With Project Runway having decamped to Lifetime, Bravo is making the most of its remaining buzz-generating reality competition, Top Chef. Last week, the network announced a second season of Top Chef Masters, which did well for the channel this past summer despite mixed reviews for its curtailed format. And this morning Bravo announced another spin-off, Top Chef: Just Desserts, which will pit pastry chef against pastry chef, last-man-standing-style. Coming up, no doubt: Top Chef: Special Victims Unit.
