In the latest installment of our recurring feature First Stop, we asked chef Massimiliano Alajmo where he heads first for food when he arrives in Barcelona. Alajmo is the chef of Le Calandre, in Padua, Italy, which received its third Michelin star in 2002, making Alajmo, at 28, the youngest chef to ever achieve that distinction.

With its festive atmosphere, excellent grilled ribs and ice-cold beers, Cachambeer attracts hundreds of hungry cariocas and tourists to the suburb of Cachambi nearly every day. It’s one of Rio’s most popular botequins, but it all started merely by chance.

Dear Culinary Backstreets, I’ve heard some horror stories about food safety scandals in China. How does an adventurous eater explore Shanghai without having any culinary misadventures? There’s no hiding the fact that recent years have seen the highly publicized exposure of some unsavory information on China’s food safety record. While the headlines may not be any worse than those seen recently in other countries (whether unlabeled horse meat or fecal matter in ground turkey), the Chinese lately have reached appalling levels of creativity in their food scandals, from thousands of diseased pigs washing up in the Huangpu River, to rat, fox and mink meat being pawned off as lamb at hotpot restaurants.

Looking at a map of the southern Caucasus, you’d expect Azerbaijan to be the next big thing in the world of food, sandwiched as it is between culinary heavyweights Georgia and Iran, connected as it is in so many ways to Anatolian Turkey. Previous trips to that country have not delivered, though. The last time we were in Baku, we landed hungry and curious and left disappointed by a trip whose gustatory high point was pints and bar snacks at a pub called Camel’s Toe.

Cantonese seafood restaurants are almost always stuffy dining institutions, with gilded menus listing astronomically priced shark’s fin soup and braised abalone in private dining rooms with gaudy chandeliers. Like a rebellious younger sibling, Apo’s Seafood has taken the marine Canto theme down a road more graffitied, democratizing the experience by scrapping the stuffiness and serving up affordable, delicious fare from the ocean.

Providing something simple, cheap and good to eat in Spain is easy – as long as there’s a proper fire exit and plumbing. Life is harder for street vendors and food trucks: Spanish law permits cooking and selling fresh (unpackaged) food in street stalls only during festivals or events or in markets run by an organization.

Editor's Note: Sadly, Nordestino Carioca is now closed. In Brazil, the nordeste, or northeast, is the poorest region of the country. In the last 50 years, the harsh climate and lack of job opportunities in the cities have caused a massive migration of nordestinos to more developed centers, like São Paulo and Rio de Janeiro.

In Athens’ western suburbs, near bustling Bournazi Square, sits Base Grill, a steakhouse where regulars converge from every part of Athens. At their restaurant, twin brothers Spiros and Vangelis Liakos have taken the art of grilling to new heights. Base Grill has the atmosphere of a modern tavern: old posters on the walls, soft colors, nothing extravagant. The space is often packed, so we recommend reserving – especially on weekends.

Editor’s note: We asked writer JJ Goode where he heads first for food when he lands in Mexico City. He has written about food and travel for The New York Times, The Wall Street Journal, Gourmet, Bon Appétit and many other publications. He is also the co-author of Pok Pok: Food and Stories from the Streets, Homes, and Roadside Restaurants of Thailand, with Andy Ricker; A Girl and Her Pig, with April Bloomfield; Truly Mexican andTacos, Tortas, and Tamales, with Roberto Santibañez; and Morimoto: The New Art of Japanese Cooking, with Masaharu Morimoto.

Editor's note: We're sorry to report that the vendors and restaurants at Sipalou Lu and Fangbang Lu have suffered the same fate as those on Wujiang Lu and have been shut down. For street food, head to the area around Er Guang. In the lead-up to the 2010 World Expo, the government tore down one of Shanghai’s most famous food streets, Wujiang Lu, so the city would appear more “civilized” in the eyes of businesspeople and tourists visiting from around the world. Sparkling cookie-cutter international brands replaced family-run hawker stalls, and Wujiang Lu’s fried bun purveyors and stinky tofu vendors were scattered across the city. But its sad fate, which left a gaping hole in the city’s culinary landscape, also created new opportunities, allowing Fangbang Lu to become one of the city’s top food streets.

Editor's note: We're sorry to report that Kelly's Cookbookstore has closed. Thinking we’d find something like New York City’s Kitchen Arts and Letters or London’s Books for Cooks, we paid a visit to Kelly’s Cookbookstore near Omonia Square. Like them, the shop is warm and inviting, its owners encyclopedic sources on all matters culinary. Unlike them, it also doubles as an emporium for select kitchen accessories, chefs’ outfits and especially knives. In fact, displayed on the wall opposite the bookshelves, the knives seemed to outnumber the books, most of which are in Greek.

Ivan Rodríguez Vivancos is el tiet, Catalan for “the uncle,” a nickname given to him by the cooks who worked under him at renowned fine-dining restaurant La Terraza del Claris. Today, “El Tiet” is at the helm of his own restaurant, away from the stressful environment of alta cocina, in a place where he can also transport his customers away from the stress of daily urban living.

Editor's Note: Sadly, this spot is now closed. It sounds like material ripe for a bromance film: four college students – all childhood buddies – take an epic road trip together in the 1990s during Carnival to a Rio beach town and rent a separate truck just to transport their 800 bottles of beer. Fast-forward a few years: each eventually settles down and goes his separate way – a phone company executive, a tax lawyer, a law grad, a gourmet chef. But each lives a life outside of his ho-hum routine one – a second life that involves copious amounts of beer.

On our list of favorite Mexican comfort foods, the tamal would likely come in near the top. Simple, yet extremely versatile, tamales share pre-Hispanic roots with the tortilla. A corn masa very similar to the kind created during the nixtamalization process to make tortillas is used as the base for delicious tamales. Recently, we found a first-rate version of this ancient food from a new street vendor located just blocks from the Monumento a la Revolución.

Dear Culinary Backstreets,I love to cook as much as I love to eat, and on my upcoming trip to Shanghai, I’d love to take a cooking class to learn more about Chinese cooking and ingredients. Where can I take English-language cooking classes in the city? With the typical Chinese menu offering 100-plus items, there is a world of Chinese cooking to be discovered, whether you’re in Shanghai for a brief trip or an extended expat adventure. Learning the cooking methods behind some of your favorite dishes will give you the tools to recreate (and adapt to your tastes) your favorite dishes at home using ingredients commonly found in neighborhood markets. One of the biggest expenses expats face in the city is relying on imported food to make Western dishes, which can provide even more incentive to learn to cook local delicacies.
