Sounds like it was a great dinner. We just had a '90
themed dinner here in DC where we had:
1990 Taitinger Comtes de Champagne Millesimes x2
1990 Bollinger R.D.
1990 Cos D'Estournel
1990 Cheval Blanc
1990 Rieusec
It was fantastic. You might also want to try a '90 Montrose or Pichon Baron - I've read a lot of good reviews about them right now.
