Yes, it IS as delicious as it looks. Quite simple too:
1 Pint Guinness
3 scoops of vanilla ice cream
Godiva chocolate shavings
1 edible chocolate straw (this is a must)
First, put 3 scoops of vanilla ice cream in a glass. Slowly pour in the stout while angling the glass. Sprinkle with shavings, and put the straw in. Sometimes, heaven just reveals itself on earth.
For an added bonus, you can always put in some chocolate syrup or liqueur.
