When the other butcher shops in Naples are closing for lunch and at the end of the day, activity at D'Ausilio Macelleria is just picking up. The cooktops are lit, sandwiches are being made and this Italian butcher shop becomes a quality burgeria. “I come from Vomero (the hill district) to buy Raffaele’s hamburgers. My children love them,” says customer Rosaria Esposito at 8 p.m., when the macelleria is an hour into its transformation as a burgeria. But this is no trendy burger bar; the menu is steeped in local heritage. Rosaria leaves the burgers to the kids, choosing for herself the delicious home-style dishes created at D’Ausilio. Parmigiana alla Genovese stands out among those on display. Here are two sacred words of Neapolitan cuisine – Parmigiana and Genovese, a simple yet miraculous sauce made of meat (veal, beef or pork) and a heap of onions (red or white) – cornerstones in the history of local cooking.

An espresso coffee is an integral part of most Neapolitans’ morning routine. We start off our walk with a (small) cup of this potent brew and sfogliatella, a pastry first created in a Catholic convent near Naples.

On the walls at Haritna Restaurant are homages to simple sights: a large gate, ancient Damascene windows – it’s a scene that hopes to inspire the very particular feeling of sitting in the middle of a Damascus square, down a well-trodden, old lane. For in Arabic, haritna means “our lane.” Also a colloquial term for neighborhood, Haritna evokes a sense of home for those now living far away. In fact, owner Loay Bakdash, originally from Damascus himself, had dreamed of opening such a restaurant while working as a civil engineer in Saudi Arabia. But he didn’t want it to be a place where people would just come and eat. “I wanted the customers to feel that they are in one of Damascus’ neighborhoods, among their acquaintances in a family-friendly atmosphere,” he says.

Nowhere in Mexico City does one feel the collective weight of the largest population in North America more than on Avenida Lazaro Cardenas, the traffic artery that gushes a surfeit of humans and cars up the heart of the city’s downtown. The gutters stink of rotting fruit. Dirt and littered garbage encrust the sidewalks. And, at rush hour, walking a block means suffering a gauntlet of elbows and hands pushing at you and past you. For the most part, the businesses that line this street offer little comfort. Goods lie in heaps on carpets or hang two feet deep upon the walls of stores seemingly designed to be fire hazards, cramming too many people onto too little floor space.

Athens’ image as a concrete gray city with few green spaces and a lot of traffic might be hard to shake. But would you believe only 6.5km away from the bustling city center lies a beautiful, lush forest with ancient paths and Byzantine monuments – and a little canteen where you can enjoy lunch near an ancient spring? In the forest, a 30-minute walk from the Kaisariani cemetery and off the Kaisariani Monastery loop trail is a bustling picnic area and ancient spring, a well-kept secret of Athens. Come here to seek a rare moment in city life: either snacking on a wooden bench by the water, under the trees awakened by a gentle breeze or at one of the tables and chairs under grass umbrellas by a tiny stone building that serves as the forest’s canteen, Kalopoula Refreshments. Nearby, the Kalopoula spring gurgles and froths, as picnickers and hikers take a break to some surprisingly delicious, traditional Greek food in an oasis of green.

The first few blocks of Baruthane are lined with a smattering of restaurants, barbers, television repair shops and dry cleaners, though in recent years a flurry of third-wave coffee shops and bars has arrived on the street. While this is a positive development for the young adults that patronize these establishments, there is the inevitable concern that their proliferation will cause a spike in rents and tarnish the quaint character of this beloved neighborhood. It is for this reason that we were thrilled to see a new establishment open up on Baruthane that reflects the classic small-business character that makes this area so special. Köy Börek is run by Abdullah Kral, a cheerful 53-year-old teddy bear of a man who makes some of the most delicious börek we’ve ever had – and we’ve had a lot. (Kral means king in Turkish, and we are prepared to crown Abdullah bey the king of börek.)

There was a large table made from a huge buzzsaw blade, covered in Russian and Western photo magazines. A greasy boombox played jazz, blues and classic rock cassettes. Behind the high wooden counter was a somber, dark-haired young woman who served semi-cold Argo beer for 3 lari a bottle and a simple lunch for a few lari more. We had found our watering hole. Apollo had been designed by local artist Guga Kotetishvili, a name we wouldn’t know until 2004, when he helped two young Apollo regulars auspiciously launch an entrepreneurial gastro-dominion with the opening of Cafe Kala on Erekle II Street, a narrow, 100-meter lane in Old Town. Back then, there was nothing else on the street.

Speed down the National Road till you’re in sight of Rendis Market, then follow the trucks off the highway and into a vast depot of concrete sheds. Though the trucks are there to pick up and deliver fruits and veg from all over Greece to supermarkets, grocers’ and farmers’ markets, we pulled over and started shop-hopping. Rendis, an industrial district of small factories, warehouses and train yards on the west side of Athens, has never been an area one would go for pleasure.

A gloppy, meaty, cheesy brick served in a pool of sauce and with a mountain of fries: please meet the francesinha, the culinary pride and joy of the city of Porto. Today, restaurant billboards proclaim in many languages that they serve the best version in the world, revealing the genuine power of this artery-clogging combination that, incredibly, was originally conceived as a snack. We have to say it though: eating a francesinha is worth every last calorie. This dense sandwich, which is impossible to eat just with your hands, is often considered the lusophone version of the croque monsieur.

West Georgia's climate is ideal for tea, and Georgia has been producing high quality tea since 1847. On our Old Market & Beyond culinary walk in Tbilisi, we get a chance to see, smell and taste fine samples of tea and other delicacies in the Dezerter's Bazaar - the Georgian capital’s largest and oldest open-air marketplace.

We’ve been fascinated by dry pot (ma la xiang guo) since discovering it in Flushing last year, probably a decade after it had risen to match the popularity of hot pot in Beijing. This streamlined hot pot is a wok stir-fry of all your favorite hot pot ingredients, served in a large, half-empty bowl, as if the soup had evaporated. Although originally dry pots were also presented on a tableside cooktop, many places, especially those in Flushing’s mall food courts, just serve your meal in a big wooden or metal bowl, expecting that you will eat it quickly and move on.

Has mezcal gone the way of avocado toast, an item that’s become shorthand for cliched hipster trendiness? If you think yes, a visit to Mis Mezcales in Mexico City’s Colonia Roma may be in order. There, you will find Omar Trejo sitting behind his unassuming makeshift bar, parceling out sips to the uninitiated and reminding everyone who stops by his small liquor store devoted to small-batch Mexican distillates that before it became a “buzzy” spirit, mezcal was an elixir heavily-rooted in the soils and stories of Mexico. As Omar makes clear to those who come in, every bottle of mezcal tastes different, even from the same brand, the same agave variety and same year. It’s one of the drink’s greatest strengths and probably one of the greatest frustrations for drinkers who expect the standardization of tequila.

On our Xochimilco culinary excursion in Meixco City, we learn about the chinampas, and how chinamperos are dedicated to keeping Xochimilco’s historic and world-renowned agricultural system afloat.

Stop into one of Spain’s best marisquerías (seafood restaurants) and on the menu you will find a dazzling display of the ocean’s bounty: big meaty clams of different shapes and colors, cockles, scallops, oysters, goose barnacles, spider crabs and lobsters. All will have their own with delectable consistency and texture and their own evocative flavors – from intense, sweet or floral to metallic or rich with umami. And most will likely have come from the waters off the craggy coast of northwest Spain’s untamed Galicia region, harvested by generations of artisan mariscadoras (seafood catchers), Galician women whose lives – and livelihoods – are intimately connected to the sea.
