Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x5 inch loaf pan, set aside.

In a large bowl, combine flour, baking soda and salt, set aside. In a separate bowl, cream together butter and sugar. Stir in eggs, vanilla, and mashed bananas until well blended. Stir banana mixture and chocolate chips into flour mixture; stir just to moisten. Pour batter into prepared loaf pan.

Bake in preheated oven for 50 to 55 minutes, until a toothpick inserted into center of the loaf comes out clean. Let bread cool in pan for at least minutes, then turn out onto a wire rack. Slice and serve warm!
