I've had white truffles at several dinners, paying a lot but not any extreme prices (89 a person or there about)
I really really enjoy truffles, but I would NOT spend hundreds or go out of the way to dine at a place with them by any means, they are a delicate flavor that really is not worth an insane premium.
Michael Mine features them quite often, and that is where I have twice had them, but the free duck fat frenched fries that were served were possibly more memorable

That is a white truffle bread, pretty good but my tastes say that was more truffle oil than real truffles. Most things with truffle oil are very horrible, as people use it wrong, and it is generally flavored not real truffles.
