The name of lunch box -- "Kyo no Obanzai"

When I came back to Tokyo from Osaka, I bought lunch box at Shin-Osaka station.
The name of it is "Kyo no Obanzai".

I think "Kyo(京)" means "Kyoto(京都)" but did not know the meaning of "Obanzai".
According to my checking, "Obanzai" seems to mean "side dishes" that has been used in Kyoto.

I lived in Kyoto about 30years ago but the materials, taste etc. seem to be the one of Kyoto, in fact.

In Shinkansen, you can feel Kyoto if you buy it !!
