Just read the thread over in site talk about all the press reports and found a side discussion about banana milkshakes. Well it just so happens I had a delicious one last Friday at the Brooklyn ice cream place (dont know the official name, but it was discussed here recently)on the East river at the end of the street where Grimaldi's pizza is, and right next to the River cafe.
It was a special and I chose chocolate ice cream in my milkshake. it really was delicious. However, when I make them at home for myself, I add some kahlua, chocolate syrup, vanilla ice cream and banana. That one cant be beat!
