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.

[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.

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.
