Simon Woodroffe founded the restaurant brand Yo! Sushi, which became an international business after starting in London.
The chain introduced a visually distinctive conveyor-belt service model to British diners. Customers could take plates as they passed, making the meal both a restaurant experience and a rapid way to display the food. The concept helped make sushi more familiar to a wider British audience.
Woodroffe was one of the original investors on the British edition of Dragon's Den. His career is therefore linked to both the programme's launch panel and a recognisable hospitality brand. The company later expanded beyond its first London location and became known as Yo! Sushi in several markets.
The question asks for the founder, not the restaurant style or the name of the television show. Other original Dragons built fortunes in different sectors, but Woodroffe is the investor specifically associated with Yo! Sushi.
