I have a reputation as being someone who will eat almost anything, but I don't like capers very much, and I'm massively hoogely allergic to raw celery (which is a pity, because celery / apple / walnut salad was one of my favourite things, prior to the anaphylactic shock incident).
I'm not keen on milk by itself, don't like tomato juice, I won't eat McDonalds or similar, and the wafting scent of KFC and other fried rat shops makes me heave.
