiko, a family-owned, family-friendly taverna focusing on meat. Housed in an old converted barn, the restaurant has been around for some 30-plus years.

Şehzade Erzurum Cağ Kebabı is one of our favorite places in Istanbul for a satisfying, lamby meal. You could easily walk past its handful of outdoor tables, tucked into a bustling pedestrian-only shopping street in the Sirkeci neighborhood. But if you stay, proprietor and head grill master Özcan Yıldırım will make you an unforgettable dish. Cağ kebabı flips the ubiquitous döner concept on its side: Think layered lamb, lamb tail fat, garlic and spices, roasted on a horizontal spit, in front of a blazing wood fire. As the giant lamb cylinder’s outer edges caramelize, the grill master deftly slides an offset skewer into each glistening morsel, slashes the tender pink meat free from the mothership and repeats this process until your skewer is loaded up with perfect bites of lamb.
