Deep in the trenches of one of the oldest union strongholds in Mexico City, there’s a deeply democratic taquería that manages to bring together office workers, blue-collar workers, locals and tourists alike. When you walk by this place, chaos seems to reign. However, once you step into the current you realize there’s a system that keeps the flow of people, tacos, and drinks under control. Taquería El Progreso started serving beef head, suadero (a cut similar to brisket) and tripe tacos 23 years ago. Javier Ramos, an employee who has been working there since the beginning, told us that at first the taquería was about a third of its current size.

Portuguese gastronomy is at the core of Rio's botequins, the small, often family-run gastrobars spread all over the city. Traditional botequins offer European food and some unique aspects of Brazilian culture – mix you’ll find only in Rio. That being said, it’s hard to say whether Tasca Carvalho, the brand new Portuguese gastrobar in Copacabana, is a typical botequim. Run by two young Portuguese friends newly arrived from Porto, Tasca Carvalho is not a mix, but 100 percent Portuguese. And that makes it unique in Rio's street food landscape. Perhaps the only indication of Brazilian influence you might find at Tasca Carvalho is in the ambience. The tables and benches, spread all over the sidewalk, follow the carioca rules of informality.

The menu at Com-Tradição might not be as revolutionary as the vintage posters on the walls, but it’s certainly democratic and affordable. After all, Com-Tradição is the restaurant of the Associação 25 de Abril, founded by the military men who planned the 1974 Carnation Revolution, the coup that ended Portugal’s fascist regime and restored democracy. Nowadays anyone can become a member of this non-profit association. Besides preserving the spirit of the revolution, it also aims to preserve documents and memories of this historical event. The association is located in a beautiful Bairro Alto old building, whose renovation and interior design were overseen by the renowned architect Álvaro Siza Vieira.

In past centuries, ones of economic hardship, Neapolitans’ ancestors feasted only during religious holidays. It was easier then to distinguish the piatti delle feste, feasting foods, by their richness and variety. In these more prosperous times, and with the availability of raw materials throughout the year, these lavish dishes can be prepared or purchased virtually any time, which makes it seem difficult to talk about “festive meals.” However, with the approach of Easter (and Christmas), many Neapolitans, beyond their religious beliefs, are seized by an irresistible desire to return to family traditions and to eat the dishes prepared by their forebears.

Milky, tart, viscous and slightly foamy. At first glance and sip, there’s little to explain why pulque – a mildly alcoholic drink made by fermenting the fresh sap of certain types of maguey, the same plant used for making mezcal – has remained a trusted companion to Mexican drinkers since Aztec times. Pulque, actually, has not only survived, but, after decades of losing ground to beer and soft drinks and their high-priced marketing campaigns, this workingman’s brew is making a comeback. New pulquerías are popping up in hip Mexico City neighborhoods and attracting a younger crowd while old pulquerías, which endured some lean times, are seeing an influx of new customers, who now sit side-by-side with older generations of loyal pulque drinkers.

In the past year, we’ve seen more new noodle houses hawking spicy Chengdu and Chongqing style noodles than we can count on two hands. Very few of the Shanghai-based noodle houses do the fly restaurants of Chengdu justice. Some dish out bowls of insipid strands that barely register on the Scoville scale, while others go for that unbalanced, burn-your-face-off flare that means the chef has likely never been to Sichuan, much less studied the careful art of the region’s balanced cooking. Liu Dao Men is among the exceptions, carefully walking the tightrope of spicy yet tasty, with its menu of Chengdu noodle classics.

Some sociologists say that Spanish society and culture can’t be properly understood without spending time in its bars. You can find bars in mountain refuges, subway stations, on the beach and by the highway. In Barcelona, there are as many bars as taxis and ten times more bars than bookshops. In fact, a recent study by Coca-Cola found that in Spain there’s a bar for every 132 Spaniards. The same study points out that a third of Spaniards wouldn’t hesitate to leave their house keys at their local bar and that two-thirds of them are on a first-name basis with the employees there.

It’s Sunday morning at La Pignasecca market in Naples and time is in flux. Picture a Boccioni painting: movement is blurred, there is an inter-penetration of objects, speeding vehicles and sound – a frenetic moment in the Futurists’ imagination. The city rises as engines splutter, traders hustle, klaxons yelp. Santa Maria di Montesanto spews punters out into the marketplace after mass; men peel off, heading home to check on the simmering ragù; groomed teenagers peacock on mopeds as groups of women push in line to pick up their last-minute order of fresh pasta, charcuterie and squid. The church bells chime: it’s lunchtime. Anticipation is in the air.

