等一個人咖啡 Cafe.Waiting.Love
In the photo is strawberry milk.
Cafe waiting Love is the name of a movie. It's about a woman who opens a cafe (with the same name) just for waiting her past love. And the main character who is a coffee maker tries hard to make the same coffee as the past love did.
So the best seller in the cafe is 老闆娘特調 (kind of coffee) which is the one the owner is looking for!
Here is the original cafe where this movie took place:
台北市文山區一壽街44巷1號
