In 2015, Ella and her business partner, Matthew Mills, opened The MaE Deli, Seymour Place, Marylebone. In 2016 they opened their second site, The MaE Deli, Weighhouse Street, Mayfair. In early 2017, a third site was launched named The Kitchen Counter, in Herne Hill, as an extension to their development kitchen. In March 2018, after less than a year, the Herne Hill site was closed down, as was the Marylebone deli, due to debts accruing of £720,000.
