In 1930s, "Kai Commander" Western Restaurant was opened on the ground floor of the apartment building where Zhang Ailing, a female writer, lived on Hurd Road (now Changde Road), and opened a branch in the east of Jing 'an Villa on Jing 'an Temple Road, dealing in German cuisine and cakes. Although it is a western restaurant, it also sells coffee in the afternoon. Because coffee shops and train seats were quite popular at that time, and "Commander Kay" western restaurant was a western seat instead of a train seat, the coffee business in the afternoon was not so good. "Commander Kay" western restaurant has been moved to Nanjing West Road several times.

In Shanghai, the afternoon tea of Commander Kay is of good quality until now. Lipton lemon black tea, which is thick and sweet in "Commander Kay", is the fist product of "Commander Kay". It is a perfect match with chestnut cake and cheesecake. It is sweet but not greasy, with endless aftertaste in the mouth, and it can continue tea. From the window on the second floor, you can see the bustling Nanjing Road and pedestrians, which is really a good scenery. The lingering fragrance of black coffee and black tea in the lobby makes people feel lingering.

"Commander Kay" is a place where local "gluttonous men" often meet, and there are few men and women in love. The chandeliers, tableware, tablecloths and napkins printed with the English letters "Commander Kay" are still the previous styles, reflecting the antiquity of the 1920s and 1930s everywhere. Even lazy waiters, if you don't call them, they will always stand far away in the "Gashan Lake". But when you wave, they will soon appear beside you.

After the afternoon tea, "Commander Kay" western food began.

Commander Kay's chestnut cake tastes good. Chestnut cakes in other places are just some chestnuts piled on top of cream, but Commander Kay is an authentic chestnut milk cake. The real chestnuts are covered with thick milk, which looks simple but tastes solid and long.
