This trip Guy discovers some hidden gems. In Stone Harbor, N.J., a fish shack flying in Paco Paco fish from the Amazon for a Brazilian specialty. In Long Island City, N.Y., a 14-seat joint doing everything from wood oven pizza to a lunch counter with all kinds of sides. And in Santa Rosa, Calif., a volunteer-run brunch spot where kids are cooking up huevos rancheros with roasted pork.
