I've recently learnt that most Starbucks have filter coffee as an off-menu item. It's still Starbucks but it's so much better than their "Americano". Unfortunately many will refuse to make it for you (presumably because it's more effort).
It's not that espresso can't be good, but for most places this is the cheap, low effort, coffee-on-demand. And in most of southern Europe (Italy, France, Spain) the taste seems to be for burnt coffee that all tastes the same.
Also, it really annoys me that if you order two drinks (like a café con leche in Spain) they'll split a double shot into two cups with one getting clearly more coffee than the other. It's a 50% chance you're going to get the weak brown milk.
