I love my Bento Box that I have attached to my bicycle on the top tube. It is so handy to carry small snack items while you are out riding. Everything is right there in front of you and you don't have to stop or reach in hard-to-get-into back pockets of your jersey.
See my story and photos on my blog. The post is titled: "A Bicycle Lunch Box"
