Hong Kong native and Cha’s owner Charlie Lau became a restaurateur because of a hankering. A movie producer by day, Lau came to Shanghai with Ang Lee to film “Lust/Caution,” and was disappointed that Shanghai lacked a proper Hong Kongese cha canting, a casual all-day eatery that serves traditional Cantonese food alongside milk teas and coffee. So he decided to open his own. On the set of “Lust,” a 1930s period piece, Lau was responsible for ensuring the historical accuracy of the costumes, casting and set design, so it’s not surprising that he designed Cha’s with the past in mind. Walking across the restaurant’s threshold transports you to 1950s Hong Kong.

Can Paixano, the kind of timeless dive that could soon be extinct due to the rise of Western chains, is an obligatory stop for anyone wanting to taste a slice of the real Barcelona. And the bar’s location in Barceloneta, the traditional fishermen’s quarter where the old port meets the beach, provides the perfect setting.

Exarchia is one of Athens’ liveliest neighborhoods. Home to students and intellectuals alike, it’s filled with bookshops, music stores and “free-thinking spaces,” an interesting bookstore/café hybrid where political debates and local residents’ council meetings are sometimes held. The area looks slightly worn-down: the neoclassical and post-war buildings are littered with graffiti tags and music posters, which means – as visitors to other European capitals might know – that there are great places for eating and drinking here.

In the evolutionary process of the Istanbul fish restaurant, there was a moment in the late 1990s when the amphibious, shore-hugging boat restaurants crawled out of the Bosphorus and became land dwellers. Overnight, yellow Wellington boots became black loafers as seafaring grill men became restaurateurs and waiters.

The no-frills Lades 2 presents diners with that age-old question: what to eat first, the chicken or the eggs? A Turkish version of the American-style greasy-spoon diner, this restaurant specializes in all things fowl, from chicken soup to a variety of egg dishes and even a dessert that – we kid you not – weds a thick, milky pudding with chicken. Even the name (“lades” means wishbone) follows the chicken theme.

Catalan owners, Filipino chefs and a menu offering comfort food inspired by the cooking of Iberian sailors: La Flauta, a restaurant-cum-tapas-bar that goes long both on good taste and good value, is an excellent reminder of the benefits of Barcelona’s being a port town.

Let’s be honest: for most of us, city travel is really about eating. Sure, we make plans to visit the local monuments and important museums, but those are merely placeholders.

Twenty years ago, lilong, the tiny alleyways and courtyard houses that make up the backstreets of Shanghai, were packed with tiny mom-and-pop restaurants serving longtang cai, alleyway cuisine, to office workers and neighboring residents. But as the city’s construction boom demolished many of these lanes, the longtang dishes went back into grandmothers’ kitchens, only available to those who were heading home for lunch.

For Turks, mealtime is often a complicated emotional drama, one that revolves around a lifelong effort to return to the culinary womb – in other words, Mother’s kitchen. In Turkey, Mom’s cooking sets the standard by which all others are judged and, truth be told, some of the finest meals we’ve had here have been home-cooked ones.

You know you’ve picked a good spot to eat when you give the taxi driver the address and he knows exactly what you’re up to. “The place to eat crayfish!” he’s likely to say enthusiastically.

It all started about six years ago, when Cretan cuisine – food from Crete, one of Greece’s largest and most famous islands – became fashionable in Athens. Suddenly, Cretan restaurants started popping up all around the city.

Boat-spotting on the Bosphorus is a favorite pastime for those lucky enough to have windows with the right view. On any given weekend afternoon on the busy straits that divide this city, the ship and boat traffic unfolds like a caravan of the flags of the lesser-known countries of the world.

To Triantafilo tis Nostimias restaurant would be impossible to find if someone didn’t tell you it was there. Although just a five-minute walk from busy Syntagma Square, it is hidden in an arcade on the rather unappealing Lekka Street. Despite the central location, the downtown Athens standout remains largely unknown and is not even included in most Athenian food guides. You truly have to be a local to come here.

In many parts of the world, sweet red vermouth is assigned a supporting role on the liquor shelf, a neglected bit player occasionally dusted off to sing a tune or two. In Barcelona, however, the aperitif has played a starring role for ages, so much so that some places even serve the stuff on tap. That’s right. Vermouth. On tap.
