Paul Tamburrini's Bistro Deluxe restaurant at the Macdonald Holyrood hotel in Edinburgh will close on Monday to be replaced by the group's new Surf & Turf concept.
Tamburrini, who was previously chef director at Martin Wishart's Honours brasserie, will undertake a six-month culinary research trip to Singapore, New York and Dubai following the closure.
Bistro Deluxe opened in October 2017 following a £250,000 investment. Deputy chief executive of Macdonald Hotels & Resorts Ruaridh Macdonald said the success of the Surf & Turf restaurant at Macdonald Rusacks hotel was a "major driver in the decision".
He said: "We had always intended to roll out the restaurant theme but the very strong demand from customers at Macdonald Rusacks has considerably exceeded projection. This, and the fact that Paul announced he was keen to travel for several months to research new food themes, made it an easy decision.
"Paul is, without doubt, one of the most talented Scottish chefs of his generation and it will be very exciting to see what direction he takes when he returns from his travels."
Tamburrini added: "I have hugely enjoyed the partnership with Macdonald Hotels & Resorts, which has given me the chance to put my own individual stamp on the restaurant and am particularly grateful to chairman Donald Macdonald and Ruaridh for having such faith in me.
"However, after 25 years leading chef brigades, I am really looking forward to experiencing some of the most exciting international cuisine over the next six months and bringing those lessons back to Scotland in the future."
The Surf & Turf restaurant concept will also be extended to the Macdonald Marine hotel and spa in North Berwick under the guidance of executive chef Glenn Roach.
