Fusian’s business has expanded from sushi rolls to toilet paper rolls in the last few weeks.The Columbus-based fast-casual restaurant chain made one of the more interesting business pivots amind the Covid-19 pandemic. It started a grocery delivery business, turning all 10 of its Ohio restaurants into mini-distribution hubs hoping to bridge a small gap for consumers struggling to find a few essentials.Now, in addition to its menu of sushi rolls, as well as some meal kits that also are new to the business, Fusian is selling and delivering items like produce, milk, eggs and, yep, even toilet paper. It’s also bringing in other area businesses to join it, like the Lox Bagel Shop in the Short North.Co-founder Stephan Harman sat down with Columbus Business First to discuss that thought process, how it is performing in the past two weeks and whether or not it has a future in the Fusian business model.
