Crolla (pictured left) owns the Vittoria Group in Edinburgh, and was recognised with the honour for his promotion of Italian food, drink, culture and heritage through his work with local communities and projects within hospitality.
He was awarded the honour on 9 May at Edinburgh's Stockbridge Church by Italy's ambassador to the UK, Raffaele Trombetta (pictured right), in the presence of Fiona Hyslop, cabinet secretary for culture, tourism and external affairs.
Carlo Perrotta, Italian consulate general in Edinburgh, said: "The Ordine della Stella d'Italia or Order of the Star of Italy is conferred upon individuals who have made a positive contribution to the promotion of Italy and co-operation with other countries.
"Mr Crolla has been given the award for his entrepreneurship and for helping many young Italian nationals arriving in Scotland for the first time with employment opportunities," Perrotta added.
Crolla said: "I'm very privileged to accept this award and distinctive title from the Italian government - it's very special and gratifying.
"I must also take this opportunity to thank my family for their continued support and commitments over the years, our wonderful staff and suppliers who have helped my family build a business we are proud of, and of course the thousands of customers who support us across all our venues, enjoying the hospitality we are famous for."
Crolla was born in Edinburgh and has family roots in southern Italy. With his family he owns the Vittoria restaurant group, which has four sites in Edinburgh, including Vittoria on the Bridge, Vittoria on Leith Walk, La Favorita and Divino Enoteca.
They also own and operate the La Favorita delivery business, with shops in Morningshide, Leith, Portobello and Blackhall.
Crolla's father, Alberto Crolla Sr, opened the family's first restaurant, Vittoria on Leith Walk, in 1970. The company now employs more than 250 staff across its restaurant and delivery sites.
