In the UK television show Dragon's Den, which original dragon founded the company Yo! Sushi?

Simon Woodroffe founded Yo! Sushi and was an original dragon on the UK television show Dragon's Den.

Yo! Sushi is a British restaurant chain associated with conveyor-belt service, allowing customers to select dishes as they pass their table. Woodroffe founded the business in London in 1997, bringing a highly visible Japanese-inspired service model to the UK restaurant market.

Woodroffe later joined the first Dragon's Den investor panel when the BBC series began. His entrepreneurial identity was tied to hospitality and consumer-facing businesses, while the programme itself focused on founders seeking investment.

The restaurant's name is sometimes written with punctuation as “YO! Sushi.” It should not be confused with the show's Japanese source format, even though both the restaurant concept and the television format have Japanese associations.
