well, like a couple other folks, i have to say "i love it all!" once went on a weekend binge in dallas and had seafood every meal (but breakfast), and nope, never did get sick of fish & shrimp & etc.
buuut: i have a fondness in m'heart for oysters. when i was a wee little girl in corpus christi, i remember going to a restaurant with an oyster bar with the family. mom & my brother were lounging in a table by the bar, waiting for a table, whilst dad was up on a barstool chowing down on the oysters on the half shell. mom was clearly not interested in nasty slimy things like this, so my brother wasn't either, but i have to try everything. i ended up perched on the barstool next to dad slurping down raw oysters with a smidge of lemon at about 7 years old and have loved them ever since.
