Walking into this small take-out shop is like taking a step back in time. The small store is dominated by a grill and a lovingly worn counter, with a photo by the door of F. Sestito's Italian-American deli from 40 years ago. Mr. Sestito's daughter, Rosie Sestito, continues to serve Mamaroneck workers with breakfast and lunch staples like eggs and bacon, steak and peppers, meatball sandwiches, Reuben clubs, potato salad and chili con carne.
