"Strago: Old cheese"

I was going down your list and when I came to that one I spit my water all over the computer screen....HILARIOUS

"Edgar: Sweedish Fish"

I was actually eating those as I read this... freaky, seeing as how I'm usually a health nut. But oh well, I'm not getting ready for a show or anything right now, so I can cheat ... anyways, I'd have to associate Edgar and Setzer with some sort of high class or sensual foods, like chocolates and cherries with wine..... something that a playboy would be into. Outside of that, the only ones I could even venture a guess with:
Umaro: Italian Ice
Sabin: obviously some sort of animal protein
Gau: Raw fish
Strago: can't get any better than moldy old goat cheese lol

And when I say Gau: Raw fish it's because you can almost picture him holding it and biting it's head off... if you forget about his little fear of water (not wanting to jump into the trench and all in WOB)
