Another drink that I've been making for years, but wanted to try in its milieu* is a Pimm's Cup. You probably don't have a bottle of Pimm's No.1 Cup in your home liquor cabinet (confusingly, Pimm's is the name of both the liquor and the mixed drink) but you probably should. It's a easy summer drink to mix one part Pimm's No.1 and 3 parts Sprite.
It's well past summer, but after walking through the Historic New Orleans Collection's "City of Hope: New Orleans after Hurricane Katrina" exhibit, Erica and I really needed to decompress with a relaxing drink in the comfortable dimness of Napoleon House.

New Orleans, LA
* It's American home, anyway. In the rest of world, Pimm's Cup is properly consumed at all-day cricket matches.
