(David Moir/Bravo) "U.D.O." or "Unidentified Dominican Object": that was Oakland chef Nelson German's sci-fi solution to a movie-themed challenge on this season of Bravo’s Top Chef. The dish was a variation on a pupusa, a flat disk made of corn, jerk pork and candied yams. German, who is Dominican American, was the only California contestant on the show this season. “The pressure was on,” German says, in the kitchen of his newest Oakland restaurant, SobreMesa. “The minute you see that big Top Chef sign for the first time, it's like you're a line cook all over again. I just kept thinking about why I'm here. It's representing a movement, showing a person of color can run beautiful restaurants and bars and really be a fantastic chef and give back to the community.”
