Family Owned & Operated the Old Fashioned Way. If you are looking for a delicious lunch or if you don’t feel like cooking dinner, Rosalia’s Deli has the perfect complete meal. The Deli has the finest Italian cold cuts including choices which are low sodium, gluten free, and have no additives. They are made the way they were 100 years ago. They also have pizzas made in their wood burning oven, home made fresh salads, sauces, and delicious desserts. Josh, the owner of Angelo’s Ristorante and Banquets, came up with the idea for Rosalia’s, because his family owned a deli in Sicily, and there wasn’t an Italian deli in Elmhurst. Angelo’s Ristorante is named for his father and Rosalia’s is named for his mother. His children are carrying on the family tradition of serving up delicious Italian meals.
