We’ve been fans of the authentically spicy flavors of La Wei Xian since 2014, when we added the ramshackle restaurant to our Night Eats tour route in the Laoximen neighborhood. The stop was a favorite of our guests for years, but in August 2017, Mr. Liu fell victim to the redevelopment of the Old Town area and was forced to shut down his shop when the local government wouldn’t renew his food and beverage licenses. But Mr. Liu has never been one to give up, and he’s always got his eye on the bottom line. He is the type of guy who will spend hours trying to convince you to go on a four-day road trip with his whole family (totaling six members) back to his hometown of Zigong, Sichuan, in a Winnebago that is meant for two at best, just to split the gas money.

The relative abundance of heritage architecture and mixed zoning in the former French Concession neighborhood (technically the Xuhui district) has left a legacy of nooks and crannies where a number of mom-and-pop noodle shops are able to withstand the test of time and pressures of a fast-changing economy. Luckily, enough noodle lovers are still craving the classics and will queue up to support their favorite local haunts. Our top five picks can get crowded, but if you avoid the main lunch rush from noon to 1 p.m., you shouldn’t have to fight (too hard) for a seat.

Sichuan cuisine is famous for its mouth-numbing, spicy flavors, but what many people don’t know is that the provincial cuisine is subdivided into several specialty subregional cuisines. One of our favorites is Xiaohe Sichuan cuisine, which hails from the cities of Zigong, Luzhou and Yibin in the province’s southern region. Originally famous for its salt mining, the Xiaohe (which means “small river”) region is now perhaps best known for the Zigong Dinosaur Museum, a monumental museum built over a dig site that’s had an incredible number of dinosaur finds. But the local cuisine – renowned for being spicy and creative – is worth exploring.

In Shanghai, robot restaurants (and grocery stores) were all anyone could talk about in 2019. Well, that and bubble tea shops. But we love that there are still thousands of mom-and-pop restaurants serving traditional foods that are handmade and well loved, if you know where to look. So next time, skip that trendy, US$100-a-head hotpot joint where you still have to queue for an hour after your reservation has passed, and try your local noodle joint. Of course, you’ll probably scan the QR code on your table to order (and pay), and you won’t even chat to the staff until they put your dishes in front of you – after all, it is 2019 in one of the most tech-forward cities in the world.

Colonia Juárez – our 2019 “neighborhood to visit” in Mexico City – was a forgotten district for many years, known more for its karaoke bars and strip clubs than its charming plazas or cafés. Originally founded as an illustrious upscale neighborhood for the city’s industrialists, the area saw an influx of Asian immigrants mid-century, abandonment after the 1985 earthquake, and then fame as the city’s LGBTQ hangout in the 2000s. Over the past decade, the neighborhood has been turned upside down – newcomers are clamoring for a chance to reside behind one of its gorgeous French architecture facades, and restaurateurs, having taken note of Juárez’s rising popularity and its unique mix of old and new, are flocking to the area. Like the hood itself, the best off-the-beaten-path places include a little of the traditional and some new strokes of genius. Here are some of our favorites.

In Beijing, it’s not uncommon for a waiter to ask “有忌口吗?” before you start ordering. It translates as “Anything you don’t eat?” With a large Hui Muslim minority population, Beijing is more accustomed to diners with dietary restrictions than southern cities like Shanghai. In the Paris of the Orient, it’s not uncommon to explain that a diner is vegetarian and still have their tofu or vegetable dishes come out of the kitchen sprinkled with minced pork. The common retort when pointing out the meat is “It’s just a little bit – for flavor!” But Spring Trees takes that northern dietary accommodation a step further, offering meat-free renditions of classic Sichuan dishes alongside the pork-laden options. It’s perhaps the best option in Beijing for diners looking for a pork-free (or fully veg) restaurant.

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.

When a menu is written only in Chinese characters, it presents a language barrier for foreigners. When a restaurant offers a Mandarin-only menu and requires diners to handwrite their order in characters, that molehill becomes an actual mountain. But Zhang Mama doesn’t care – diners have been queuing up for upwards of an hour outside the dingy hutong restaurant for a bite of its Sichuan cuisine since it opened in 2009. Why? It’s equal parts delicious and cheap. Demand got so high for this hole-in-the-wall shop that they opened two more shops, one just down the street from the Dongcheng district original and another in Chaoyang district. But it’s still not easy to get a seat during peak mealtimes.

“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.

[Editor's note: We're sorry to report that Bamboo Sichuan has closed.] The temperature has officially fallen off the register, and there are days when Shanghai seems bleak indeed, the cumulus clouds of winter hugging the skyline uncomfortably close.It’s times like these when we look to western China for inspiration, and nothing but Sichuanese-style roasted fish (四川烤鱼, sìchuān kǎo yú) will do to lift the spirits and drive away the bleary stagnations of cold, wet weather. This dish is common in Chengdu, the heart of Sichuan and an undisputed food center of the Middle Kingdom. Located in the Red Basin and hemmed in by imposing peaks that wander towards the Himalayan foothills, this cheerful culinary capital – much like Shanghai – in December boasts an icy humidity that seeps into the joints and refuses to leave.
