We have a full open bar with our venue although, besides the champagne toast, they do not offer champagne. My Grandma only drinks champagne, for this we checked and our venue OK-ed us to bring in a case. We also decided to have our signature cocktail champagne with cotton candy (our venue is on the merry-go-round pavilion). I rarely buy champangne unless for a special occasion and will get a fairly nice bottle, although since we will be buying a case or 2 I’m hoping to find a more cost effective champagne. Any suggestions?
