This year is an occasion for celebration. One of Eagle Rocks best restaurants is 50 years old. Even the possibility of this happening would probably not have occurred to Sam and Jennie Martorana when they opened Casa Bianca with Sam's brother Joe in January 1955. Sam found a corner storefront in eagle Rock that was owned at the time by Charlie Morreale. Using the skills learned at his fathers grocery business and working for Tony's Pizza in Chicago, he opened a restaurant and deli. The quality of the restaurant is based on personal attention and consistency. All of the food is made from scratch on the premises. The family is vigilant to maintain the food just as it has always been. Old customers can expect to have the same quality family experience as they remember. A surfeit of good publicity has made it difficult to get in without waiting, but a little planning and perhaps a call ahead can ease the way.
