In & Out arrived in Beijing years ago to rave reviews, but the Yunnan restaurant only just settled in Shanghai, confusing homesick Californians with its name. Instead of Double-Double burgers and Animal-Style fries, it serves cross-the-bridge noodles (过桥米线, guòqiáo mǐxiàn) and fried potato balls (土豆球, tǔdòu qiú). While most Yunnan restaurants in China span the whole province’s cuisine, from tea leaf salads to crispy adzuki beans, In & Out’s menu is (mostly) specific to Lijiang, a city deemed a UNESCO heritage site that lies about halfway between Shangri-La and Kunming, the provincial capital, and is home to the Naxi and several other ethnic minorities.

We recently spoke to food historian and researcher Priscilla Mary Işın about her new book, “Bountiful Empire: A History of Ottoman Cuisine” (Reaktion Books; May 2018). She has previously published edited transcriptions of texts relating to Ottoman food culture and “Sherbet and Spice: The Complete Story of Turkish Sweets and Desserts” (2008), a social history of Ottoman sweets and puddings.

The late Greek shipping magnate Aristotle Onassis may be world-famous, but no one could have guessed that he would be the source of inspiration for a neighborhood kebab place in a residential suburb of Athens. Onassis, who was commonly called Ari or Aristos, was born in 1906 in Smyrna (now Izmir, Turkey), only to later flee with his family to Greece in 1922, during the Greco-Turkish War. Poor but with a grand vision and a great mind, he went on to become one of the richest and most successful businessmen in the world. When Vasilis and Panayiotis, who also own other successful eateries in town, opened their kebab restaurant Kyr-Aristos (kyr is short/slang for kyrios, which can be translated as “mister”) in spring 2013, they decided to name it after Onassis, a refugee from Smyrna, where kebab was a traditional food.

On a recent visit to the market of Sant’Antonio Abate, a pilgrimage site for fresh produce, we made friends with Salvatore, a young Neapolitan chef who was buying fruit and vegetables for his restaurant. We thought nothing of it until we bumped into him again, this time when he was buying fresh bluefish, the symbol and pride, he told us, of his restaurant. Our curiosity piqued, we asked where he worked. Mimì alla Ferrovia, he told us, a name we immediately recognized – it’s one of the custodians of Neapolitan gastronomic orthodoxy. And Salvatore Giugliano, an innovative young chef of 27, is now at the helm of this historic restaurant.

In an ideal world, all fish restaurants would be like Casa Ideal, with its fresh red mullet, proper fish stews with rice, lovely staff taking care of your orders and affordable prices. Also in an ideal world, we would have visited Casa Ideal much earlier. We first heard about the restaurant, which for 40 years has operated in the backstreets of Trafaria on the south bank of the Tagus River, some time ago but never made the time to stop in for a bite. Yet after learning that the restaurant had changed hands a year and a half ago – 54-year-old Conceição Augusto took over from her sister and brother-in-law, and now runs Casa Ideal with her cousins Gabriela Carmo, who works in the kitchen, and Delfim Carlos Gomes, who works behind the counter – we decided to check it out.

The neighborhood of San Miguel Chapultepec sits on the west end of Mexico City’s hipster corridor that runs east through Condesa and on to Roma. In the last decade, these neighborhoods have flowered with bars and restaurants fed by tourists and young people eager to impress. The corridor also had the terrible misfortune of being in the crosshairs of the 7.1 magnitude earthquake that struck the city shortly after 1 p.m. on September 19, 2017, toppling familiar buildings and sending all pretense crashing to the floor.

It’s always tempting to try and take on all three major museums in Tokyo’s Art Triangle in one day. It would be easy to be overwhelmed by the delicious treasures of the National Art Center Tokyo, the Suntory Museum of Art and the Mori Art Museum, so we usually opt for just one and head to Naniwa afterwards for a pot of tea and their delicious taiyaki, a popular form of Japanese sweets (wagashi). The classic version of taiyaki is a fish-shaped pastry with a waffle-like exterior and a filling of red bean (adzuki) paste, though there are plenty of variations encasing chocolate, cream, custard or some other luscious filling. The finished delicacy is best eaten freshly baked, although many people enjoy it at home reheated. Taiyaki resembles a red snapper (tai or madai), which is considered an auspicious fish in Asia.

