fake banana flavouring is pretty yuckie.. the starter for this thread.. That said I'll eat just about anything. The only exceptions I can think of are
tripe
tendon
chitlins.. the smell alone hurts me.

other than that there's things I'm not a fan of or wouldn't search out on my own but if I'm hungry and it's in my way.. It's gonna get eaten. After 3 disapoints in a row at starbucks though I doubt I'll ever pay for a baked product there again. They've consistently disapointed me..

SPAM is the best though. fry it in some soy sauce. slap a slab of rice on top. wrap it up in nori. perfection. Long Live The Spam.
