When Yo! Sushi arrived in the UK in 1997 it was everything casual dining wants to be in 2019. Colourful, fun, innovative and fresh, it also had entertainment on the side thanks to the novel kaiten conveyor belt that served up plates of food. Remarkably, the novelty hasn’t worn off, even after 22 years. Yo!, which dropped the ‘Sushi’ from its name in September to send a message to the squeamish that it offered more than just raw fish, reported a UK sales hike of 5% to £88.9m in July.
