Missed this place the first time I dropped by J-Town. When you enter the grocery store, turn to the left and walk straight to the very end and then through a door and you end up at Sasaki. I went close to closing time and they only had the black sesame and Sakura ones left, so I got one of each.
The texture of the mochi is amazing. It was soft and not overly chewy. The filling was light and not too sweet either which I prefer, as it allows me to eat more. :) Both flavours had a hint of whipped cream like filling in it mixed with the flavour paste. Each piece is around two or three bites, so not recommended for sharing. :P
