Continuing with the "numbered cocktail" theme, I think this is the first drink of the Happy Hour series I've posted that's served in a shot glass.
This is the 747. Not sure why it's named after an airplane, but some cocktails have mysterious origins. This is made with Kahlua, Bailey's Irish Cream, and Frangelico. From those ingredients I'm sure you can tell immediately what it might taste like and if you'd like it or not.
