Banana Date Smoothie

My favorite falafel shop, Taim, has not only the best falafels around, but also incredible smoothies and juices. One of their specialties is a banana and date smoothie. Great idea right?
A homemade version is cheaper and just as tasty, if not even more so, with the addition of a little vanilla. It turns out that with a little soak in some water, dates are pretty easy to blend, and their sweet molasses-ey flavor is just right with the bananas.
