I would say Foie Gras. Popular with snooty crowds, how it's made is horrible, supposedly doesn't taste that great either. Never had it, but that'd be my main vote.
On lobster. Absolutely LOVE it. I ate it 4 of the 6 nights of our honeymoon and it was heaven. Only thing is it's disappointing how much they charge for it. Almost makes me want to move to Maine.
