I've never had the pleasure but I used to be in business with someone who claimed to have had the opportunity. He accepted but bowed out when confronted by the realisation and smell of what he'd let himself in for. He apparently went green, excused himself hurriedly and was violently ill.

If you're in the market for some edgy foodstuffs, then you should try Casu Marzu cheese. Try Googling it to see what's involved!
