Opening at 78 Fetter Lane, the menu will include K10’s most popular dishes such as chicken katsu curry and sushi, alongside newer items ranging from poke to bao buns and udon noodles.
K10 was founded by Christopher Kemper, a former development director at YO! Sushi, in 1999.
It operates two sit-down London restaurants, and has launched two dedicated takeaway sites in the past year.
The group is also behind Beer & Buns, the Japanese craft beer and hirata buns concept, which runs above its Broadgate restaurant.
The new opening comes after Reuben Todd joined K10 as operations director from Patisserie Valerie in November.
A growing number of restaurant brands including Clockjack and Bite Me Burger Co have turned to delivery or takeaway-only sites as a means to expand without the costs of running a full-service restaurant.
Speaking to BigHospitality in 2015, a K10 spokesperson said the group had its eye on further growth in the capital but was put-off by 'crazy' premiums and rents.
They added that K10 eventually hoped to open outside London, and had attracted interest from overseas.
