Bananas are only found in Jungles, which makes them kinda difficult to explore, but it also gives you an unique opportunity - you can use the tile without any development whatsoever! Their initial yield is +3 (thanks to the Jungle tile), and a Granary adds another point of ; then we get the 2 from the Jungle tile when you build a University! You can also build a Trading post improvement, keeping the Jungle, for another 2 points of and an awesome natural yield!
You can also decide to develop the Bananas with their proper Improvement, the Plantation, which will improve further their yield. However, to do so you'll need to chop down the Jungle and revert the tile to its base terrain, losing the bonus. So, think carefully what do you need for your nearby city - a big booster, or a more diversified yield.
Finally, the Sun God Religious Belief adds another point of food bonus.
A banana is a popular tropical fruit. It, and its cousins the plantains, are an important part of many tropical peoples' diets. Originating in Southeast Asia, the banana is now cultivated around the world.
