Home on the 'Top Chef' Range

The setting might have changed on "Top Chef Las Vegas," but the results only varied slightly. Mattin was sent home after making another subpar dish -- while Ron and Robin remained in the bottom. Ashley and Laurine took a detour to the top-four, while the Voltaggio brothers continued to rule. (The show might have to be renamed "Top Voltaggio" if this continues.)

The best home-cook tip I got was Laurine's grilled potatoes, a tip I frequently employ (they're great in the oven too).
