Wasabi, the sushi and bento chain led by Dong Hyun Kim, has opened an updated version of its concept on the site of the former Mash Tun pub in London’s Victoria Station. The group, which operates a further 19 sites in the capital, previously ran a mobile unit at the station just outside the pub. The new site features a more update-to-date and brighter look for the chain and includes outside seating on the station’s concourse. Earlier this year, the group, which also operates the Kmichee restaurant in High Holborn, reported a 27% rise in turnover to £22.97m for the year to 31 August 2010, a period that saw the group almost double the size of its estate.
