This project was created during my time as a student in Kyoto University, where the most important thing about the coffee was how much ¥ it was going to set me back. Also can we agree, aren't coffee prices going a bit too far these days?
Special thanks to Paul Anderson, who apart from being a great friend, is also a very good programmer and helped greatly with this project.
Made with ☕ and ❤️ in Kyoto
