Twenty years ago, Rio de Janeiro was teeming with food markets: big indoor venues full of stalls where people could go to buy groceries, fresh meat and produce, but also stay for a while to have a drink or two, maybe some appetizers, or even sit down for a meal. As time went by cariocas spent less time in these markets, instead shopping in grocery stores and eating at restaurants; the markets continued to limp forward only because of some strong-willed and stubborn merchants who refused to shut down their businesses.

Our eyes take a moment to adjust to the dim light upon walking into Ladrio. The room is like a vault, its brick walls and floor emitting a scent familiar to anyone who’s ever been in a cave or stone cellar. This mustiness is comforting, however, and the cool air a welcome reprieve from the furnace of the Tokyo summer outside. Soon we can make out several low tables extending back into the narrow space. People sit alone or in pairs sipping coffee or puffing cigarettes. Some converse in hushed tones as Edith Piaf is piped quietly from an unseen stereo. A few heads swivel in our direction but gazes never linger here.

While on our Downtown Athens walk, we spied a grill master preparing his souvlaki on a hot griddle rather than on the customary charcoal fire – as we learned, this style of cooking has enraged many a purist over the years. Yet the result is still juicy and exceptionally filling, so we’re not complaining.

All morning, as we zoomed down south from Naples on a motorcycle, inky clouds threatened rain. So when we arrive at Rivabianca, a mozzarella di bufala cooperative in the village of Paestum, with our clothes still dry, we exhale deeply, not realizing that we had been holding our breath. Inside the dairy’s production center, separated from the small shop by large windows and a big metal door, it looks as if the rain has already come and gone – the tile floor is covered in water. “Wait just a sec, you’ll need these to go inside,” says Rosa Maria Wedig, the owner of Rivabianca, handing us two plastic bags. Before we can make a move, she’s bending down and shoving them on our feet, using duct tape to secure them around our ankles.

New York’s street food vendors usually ply their trade where potential customers congregate. On side streets in midtown Manhattan, they set up four and five abreast for the weekday lunch rush. During warm-weather weekends, they feed footballers and their fans outside ball fields in the Brooklyn neighborhoods of Red Hook and East New York. In Queens, they do business beside a miles-long stretch of Roosevelt Avenue where it passes through Woodside, Jackson Heights, Elmhurst, and Corona; they cluster thickly near station stops of the elevated 7 train. The setting of the D’Angelos Italian Sausage truck presents a dramatic contrast. Monday through Saturday, the truck parks in a long-established spot on Woodhaven Boulevard, on the border between two largely residential neighborhoods, Middle Village and Rego Park, beside the green expanse of St. John Cemetery.

Matosinhos, a small city just north of Porto, is used to change. It has an industrial air to it, due to its 19th-century harbor, and its past prosperity was connected to the fish-canning sector, which peaked during World War II and declined from the beginning of the 70s. The numerous abandoned warehouses attracted nightlife during the 1990s, with clubs finding a fertile zone for noise. The completion of the long-delayed tidal pool, built by Portugal's starchitect, Alvaro Siza (who was born in the city), put it firmly on the map again after the project was delayed for decades. In January, the launch of the new, spiralling cruise ship terminal added to the contemporary design-y feel that has been developing on its otherwise rugged coastline.

A few intrepid trajinera (gondola) operators sit along the Cuemanco Dock, waiting for tourists to take through the canals. We’re in Xochimilco, the southern-most borough of Mexico City. It’s a popular weekend destination for trajinera rides, when entire extended families float along the canals, drinking micheladas (beer cocktails) and eating elotes (grilled whole corn cobs) sold off canoes. But this weekday morning is quiet. As the morning fog burns off, we set out on a green, motorized trajinera into Xochimilco’s Natural Protected Area. Before it was a preferred weekend getaway for chilangos, Xochimilco was the agricultural heart of the Aztec capital Tenochtitlan. Our destination is a chinampa, a man-made agricultural plot that “floats” on the city’s shallow lakebeds.

