Cafe Miranda, a landmark Rockland restaurant that has served innovative, fun food for nearly 30 years will close on Saturday, June 25, “failing some miraculous turn of events,” according to owner and founder Kerry Altiero. The reason is the labor shortage, he said, and the specific miracle he is seeking is to have two qualified cooks land on his doorstep, ready to get to work. At this point, that doesn’t seem very likely to happen, he said. “I think it’s very sad that we’re closing,” Altiero, 66, said.
