Leonardo DiCaprio and a circle of A-list friends slipped into Carbone London for a private preview dinner Monday night, days before the Italian-American eatery is set to officially open to the public in London’s Mayfair district. A source described the gathering as discreet, with DiCaprio joined by Kate Moss, Sean Penn, Benicio del Toro and Tobey Maguire for a sneak peek of Major Food Group’s new London menu.

The group was said to have dined together, unobtrusively sampling a preview of the restaurant’s offerings, including familiar favorites such as Spicy Rigatoni Vodka, Veal Parmesan and tableside-prepared Caesar salad, along with dishes created specifically for the London location. DiCaprio and Penn are co-stars in the upcoming film One Battle After Another, which is slated to premiere next Friday, while Maguire and Moss have long personal connections with the actor. Moss, in particular, has a friendship with DiCaprio dating back to the early 1990s.

The restaurant’s private preview preceded an official launch sequence that saw Carbone London host a star-studded soirée on Tuesday night, with Major Food Group co-founders Mario Carbone and Jeff Zalaznick on hand to welcome guests. Among the attendees were actress Minnie Driver and music industry executive Lucian Grainge, as well as hotelier André Balazs, investor Lucy Guo and Authentic Brands Group founder Jamie Salter. An insider said Zalaznick opened the room with a welcome speech before guests toasted the first UK outpost with glasses of Barolo.

Carbone London’s interiors were designed by Ken Fulk, with a moody lighting scheme and towering florals that complemented the dining room. The London outpost will feature menu items exclusive to this location, and reservations began rolling in on the eve of its public opening. Carbone, which originally debuted in Manhattan’s Greenwich Village, has since expanded to Las Vegas, Miami and Dallas, with further outposts in Hong Kong, Doha, Riyadh and Dubai.

London marks a continuation of Carbone’s global growth under Major Food Group, as the brand brings its signature Italian-American dining experience to a new major European market. The official public opening follows a private preview period and a Tuesday night launch party that helped set the tone for the UK debut. The restaurant’s design, menu and guest list reflect a blend of celebrity culture and high-end hospitality as Carbone continues to expand its footprint beyond the United States.

With reservations already being accepted ahead of the public opening, Carbone London is positioned as a focal point in Mayfair’s growing dining scene. The location joins a roster of international sites in Major Food Group’s network and signals the brand’s intent to extend its signature dining concept to a broader audience in Europe. The starry turnout at the surrounding events underscored the prestige attached to the London launch, even as staff and guests emphasized a discreet, invitation-only atmosphere during the pre-opening phase.

As the doors open to the public, Carbone London sits at the crossroads of celebrity culture and culinary branding, extending a model that has drawn appraisals for its familiar yet refined dishes and bold design. The restaurant’s UK debut comes amid a broader trend of American hospitality brands expanding into Europe, bringing a recognizable concept to Mayfair’s affluent dining market. The next chapters for Carbone London will likely hinge on how well the London menu translates to local tastes while preserving the high-energy dining experience that has characterized the brand since its Manhattan beginnings.
