Like Atatürk statues and crescent-and-star flags etched into the sides of mountains, the öğretmenevi (“teacher’s house”) is an integral part of the Turkish landscape. Found in almost every city in Turkey, these government-run institutions serve as affordable guesthouses for educators on the road and – since anyone is welcome if space is available – for those traveling on a teacher’s budget.

Greece has a fantastic tradition of pie-making. Most Greeks have memories of their granny making some sort of pie in a big pan for the family to share. Savory pies are sold in individual portions in bakeries (which are everywhere in Athens) and sandwich shops, or even whole and frozen in supermarket freezers, much like pizza is sold in the U.S.

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.

[Editor's note: We're sorry to report that A Da Cong You Bing has closed.] In China, where queuing isn’t part of the culture, a long line of hungry diners patiently waiting for their food is just about the highest compliment a restaurant can receive. By those standards, Mr. Wu’s scallion oil pancakes are, hands down, one of the most sought-after breakfast treats in Shanghai. The line that stretches out his kitchen’s back door and wraps around the street corner means that fans of his savory pancakes can wait for hours, gulping in the scallion-scented air as they look forward to their chance to sink their teeth into the real thing. Scallion oil pancakes (葱油饼, cōngyóubǐng) are a common breakfast treat in Shanghai, but when Mr. Wu makes them, the little savory rounds stuffed with salty pork and scallions become an art form.

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.

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.
