Crystal is overrated as well. (A lot of similar and even better tasting champagnes at a fraction of its cost). If you want luxury and class, go with Krug or Bollinger... that'll knock your socks (and her panties) off.....

Other nice recommendations; Veuve Cliquot La Grand Dame Rose or vintage 1990

Dom Perignon Vintage 1996
Perrier Jouet Belle Epoque
Krug NV Grand Cuvee

etc.
