Its certainly worth getting just for the novelty factor.I drank it years ago on tap in NewYork and more recently in Dublin and can say its drinkable but by no means to everyones tastes.
Its a really cloudy brew and looks the real deal but i have to say im not mad about the orange hint it has to it, would be far nicer without it i reckon.
I managed to acquire two Bluemoon glasses that take pride of place amongst my rather small collection of beer glasses.
