Café on Air is a classic hidden coffee shop and perhaps Shanghai’s best coffee shop overall. The natural and electric lights create a warm interior, the design is great and the coffee is beautifully made. It’s also really central, close to the subway, and not that difficult to find, as far as hidden coffee shops (yes, it’s a genre) go. Still gets crowded despite being tucked away, but it’s free of the buzz of Huaihai Lu, and reminds you of all of the hidden history in the city.
