I went to T.G.I. Friday's for the first time last winter and low and behold, what was on the beverage list than my two favorite beers (Guinness and Blue Moon) mixed together with the lighter beer on the bottom and the dark one floating on top! They called it the Eclipse, but turn's out it's actually called a Black & Blue, a cousin to the Black & Tan. This drink compliments St. Patrick's Day nicely and will be a nice sipper between chugging Irish Car Bombs!
