In fact, if you don't bother to go out, I suggest going to Xinqiao Sanbaole. His cakes are super authentic and delicious. There is one in Chongwenmen and one in Fangzhuang Guiyou.
In fact, Maxim's cake is the best ~ Compared with western restaurants, his cake is really cheap and really delicious ~ ~ I strongly recommend trying it ~ ~ It's also in Chongwenmen.
