In Barçelona the Grasshopper (equal parts Creme de menthe, Creme de coaco, and cream shaken with ice then strained into a Martini glass) is enjoying a resurgence as a popular club hopping drink because it's legal to add a shot of Green Dragon to the mix. It's legal to use and sell Green Dragon, but oddly it's illegal to import it (usually from Colombia/Ecuador).
If you like to get extremely fuzzy-headed, this variation of a Grasshopper is much more interesting than Jaegermeister or Red Bull with vodka. Very soothing and the effect of just one lingers for several hours. It's a happy drink ordered as a dessert after dinner, priming the pump to deal with the crowded bars.
