Kioku Bento: Perfect for an Express Lunch in London 

Kioku by Endo is a Japanese restaurant in The OWO, in Whitehall, offering Japanese bento boxes at lunchtime from Wednesday to Saturday.

This curated Japanese bento experience from Executive Chef George, Head Sushi Chef Shibata San and team, balances tradition and modern London dining, served in traditional bento boxes from Japan. Our lunchtime Kioku bento features highlights such as chirashi sushi, delicate chawanmushi, and your choice of main.

Our Bento Menu

Bento is refined in its simplicity, with carefully chosen components presented with precision. Our bento menu may evolve with the seasons, guided by availability and freshness.

Chirashi Sushi 散らし寿司

Chirashi sushi is a traditional Japanese dish of seasoned steamed rice topped with assorted fish and garnishes, as well as tamago, soy, and wasabi for balance and freshness.

Chawanmushi 茶碗蒸し (v)

Chawanmushi is a delicate savoury egg custard, lightly steamed, with the addition of mushrooms, green beans, and carrots, making it comforting in texture with a subtle umami flavour.
