I'm starting to wonder if Starbucks serves the same stuff in Europe that they do in the States?
My experience of Starbucks in Europe (England specifically) is far different to that in the States. I usually get espresso based drinks at Starbucks, fwiw. I never had two cups that tasted the same in England, there was no consistency between locations or barristas. In the US, they generally taste the same everywhere, albeit burnt.
With that said, I don't visit Starbucks overseas unless I have to. The local cafes nearly always serve better cups at competitive prices.
