Never had it, but I have had La Tache, Richebourg, and Romanee St. Vivant from DRC, as well as their Echezeaux and Grands Echezeaux.

La Tache is pretty damn special, as is Richebourg, but frankly, the prices for the Domain Romanee Conti burgundies have gotten absurd since the 1990s. And since other fine producers also make great wines from the Richebourg vineyard, as well as Echezeaux and Grands Echezeaux, and those wines can be bought for 3 digit prices, rather than the 4-digit or even 5-digit prices per bottle of Domaine Romanee Conti's better wines - that's about as far as I'll splurge on a bottle of burgundy nowadays.

If I was going to drop many hundreds of dollars on a single bottle of Burgundy, I'd be more likely to get a bottle of one of the following:

Musigny from J.F. Mugnier or

Richebourg from one of the numerous members of the Gros family
