There are a few things, like heart and tongue, that I've never eaten so can't say whether I like them. I just can't drink milk from a glass, tho it's okay in cereal. I do remember in elem school (early 60's) getting little glass bottles of milk for 2 cents and it was cold and yummy! Other than milk, I eat and like anything. Poultry isn't a favorite, especially white meat, but it can be edible! I think it goes back to my childhood where we had mostly beef, pork, fish, and all kinds of veg.
If you want to talk about picky, my DH won't eat rice or noodles, any veg except green beans, casseroles, Oriental food (tho I tell him it's just meat and gravy!), hot cereal, fish or any seafood except tuna, ... he's happy with just meat, potatoes, and bread! My DS won't eat meatloaf, mayo, or tuna and that's ok with me since he'll eat and/or try anything else.
