Not every cafe will be featuring the product (called Starbucks Via) that will come in slender packets (oh, that will make it attractive!) and due out in March. Well, if you want more convenience, there it is, just pour the stuff in hot or cold water as you prefer, and it's ready to drink. When I think instant, I think, well, yuck!
