English words are too common, so they started using French worlds.
There are so many cafes and restaurants in Tokyo people never remember the names of.
For example, there is a nice French restaurant called "4em". Their customers don't know how to read it, but the restaurant is busy.
And not far from 4em, there is a cafe called, Quatre Vingt Neuf (89). Nobody remembers the name. But it is also full.
Here, the French language is not used as a communication tool. It is used as part of the design. So, it doesn't really matter if people remember the names or not.
On this photo, it's something I found few days ago, Café à la papa.
At the moment, it is a big mystery for me, why they use the name, and what kind of food or drinks they serve!
