About 10 years ago my wife and I took a friend to Alain Ducasse New York for dinner. It was during white truffle season and my wife and our friend had the "tartufi di alba" (probably mispelled) tasting menu. I had the regular tasting menu but with some supplemental white truffle items substituted. I think one was a white truffle risotta. In any case the meal was spectacular. And the first time I did a double take at a restaurant bill. And I am pretty jaded in that regard.
