When we emerged from the subway to the promenade of the Olympic Green, I wanted some coffee. There were a couple of convenience stores near the exit, but no hot coffee. We walked further: a ticket office with cold drinks, but no coffee. The promenade was lined with kiosks selling cold drinks and sausages, but no coffee. Eventually we settled on the most popular drink in the place, which was yogurt out of a pot (see the photo).
We saw many families out together: parents, child, and one or two grandparents. Often one of the adults could be seen carrying a big bag of food. The drinks would come from the kiosks.
Over the next few days we discovered that this was one of the differences between Shanghai and Beijing. Shanghai has coffee everywhere, but the main tourist spots in Beijing have no coffee. In this Beijing is more representative of China. Coffee is largely imported, and costs much more than tea.
