Sometimes a word in Chinese so perfectly captures a mood or feeling that the English approximation seems woefully inadequate. To take one example, the Chinese combine “hot” (热) and “noise” (闹) to describe the loud and lively nature of local hotspots, but in English, the best we can do is “bustling.” To experience what China’s “hot noise” is really all about, head to Wei Xiang Zhai. Not for the claustrophobic or timid, this wildly popular noodle house demands that you elbow your way to a table for your chance to slurp down a bowl of the city’s best sesame paste noodles (麻酱面, májiàng miàn). Don’t be intimidated by the Chinese-only menu here. It may look long and complicated, but over the years, the character for “sold out” (无) has become a permanent menu fixture, collecting dust and reminding diners that once, long ago, there were other options here.

Dining like a local in Shanghai often requires a small leap of faith. You have to forget about ambience and brave tough crowds with even tougher elbows to join the raucous, slurping masses with their steamers of the city’s famous soup dumplings, xiǎolóngbāo. Even with its thriving economy and sky-high construction boom, Shanghai still has a street food culture that is deliciously cheap and easy to find. To become a part of the appetizing fun, just look one street off the main road or wander into the city’s disappearing lilong (里弄, alleyways), which more often than not are teeming with Chinese pancake hawkers, wonton shops or makeshift grills emitting the smoky aroma of charred lamb kebabs.

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.
