I really like this champagne cocktail, but what do you use, if you don't have Boker's bitters? Someone with some advice? I tried with one dash Scrappy´s chocolate bitter and one dash Peychaud's bitters and is was nice but too chocolate. Tried to repair with more champagne, cognac, and Heering and it didn't work. I assume it is not supposed to be a chocolate tasting cocktail...
