The Michelin Guide might have come to Shanghai last year, but the far more interesting trend for budget diners in the city is the fast-casual local restaurants opened by savvy young Chinese with an eye for design and a great palate. The Noodlista is one such shop – just check out its logo. The character for noodles is warped into a downward facing arrow, as if to say, “Get your noodles here!” It’s good advice, and local millennials are taking it: come lunchtime, Noodlista is always packed to the gills with young worker bees from nearby office towers. Showcasing the management’s fluency with both Eastern and Western cultures, English and Chinese coexist happily on the menu.

Mamouniyeh is a lovely semolina pudding that is a speciality in Syrian kitchens, and it can be enjoyed right here in Istanbul on our Kebab Krawl walk.

Getting ready for a recent New Year’s in Harlem, the Hungarian side of the family was craving a traditional pot of lentils that needed a hunk of smoked pork knuckle. Where to find one with the right flavor in New York City? After some calls and searching, we headed out to Muncan Food Corporation. The address brought us to a storefront along a strip of low-rise brick buildings in Astoria, Queens. Inside the front door we were blasted with smokehouse aromas. To the left: racks of sausages, pâtés, cold cuts – all kinds of dried and cured delicacies dangling from hooks overhead.

(Editor's Note: This piece marks the beginning of CB's new section devoted to the food of Queens, New York and the people making it. We plan to file regular dispatches from the borough of global eats.) For many visitors to New York, the first sight of Queens comes from above, during the approach to JFK or LaGuardia, the city's two international airports. And the first thought, upon landing, is to keep going. How far is it, they wonder, to our room, and to the museums, theaters, shopping and sights? How long till we get to "the city"? For culinary explorers, Queens is not merely a way station, it is a destination in itself. The largest in area of the five boroughs of New York City, Queens is the home of well over two million people, half of them born outside the United States, speaking untold hundreds of mother tongues. During the course of a day, you might hear a dozen languages without breaking a sweat.

Walnuts are a prominent fixture in Georgian cuisine, and the best ones can be found in Tbilisi's Dezerter Bazaar, the focal point of our culinary walk in the city.

Rua das Portas de Santo Antão is probably the most touristy food street in Lisbon. This pedestrian road is full of restaurants with guys outside hawking their specials and menus offering out-of-season sardines and frozen pizzas. But there’s more to this downtown thoroughfare than just luring American vacationers to overpriced mediocrity. Located on this road, buzzing even before the tourist boom thanks to its central location, musical theaters and local commerce, is one of the city’s timeless classics, O Churrasco. This restaurant looks different from the usual chicken restaurant, with impressionistic paintings hanging from its wooden walls and waiters in bow ties, and has been a camouflaged gem for many years, a particular favorite of middle-class families and theater lovers.

Avli is one of those places you have to be introduced to by someone who’s already been there. Although a sign does exist above its narrow metal door, there’s so much graffiti on either side of it, you could walk right by even if you had the address firmly in your hand or mind. Once inside, if you’re the first customer, you still might think you’ve made a mistake. Avli means “courtyard,” but this one is narrow, much more like a back alley. Blue doors and shuttered windows the same shade as the Greek flag pierce the right wall, the left has a few potted plants and three plump alley cats comfortably ensconced on the old-fashioned rush-seated taverna chairs.

Istanbul's Kurtuluş neighborhood is home to a number of slow-burners, establishments that may be hidden in plain view due to their plainness but that end up becoming some of our favorites. Gimmicks don’t fly in down-to-earth Kurtuluş, where neighborly ties are strong and home-cooked meals are preferred. Tucked on a side street in the middle of the quarter is a small eatery that exemplifies this tried-and-true character. Behind windows that fog up quickly in the winter sit a handful of tables facing an open kitchen in what might be Istanbul's coziest restaurant, Ben-u Sen, which showcases the divine ev yemekleri (home cooking) of the delightful Nuray Güzel.

For the most part, hamburgers in Mexico City disappoint. The accepted bread-to-beef ratio is shameful, with slender slices of overcooked meat hiding somewhere within the pillowy fluff of too much bread. The stringy, flavorless beef underwhelms. Even worse are the fancy sandwiches one finds at upscale burger joints, where blue cheese and spinach and a dozen other inappropriate ingredients only momentarily distract from the aforementioned defects of bad meat and a surfeit of bread. Against this dim backdrop of underachievement, the hamburgers at the Legión Americana shine like stars. This is something of a surprise considering the no-frills, dive bar atmosphere here.

Like chicken yakitori served alongside cold beer? So do we, which is why we made sure this crucial pairing is among the elements of our Tokyo Time Machine culinary walk.

It’s difficult to imagine a job where a major skill set is eating a vast amount of food and becoming as large as possible. Yet sumo wrestlers, in an effort to bulk up and to be able to throw their weight around in the ring, consume enormous amounts of protein-rich, calorie-heavy meals – primarily in a dish called chanko nabe (a one-dish hotpot) – hoping to do just that. At Chanko Dojo, diners are encouraged to fill up as much as possible as they soak up sumo culture. (For another eatery devoted to wrestling, read our review of this Mexico City spot.)

Among the many enticing culinary attractions of our revamped Crossroads walk in Lisbon include a sampling some of Portugal's quintessential wine and cheese.

Cariocas don’t give much love to Niterói, joking that the only reason to go to this city across Guanabara Bay is for its spectacular view of Rio de Janeiro. But while less busy and far less popular than Rio, Niterói is full of lovely beaches, great museums, excellent restaurants and hundreds of bars. Among the many reasons to visit is Salve Simpatia, a botequim – or small, family-run bar serving snacks to go with drinks – where traditional bar gastronomy mixes perfectly with delicious artisanal burgers, specialty beers and remarkably good music, especially samba. Salve Simpatia (which means something like “Hello, my brother” in Portuguese) opened in 2012 and was known only to locals in the Icaraí area for a while.

Jordi Piquer opened his popular restaurant in 1968 on an auspicious day: April 23, a holiday that honors his namesake saint. Saint Jordi must have been looking down on Piquer and his dedicated customers when the restaurateur decided to sell his establishment in 1986: three trusted employees banded together to buy it, keeping the Sant Gervasi neighborhood institution in business. A fine example of a classic 20th-century Barcelona restaurant, Casa Jordi is decorated in the old masía (traditional Catalan farmhouse) style over two floors but adapted to urban dimensions, meaning that there are fewer intimate corners but larger, more flexible rooms with tables for groups.
