Which original Dragon was the founder of the Yo! Sushi restaurant chain on Dragons' Den?

Simon Woodroffe was the founder associated with the Yo! Sushi restaurant chain and was an original Dragon on Dragons' Den.

Yo! Sushi opened in London in 1997 and became known for its conveyor-belt presentation of sushi and other Japanese dishes. The concept made the food highly visible to customers and created a distinctive, fast-moving restaurant experience.

Woodroffe’s wider career included hospitality and hotel ventures, including the YOTEL brand. On Dragons' Den, his experience was rooted in building memorable consumer concepts rather than in traditional manufacturing alone. The restaurant name is commonly styled as YO! Sushi, while general references often use Yo! Sushi; both identify the same chain.
