I'll try almost anything once!

I don't drink beer - don't care for it at all. If really pressed to taste something that is supposedly really good beer, I'll take a sip, but I have yet to find one that I think is drinkable and I'd never be able to gag down a whole glass. I think it has a *nasty* aftertaste.
Most fish roes, green bell peppers and arugala are on my will politely eat, but really rather not have list. I would likely refuse a whole stuffed pepper, but can handle it if its in another dish.

Sea cucumber? I've had it prepared really wonderfully at a sushi bar. The way Yoshi does it, I wouldn't really call it gelatinous - its even a bit crisp. Its a real treat when he has it.
