The Pan Galactic Gargle Blaster is a cocktail described in The Hitchhiker's Guide to the Galaxy as "the alcoholic equivalent to a mugging; expensive and bad for the head.". Apparently, drinking one is like "having your brains smashed out by a slice of lemon, wrapped 'round a large gold brick."
Isn't that perfectly awful?
Kerry-Anne ordered this drink at Eastwoods Lounge, near Tyger Valley Center. She reported that the Pan Galactic Gargle Blaster never had the alleged brain-smashing effect on her and was fairly tasty, albeit just a little too sweet for her liking.