It all started with a seriously delicious hamburger in New York City. Rumor has it that it was this burger that first gave acclaimed Catalan chef Oriol Rovira the idea of opening Sagàs Pagesos y Cuiners (“Farmers and Cooks”) in the Born district of Barcelona. Specializing in high-end sandwiches, the restaurant embraces the farm-to-table philosophy, with a menu that is both distinctively Catalan and international in scope. Rovira, who also runs Els Casals, a Michelin-starred restaurant in the tiny village of Sagàs near the edge of the Pyrenees, opened his sandwich spot in May 2011. As at Els Casals, nearly all of the food at the Barcelona venue comes straight from the chef’s village farm. But why sandwiches?

To make excellent octopus broth, you must first fill a huge pot with water to the brim – at least 20 liters – bring it to a boil, add salt and pepper in industrial quantities and immerse four large octopuses. After 33 minutes (and not one more) of simmering, it’s ready: the octopus has reached the perfect consistency. Yet in Naples there’s a saying, “The octopus cooks in its own water” – a proverb that means that a person needs to get to the truth on his own and in his own time. Lello tells us that what this saying is referring to isn’t actually true, since clearly, an octopus needs much more water than what it comes with to actually cook.

On the left bank of Tbilisi’s Mtkvari River in the Plekhanov district is David Aghmashenebeli Avenue, a thoroughfare long associated with wallet-friendly Turkish restaurants and discount clothing boutiques. Some 15 years ago, the crumbling 19th-century buildings and huge eucalyptus trees that lined the street were crowded with people hawking everything from wooden utensils to costume jewelry, fresh produce and coffee beans labeled “Nescafé.” It was a congested, lively sidewalk bazaar of sorts that exemplified the Asiatic spirit of Tbilisi. However, a massive urban renewal project in 2011 put an end to the colorful disorder. Today, most of Aghmashenebeli is a sensible European-looking boulevard that the former President of Georgia likened to Paris, although the Turkish restaurants are still there serving up tasty Anatolian specialties.

Neapolitan cuisine encompasses such a variety of dishes, ingredients and preparations that sitting down for lunch in Naples is always a feast of smells, tastes, colors and sensations. Menus here are populated by numerous meat dishes and equally many seafood options, and the extraordinary variety of vegetables are complemented by unique dairy products, preserves and sweets steeped in history and quality. Restaurant kitchens know how to be baroque (as demonstrated by menesta maretata, a complex soup that “marries” a variety of vegetables and cuts of meat), sumptuous (as in eggplant parmigiana), or deceptively simple (as in the classic spaghetti aglio e olio, which combines the basic trio of pasta, garlic and oil to great effect).

Mexico City can be quite lacking when it comes to finding fresh, tasty seafood. At most markets in the city, in addition to the taco places and tlacoyo vendors, there is usually some kind of stand selling seafood, but the quality can be either very good or very bad. Buying from the right place is thus essential, and that’s why we were so happy to discover La Morenita, a standout seafood and oyster restaurant in Colonia Roma’s Mercado Medellín. Established more than three decades ago by Miguel Gardono, La Morenita has become a busy, reliable stop for shoppers.

Jambú-infused cachaça is bitter and a bit grassy, and newcomers to the drink often grimace at first taste. But seconds later something happens: the liquor's harshness gives way to a gentle tingling, then numbness, first on the tip of the tongue, then to the lips and the back of the throat. Next, the mouth salivates, pulses, and other foods and drinks take on new flavors: a cheap beer suddenly tastes like champagne. The second quaff is often taken much more eagerly than the first. Jambú, or acmella oleracea, is a flowering herb found throughout the Amazon and other warm, humid climates.

The Michelin Guide might have come to Shanghai last year, but the far more interesting trend for budget diners in the city is the fast-casual local restaurants opened by savvy young Chinese with an eye for design and a great palate. The Noodlista is one such shop – just check out its logo. The character for noodles is warped into a downward facing arrow, as if to say, “Get your noodles here!” It’s good advice, and local millennials are taking it: come lunchtime, Noodlista is always packed to the gills with young worker bees from nearby office towers. Showcasing the management’s fluency with both Eastern and Western cultures, English and Chinese coexist happily on the menu.
