Wasabi has appointed Raoul Federman, formerly of Aubaine, as its new group finance director, MCA understands.
It follows the departure of Scott Etherington, who is understood to have left the sector.
Federman was most recently interim finance director at Vital Ingredient. He previously spent three years at Aubaine before leaving as part of a management restructure.
In its most recent financial results, for the year to December 2016, the sushi and bento chain grew like-for-like sales 8.1%, with turnover growing 21.5% to £98.1m.
The group opened the first of five sushi counters in partnership with Marks & Spencers in October.
