A great way to celebrate Opening Day of the baseball season is to go to East Rutherford, find 900 Paterson Plank Road, and hit Annabella’s House of Mozzarella & Italian Tavern on March 28. Folks have been raving about their food since they opened 21 years ago. As an added bonus to your rigatoni, a real live piano man, Hal Keshner, will tickle the ivories.
