Week in Reviews: RN74

San Francisco Chronicle critic Michael Bauer re-visits Michael Mina's five-year-old RN47, a onetime favorite that had seemingly "lost its edge" in recent years. And the restaurant has rebounded in a big way: Bauer bestows three-and-a-half stars upon chef Adam Sobel, praising the "unexpected surprise" of certain dishes. "Food was so impressive on one visit that I quickly scheduled a follow-up to confirm the transformation. The return visit only confirmed the depth of Sobel's talent." [Chron]
