I relate to this 100%. Same background, lived in several places before ending up in London.

You can find good roasted coffee of many types in most of these places.

But if you need an espresso or any other Italian styled coffe. Nothing can beat Italy.

I admit one exception: Portugal. In a long trip to Lisbon I’ve done I had some of the best coffee there !

Edit: still using my 18yr old Bialetti for most of my coffee here and buying coffee when going back occasionally (ever brought back a trolley full of coffe through airport security checks?). Only reliable way so far to have decent coffee.
