I think MRM gave you the best answer.

other thoughts include Krug (some of which really IS good) and Pol Rogers

I like the various Veuves also.

If your friends are really interested in Champagne, then have what are called "grower's Champagnes" and do a comparison on the different parts of Champagne. They do taste different, esp. south and north parts.

After they are too drunk to notice, bring out the Cremants, followed by the Proseco, Calif. Rodoerers, and follow up with cheap beer and mezcal.
