Personally, I like:
Turkish coffee, I received a cezve as a gift, Lots of crema (they don’t call it that, but it’s very frothy).
Coffee soda. Double shot espresso in a glass of ice, add soda water to taste. Great when it’s hot out.
Coffee milk. Same double shot in a glass of milk, with lots of sugar. Reminds me of my childhood. The official state drink of Rhode Island.
Since I live in Vietnam these are not exactly less common here but would be back in the States:
