My wife loves foie gras. I can tolerate it, on a cracker, but I don't much like it, I let her have it all, same with caviar, which she likes, not so much the cheap fake stuff.
I can eat caviar, but I don't really like it, so I let her have it. Paying $100 or more for a tiny portion of black fish eggs is not my thing.
I do enjoy snails, raw oysters, smoked salmon, and a few other "delicacies".
