Ouzo - Greek
I'd heard about ouzo forever, without really knowing what it was.  Basically, Ouzo is a Greek hard liquor with a very strong licorice flavor.  (Much like Sambuca.)  If you like licorice, you will enjoy it.  Warning - Ouzo comes in small glasses, but it's strong.  But it's so tasty and warm inside...!

Would I try again?  On the right night, it would be quite nice.
