Wasabi, the London-based sushi and bento chain led by Dong Hyun Kim, plans to operate an estate of around 40 sites by the end of this year, while turnover in its current financial year is expected to reach £45m.

The group, which will open its first international site in New York in June, will open in South Kensington at the end of next week, with a further site in Wardour Street to follow. Spend per head across the group is on average £6.95.

The chain, which was founded in 2003, has two openings lined up for the Trinity development in Leeds.

It is also thought to exploring opportunities in Dubai, Italy and France.
