We live in Park Slope in Brooklyn and our neighborhood is well served by three food delivery services (Grub Hub, Delivery.com, and Seamless), all of which deliver from local eateries. I suggest you try one or more of these sites and enter your address and see what kind of delivery options they offer for your neighborhood. You might find something you really like, and delivery doesn't cost you anything.
There are tons of places near her like Roma Pizza on the corner of 88th and 3rd. However if I were to recommend one place it would be 3 Decker Coffee Shop on 2nd Ave and 91 St. They have an extensive menu, serve good comfort food and are very reasonably priced.
