Chen Danyan's "Coffee is bitter" has a chapter written in Vienna's Schwarzberger cafe. So during his three days in Vienna, he took an afternoon and went to Schwarzberger cafe with a pilgrimage. After a half hour of navigation, I finally saw Schwarzberg Cafe, the brown-red sunshade, the menu on the piano shelf, the lazy guests in the open-air seats, and the other cafes in Vienna, except for the 1861 mark on the wall. Pushing open the heavy door, seeing two long strips into a right-angle store hall, a bar at the corner, surrounded by a high wall panel, arched roof, old-fashioned ornate ceiling, semi-circle chair, and a feeling of déjà vu. Shanghai's old bungalow? The similarity needs to be verified. Drinking bitter coffee, eating sour Sach cake, in the early spring sun, Kafka, Mozart, etc. came to my mind, and there were all the cakes on the scale, and concluded that no matter what was stronger than the Sach cake that the Austrian emperor liked. Hey! Food is food, there is no way to install literature.
