Wandsworth (South London News) May 5, 2026 – Adam Byatt is set to open Rosina, a new Italian-inspired restaurant in Wandsworth, with the chef framing the project as both a personal step and a neighbourhood-focused opening. As reported by RestaurantOnline, Byatt’s first professional venture into Italian cooking will open this summer in the heart of one of his favourite London areas, close to Wandsworth Common and the village.
Why is Byatt opening Rosina?
As reported by RestaurantOnline, Byatt has spent more than 20 years running Trinity in Clapham, and Rosina marks a move into a cuisine he has long loved cooking at home for his family.
The restaurant is named after his daughter, Rosie, which gives the project a personal link that sits alongside its commercial launch.
The concept is also intended to keep his existing neighbourhood style, with familiar team members joining the new venue.
What will the restaurant offer?
Rosina will include a main dining room, a stand-alone bar, a terrace and a private dining room with its own terrace, according to RestaurantOnline.
The restaurant will have 50 covers inside, plus space for 25 more on the terrace. It will operate daily, with lunch and dinner service designed around a compact but regular trading pattern.
What will be on the menu?
Byatt says the menu will draw on quality produce, wines and recipes from across Italy, while also using ingredients sourced in the UK. In the RestaurantOnline report, he described the food as a tribute to Italian cooking and said he wanted the experience to leave guests feeling better than when they arrived.
CODE Hospitality also reported that the food reflects what he has been cooking for years at home for his family, even though it is a departure from his usual British and French restaurant background.
Who is Adam Byatt?
Byatt is best known for the Michelin-starred Trinity in Clapham, and RestaurantOnline says he also runs Brasserie Constance, Bistro Union and Charlie’s at Brown’s Hotel in Mayfair. CODE Hospitality described him as classically trained and noted that his existing restaurants are associated mainly with French and British cuisine rather than Italian cooking.
The move into Rosina, therefore, represents a notable expansion of his restaurant portfolio, rather than a complete change of direction.
How did Byatt describe the project?
RestaurantOnline quoted Byatt as saying he wants Rosina to make people feel better when they leave than when they arrive. He also said he wants diners to notice, even if only indirectly, the “thousand small things” that help shape the experience.
That framing suggests the opening will be positioned as an attentive neighbourhood restaurant rather than a formal destination dining room.
Background of this development
Rosina builds on Byatt’s long-running reputation in South London dining, particularly through Trinity in Clapham, which has been a key part of his career for more than two decades.
The restaurant also follows a wider pattern in London hospitality, where established chefs expand into new concepts that are more personal or location-specific. CODE Hospitality said the Wandsworth site is “just down the road from Chez Bruce,” placing Rosina in a competitive area with a strong restaurant identity.
Prediction for diners
For diners in Wandsworth and nearby South London areas, Rosina is likely to add another neighbourhood option with a chef-led profile and a lighter, Italian-focused menu. Its daytime and evening opening hours, plus terrace and private dining space, suggest it may appeal both to local regulars and to people booking for small gatherings. Because Byatt is bringing members of his existing team, the restaurant may also attract guests who already know his style and want a familiar standard in a new setting.
