Orland Bakery at 143rd and LaGrange Road (next to Randy's Market) has delicious fruit filled cakes, but they are more expensive than bakeries located within the grocery stores.
I also have had delicious cakes from the full service bakery located within Walt's Groceries at 161st and Harlem. They do a beautiful job decorating their scrumptious treats, and they are very reasonable, and nice to deal with. Also, if you are hosting a small gathering, and you don't have time to bake, they will put together a very reasonably priced tray of fancy pastries for you.
