Open for lunch from 11-3pm Monday to Friday, the site offers new menu items such as hirata steamed buns, poke and freshly squeezed juices.
Diners can also order K10’s most popular dishes including chicken katsu curry; yakisoba; and fresh sushi.
K10 was founded by Christopher Kemper, former development director at YO! Sushi, in 1999 and has since grown to three restaurants in the City.
The group’s Minster Court site features the longest sushi conveyor belt in the UK, carrying 300 plates around the restaurant in seven minutes.
A representative for K10 previously told BigHospitality the group was looking to open further restaurants, but had been deterred by ‘crazy’ London rents.
Rotisserie chicken brand Clockjack and the Sethi family’s JKS Restaurants group have both launched delivery-only kitchens in the past year as a means to expand without investing in an additional site.
