The company will open a site at 2 New Row in Covent Garden following a successful launch in Oxford earlier this year.
The new site marks the brand's first central London location, a milestone in its ambitious growth strategy to open 100 sites in the UK in the next five years, with 10-15 earmarked for this year, and 3,000 stores worldwide before 2030.
"We are excited to provide visitors and locals to Covent Garden a comforting treat in the form of a delicious hot or cold chocolate drink - to add to their memories whilst exploring the hustle and bustle of the city, or as a welcome break in their working day," says founder Jens Knoop.
Knoops, which specialises in hot chocolate, with a menu of 21 different chocolates, currently operates six venues in Oxford, Brighton, Rye, Kensington, Chelsea, and Richmond.
