My FI and I are thinking of having a cash bar to save money since an open bar can be a really big expense. My FI thinks a cash bar isfine, but I am worried. I have read in a number of differerent places that cash bars are unacceptable since your guest should not have to pay for anything at your wedding. I am also aware of the option of offering bottles of wine at the tables or having certain signature drinks be free to guests. Would this actually save money? I'd love to hear what other people are doing for their bar.
