I picked up a 16-oz Grande cup for $2.75. The barista asked if I wanted it with cream so I went with that.
For the most part, the Orange Spice Iced Coffee tastes of a refreshingly-cold, smooth, and lightly sweetened iced coffee. The addition of cream and cinnamon remind me a lot of Baskin-Robbins' Cappuccino Blast, which is a good thing.
Overall, I thought Starbucks Orange Spice Iced Coffee was pretty good and mostly interesting due to the cinnamon rather than the orange slices since I found the orange flavor very lacking.
