Since I already were in Kyoto I went back to the Bon Bon Café and got some more The Eccentric Family pictures.

This time it was open so I got some pictures inside.

It's a regular café and not a pool hall in real life.
You can see this bar to the top left in the anime screen above though even if it's not in the same spot.

I also got a picture of this location near where I stayed in Kyoto. You can also see the Teramachi Shopping Street right ahead. I've marked the path from the café to the 7-Eleven to the right in this picture in the map below.

Teramachi Shopping Street is where Yajiro turns into the false eizan electric railway car. And it's where the Gamers shop in Kyoto is located as well.
These locations wese visited on 2015/11/05.