Over the course of June, Lisbon’s neighborhoods are perfumed with the smoke of barbecued sardines. It’s one of the most prominent features of the traditional arraiais, the festivals that pop in each neighborhood at this time of year, offering grilled fish and pork, beer and sangria, and music. While all this eating, drinking and making merry is certainly a fun time, it’s by no means the main event. For many Lisboetas the highlight of the June festivals, which are held in honor of Santo António, Lisbon’s favorite local saint, are the marchas (parades) on the night of June 12, the eve of Saint Anthony’s Day. It’s the moment they have been waiting and preparing for all year.

Fishmongers are getting ready for the Santo António Festival, which the city celebrates by grilling up copious amounts of sardines – large swathes of Lisbon turn into one extended outdoor cookout. We spotted these festive workers in Campo de Ourique market, on our Lisbon Awakens walk.

Dozens of urban legends swirl around the city of Naples – strange stories repeated a thousand times that, somewhere along the line, become credible. One of those urban legends concerns biscotti all’amarena, or black cherry cookies: people often say that they are made from day-old cakes. To create this typical Neapolitan sweet, bakers chop up pan di spagna (sponge cake) – the bit that is supposedly reused – and then mix it with black cherry syrup, cocoa and cinnamon. The mixture is then covered with a short-crust pastry shell and baked as a loaf, after which they’re cut into small rectangles.

Ramadan fasters in Istanbul may not love the endless daylight hours in summer nor the susuzluk (no water), but when the reward is a leisurely iftar under the trees on Kadınlar Pazarı, the pedestrianized market known as Little Siirt (named after the southeastern Turkish city where many of the local shop and restaurant owners hail from), it must surely seem worth it. A February iftar would not be quite the same, at least not in Turkey. As we walked through the twilight to Siirt Şeref Büryan Kebap Salonu at the end of the square last Saturday, hundreds of fasters waited in front of cling-filmed plates of iceberg lettuce and ciǧ köfte for the Ramadan cannon to signal “breakfast” time.

The best part of waking up in Istanbul is catching sight of the Bosphorus, followed closely by a breakfast of simit, the popular sesame-encrusted bagel-like Turkish bread. We spotted this simit seller in Üsküdar while on our Born on the Bosphorus walk.

Georgians swear that natural wine does not give you a hangover, but something is keeping us in bed watching superhero series on Netflix and it is not the compelling storylines. Vato Botsvadze, owner of Chacha Corner was also at Zero Compromise yesterday. He will insist in all seriousness that his morning headache was a result of the rain, which stopped just before the greatest party in Georgia started. We’re talking about the eighth New Wine Festival, organized by the Georgian Wine Club, a group of over a half dozen wine enthusiasts who have been at the forefront of developing, promoting and educating people about Georgian wine since 2007, when they turned their internet forum into a blog and started hosting wine tastings across the country.

When I was a little girl, a Popsicle was a big deal. Summertime meant that the ice cream truck, bell tinkling, would trundle through the neighborhood where I lived. After a frantic plea to Mom for money, she counted out coins and I raced to the corner where the rest of the kids were already gathered, waiting for the vendor to dig through his icy case for cherry, lime, orange, or the reviled banana. The odor of amyl acetate (the chemical used for artificial banana flavoring) remains cloyingly in my memory. Remember? Hot summer days made those frozen snacks melt quickly, down childish fingers and the side of the hand, down the wrist and almost to the elbow in sticky trails of blood red and pale green. Nips of the cold treat slid in a chilly track from tongue to stomach, giving a few moments relief from childhood summers’ heat and humidity.

The song “My Way” may be a staple of every karaoke bar in Japan but it’s also a fitting description for the Japanese fast food staple of “curry rice” as served at both Rojiura Samurai Curry and CoCo Ichibanya. One can find four Tokyo outposts of Rojiura Samurai Curry, a Hokkaido curry maker from Sapporo, in Hachioji, Shimokitazawa, Kakurazaka and our favorite, Kichijoji. It seems these Japanese curry masters are fond of opening shops in cool neighborhoods where the locals will appreciate the uniqueness of this favored Japanese dish. Much like ramen noodles, curry rice is adapted from a foreign cuisine as a form of fast food in Japan.
