My wife's never-fail go-to choice of champagne.
ellis
I used to drink champagne almost every day. Not always the good stuff but decent.
Favorites for non vintage were Mumms, Tattinger, Piper Heidsieck, Bollinger and if I wanted to impress on a first or second date, Perrier Jouet because women love the bottle.
You could buy this boxed with 2 matching painted flutes.

But for everyday consumption Freixnet Cordon Negro Brut. Spanish but very tasty. About $12-15 bottle.
When I first started drinking it, it was $3.99 a bottle!
