Mashable writes about Blind Pig in Soho, London serving Harry Potter Butterbeer.  The ingredients contain many of my favorite things:

“Half a Pint o’ Buttah contains Monkey Shoulder scotch; Kam and Sons, a botanical spirit distilled with ginseng; thyme liquor; butterscotch; and beer.

Might have to find a reason to go try this.  EPL anyone?
