Never had a real truffle but I understand they are crazy expensive. We eat at this place once a year I guess. It's definitely one of our favorites in SF (and there are plenty of nice places) but this is by far the most expensive meal they have ever offered. They are unique in that they have a very well stocked wine shop attached to the restaurant. If you see a bottle you would like with dinner they will sell it to you and open it table side for a small corkage fee and the wines are not marked up. They are regular MSRP that you would find at any Total Wine or similar.
