Just get an espresso maker. Nothing fancy, any kind will do.
Make the espresso.
Fill a glass with ice.
Pour your espresso in.
Top it off with iced cold milk.
You can make it with vanilla extract or get flavorings at any specialty store.
Every time I walk into my girlfriends house I make one right off the bat. I also make one every morning at home. To boot it's all organic at home!!
May this give you some hope for the future.
