Intro
A stylish cafe located a short walk from the station, which opened recently. Within a week of opening, it has already become a popular shop with long lines. However, even a cafe like this has its quiet hours.
Come to think of it, this place had a huge line the other day... Maybe I'll try going in... (It is now around 2:00 PM, past the lunch rush, and the shop is quiet.)
