It's espresso mixed with milk that has been [supposedly] infused with floral Tahitian vanilla syrup, then flavored with vanilla bean sauce, topped with vanilla bean pod sprinkles.
It's quite good. The vanilla flavor has the right richness and intensity. Nothing floral about it though. The drink is not too sweet and has enough coffee depth in the background.