We had heard about Kiwi Vegan Café even before a dozen thuggish carnivores raided the little vegan restaurant in 2016, munching grilled meat, smoking cigarettes, throwing sausages and fish at customers and starting a brawl that spilled out onto the street. The incident grabbed international headlines, setting the café as a battleground of Western liberalism versus Georgian nationalist extremism. Indeed, many Georgians fear their identity is threatened by “non-traditional” values, such as homosexuality, non-Orthodox religions and electronic music culture. In a land that boasts of its longstanding virtue of tolerance we are seeing a rise in neo-fascist groups and xenophobia.

The vast country of China has just one time zone, so Shanghai’s East Coast location means darkness comes early and most residents usually eat by nightfall, with restaurants often closing their kitchens around 9 p.m. But for those who keep late hours, there are a few late night supper spots around town. Aggressive government crackdowns on hawker stalls have driven many of the late night street vendors indoors, and our top five list goes beyond these roving vendors to feature a mix of restaurants that stay open late and small family-run gems that cater exclusively to the night-owl crowd.

Cumhuriyet Avenue bridges the central Istanbul districts of Beyoğlu and Şişli, and is flanked on its eastern side by a number of large complexes including the city’s expansive Military Museum, the iconic Hilton and Divan Hotels, a towering officer’s club, and a public theater and convention center. In contrast, its western strip consists of a lengthy row of multistory apartment buildings, mostly modern but with a few gems from the turn of the century, housing tourism agencies and foreign consulates. Behind these lie the Harbiye quarter, home to a collection of smaller, charming historic buildings, most of which have seen much better days. It is a generally safe area if a bit seedy, with a number of questionable nightclubs on basement floors.

Cal Pep is a name you’ll find across Barcelona, but it takes on a different meaning depending on which neighborhood you’re in. In Gràcia, the name Cal Pep is synonymous with an old bar-bodega, dedicated almost entirely to the business of drinking (Carrer de Verdi, 141). The Cal Pep in Born is a famous seafood restaurant in Born (Plaça de les Olles, 8), with lines snaking out the door. In Sants, Cal Pep is affixed to a charismatic bodegueta (small bodega). Narrow, long and dimly lit, this particular Cal Pep has the atmosphere of a wine temple – including wooden casks and a vintage fridge – that has been frozen in time, with most of the original decorations from 1927 still intact.

Surely Plateia Viktorias is one of the last places you’d look if you wanted to find a typical seaside taverna. The square, once a meeting place for Patission Avenue’s haute bourgeoisie in the first half of the 20th century, was filled with refugee tents and sleeping bags just a few years ago. Today it still boasts the city’s largest concentration of refugee help centers, and women with head scarves push prams through it, while Syrian and Afghan lads lounge on its ledges playing with their cell phones. We first noticed the eatery, at the very end of a two-block pedestrianized street called Hope (Elpidos), while on our way to lunch at the Victoria Art Project, an initiative born during last summer’s Documenta 14 art festival to foster creativity in the neighborhood.

Several thousand years ago, or so the story goes in Naples, Lucifer and Jesus had a massive showdown in the rarified kingdom of heaven. After a raging session fueled by sibling rivalries, and which likely included satanic petulance and the occasional errant lightening bolt, God, as any parent of battling children can grasp, had had enough of the celestial brawling. One can almost imagine Jesus yelping, “He started it,” as Lucifer tosses a fireball in his direction. So God cast Lucifer into the depths of hell – consigning him to an eternity of fire, brimstone and heat. (In the original pagan legend, this quarrel was between Bacchus and Pluto; after Christianity swept across the region, Neapolitans changed the names of the main characters, but the story remained the same.)

Japanese cuisine is often the art of quiet subtlety, and to that end, salt is one of its greatest supporters. The freshest of fish can be highlighted with a splash of the correct salt; cold sake drunk from fragrant cedar vessels is well enhanced with salt on the rim; and even tempura is frequently not dunked in sauce but instead sprinkled with salt by serious connoisseurs of fried delicacies. Salt plays a very significant role in Japanese culture and religion. It is a sign of purification. Thus most sushi restaurants mound salt on both sides of the entrance to show the place is clean and pure. Sumo wrestlers will throw salt into the ring before a match. Japanese people frequently throw salt over the entrance to their homes to purify their households. We’ve even seen people with packets of salt in their car.

The diverse bay of the Sado River estuary, with its old port towns, cork oak groves, ancient rice fields, beaches and wildlife, is only around 45 minutes south of Lisbon, but feels a million miles away from the Portuguese capital. The history of this region – which includes the slightly gritty main city of Setúbal – goes back to Roman times, and it has had a strong connection to the ocean ever since. Fish salting has been key to Setúbal’s economy from the first century onwards, with port activities developing in the 15th century and later more industrial development, particularly fish canning, in the 19th century.
