Hi there!
Thanks for the response!
But really, probably the best Banana you can eat in your life is the "Banana Ouro" type.
Try this site below. It is just for this kind of bananas. Sorry, it´s in Portuguese. If you need, I can translate for you.

Also, there´s one kind of bananas I forgot: "Banana Terra" (like ground bananas. Not very sweet, good with main courses. (like fish or meat)
