Friends avoid any restaurant that attempts to serve any champagne by the glass regardless of the price. There is no such thing as “leftover” champagne you can’t put it back in the bottle and even if you could you can’t re-cork it.
According to the so-called “World Court” headquartered in The Hague, only wine produced in the Champagne region of France can be labeled “champagne…”
That’s why my favorites, Piper Sonoma (Curvee) and Mumms Napa (Blanc Noir) show on their labels, They are marvelous products at sensible prices.

If you are served champagne from a plastic corked bottle, you deserve to be scammed…
