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.

If there is a word to describe the Laranjeiras (“Orange Trees”) neighborhood, it is “pleasant.” Agradável. Agreeable. As you walk up its main drag, Laranjeiras Street, you pass by the creamy yellow and white façade of the elegant 19th-century National Institute for the Education of the Deaf on your right. Soon, on your left, you could come across the youth orchestra Camerata Laranjeiras playing free concerts at the General Glicério fair. It’s measurably Rio’s most progressive neighborhood – in the 2012 mayoral election, it was the neighborhood that most favored human rights activists and opposition candidate Marcelo Freixo (48 percent of the neighborhood voted for him in the election against Mayor Eduardo Paes, whereas the city as a whole voted only 28 percent for Freixo). Follow the rising street to its top and you’ll find yourself at the tourist train, ready to go visit the Christ statue.

Here in Mexico City, there are many restaurantes yucatecos that serve the cooking of the Mayan states, including two of our favorites, Máare and Coox Hanal. And a few months ago, an eatery with a fresh take on Yucatecan food opened its doors in Colonia San Rafael. As its name indicates, Cochinita Power specializes in the region’s best-known dish, cochinita pibil. The traditional version consists of pork marinated in an acidic sauce made from achiote (annatto seeds) and Seville oranges, wrapped in banana leaves and roasted in an underground pit. At Cochinita Power, the meat is not roasted underground, but chef Alexis Estrada cooks the mouthwatering cochinita on the stovetop until the meat is incredibly tender and deeply imbued with all the spices and flavorings he adds to it.

The Praça da Bandeira, an area of Rio that until recent years was mostly known for prostitution and cheap inner-city housing, is rapidly changing. Lying in the shadow of the massive Maracanã Stadium – built for the 1950 World Cup and the planned location of the opening ceremony of the 2016 Summer Olympics – it is alive with new construction and pedestrian traffic, which are changing the tired face of this historical but underappreciated neighborhood. And sitting snugly in the midst of this new buzz is Aconchego Carioca, a restaurant and bar with one of the best beer menus in Rio.

Coca is a word used in Catalonia and neighboring regions for many kinds of baked doughs and pastries, both sweet and savory. The Catalan and Occitan word has the same root as “cake” and comes from the Dutch word kok, which entered the local lexicon during the reign of the Carolingians in Catalonia (759-809)

Known in Catalan as mongetes – “little nuns,” as Catalonia’s oldest kind of beans resemble the pale face of a nun in her black habit – or fesols, from the Latin phaseolus, beans are an integral part of the region’s culinary traditions. If Catalan home cooking could be represented by a single dish, it would be butifarra amb mongetes, peppery pork sausage which is either grilled or fried and served with a little mountain of delicious beans: simple, filling and soul-warming. But in Catalonia the number of dishes made with legumes is infinite. In fact, many local restaurants offer a choice of beans or potatoes to go with all manner of seafood or meat preparations, from chicken to pork or veal, or from cod to squid or sardines.

Editor’s note: The year is coming to an end, which means it’s time for us to look back on all the great eating experiences we had in 2014 and name our favorites among them. Can Pineda At this tiny, century-old restaurant in the neighborhood of El Clot, we ate a simple dish of guisantes lágrima (“tear-shaped peas”) with little bits of jamón ibérico, one of the most delicious culinary treasures we have had all year – and one we will remember for a long time to come.

Rio’s small traditional bars, known as botequins, are by definition simple establishments, where orders are usually taken down with pen and paper – and sometimes not taken down at all, but mentally noted. But even in these fuss-free eateries, times they are a-changin’.

Horn of plenty, yellow foot, ox tongue, gray knight: the bewitching names are like something out of a fairy tale. But at Casa Lucio, in Sant Antoni, these are all mushrooms you might find on your plate, especially in autumn.

Let’s say you have only two or three days in Rio. You want to experience a little real Brazilian culture and don’t want to restrict yourself to the obvious tourist stops, overhyped bars and restaurants or usual “gringo” nightlife spots. Our recommendation? Spend a night or day – or both, even – at Feira de São Cristóvão.

Editor's Note: Sadly, this spot is now closed. The busy outer neighborhoods of Rio de Janeiro – locals refer to them as “suburbs,” though they are anything but – are full of old bars. Some of the best botequins (small, family-run establishments serving traditional food) have been kicking around in these parts for ages – but not all of them.

Editor's note: We are sad to report that SofrAda has closed. One of our favorite spots to make a quick summer getaway from Istanbul is the idyllic car-free and forested paradise of the Princes’ Islands, located just a short ferry ride away from the city. Here’s where you should eat when you get there.

Churros, the long, skinny, crenellated, sweet fried crullers made from just flour, water and salt, have been enjoyed for centuries in Spain, with hot chocolate and without. However, in Barcelona, xurros, as they are called in Catalan, are becoming an endangered species. In recent years, more than half of the xurrerias in the city have disappeared. Many of the old-timer xurreros who still survive have the odds stacked against them: permit renewal for a street stall is near impossible; rent has become prohibitively expensive and continues to increase; or required updates to old infrastructure might prove extremely costly. However, we know of one young newcomer who has emerged with fresh energy and inspiration, incorporating lessons from the masters in his creative take on xurros. The best way to save this endangered species is to eat it, so here are our five favorite xurrerias, which make these star-shaped doughnuts with great care – and with delicious results that are worth seeking out.

Editor's note: For our last stop on CB's Global Bar Crawl this week, we're pulling up a stool at our favorite mezcal bars in Mexico City, kicking back and savoring every last drop. Para todo mal, mezcal. Para todo bien, también. Y si no tiene remedio, tómate litro y medio. For everything bad, mezcal. For everything good, the same. And if that doesn’t help, drink a liter and a half. – Popular saying among mezcal lovers.

Editor's note: Our third installment in the Global Bar Crawl takes us to Barcelona, where gin continues to be the drink of choice among locals. Tomorrow we head to a spot in Istanbul where you can spend an evening visiting a number of bars, all without leaving the building. Spain is a country that loves a long-drink – alcohol in combination with a soft drink, refreshing and open to invention and reinvention. On the heels of creative gastronomy’s efflorescence in recent years, many old drinks, cuisines and forgotten ingredients have returned, revived through new and more sophisticated techniques and interpretations. The gin and tonic, called gintonic here, is one such Spanish obsession, and all that ingenuity and focus have gone into taking this highball to the next level.
