It follows reports last month that the 105-strong Italian chain had approached private equity buyers in a bid to secure a sale.
Now the group has launched a 3,000 sq ft restaurant and deli at the London Marriott Hotel Maida Vale.
Carluccio’s is responsible for all the food and beverage operations at the hotel from this month, including room service, conferences and events.
The 146-cover Maida Vale restaurant has its own separate entrance and features a lounge bar, outdoor terrace, retail area and deli.
Carluccio’s CEO Mark Jones says the group, which has opened at Marriott properties at Heathrow and London's Regents Park since 2016, is “particularly suited” to hotels.
Hotel groups are increasingly turning to established chains to handle their food and beverage operations. Both Jamie’s Italian and Aubaine have opened in Hilton sites since 2014.
The news of Carluccio’s expansion off the high street comes in the wake of reports that the chain, which was sold to Landmark for £90m in 2010, has approached turnaround specialists and private equity groups, including Wagamama owner Duke Street, over a possible sale.
Accounts show revenues at Carluccio’s rose 2.7% to £140m in the year to September 2016, but pre-tax profits dropped from £5.2m to £982,000.
