Here's the fictional foods list I'd be down for trying out:

1) Brahmin Burgers (from Fallout 1, 2, & 3 [I hope!]) - Sure to be twice as tasty as Buffalo burgers, right?

2) Melange aka "Spice" (From Dune) - If you have some you can bridge space and time. You can see in to forevah!

3) White Flower (from Super Mario Brothers) - You can spit fireballs afterwards... and they bounce!

4) Blue Milk (from Star Wars) - I've always been curious as to how good it tastes. A part of me believes it is exactly the same as the after-milk from Boo-Berry cereal.

5) Powerthirst (from CollegeHumor) - I'm intrigued by a drink which claims I can win at Sports, Art, and Arson, and have 400 babies that run like Kenyans. More importantly I wonder what an additive of Anna Kournikova will do to a person.

6) Celestial Wine (from Exalted, the RPG by White Wolf Games) - One sip and you live for 500 years, drink a bottle and you gain immortality, a great buzz, and absolutely NO hangover afterward.

7) The Peaches from the Peach tree of Wisdom (from Kung Fu Panda) - I have to admit that seeing them made me wonder if peaches from the tree of wisdom are juicier than those from a normal tree.

Cyberdine is the corporation that makes the Skynet AI, which blows up the world and makes cybernetic assassins called Terminators.

Arthur Dent, in case that was missed, is the protagonist to Douglas Adams "Hitchhiker's Guide to the Galaxy".

Very Classy Stuff.
