The co-founders of Cubitt House, the upmarket pub and hotel operator, are planning to launch a new Italian restaurant in London’s Marylebone, M&C Report understands.

Stefan Turnbull and Barry Hirst have joined together with Marcello Bernardi and his brother Gabriel, the London-based interior designer and Cubitt House co-founder, to develop Bernardi’s, which they hope to launch at 62-64 Seymour Street.

It is thought that the new joint venture is set to invest c£1m to develop the site, which will feature an all-day offer aimed at a variety of different needs, including a brasserie-style breakfast, weekend brunch, casual lunch, business lunch and Cicchetti.

The food will be “light, fresh and seasonal” influenced by “honest and rustic Italian regional simplicity”.

There will be a restaurant/brasserie on the ground floor, while the lower ground floor space will have more of a “lounge bar vibe” and include dedicated spaces for tailored-made events.

The partners plan the offer to be “proudly not a chain, exceptionally well designed and not overtly Italian”.

The team behind Cubbit House is set to open to new restaurant and bar venues next year as part of a sister operation.

The first will open early next year Fitzroy Place, W1, while a second will open in Granary Square within the Kings Cross redevelopment in London in mid-2015.

Cubbit House currently operates a leasehold estate of four upmarket West London pubs and hotels – The Orange on Pimlico Road, The Grazing Goat on New Quebec Street, The Pantechnicon on Motcomb Street and The Thomas Cubitt on Elizabeth Street.
