While traveling through subways in Kyoto, I noticed a grocery store in the Zest Oike underground mall.
There is a broad selection, including lots of fruits wrapped in plastic (I’m not used to seeing that). I was drawn to their ready-made to-go sushi boxes.
This was actually really tasty, and the roe was fresh (didn’t know what to expect since it was sitting pre-made). It was better than some sushi restaurants I’ve had in the states lol.
