Lowry executive chef Andrew Green is leaving the Manchester hotel to launch a new venture elsewhere in the city.
Green will remain with the hotel for a few months before taking the role of executive head chef at Mamucium restaurant, bar and café. The Lowry is currently recruiting for a replacement.
The chef earned two AA rosettes for the five-AA-starred, 165-bedroom hotel's River restaurant, having worked there for the last three years.
He previously worked as executive head chef at the Radisson Blu and Crowne Plaza hotels at Manchester Airport, and was last year shortlisted for The Caterer's Hotel Chef of the Year (fewer than 250 covers) Award at the Hotel Cateys.
He said: "I'm really excited about the opening of Mamucium and the new opportunities it will bring. I am looking forward to the challenges ahead and looking forward to adding another exciting and premium dining destination to the Manchester scene."
James Houlston, managing director of BH Group, the developer behind Mamucium, added: "We are so pleased to welcome Andrew to our team. His food is second to none and his passion and authenticity for local and seasonally sourced food complements our vision of Mamucium perfectly. He was undoubtedly the ideal chef for this venture and we cannot wait to introduce his creations to diners in the city."
Designed by 3DReid, Mamucium's interior is described as a "luxurious setting with Art Deco influences".
