Don’t expect Stephen Hanson to leave his BR Guest restaurant group overnight. Although eater.com yesterday reported “industry scuttlebutt” that Hanson’s 50-percent partner, Barry Sternlicht’s Starwood Capital Group, is pushing Hanson out, Page Six insiders say a formal split could be a long way off — “maybe not until deep into next year,” said one. Pioneering Hanson created hit eateries including Ruby Foo’s, Dos Caminos and Bluewater Grill, and snatched up several Strip House steak joints. But since he sold Sternlicht half the company for $150 million in 2007, the two haven’t seen eye-to-eye, and the tough-willed duo are said to be locked in “rugged” negotiations. Sternlicht put BR Guest up for sale last year and buzz was that Hanson might buy out Sternlicht rather than the other way around. “This is far from over,” an insider said. Eater speculated that James Gersten, president of a Starwood Hotels/Jean-Georges Vongerichten partnership, would succeed Hanson as BR Guest president. Neither could be reached for comment.
