Lewis, who started this month, takes the role of head of brand and marketing for the Whitbread-owned pub restaurant chain. He described his appointment "an interesting and exciting new retail marketing challenge".
He left Wells & Young's in May last year, after a five-year stint during which time he oversaw a new advertising strategy for Bombardier beer.
Prior to that, Lewis worked for Carlsberg as a marketing controller and has also held marketing roles at Weetabix, HP Bulmer and Colman's.
