Simon Woodroffe was the original Dragon's Den investor known for founding the Yo! Sushi restaurant chain.
Woodroffe created Yo! Sushi in London in 1997. The restaurant became known for serving sushi from a conveyor belt, a design that made the food highly visible and helped make the dining experience distinctive. His entrepreneurial career also extended into hospitality and other ventures.
He was part of the first UK Dragon's Den investor panel alongside Peter Jones, Duncan Bannatyne, Theo Paphitis and Rachel Elnaugh. Woodroffe later left the programme, so he is associated with the original line-up rather than the long-running later panel.
The question identifies Woodroffe through his business background, not through a product pitched on the programme. Yo! Sushi is often written as “YO! Sushi” in the company's branding, but Simon Woodroffe is the person connected with its founding.
