So far it hasn't been successful.
Starbuck's pumpkin latte
It gets worse and worse every year. Zero pumpkin flavor this year. Zero spice. It is just sickenly sweet,. It was a waste of 300 calories.
McDonald's Harvest shake
To it's credit it doesn't call it pumpkin. They don't have the ingredients on line yet, so can't say what is in it. It is pumpkin orange, but it just tastes of pumpkin pie spice ... and brown sugar ... or molasses. Yes, that's it ... it tastes like HFCS crossed with molasses. Not pleasant. My throat burnt for about 15 minutes after drinking it.
They also have some sort of apple/caramel sundae.
That's all I've tried so far. Who else has tried a fall food menu item?
