Gordon Ramsay surprised staff at Nobu in Southampton Saturday night by paying an impromptu visit to their kitchen. The “MasterChef” and “Hell’s Kitchen” supremo, famed for terrifying chefs with his verbal roastings, sauntered into the kitchen at the new Nobu at the Capri, which “was a huge surprise to many of the staff,” a source told us. But Ramsay, we’re told, was friendly and complimented the crew on their food before returning to his table of friends. Also there was rock icon Courtney Love.
