I really like their upside-down sugar-free, fat-free iced Caramel Macchiato. The only thing with sugar in it is the caramel, so the calories are very low in that drink (though I confess that I ask for extra caramel, thus upping the calories a bit!).
I also like their French Vanilla iced coffee with lots of soy milk (their soy milk has a vanilla taste to it, so it complements this drink wonderfully and actually tastes better with it than milk does). I always ask for one extra pump of the sugar-free vanilla and one extra pump of the sugar-free hazelnut in my venti-sized drink.
In the wintertime, however, I throw all calorie cautions to the wind and indulge in the Pumpkin Spice Latte. It is my current favorite drink from Starbucks! This drink tastes best with soy milk for the same reason described above (seriously, I've compared--and I normally prefer regular old skim milk, but not for a select handful of drinks).
I also love the Salted Caramel Hot Chocolate, Yaoi Pervette! It is amazing. They introduced it for the first time four years ago. Then three years ago, they did not have it during the winter months, and I was so bummed. Luckily, they reintroduced it last year. I am hoping it makes an appearance this year, too. It is rich enough that it still tastes great made with skim milk.
I am also hoping that they will reintroduce
Chantico, another incredible chocolate drink that they used to have several years ago. (I think it was probably my very, very favorite drink that they ever sold.) It came in a very small cup and was just intensely thick and rich and chocolatey!
Oh, and when we first started going to Starbucks over ten years ago, both my and my husband's favorite drink was Cinnamon Spice Mocha. Sadly, they quit carrying the cinnamon syrup used to flavor that drink years and years ago (the cinnamon syrup they have now is not the same, and we just don't like it). But neither that nor the Pumpkin Spice Latte nor the Chantico were exactly low calorie drinks, so I'm getting way off topic here! Hmmm, I need to make a visit to Starbucks soon . . .
