“Do you remember Saturday Coffee,” our conversation begins. We do, the small cafe on Yongjia Lu that served coffee and warm sandwiches, two blocks from our last apartment in Shanghai. It was open just over a year and then disappeared. A couple’s dream of entrepreneurship hindered by the rising rents and limited clientele. Most of the time we had the place to ourselves, could get coffee and two sandwiches without any wait, which was part of the appeal. Mostly though we liked the owners, and their sandwiches. We liked living two blocks from a cafe in Shanghai.

These are the brief memories of an urban area. In San Francisco we reminisce about Hotei, our favorite Sunset ramen spot in two thousand ten, since closed. For two years we would walk the ten blocks through the early evening fog to have ramen, to be welcomed by the staff accustomed to our routine, and to enjoy the peace of Sunday before the week began. When it closed, in two thousand fourteen, Hotei joined Saturday coffee in our memories, places to be discussed nostalgically.

So much of living is about watching things end, about remembering restaurants no longer open, friends who have moved away. Rare then are the places that have endured, the corner pub, the tiny burger joint. Rare is the other side of these conversations, the acknowledgement of survival, more commonly said with reverence.

“It’s been there twenty years,” he says about the corner store. The owners are friendly, part of the neighborhood. They provide booze to the homeless and coffee to the construction crews, milk to the forgetful and egg sandwiches to the hungover. As neighborhood staples go they’re a highlight in an area that has for so long been neglected by the city. Building this reputation has taken years of opening early and closing late, of hosing off the street outside, of brushing up the trash and adapting the stock to suite the neighbors. Recently the coffee has improved, a nod to the younger generation moving in. They still play KQED and know the baseball scores.

Like Ebisu, Jenny’s Burgers, and the Little Shamrock in the inner sunset, the places that have survived are special too, even though discussing them usually involves commenting on the current state of the city rather than remembering the idealized version of our memories. Saturday Coffee, Boona 2, and a dozen other of my favorite places in Shanghai have shut in the decade since I moved away. More impressive, then, are the places that endure, the woman still cooking noodles on Wuxing Lu, Bar Constellation and People’s Seven, because they have become part of the tapestry of Shanghai by surviving.

The trick to discovering cities is to remember that they are constantly changing, that of course the things we love will disappear. Restaurants shut and neighborhoods turn over not because things are getting worse but because nothing lasts forever. We should celebrate having had those sandwiches, having lived near that bar, and tell tall tales about our luck.

And we should continue to explore, to grow and to discover. Living in a city is a gift. It is lucky to be somewhere that is alive, growing and evolving, to be somewhere that pushes us to do the same.
