Which investor was known as the founder of Yo! Sushi on the British series Dragon's Den?

Simon Woodroffe was the investor known as the founder of Yo! Sushi on the British series Dragon's Den.

Woodroffe founded Yo! Sushi in 1997, introducing a conveyor-belt restaurant concept to Britain. The business became notable for serving sushi from a moving conveyor, allowing customers to select dishes as they passed their seats.

He joined the original investor panel when Dragon's Den began in 2005. His background differed from that of some later dragons because he was particularly associated with hospitality, restaurants and entrepreneurial design. He subsequently left the regular panel after the first series.

A common mix-up is to associate Yo! Sushi with Theo Paphitis, another prominent British entrepreneur who later became a dragon. Paphitis is best known for businesses including Ryman and Robert Dyas, whereas Yo! Sushi is specifically linked to Woodroffe.
