This is the place to go to taste the best onigiri in London! Masami puts all her heart and talent in each onigiri she makes. They are full of flavours and are a delicacy. You can taste that all the ingredients used are top quality products. She even offers new seasonal onigiri depending on the season. You should also taste the miso soup. It’s the best!

Delicious onigiri and amazing service from Masami and Christophe. The flavours are outstanding, our favourite are the tuna mayo and kombu. Since we moved away from west London we have missed them dearly and always look forward to coming back. A must visit if you are nearby and well worth travelling for if you are not.
