A thing I really love about Japan is the way that you find restaurants. Take this door for instance. Looks like a tiny door leading to either nowhere or a tiny space. However, I learned that these seemingly tiny places can be humongous once you go in and downstairs.
I find this interesting – you dont see what you get into before you actually walk downstairs. In good old western tradition, I was searching for restaurants where I can see what going on, check the ambience, if it looks cozy… well, not in JP!
