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.

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.

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.

“I still don’t know where the siphon bottles for the vermut are,” says an employee of Marina, a small bar in the newly renovated Mercat de Sant Antoni. It’s clear as we’re walking around that the staff of the market’s few bars and its many vendors are still settling in and adapting to their brand new spots. At the same time, hundreds of visitors have been exploring the revamped market each day since its opening last week asking, “Where can we eat or drink something?” So far, that seems to be the question on everyone’s mind, particularly locals. But this is not another food hall, this is a proper neighborhood market focused on selling quality fresh produce and other food product

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.

We’d passed Noisette many times in the (not quite) year that it had been open. But whenever we’d walked down those sometimes clamorous blocks of 30th Avenue in Astoria, Queens – not far from a bagel shop, a pizzeria, a comfort-food hotspot and a New Orleans-themed bar-restaurant, whose windows open wide toward the street during happy hour – we’d given little notice to the quiet bakery-café with the French name. That changed during one recent stroll, not long before dark, when a hand-drawn signboard beside the door wished us “Ramadan Kareem” and beckoned us to come inside.

Kapnikarea, a tiny music café-restaurant, takes its name from the Byzantine church nearby in the middle of Ermou Street. The street, dedicated to Hermes – a god of many attributes, including trade, thievery and smooth talking – and thronged with tourists and shoppers day and night, is an unlikely location for this unusual eatery. You might expect it in neighborhoods like Psyrri or Exarchia, where the eccentric is commonplace, but not opposite H&M and in the same zone as Zara and Marks & Spencer. In all fairness, Kapnikarea was there first. And when it opened in 1977, it was an avant-garde sandwich shop, a pioneer in the land of souvlaki and spanakopita. This version of fast food barely existed back then although it caught on fast. Nineteen years later, Dimitris Sofos took over the shop from his father and completely transformed it.

Sichuan cuisine is famous for its mouth-numbing, spicy flavors, but what many people don’t know is that the provincial cuisine is subdivided into several specialty subregional cuisines. One of our favorites is Xiaohe Sichuan cuisine, which hails from the cities of Zigong, Luzhou and Yibin in the province’s southern region. Originally famous for its salt mining, the Xiaohe (which means “small river”) region is now perhaps best known for the Zigong Dinosaur Museum, a monumental museum built over a dig site that’s had an incredible number of dinosaur finds. But the local cuisine – renowned for being spicy and creative – is worth exploring.

Usually Greek coffee is prepared in a special tiny aluminum or copper pot called a briki over low heat on a stovetop. But on our walk in Keramikos, we spied a briki nestled in a bed of hot sand, another way of heating the drink. Some say that the slowness of this cooking method lends itself to a smoother, more flavorful Greek coffee.
