Nope, you're not having déjà vu: Thierry Rautureau was indeed on Season 2 of Bravo's Top Chef Masters. And now comes a promo proving The Chef in the Hat is returning to compete on Season 4, which premieres July 25th.
Rautureau, the chef/owner of Rover's and Luc, is the only cheftestant from the Northwest, and Chris Cosentino of San Francisco's Incanto is the only other West Coaster in the group.
In other Top Chef news, rumors have been swirling for months about whether Season 10 of Top Chef will land in Seattle or Portland (it seems that the two cities are yet again in competition). I'll let you know when I hear anything more substantial, but do let us know in the comments if you've seen suspicious film crews around town.
