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.

The promise of food prepared before our eyes, just for us, is a big reason that we’re constantly spreading the good word about food events in and around New York. We’re especially fond of festivals and other gatherings held by members of a close-knit group – sometimes congregants of a church, temple or mosque, almost always folks who share the common bond of a previous homeland far away. Often their dishes are assembled by (gloved) hand immediately before serving for maximal stimulating freshness. A few such events repeat periodically, but most, we know all too well, come just once a year. We’re always on the lookout, then, for businesses that take a similar up-close-and-personal approach.

These days, you won’t find anyone reaching for their wallet while dining out in Shanghai. Cash has become almost obsolete as virtual currencies corner every last slice of the retail payment market. QR codes and app-based systems are the new normal, even for transactions less than the equivalent of US$1 (like our beloved breakfast street food staple, the jianbing). According to a recent New York Times article, mobile payments in China hit US$5.5 trillion in 2016. Yes, with a “T”. And 2017 is sure to be another banner year as AliPay, WeChat Wallet, Apple Pay and others continue to fight for market share.

The road from Nepal to Portugal might be a long one, but in recent years it has become surprisingly well trafficked. Since 2006, the Nepalese presence in Portugal has grown by approximately 400%, concentrated in particular in the metropolitan area of Lisbon, part of an Asian community that in relative terms is the fastest growing in the city. A tight-knit community, the Nepali immigrants often find work through compatriot networks, providing each other with mutual support as they settle into life in Portugal. The food industry in particular is an important gateway into local economic life, with Nepalese-run restaurants, groceries and mini-markets now dotting the Portuguese capital.

Whether we’re heading to Sichuan province for a little culinary vacation or just looking for the best bowl of dan dan mian in the city, there’s one person we call for dining recommendations: Jenny Gao. Born in Chengdu and raised in Canada, Gao’s family still lives in Sichuan, and since moving to Shanghai in 2012, she visits them often. Over the past couple years, she’s turned her love for her hometown cuisine into a full-time job, becoming Shanghai’s unofficial Sichuan food ambassador. For years, Gao was the writer behind Jing Theory, a popular food blog about Shanghai’s best places to eat, drink and more.

In the past year, we’ve seen more new noodle houses hawking spicy Chengdu and Chongqing style noodles than we can count on two hands. Very few of the Shanghai-based noodle houses do the fly restaurants of Chengdu justice. Some dish out bowls of insipid strands that barely register on the Scoville scale, while others go for that unbalanced, burn-your-face-off flare that means the chef has likely never been to Sichuan, much less studied the careful art of the region’s balanced cooking. Liu Dao Men is among the exceptions, carefully walking the tightrope of spicy yet tasty, with its menu of Chengdu noodle classics.

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.

It’s an unseasonably warm winter day as we make our way through the residential backstreets of Higashi-Shinjuku. Drying laundry hangs on nearly every balcony of the low-rise apartments beneath a cloudless, blue sky. The streets are nearly empty, but rounding the final corner to our destination we join a stream of people from all four points of the compass congregating in front of the Tokyo branch of Nagoya-based maze-soba shop Hanabi. The story of how this particular noodle dish came to be is a winding one. In the 1970s, the Taiwanese chef Meiyū Kaku was living in Nagoya and missed a few choice flavors from home.

Shanghai's dining scene was abuzz with controversy this fall as the Michelin Guide landed in the city for the first time ever. You can't please everyone, but no one seemed happy with the disproportionate number of Cantonese restaurants that were recognized. Thankfully, there's still plenty of delicious variety in the city, starred or not, and we continued to chow down across the price and regional spectrum.  A Da Congyoubing After 34 years of making the cult favorite scallion oil pancake, Mr. Wu was shut down by the government in September for not having the proper licenses. Thanks to the serious outcry from the city’s foodies, the district government helped him expedite his licensing, and delivery start-up Ele.me found a new spot just a couple blocks from his apartment.

Anticipating a line, we arrived ahead of our appetite, but the slightly acrid smell of fresh dashi wafting over the street hurried our hunger. Tucked behind a handful of confounding corners southwest of Shinjuku Station in a mixed-use neighborhood of apartments, shops and offices, Udon Shin has consistently ranked among the best udon restaurants in Tokyo since opening in April 2011. At around ¥1000 (US$9) per meal, you feel like you're getting away with something. Owner and chef Shinji Narahara deftly handles the classic accompaniment to udon (think homemade dashi, deep-fried tofu and tempura) but elevates the humble noodle to modern heights with their trademark carbonara udon.

“Can you eat spice?” the waitress asked after taking our order. Her hand hovered hesitantly over the cash register. “Yes,” we replied. “But... Can you?” she asked again, looking to the other waitresses for help. “Yes!” we responded emphatically, trying to vocally convey our love of the tongue-tingling, lip-burning action we had come for. “Umm... These are Chongqing noodles. They are really spicy,” she said with her hand still in a no-man’s-land somewhere between our money and the cash register, unsure whether our foreign palate had what it took to slurp down a bowl of noodles from China’s spiciest city.

When you’re in the capital of Sichuan province, snacking is a way of life. Noodles made of bracken, wheat, chickpeas, mung beans and more, as well as tofu puddings and dumplings, make up the city’s “small eats” (小吃, xiǎochī) scene, served from what’s colloquially known as “fly restaurants.” A step above street food, these family-owned eateries are so called because they attract diners like flies, despite what might seem like a less-than-hygienic atmosphere, because the food is too good to miss. Find a hole-in-the-wall that has more diners than stools, and order one of these local specialties for a delicious meal.

Healthy eating and Chinese food are often hard to combine, but Karen Chen has discovered the recipe. After the success of Jianguo 328 (a homestyle Shanghainese restaurant that forgoes MSG and uses filtered water to boil its excellent noodles), the Taiwanese restaurateur decided to look west – where spice is king – for her next venture: Yi Zhang Hong. The friendly Sichuan restaurant is cobbled together with a narrow staircase leading up to cheerful dining rooms over three floors. On each level, bright folk art hangs on white walls above long banquettes and blond wood tables, and the red-tiled bar on the first floor is decorated with bottles of imported wine and beer and canisters of local tea.

It was Mr. Liu’s huge grin that first caught our eye, welcoming us into his humble, living room-sized restaurant. Scanning the small space, we suspected we had hit upon a gem: white tile walls, basic stools, vegetables crammed into the fridges in the dining room and fiery red dishes dotting the tables of happy diners – all hallmarks of the down-to-earth eateries we’re always looking for. As we sat down and he started explaining his specialties, we could feel his genuine interest in having us taste his authentic Sichuanese cuisine, going well beyond just making another sale.

We crept down an almost unmarked flight of stairs, then through a dim, winding corridor and finally pulled back a noren curtain to find ourselves in the world’s only Ippudo ramen location that serves soba noodles instead of ramen. As we seated ourselves on stools around the U-shaped counter, the aroma of tonkotsu (pork bone) broth reached our sinuses and informed us that we had arrived in a place like no other. Shigemi Kawahara opened his first Ippudo ramen shop on the southern Japanese island of Kyushu in1985 and over the next 15 years became a revered ramen master by winning numerous ramen championships on TV.
