Great in theory, I suppose, but doomed to failure simply by virtue of the fact that it's Starbucks...I spoke to my Los Angeles based fiancee this afternoon about this...she apparently asked a "barista" at her local Starbucks about it, and he happily informed her that a) it comes in a Grande size cup (16 ounces/475ml) and with approximately 1 INCH of foam. So it doesn't sound too flat to me...also is WAY bigger than you would ever get here, and still only with two espresso shots at that size...so, sounds like a bit of a fail to me...
The worst part is probably that we'll have Americans coming here telling Uus that we're doing it wrong based on the assumption that Starbucks way is the right way...
