The 19th-century homes in old Tbilisi neighborhoods were built in a style Georgians call “Italian Courtyards,” where through a gate or arch you enter a quad enclosed by stories of balconies shared by each family on the floor. This courtyard was the nucleus of each building, where kids safely romped around, monitored by adults from the windows above, as men contemplated domino moves at a table under a tree and women beat rugs on an iron rack in a corner.

Comprising a city within a city made of housing complexes and self-built neighborhoods, the Maré favela complex in Rio’s North Zone packs 130,000-plus residents into the area between the Avenida Brasil highway and Guanabara Bay, just south of Rio’s International Airport.

Search online for Shanghai’s best fried dumplings, and you’ll come up with hundreds of results extolling Yang’s Fried Dumplings. Though it was once just a humble shop sandwiched between the Bund and People’s Square, the online renown and ensuing crowds have propelled the brand into chain-store ubiquity, populating new malls and shopping streets with fervor. In essence, they’ve become the Starbucks of dumplings; you’re going to get a relatively consistent product, but come on, you can do so much better! Enter Yang Yang’s.

Editor's note: To inaugurate our new series, Building Blocks, which explores the fundamental ingredients of the cuisines we cover, we turn to Spain, where anchovies play a large role in the cooking of many regions there. Anchoa, boquerón and bocarte: These names – in Spanish, Basque and Catalan, respectively – all describe the same little fish, the anchovy, and to make matters more confusing, the names also indicate how the fish is prepared, depending on what region you’re in.

In South Africa, many roads lead to boerekos. We chose the N7, the tar artery connecting Cape Town and Namibia. After winter rains, the barren land along the way – known as Namaqualand – bursts into spectacular, botanical hotspot bloom. The floral diversity here is unique. Also unique is the local food.

There is an ancient saying in Greek, Theros, Trygos, Polemos, meaning “wheat harvest, wine harvest and war”: All three are situations that need immediate attention and cannot be postponed until later. Hopefully there will be no war, but having completed the wheat harvest, we are nearing the finish line of the wine harvest.

Editor's note: In the latest installment of our ongoing series First Stop, we asked Stavriani Zervakakou, chef of the restaurant Karaköy Gümrük in Istanbul, where she stops first for food when she returns to Athens. Athens rarely lets me down when it comes to food. And although I am a seafood person, the first thing my soul craves after a long stay in Istanbul are grilled juicy pork skewers calmly hugged by the crispy arms of a well-baked pita bread.

We like to think of İnciraltı, a laid-back meyhane in the sleepy Bosphorus-side Beylerbeyi neighborhood, as a destination restaurant – not so much because of the food, but because of the destination itself. Not that there’s anything wrong with the food here, which is reliably well made. The meze tray at İnciraltı (which means “under the fig tree” in Turkish) is brought to your table carrying all the classics, plus a few welcome and tasty surprises, such as the zingy brined twigs of the caper plant and a sea bass fillet that has been cured in a piquant sauce redolent of curry.

Kim Díaz, a well-known local restaurateur and owner of Bar Mut tapas bar and El Mutis cocktail bar, wanted to pay tribute to one of the most humble and sadly underrated Spanish snacks, the sandwich. Sandwiches are generally made by most Barcelonan bars with defrosted cheap bread and greasy fillings, and good ones are not easy to find in the city (though we have written about some great ones). Entrepanes Díaz opened last February with the goal of giving the sandwich the respect it deserves.

The West has gone gaga for noodles, Japan’s most cherished comfort food. Hungry diners pack secret soba dens in Los Angeles for bites of hand-cut anything; they line up to plunk themselves down at sparkling counters offering $100 ramen tastings in New York and pick through ramen au beurre in Paris looking for the next new taste. In Tokyo, ramen masters are now competing for cult status within a ramen culture imported from the United States. Soba chefs are newly coveted for their skill in grinding, rolling, cutting and plating and are praised as master craftsmen.

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.

To the uninitiated, the restaurant owners of a small corner of Istanbul’s Yenibosna neighborhood might come off as having an unhealthy obsession with particularly garish versions of the colors yellow and green. As we recently explored the lower end of the Yenibosna neighborhood, one of Istanbul’s large periphery boroughs, we stumbled upon a small cluster of kebap shops spread out amid a run-down yet bustling strip of auto repair shops and congested rows of apartments, with each eatery’s sign decked out in identical yellow and green trim.

Reviewers are often tempted into using metaphors that portray the restaurant as a sacred place -- the sushi temple, a t-bone pilgrimage, chili-cheese fry heaven. But in Istanbul’s Moda district on the Asian shore, we’ve found a praiseworthy fish restaurant that could justifiably be described as a shrine – literally. For more than 50 years, a local Greek family has been serving saints and sinners alike at Koco, a rambling seaside fish house situated atop an ayazma, or sacred spring. There’s meze and fresh grilled fish with raki upstairs, candles and a shot of holy water downstairs. Judging by the size of the dining room, Koco is preferred by very large groups. One recent weeknight, though, there were just enough customers to fill in the tables lined along the windows. The view of the old Moda ferry dock and the Marmara Sea from the window side of the room is excellent but leaves you leagues from the coat check where the staff hangs on a slow night.

There’s been a revolution taking place in Greece over the last couple of decades, and it doesn’t have much to do with the political and economic turbulence troubling the country – it’s all about wine. Wine in Greece, of course, has ancient origins: The first traces of it were discovered on the island of Crete and date back to 2500 BCE, during the Minoan civilization, and the oldest winepress in the world was found in the ruins of Vathypetro, near Heraklio.

It has been years now since we were first tipped to Sıdıka. The W Hotel had just opened in the splashy Akaretler rowhouse development. Vogue, the rooftop sushi lounge, was still in style. The Shangri-La hotel was under construction down on the waterfront, and it was rumored that some rooms would have Bosphorus views below sea level. Beşiktaş, long the bastion of cheap draft beer joints and university student flatshares, was having some growing pains.
